Study and application of automatic control device for the flue gas temperature of utility boilers;

It calculates the relation ship between thermal efficiency of natural gas and flue gas temperature which is shown as curves.

This method could forecast the rubber discharging temperature, discharging time and so on.

Causal analysis of high exhaust gas temperature for 300 MW boilers and countermeasures;

Analysis and treatment of high exhaust gas temperature for 135 MW boiler;

And the comprehensive influence of exhaust gas temperature and excess air ratio to the heat efficiency is analyzed quantitatively.

Experimental analysis of high waste-gas temperature of DG1000/170-1 boilers;

15, improving the combustion condition and convection and radiate heat transfer efficacy, resuling in reducing the waste-gas temperature 45?℃, decreasing exhaust gas loss, and saving fuel by 6?%.

The ideal operational value of waste-gas temperature is provided through combining the boiler s practical operation and the research of heat loss due to exhaust gas, which offers important theory and paves a solid way in optimizing boiler operation.
