coke charge

Local and average heat transfer coefficients of coke bed in a coke dry quenching chamber;

干熄炉焦炭床层局部和平均换热系数

The coal fire retardant has abilities to promote the formation of carbonized layer and cut the reaction of free chain.

该阻燃添加剂具有促进形成焦化炭层和阻断自由基链式反应的功能,具有明显的阻燃、隔热、隔气、保水和优异的粘附煤体的特性。

The reason is that the residence time, the radial distributions of linear velocity and temperature of fluids in the reactor affect the thickness of coke layer greatly, they acts as controlling facfors of production.

其原因在于由管内流速引起的停留时间分布及径向温度分布影响了焦层厚度，对生产起制约作用。
