1. Primary air fan: after being heated by the air pre-heater, primary air enters into the wind chamber, then into the furnace through wind caps through the air distributor to fluidize particulate materials;2. Secondary air fan: after being heated by the air pre-heater, secondary air enters into the furnace through the secondary air ducts for complete combustion of fuels; the seal air, conveying air and fuel spreading air of the feeding device also adopt secondary air; 3. Circ...
1. Rational air distribution, supply sufficient and rational air by region; 2. Appropriate furnace temperature;3. Suitable air turbulence and mixing in furnace;4. Fuels remain long enough on chain grate and in the furnace;5. Keep a reasonable distance between the fuel hopper and the flame fronts to avoid igniting fuels in the hopper.The biomass-fired boilers are optimally designed according to the characteristics of different biomass fuels. ZOZEN will customize the biomass-fired boiler for ...
The bed temperature rises sharply.
Oxygen levels go down and sometimes drop to zero.
The electric current of primary air fan is less and wind pressure of air compartment is higher.
Negative pressure of furnace is increased while the electric current of induced draft fan is reduced.
The slag discharge is difficult or unsuccessful.
When appearing bed clinkering, the bed temperature and bed pressure will be uneven distributed and not at normal condition; the measuring point of part bed tempe...
