蒸汽机车烧用块煤,其效能远比烧混末煤、原煤优越。它可大幅度提高机车的锅炉效率、供汽率、过热蒸汽温度,减少机械、化学不完全燃烧热损失,改善对环境的污染,充分发挥机车的牵引能力,多拉快跑,节约煤炭,有显著的经济效益。块煤的确是机车的对路燃料。一、试验概况为获得前进型机车由圆烟筒改用扁烟筒时,燃用不同煤种(型煤、块煤、混末煤)
Steam coal burning lump coal, its efficiency is far less than the end of burning mixed coal, superior coal. It can greatly improve the locomotive’s boiler efficiency, steam supply rate, superheated steam temperature, reduce mechanical, chemical incomplete combustion heat loss, improve the environmental pollution, give full play to traction locomotive capacity, Dora run, save coal, there Significant economic benefits. Lump coal is indeed the locomotive fuel on the road. First, the test profile In order to obtain forward-type locomotive from the round pipe to the flat pipe, the burning of different coal (briquette, lump coal, mixed coal)
