A widely used chemical production of high performance environmentally friendly gas furnace, recently in the successful development of Hebei Province, Central Group Jizhou environmental protection and energy saving equipment factory and market. 
 The energy saving effect of the equipment, high thermal conversion efficiency, good environmental performance for a wide range, gas output up to 7000 m3 / gas calorific value of 5652 kJ / m, the fuel consumption of only 2000 kg / The sulfur dioxide content of emissions of soot per cubic meter of only 91 mg, significantly better than national standards. 
 According to reports, the device is innovative mainly in the secondary use of the device: one is through the development of flue gas recovery, allows air heat exchanger performance up to 200 ~ 400 ℃, can be significant savings in fuel, energy than similar products increased by 20% ; through the development of gas furnace air, water vapor ratio of new technology allows heat conversion rate increased by more than 5% higher than similar products; need different furnace burners, process transformation, so that the air gas mixed to achieve the best value and performance than similar products increased by 7%; four, better environmental performance through the transformation of the gas furnace internal structure. 
 At present, the plant has built a nearly 200 sets / year production line, and a variety of specifications.
