Abstract

A direct injection proposal of ammonia hydroxide employed in Flue Gas SCR De-NOx process was presented and a simulation was implemented by the advanced CFD software Star-CCM to verify the performance of this proposal. The initial equipment investment cost and opAs an increasing number of power plants are engaged in grid peaking operations, the utility boiler working condition varies frequently and violently, which demands a more flexible and accurate control system. In present investigation, a model measuring heat storage capacity in steam and metal with operating data of 1000MW unit is proposed. In the scope of investigation, calculated result shows the overall heat coefficient in subcritical working condition is 27% more than that in supercritical condition. The heat storage coefficient distribution of steam and metal varies with the change of working condition, and detailed information is exhibited. Moreover, reheat steam system is also in the scope of present investigation which is rarely reported.eration cost could be reduced greatly by employing this proposal which will lead to one of important development directions in flue gas De-NOx.
