Industrial condensing hot water boilers body for the shell type all wet back downflow three return pyrotechnic tube structure, the flame in the large combustion chamber micro positive pressure combustion. Low combustion heat load, less emissions of harmful substances NOx. The series of hot water boilers have been tested and verified by the advanced test bed of the whole machine for many times, so that the boilers can get good thermal performance, qualified flue gas emission index and a wide range of burner adaption under various loads.
The smoke boxes before and after industrial gas hot water boilers are made of special heat preservation and insulation materials, which have the advantages of high temperature resistance, low thermal conductivity and good ability to resist rapid cooling and thermal energy, greatly prolongs the service life of the smoke boxes. The lower part of the smoke box is provided with condensate water outlet to reduce the corrosion of the condensate water to the pressure parts. The boiler device and each pipe orifice layout is reasonable, optimize the water circulation in the boiler, effectively prevent scale generation, but also to improve the water side heat transfer effect. Set hand holes and inspection holes in weak links with poor circulation to facilitate regular inspection and maintenance.
