Product Description
Introduction
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
Advantage
1. Technological breakthrough
The new type boiler has great technological breakthrough on cyclone separator structure design, separator’s parametrization design, loop seal system, and cyclone design on combustion, effectively improve the combustion and separate efficiency, avoid the problem of coking.
2. Compact structure
Integrate furnace, separator and loop seal system by using membrane water wall, structure compact.
3. 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.
4. 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.
5. Various kinds of coal are adaptable.
6. The fault rate is extremely low
7. 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 .
