Sectional Axonometric Drawing

Energy-saving CFB boilers are researched and developed by the

fluidized reconstruction combustion technology of Zhengzhou Boiler

Co., Ltd., representing the latest direction of CFB technology

development. It has directly overcome the two problems of normal

CFB boilers, i.e. high electricity consumption and abrasion, thus the

electricity consumption can be reduced by at least 30%. Meanwhile,

it effectively makes up many shortcomings, such as boiler abrasion,

coking and blocking of back feeding device, high density of boiler

original dust emission, difficulty in slagging, etc., making the boiler

structure more reasonable, the performance better, and the

operation safer and more reliable. In December 2015, our energy-

saving CFB boiler is listed as the NO. 1 among high efficient boilers

in the “Energy Efficient Boilers Promotion Directory”, published by

National Development and Reform Commission.

Capacity: 35 - 410 t/h /29～168MWDesign thermal efficiency: 86 - 93%Applicable fuel: Various types of coal, co-firing and biomass fuel

Application: �Thermal power plant, central heating, steam and hot water supply

a. Bell-covered style of air cap, with low resistance and anti-back flow ash, has

completely settled the problem caused by backflow ash from air cap,

guaranteeing the combustion efficiency of the boiler.

b. Fuel particles could be burned in circulation. The combustion efficiency can be

as high as 97%-99%, and the boiler heat efficiency can be 85%.

High combustion efficiency1

The bed temperature of CFB boiler is between 800-900° C, which is the highest

temperature range for the desulfurization reaction efficiency.Due to the lower combustion temperature, the use of staged air supply makes

SO2 and NOx emissions from coal-fired circulating fluidized bed boilers are lower.

Low pollution emissions2

Low pressure operation, low flow speed of flue gas, low density of materials in the

furnace, hardly abrasive heating surface, low frequency of maintenance, all of the

above make the annual operating time longer than 8000 hours.

Low wear and high availability3
