CAUSE ANALYSIS OF HIGH EXHAUST GAS TEMPERATURE FROM HG-450/13.7-YM24 BOILER AND RETROFIT THEREOF
After putting HG-450/13.7-YM24 boiler of Guodian Suqian Thermal Power Co Ltd into operation
the actual exhaust gas temperature of said boiler was more far higher than the designed value.It is believed from analysis that the main cause resulting in high exhaust gas temperature from the boiler to be large flow rate of cooling air mixed into the coal pulverizing system
leading to deviation in designed heating surface.For this
a retrofitling scheme of additionally installing partial economizer and low-tempera- ture superheater to the said boiler has been put forward.After implementation
thermal parameters of the boiler has reached the de- signed values
