一、对SHL20-13-W锅炉的评价北京锅炉厂产SHL20-13-W锅炉,设计采用燃料为无烟煤,低位发热值与挥发分分别为27100.16kJ/kg和5.49％,设计热效率为77.5％。该炉试运时,我们采用发热值为17581.2kJ/kg,挥发分为30％的烟煤试烧,当蒸汽出力达到20t/h,热效率68％时,炉渣含炭量较高,为18％～22％,与同吨位的烟煤链条炉基本相似,但蒸汽出力则优于其它型号的锅炉。当改烧14651～15906.8kJ/kg的烟煤时,产汽量稍有下降,但仍获得较好的效果,经分析如下。
First, the evaluation of SHL20-13-W boiler Beijing Boiler SHL20-13-W boiler production, the design of the fuel for anthracite, low calorific value and volatile were 27100.16kJ / kg and 5.49%, the design thermal efficiency of 77.5%. During commissioning of the furnace, we use the test of bituminous coal with calorific value of 17581.2kJ / kg and 30% volatilization, and when the steam output reaches 20t / h and the thermal efficiency is 68%, the carbon content of the slag is high, which is 18% 22%, which is basically similar to the bituminous chain furnace with the same tonnage, but the steam output is superior to other types of boilers. When burning 14651 ~ 15906.8kJ / kg of bituminous coal, the gas production slightly decreased, but still get better results, the following analysis.
