In this paper, the thermal calculation is been done based on the 75t/h medium-pressure gas boiler which combines the natural gas, BFG and LDG in the electricity station supplied by some company utilizing the boiler balance calculation and alo anti-balance calculation supplement method. And it analyzes the factors to influence the thermal efficiency of gas boiler and caculates the the temputure of emission smoke and the proportion of heat loss according to the characteristics of gas boiler and the boiler thermal parameter tested in the site; Through analysis the surplus air confieient in the exit of exellent operations, this paper pays attention to offer the reasonable amount of wind, saving energy, reducing emission and heat loss and to improve the burning effiency of boiler by the technologies, equipments and skills.
