All doors of manholes, hand holes and sight holes and cleaning plugs and all caps in the headers and mud drums of water tube boiler, all fire bars bearers front plates, bridge plates, fire bridges, brick arches, oil fuel burners and mechanical stoker fittings shall be removed. All valves and cocks comprising the boiler mountings shall be opened up and taken apart and the valves or cocks ground, when necessary, before the inspectors visit.(b)Preparation for Hydraulic TestThe chests of all mountings subject to steam pressure shall be in place and shut tight or blank flanged. The safety valves shall either be jammed down or removed, and the chest-openings blank flanged. The attachment for the inspectors pressure gauge and the nipple for connecting the inspectors test pump hose shall be in order. All doors shall be properly joined and tightened up. The boiler shall be completely filled with water, care being taken to allow all air to escape and, if possible, a preliminary test not exceeding the working pressure of the boiler shall be taken before the inspectors visit to test the tightness of the joints.Preparation now required(A), (B),______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Form 'C'General working of Boilers-Instructions for boiler attendants(Rule 7)General working of boilers-Instructions to boiler attendants. - These instructions should be frequently and carefully studied, with a view to keeping in mind the precautions to be observed, and the ordinary procedure to be followed in the safe working of boilers. 'Precautions before starting the fires. - Before starting the fires in a boiler, the attendant should-

(1)see that there is sufficient water in the boiler and that gauge cocks are working freely,

