DENITRATING METHOD FOR COKE OVEN EXHAUST GAS

摘要

PURPOSE:To make possible automatic control of NH3 feeding corresponding to the NOx generation in exhaust gas by measurement of wave forlm of change with passage of time in NOx generation in a given unit combustion period to make a standard pattern and by calculating change in peak of wave form in each subsequent unit combustion period as a value correlated with the standard pattern.
