Coal-fired boiler planning type, coal combustion boiler according to common can be divided into ignition and combustion methods such as suspension layer YQW-500Q oil furnace, boiler Correspondingly fixed or moving grate grate boiler boiler (hand burning stove), Stoker, reciprocating grate boilers and furnaces pleasure, circulating fluidized bed boilers; can be divided according to the way packaged boiler equipment, assembly and bulk boiler boiler; various boiler can purchase arrives heat efficiency is not the same YQW-2400Q oil furnace, its steel consumption is not the same, the device is not the same cycle length, the same as the nominal amount of evaporation boiler equipment required size is not the same place, on the coals adaptability not the same, the difference is larger offer; consideration should be summarized according to the most economical use of local coal, production needs, equipment, premises, using capital and other purchase. Coal-fired boiler thermal efficiency, thermal efficiency is the most direct impact on the use of capital parameters boiler, the higher thermal efficiency, the better; the manufacturers for their own boilers good, usually exaggerate the boiler thermal efficiency YQW-9300Q oil furnace, but the practice of thermal efficiency is usually reached less. , Coal oil furnace maintenance ① dry oil furnace maintenance of law, that is to go after the boiler shutdown put the pot of water, the net addition to the internal dirt thoroughly, rinse. If not used for long oil furnace, you can use low heat drying in the furnace, add lime, and then all wells, pipeline valves closed, inspected once every three months, such as lime crumbled into powder, that is to be replaced boiler rerun should be lime and disk removed. ② wet maintenance method, that after the oil furnace shutdown of the boiler water to be cooled to below 70 ℃ water exhausted the oven, will completely remove the dirt inside, rinse. Then all the manholes, hand holes, pipe valves and other closed tight, and with blind plate and run the boiler completely isolated. Maintenance period regularly Microflame oven regularly so that the water cycle, so that the concentration of alkaline solution is consistent throughout. Xiao Bian Tip: cold climate where maintenance of law can not be wet, so as not to damage the boiler furnace water freezing YQW-500Q oil furnace, boiler Arts (certified), oil furnace boiler by Hebei Arts LLC.
