power plant boiler for paper mill
There are many business units to be able to save more spending often treated power plant boiler for paper mill water will take unscientific methods and tools in boiler water treatment process used, equipment, etc. also do not comply with the relevant provisions, For example, "three noes" of electronic instruments and antifouling agent scale.
Hot water power plant boiler for paper mill is one of the important equipment for the district to provide our real estate company, and two gas hot water provide the fast boiler boiler flotilla of environmental performance, in full compliance with state regulations after smoke was detected in the rear of the boiler. And boiler operation is safe, stable, we use the very at ease. --customer feedback
heat loss due to exhaust gas
Of all the heat losses in a chamber furnace, the heat loss from exhaust smoke was the largest, at about 4% and 8%. The main factors affecting the size of Q2 are exhaust volume and exhaust temperature. Exhaust volume is large, exhaust temperature is high, exhaust heat loss is large. In general, Q _ 2 increases by about 1% when the exhaust temperature is increased by 10 ℃ and 15 ℃. Reduce the exhaust temperature, can reduce the heat loss of exhaust smoke. But it is unreasonable and impermissible to lower the exhaust temperature. In order to reduce the exhaust temperature, the heating area at the end of the boiler will be increased, which not only increases the steel consumption, but also increases the flow resistance on the exhaust side, so it is necessary to consume more energy in operation. In addition, the exhaust temperature should be kept higher in order to reduce the low temperature corrosion of the tail heated surface, especially when the fuel with high sulfur content is used. Therefore, reasonable exhaust temperature should be determined by technical and economic comparison. For modern large and medium-sized boilers, the exhaust gas temperature is usually 110 ℃ 160 ℃.
3, premix combustion system
Combustion efficiency depends on the mixing ratio of gas and air and a combustor quality, variable frequency fan condensing boiler technology, according to the load demand, the flexible adjustment of the air amount; while adjusting the amount of gas condensing boiler technology adjusted by precise proportions, both remain at the most good mixing ratio, to ensure complete combustion. Unique water-cooled burners, the flame temperature is rapidly lowered, improve the combustion efficiency while ensuring low emissions of harmful substances.
