China Dunhuang International Hotel relevant responsible person said, party fast or aftermarket both in pre-sales, remained consistent patient service, we have solved many difficult problems, with fast factory direct sale water tube boilers, we are assured. --customer feedback

Air scaling coefficient α (not on predetermined criteria)? A: According to GB / T16157-1996 "emissions from stationary sources of particulate matter and gaseous pollutants measured sampling methods", SO2 emission concentration of factory direct sale water tube boilers should be converted into the measured excess air coefficient α = 1.8 at a concentration of emission.

In summary, the difference between the atmospheric pressure hot water factory direct sale water tube boilers and hot water boiler mainly in furnace pressure changes, whether the water level under control and whether there are structural limitations in three areas. In fact, the difference between the two is far more than that, they are there is a difference in terms of service life, water supply, safety performance, if you carefully study will certainly find many differences, but the most important is to combine their own needs to consider, select which type of boiler products.

Mechanical incomplete combustion heat loss Q4The main factors that affect the heat loss of mechanical incomplete combustion are combustion mode, fuel property, furnace scaling, factory direct sale water tube boilers load, operation condition, operation level and so on. For chamber combustion furnace, due to the large proportion of fly ash to the total ash content of fuel, the incomplete combustion heat loss of fly ash occupies the main part, while the incomplete combustion heat loss of fly ash in cyclone furnace is smaller. The less ash in the fuel, the more volatile it is, and the finer the pulverized coal is, the smaller Q4 is. The reasonable arrangement of furnace scaling and burner can make pulverized coal have sufficient residence time and good aerodynamic condition in the furnace, the boiler load and operation condition are stable, the operator can carry on the correct operation regulation, and keep the proper excess air coefficient. When the flame center is correctly positioned and filled with the entire furnace, the mechanical incomplete combustion loss is minimal.
