芒来煤矿褐煤改性提质试验研究

利用带式炉改性提质工艺,脱除影响芒来褐煤热值的水和部分含氧官能团,使褐煤的发热量组分富集,热值提升,达到中高热值燃料煤(≥20.9 MJ/kg)指标。 Water and parts of oxygen-containing functional groups effecting heat value of Manglai lignite were removed by the way of modification and dewatering technology of belt furnace.This technology enrich the components of heat,improve the heat value,which accords with the index of high calorific value fuel coal(≥20.9 MJ/kg)
