Brief Introduction:
DHL series corner tube chain grate boiler adopts GEF program's technology. Based on the domestic and foreign technical research, according to the technical development characteristics and market demand of chain grate, we carried out independent innovative design so as to produce the high-capacity energy-saving chain grate boilers with advantages of reliable water cycling, efficient burning and low pollution.
Application:
Central heating supply, heat supply in winter, industrial steam and hot water supply.
1.Adopting two patents: the flying dust internal cycling fluidized re-combustion device based on the high temperature separation technology; the combined design of equal flow speed for the flag type convection heating surface of corner tube boilers.
2.Adopting crossgirder grate, with less running resistance, better grate cooling effect, lower breakdown rate and less fuel leakage.
3.Light supporting wall structure which has the advantages of better insulation ability, no dust leakage and environment friendly. Besides, the boiler adopts technologies like secondary air turbulent flowing pattern, fly ash separation based on high temperature and fly ash internal cycling fluidized re-combustion.
