混烧石油焦油页岩循环流化床灰渣特性的试验研究

在1 MW流化床(CFB)燃烧试验台试烧5种不同掺烧比例的石油焦和油页岩混合燃料.对燃烧产生的灰渣特性进行了分析研究.分析结果表明,石油焦和油页岩混合燃料试烧后形成的底渣和飞灰粒度与常规煤种相比趋于偏细；而且,随着混合燃料中油页岩掺烧比例的升高,对灰渣份额、燃烧效率、飞灰比电阻值、飞灰磨损特性等都有明显的影响.在钙硫比...

Experimental Study of the Ash and Slag Characteristics of a Circulating Fluidized Bed Burning a Mixture of Oil Coke and Shale

On a 1 MW circulating fluidized bed combustion test rig,a fuel mixture of oil coke and shale in five mixing and dilution proportions was tried and burned with the characteristics of ash and slag produced during the combustion being analyzed and studied.The analytic results show that the particle diameter of the bottom slag and flying ash formed by burning the fuel mixture of oil coke and shale tends to be excessively fine compared with that of the conventional coal ranks.Furthermore,with an increase of the ...
