二是降低烟尘初始排放量和烟气黑度。
这些参数包括烟气的平均辐射长度、烟气黑度、对流传热系数、烟气的热焓等。
The parameters considered include the mean beam length of flue gas, the emissivity of gas, the film beat transfer coefficient and the enthalpy of flue gas.
并且因为在炉排上的燃烧是半焦化的煤焦，因此产生的飞灰量小，烟尘浓度、烟气黑度都比较低。
And because in the combustion is half stoker, resulting capital of coking of fly ash, the small amount of smoke concentration and blackness is low.
本标准分年限规定了锅炉烟气中烟尘、二氧化硫和氮氧化物的最高允许排放浓度和烟气黑度的排放限值。
This Standard specifies the supreme permissible effluent concentration of flue dust, SO2 and nitrogen oxides as well as the emission limits of flue gas blackness by age limits.
