PRODUCT DESCRIPTION


The new type double cyclone circulating fluidized bed boiler with low speed is a new generation, which is designed by Tsinghua University: Zhengzhou Research Institution of Low Speed Circulating Fluidized Bed Boiler. The boiler inherits the original technology advantages, at the same time, makes big breakthrough on the technology of cyclone design on combustion, cyclone separator structure & parametric design, and loop seal system. The boiler is awarded as national patent product.

APPLICATION


Zhongding new type double cyclone circulating fluidized bed boiler is a high efficiency, energy saving and environmental protect equipment. It is generally used in power station, central heating, city heating, paper plant, etc.
 

FEATURES


Technical Breakthrough




Technical Continuity


1. Compact structure

Integrate furnace, separator and loop seal system by using membrane water wall, structure compact.


2. Low thermal loss

The loop seal system is composed of two membrane water walls, and the partial heat carried by the fly ash is absorbed by the water wall tube.


3. Adopts anti wear design

A number of measures used on anti wear design, reduce the fluidization velocity, prevent the wear of separator heating surface and membrane water wall.


4. Various kinds of coal are adaptable.


5. The fault rate is extremely low


6. Environmental protection

low-temperature combustion technology, reduce the generation of noxious gas, the limestone can be added to the furnace for desulfuration, harmful gas emissions can meet the environment requirement without use of any denitrification equipment.
