Methods brewery steam chain grate boiler efficiency corrosion which either the boiler, after a long period of use, the boiler will occur in many chemical reactions, and according to the water quality of boiler employed, the chemical reaction in the boiler will be different. Various chemicals in the long term to withstand high temperatures, high humidity conditions likely to occur in many chemical reactions. Brewery steam boiler maintenance, especially after the shutdown, the shutdown cooling the first thing to note, the heated area ash must be thoroughly cleaned, a lower furnace and an upper grate ash, in order to maintain a certain degree of natural. Ventilation ducts ventilation. In general, in order to prevent furnace body moisture, the desiccant should be placed in the furnace and the flue. If quicklime is used as a desiccant, should be placed 3kg per cubic meter of flue or furnace. After placing all the ventilation doors should be closed tightly. After lime powder should be replaced with low-lying location of the boiler room, the ground should be serious flooding during the work stoppage, it should be combined with the frequent low fire to dry and placed desiccant. To remind you that now more than boiler water treatment method, technically more mature, before the water can be injected into the boiler, boiler corrosion maintenance is very important to note.
Gas hot water boiler and heating water for people living essential energy equipment, because of its specificity performance of the need to comply with strict safety operation of the Code. Then, gas hot water boiler needs to run how to protect their safety performance?
1, after carefully checking gas hot water boiler water supply, drainage, gas pipe fittings, safety valve, pressure gauge, water level gauge is sensitive Haoshi before work, make sure it is safe to operate.
2, with both hands to manipulate when Sheung hand to open the door of water, whereupon the other hand the water injector and valve open, water flows naturally into the furnace. When stopped, the steam valve should be closed first, then turn off the water door, switch and valve, the front face must escape in order to avoid accidents caused by soft drinks out.
3, gas hot water boiler in operation, to pay attention to all parts of the check, and observe whether the water pressure in the normal range. Fireman can not leave their posts without permission, when night work, avoid dozing off, but not allowed to sleep, to avoid accidents. Boiler blowdown, a class must be properly adjusted before the sewage water level, slightly higher than the normal water level of 2/3 of the standard, then the sewage.
4, the water level table class must be flushed once. Flushing, according to a predetermined program, the first closing valve and open the drain valve, flushing steam valve, when attention is blocked steam origin; steam valve is then closed, when attention is blocked antecedents water. Flushing valve, until the water becomes steam, some a little longer, in order to guarantee no false water level. Hot water boiler fuel gas safety checks must be carried out to prevent the presence of explosive materials in the fuel to prevent the risk of explosion.
