A low volatile bituminous coal was used as reburn fuel. 利用一种低挥发分烟煤作为再燃燃料,在煤粉携带炉中进行了该种煤再燃还原NO的实验研究。
In the experiments were used three pulverized coals and its chars and bituminous char with appended catalysts as reburning fuel. 实验中选用的再燃燃料为小龙潭褐煤、富拉尔基褐煤和大同烟煤及其煤焦,以及添加不同催化剂的大同烟煤焦。
The combustion process in a 300 MW tangentially fired boiler furnace employing inferior bituminous coal and anthracite as fuel, injected at different floor levels, has been simulated in two ways. 模拟了劣质烟煤和无烟煤在1台300MW四角切圆锅炉炉内分层混合燃烧的过程。
In this paper two kinds of lignite and bituminous coal, and their chars are selected as reburning fuel in the experiment to study the NO reduction in the reburning environment. 用两种褐煤和一种烟煤及其煤焦作为再燃燃料,实验研究了再燃环境下NO的还原。
Besides in the volatile matters the mass fraction of carbon oxides in bituminous coal is higher than anthracite. Bituminous coals are better as reburning fuel. 烟煤气态挥发分中碳氧化合物质量分数较高,可作为理想的再燃燃料。
In oxidizing atmosphere, as temperature increases, the bituminous char-N conversion increases. However, it has little influence on the anthracite char-N conversion. In reducing atmosphere, temperature increasing suppresses the fuel nitrogen conversion. 氧化性气氛下,温度的提高会促进烟煤焦炭燃料N的转化,而对无烟煤焦炭则基本无影响;还原性气氛下,温度的提高均会遏制燃料N的转化。
