| titleOfInvention | Control device for amount of ammonia addition in denitration of coke oven waste gas |
| abstract | PURPOSE: To remove NO x efficiently and economically and reduce unreacted ammonia by controlling the amount of ammonia addition according to the fluctuations in the NO x concn. in waste gas in a catalytic reduction denitration method for coke over waste gas. n CONSTITUTION: In the catalytic reduction denitration of coke oven waste gas, the total amount of NO x s in the waste gas entering the catalyst bed of a reaction tower 1 is determined from flow rate and an analyzer 12, and the amount of ammonia corresponding to this is calculated with a rate setter 14. A control valve 24 is moved by the deviation between this signal and the actual flow rate of ammonia. Whereas, coke oven undergoes alteration periodically, and causes a sharp decrease particulrly in the NO x concn. and therefore at such a time, a timer 26 operates to cut off between a controller 23 and the valve 24, thereby stopping the supply of ammonia. In this way, denitration is accomplished efficiently, and even more, the oversupply of ammonia is eliminated and secondary pollution is prevented. n COPYRIGHT: (C)1981,JPO&Japio |
