power plant boiler

Circulation fluid bed boiler to belong to the low temperature combustion, simultaneously in the stove fine burns through the condition to cause boilers ash dregs carbon amount to below, belongs to the low temperature to burn thoroughly, easy to realize the comprehensive utilization.

The circulation fluid bed boiler joins the limestone in the stove, may carry on the simple desulphurization in the stove, when a calcium sulfur mole of ratio is 2, the desulphurization efficiency may achieve above 80%; Because the movement wins a prize the graduation blast generation of road warm combustion, therefore the NOx production quantity is extremely low, Therefore reduces sox and the NOx withdrawal greatly, the improvement atmosphere and the environment quality.

Operation will present the load change frequently, when will shoulder will fall to 70% below, other type boiler combustion efficiency and the thermal efficiency will obviously reduce, and will burn is very unstable, sometimes even cannot maintain the normal combustion; But circulates the fluid bed boiler only to adjust to the coal amount, the air volume and the counter-material circulation, therefore other loads may adjust between 30-110%; In addition because the section wind speed is high and the heat absorption control is easy, to circulate the fluid bed boiler load control speed to be also very quick, generally may reach each minute 4%.

In circulates in the fluid bed boiler, the fuel only occupies the bed material about 3%, other are not the inflammable solid particles. The circulation fluid bed boiler special hydrodynamics characteristic causes to be mad that solid and the solid mix is firmly good, therefore after the fuel enters the chamber, very quick and the massive bed material mix, the fuel is heated up rapidly to the flame temperature, but with enters the bed temperature not to reduce obviously. Therefore all coals plant may in stable highly effective combustion. In the movement transforms when the coal plants, the fuel-burning equipment and the boiler proper does not make any revision also to be possible to obtain .

 Features and specifications:

The combustion efficiency high circulation fluid bed boiler lies in the combustion system with the other type boilers basic difference. The circulation fluid bed boilers combustion system is by combustion chamber, the material collector and the counter-glassware is composed. Under the high temperature material in the air current smuggles enters the material collector, the material which collects is entered the counter-glassware, passes through the counter-glassware back combustion chamber again, carries on circulates many times the combustion, therefore the combustion efficiency is very high.
