充分利用低热值燃料,是解决我国煤炭供应紧张状况的重要课题之一。本文对往复炉排配蒸汽二次风燃低热值煤的试验情况作了详细介绍。试验情况表明,往复炉排配蒸汽二次风有良好的燃料适应性。它不但能适应热值大于3000大卡/公斤的Ⅰ类烟煤,而且对于2700～3000大卡/公斤的Ⅰ类烟煤及热值2500～2700大卡/公斤的高挥发份劣质煤亦能很好地适应。它同时还具有良好的经济性。
Making full use of low calorific value fuels is one of the important topics to solve the tight supply of coal in our country. In this paper, the reciprocating grate with steam secondary air burning low calorific value coal test conditions were described in detail. Test results show that reciprocating grate with steam secondary air has good fuel adaptability. It can not only adapt to Class Ⅰ bituminous coal with a calorific value greater than 3000 kcal / kg, but also class I bituminous coal with a capacity of 2700-3000 kcal / kg and high volatile low quality coal with a heat value of 2500-2700 kcal / kg Adapt to. It also has good economy at the same time.