(2)ease safety valves, or open cock on top of boiler to allow air to escape,

(3)see that the blow-off cock is fully closed and tight,

(4)see that the safety valves and feed check valve are free and workable,

(5)see that water is not leaking from any part of the boiler,

(6)note if the pressure gauge pointer is at zero,

(7)see that the feed pump is in working order.He must not rely on the supposition that the water he has previously put in is still in the boiler, as it may have run out without his knowledge through a leak or open cock, nor can he be sure that the gauge glass shows the true water level until he has tested it. This is done in the following manner, shut off the lower gauge cock and empty the glass by the drain cock, then shut the drain cock and open the gauge cock, if every thing is in order, the water will then rise in the glass to the same height as before.Raising steam. - In getting up steam in all types of boilers, the operation should be as gradual as circumstances will allow. Nothing turns a new boiler into an old one sooner than getting up steam too quickly. Forcing the fires when starting work if liable to cause of the steams striving and tubes of the boiler. In the case of large boilers generally steam should not be got up in less than six hours. Before getting up steam the water level should be observed, to ensure that the water is at the proper height in the glass the pressure gauge noted, and the safety valves tried to see they are free. The blow-off cock should be examined to see that it is completely shut and tight.Pressure gauge. - The pressure or steam gauge should be kept in order, and be in such a position as to be easily seen by the boiler attendant. There should be a plain mark on it showing the highest pressure allowed for the boiler, and the dial should be kept clean so that the figures may easily be read.Steam pressure. - Ordinarily the safety valve will prevent the steam from rising much above the working pressure, but if the steam gauge shows so rapid an increase of pressure as to indicate danger of exceeding the highest limit, water should be immediately fed into the boiler and the dampers partially closed in order to diminish the effect of the fire. If however, the water has fallen so low that there is danger of an accident from this cause, the fires should be withdrawn before feeding in water, the safety valves eased, and if the engine is at rest, it should be started so as to reduce the pressure.The safety valves are provided to guard against over pressure. They should be moved by hand every day so as to prevent them from sticking. If moved only occasionally, they are liable to leak.The valve can be tested by slowly raising it a little, and when let down, it should close perfectly tight. It should never be opened by a sudden knock or pull. If it does not close tight turn it on its seat until it fits, or when its construction does not permit this, raise it slowly a few times and let it down again, but on no account must the valve be screwed down further or loaded more than what has been allowed by the inspector.Safety valves must be over loaded, and spring valves should have ferrules and other provisions against their being screwed down too far. In case of an accident resulting from wilful over loading the culprit might be held criminally responsible at the official enquiry or in quest.Low Water Safety Valves. - If there is a low water safety valves test it occasionally the lowering the water level to see that the valve begins to blow the right point. It should give warning "before" the water level has sunk too low, and before damage can be done. When the boiler is opened examined the floats and lower and see that they are free and that give the valve the full rise. With the ordinary type of high steam and low water safety valve the float should be down at its lowest position and are valve full open when the boiler is empty.The Water Gauges. - These will be kept best in order by frequently blowing through. The cocks are thus kept in good working condition without leaking. Blow through the drain cock at the bottom of the gauge, and shut and open the steam and water cocks every few hours. These cocks should be blown through more frequently when the water is dirty. Should either of the Passages become choked, or whenever the water in the gauge glass moves sluggishly, the passage must be cleaned. This is best done with a wire. The gauge glass is so arranged that its top cock connects with the steam space and its bottom cock is below the water line. The water line will ordinarily be near the centre of the glass tube. Always test the glass water gauges thoroughly the first thing in the morning and at the commencement of every shift. This is done by first opening the drain cock, then shutting the upper cock which should give water, the upper cock should then be opened and the bottom cock closed which should give steam during this test the drain cock should be kept open.If water and steam do not appear in proper order the cocks are choked and the passages should be cleaned. To lessen the risk of breaking to the gauge glass the water cock should always be reopened after the steam cock.Gauge glasses with a narrow white strip running the whole length of the glass on the side next the boiler are recommended, as they show the water line more clearly especially when the water is dirty.The Indian Boiler Regulations require every water gauge glass to be fitted with a guard to prevent injury to the attendants. See that it is always in place, and clean, when there is steam in the boiler.Special note. - It does not follow that there is plenty of water in the boiler because there is plenty of water in the gauge glass. The passage may be choked and empty gauge glasses are sometimes mistake for full ones, and explosions have resulted therefrom. Hence the importance of keeping the gauge cocks perfectly tight and clean and of blowing through the test cocks frequently.A large number of accidents have been due to inoperative water gauge, and to negligence of the attendant in not carefully reading the water level.The blow off cock. - The blow-off should be used daily if the water is at all dirty or sedimentary, especially with Locomotive type and Vertical Boilers as their narrow water spaces are liable to get choked with mud, which so on hardens into a solid mass. The amount of water to be blown out depends the size of the boiler and can be determined only from experience. When blowing out the best result is obtained, if the water has been at rest for sometime to (say before the engine is started) thus giving the sediment time to settle if the feed water is clean, merely turn the cock on round.The scum cock. - When scum cocks are fitted, if the feed water is dirty a little should be blown-off daily if the water is clean, merely turn the cock round. Before opening the scum cock see that the water is at the height indicated by the water level pointer, otherwise the scuming will be ineffective. Water should be blown from the surface through the scum cock when steam is being drawn off i.e. when the engine or other machinery is working.Manhole and other door joints. - When making such joints, the joining materials should never be of round sectioned packing. Care must be taken that the spigot of the door is centrally placed in the hole as many accidents have resulted from packing being blown out between the spigot and side of hole even when the clearance was only ⅛ inch. The nuts must be carefully and evenly tightened. Further tightening should be made during the process of heating up the boiler when raising steam.Steam pipes. - When properly arranged should give no trouble. Frequently however, they are so designed as to contain packets in which, while out of use, condensed steam accumulates. Such water is exceedingly dangerous and great care should be taken lo see that the pipes are properly drained before the stop valves opened otherwise 'water hammer' will take place even with the best designed steam pipes, and disastrous explosion causing loss of life and property may occur.Scale and grease. - Roughly speaking, scale offers a hundred times as much resistance to the passage of heat as does a similar thickness of steel or iron. A half inch furnace plate covered with 1/10' scale is as efficient a heat retarder as a steel furnace 10 inches thick grease is about ten times worse than scale. In a boiler at work the temperature of a clean furnace plate is only slightly in excess of that of the water in the boiler: but if scale of grease is interposed between the water and the plate, the latter acquires a temperature more nearly approximating that of the flame with which it is in contact. If the fire is fierce (artificial drought) the furnace tube may grow so not that it elongates considerably. If, in addition, cold air is admitted during each firing a concertina action of the furnace tubes place, which is one of the worst causes of boiler wear and tear.Wear and tear can be reduced and the life of a boiler prolonged if scale and grease are prevented from accumulating in a boiler. The combined effect of scale of grease and artificial drought are disastrous, scale also causes waste of fuel.Grease. - A mixture of sedimentary water, soda and grease produces an adhesive scum. Where this suspected the water level should never be lowered below the furnace top unless the boiler is afterwards entered in this scum cleaned off the furnace plate before jiring again.Scale removal. - The customary method is not a satisfactory one. The boiler is emptied and then cooled down by opening all the manholes and the result is that the scale, which would otherwise be soft, hardens through contact with the air, and requires laborious chipping off.A very effective, but slower method, is to retain the water in the boiler until cool, and not to run it out until the mean are ready to enter the boiler with water hose, brushes and scrapers. The scale will then be soft and easily removable.If time is a consideration, the cooling be accelerated by adding cold feed to the hot water in, the boiler and slowly running off the cooled water. Another method is to blow-off the boiler with the lowest possible pressure (not more than 20 lb.) and to keep it closed until cold. The scale will then be easily removed.Treatment of feed water. - Many feed water require soda or other chemical to arrest corrosion or to change the nature of the scale.There is no harmless chemical which will remove scale or sediment when it has once got into the boiler, and the only effective process is to purify the feed water before it enters the boiler. By this means the sediment, and generally too the added chemicals, can be deposited in tanks or in filters, and therefore, never goes into the boiler, excepting when the water obtainably is very good, water purifying apparatus ought to pay any boiler owner, particularly at those works where three or more boilers are in constant work, boiler owners wishing to have definite advice as to the best treatment of their feed water should have it analysed at some chemical laboratory and ascertain the best treatment of their feed water should have it analysed at some chemical laboratory and ascertain the best treatment in the particular circumstances.Special attention is drawn to the not infrequent very bad practice of allowing the waste steam from the engine cylinders or pumps to be drained into the boiler feed water tanks. The waste steam from cylinders is always run with a certain amount of oil matter which will be deposited in the feed water tanks and ultimately be pumped into the boiler with possible disastrous results as it will be obvious to every careful boiler attendant that should the oil be deposited on the furnace crowns. They may become overheated and collapse.It should be the first care of the boiler owner and the boiler attendant to see that the feed water is kept as pure as possible. Impure feed water means additional expense on the up keep of the boiler.Preservation of boilers when not in use. - Steam boilers when not in use are liable to deterioration from corrosion and unless well cared for, and made rust-proof they may depreciate more rapidly than when in use. They should be thoroughly drained and thoroughly dried and all valves, cock and openings closed so as to exclude moisture. Another plan is to fill the boiler with water to which about 1/10 per cent caustic soda has been added.Special instruction for Boiler No..........The boiler should be opened up and thoroughly cleaned after a period of work which should not exceed....................A record of such cleanings should be maintained and produced, when required by the inspector.Dated.............Inspector of BoilersForm 'D'Accident Report under Section 18(1) of the Indian Boilers Act, 1923ToThe Chief Inspector of Boilers,Rajasthan, JaipurThe undersigned begs to report that an accident occurred in the....................
