摘要

研究了农业生物质型煤(黑麦秸秆、芒草、干草、玉米秸秆)在25kw原木气化锅炉上的两段燃烧。所选燃料负荷和生物质类型的以下相关性显示:气化室和燃烧区温度随时间的波动，一氧化碳和一氧化氮浓度随时间的变化，烟气中一氧化氮和一氧化碳浓度之间的相关性，以及一氧化碳和一氧化氮浓度随燃烧区氧气浓度和温度的变化。农业生物质的两段燃烧被证明是有效的，因为不产生渣。烟气中相对较高的一氧化碳浓度是由于气化室和燃烧区的空气供应缺乏自动调节造成的。

Carbon monoxide and nitric oxide concentrations in the flue gas during the combustion of agricultural biomass briquettes in a 25 kW log gasification boiler

A study was made of the two-stage combustion of agricultural biomass briquettes (rye straw, miscanthus, hay, corn stover) in a 25 kW wood log gasification boiler. The following correlations for selected fuel loads and biomass types were shown: fluctuation of temperature over time both in the gasification chamber and in the combustion zone, variation over time of carbon monoxide and nitric oxide concentrations, correlation between nitric oxide and carbon monoxide concentrations in the flue gas, and variation of carbon monoxide and nitric oxide concentrations versus oxygen concentration and temperature in the combustion zone. Two-stage combustion of agricultural biomass proved to be efficient, as slag was not generated. Relatively high carbon monoxide concentrations in the flue gas resulted from the lack of automated regulation of air supply to the gasification chamber and the combustion zone.
