摘要:

针对低热值气体蓄热燃烧产生高温气体系统,研究低热值气体的系统贫燃极限、高温气体可达温度及影响因素规律.在搭建的大型低热值气体蓄热燃烧高温气体发生试验系统中,试验研究低热值气体浓度和产生的高温烟气温度、流量之间的关系,探讨启动能量和换向周期的影响.通过实验和能量平衡分析,结果表明,该系统的低热值气体系统贫燃极限接近200 kJ/m3;在系统中燃烧甲烷体积分数为1.2%的低热值气体可连续稳定产生温度高于1 000 ℃的高温烟气,系统热效率大于80%.

Abstract:

Lean flammability and generating gas temperature characteristics were investigated experimentally in a regenerative high temperature exhaust-gas generating system burning low heating-value gas. Studying relationships among the low heating-value gas concentration, generating gas temperature and its flow rate shows the generating gas temperature, flow and methaneconcentration in the mixing gasare mutual coupling.The generating gas temperature is inversely proportional to its flow ratio and proportional to the methaneconcentration.The effects of starting energy and switching period were also analysised. The experiment results and energy balance calculations show that the lean flammability of the system iwas about 200 kJ/m3. High temperature exhasust-gas exceeding 1 000 ℃may be stably generated from the regenerative combustion system while burning low heating-value gas, of which methane concentration is 1.2%. The thermal effiency of the system is higher than 80%.
