CONTROLLER FOR INJECTION AMOUNT OF AMMONIA GAS IN DENITRATING APPARATUS FOR FLUE GAS

摘要

PURPOSE:To maintain a high efficiency of denitration and to decrease the loss of NH3, by equpping the same number of the programme signal generators synchronizing to the fluctuation pattern of operation state of the furnaces as the number of the furnaces and by setting the injection amount of NH3 gas by adding the output signals from the above generators.
