Measurement of a gas-fired boiler flue gas condensate heat and water deep recycle and denitrification integration project

To solve the problems of high flue gas exhaust temperature, high nitrogen oxide content in flue gas and serious fog emissions in a gas-fired heating boiler room in Beijing, adopting the anti-corrosion high-efficient flue gas condensate heat and water recovery technology combined with catalytic oxidation denitrification technology, performs the reformation for the heating boiler and the field measurement. The results show that the temperature of exhaust gas can be reduced to 25~45 ℃, the efficiency of gas utilization can be increased by 6.7%~18%, and the system can recycle 10.3~28.8 t/d flue gas condensate water and decrease 43%~54% nitrogen oxide exhaust.
