CFB boiler

300～660MW class supercritical (ultra-supercritical) circulating fluidized bed boiler

Boiler is an important equipment in the national economy. The electric power, machinery, metallurgy, chemical industry, textile, paper making, and industrial and civil heating all need the boiler to supply a large amount of steam.

The boiler is a supercritical parameter direct-flow furnace with circulating fluidized bed combustion, primary intermediate reheating, balanced ventilation, and a full steel frame structure. It features an M-type layout with water-cooled walls and screens in series, a steam-cooled cyclone separator, dual "N" -shaped returners, no external bed, dual flue at the rear, baffle temperature control, combined front and rear wall coal feeding, and bottom slag discharge. The boiler delivers excellent performance and stable operation.

technological superiority ：

(1) Hydrodynamic safety and reliability;

(2) The boiler has high efficiency and low cost for achieving ultra-low emissions;

(3) Uniform wall temperature and bed temperature;

(4) The furnace screen shows no deformation or wear, and the air cap prevents slag leakage.

(5) It can achieve large-scale co-firing of inferior fuels such as coal slime and coal gangue.
