尿素水解制氨技术在百万燃煤机组上的应用

Application of Urea Hydrolysis to Ammonia in One Million Coal-Fired Units

通过对某电厂两台百万机组处于高负荷工况下脱硝系统各参数的测试,比较氨蒸气流量折算纯氨流量与实测值计算理论喷氨流量得出:在高负荷工况下,1号机组两侧、2号机组A侧脱硝反应器实测值计算理论喷氨流量与氨蒸气流量折算纯氨流量的比值在0.90~1.13之间;2号机组B侧脱硝反应器实测值计算理论喷氨流量与氨蒸气流量折算纯氨流量的比值在1.24~1.32之间。

About two millions of units of A certain power plant in high load condition test,the parameters of denitration system comparing ammonia vapor flow reduced pure ammonia flow and measured values calculated theoretical spraying ammonia flow:under high load conditions,on both sides of unit 1 and unit 2 reactor has been A side measured flow calculation theory of spraying ammonia and ammonia vapor flow reduced pure ammonia flow ratio is between 0.90 to 1.13;The ratio of theoretical ammonia injection flow rate to ammonia vapor flow rate converted to pure ammonia flow rate is between 1.24 and 1.32.
