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.

Product introductionProduct introduction

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
