The main technology of the drum dryer boiling furnace

The main technology of the drum dryer boiling furnace
1. Isobaric air chamber, two-stage combustion, U-shaped combustion section can be used to separate and collect unburned fine carbon particles, and extend the burn-out time;
2. The air distribution device with large pitch and variable hole hood has good fluidization quality and combustion technology to reduce the influence of uneven distribution caused by edge effect.
3, using a large excess air coefficient, strengthen the air agitation in the furnace, strengthen the combustion, so that the coal is fully burned in the furnace, the temperature is uniform, and the control is convenient;
4. Adopt reasonable suspension structure, the flow rate of flue gas is low, the amount of fine ash is small, and the high temperature of heating flue gas can reach 1050 °C.
