Circulating fluidized bed boiler with a single drum, natural circulation, on the whole is divided into two shafts front and rear. Total lifting the front of the shaft structure, surrounded by a membrane wall components. Bottom-up, followed by the primary air chamber, dense phase, dilute phase, followed by a top-down rear flue superheater, low temperature superheater and economizer, air preheater.

Using the tail shaft support structure between the two shafts are connected by a vertical cyclone through the lower part of the separator joins the loopback device and ash cooler. Internal combustion chamber and separator has a wear lining the front of the shaft furnace wall with light from eight steel columns bear the full weight of the boiler furnace wall tubes with Ao, external metal shield, tail shaft.

High efficiency CFB boiler for sale

Combustion efficiency can be maintained over 98-99%. High-temperature separator inlet flue gas temperature at about 800 ℃, smaller diameter cyclone to simplify the structure

1, high combustion efficiency and thermal efficiency.

2, by adding limestone, can be furnace desulfurization. Desulfurization rate of more than 90%, the use of low-temperature combustion and staged combustion, reducing the amount of harmful gases generated NOx, are environmentally friendly.

3, coal adaptability widely.

4, in favor of ash utilization in order to improve economic efficiency.
