Energy-saving heating equipment based on surface combustion technology

The utility model discloses energy-saving heating equipment based on the surface combustion technology, and belongs to the technical field of energy-saving heating equipment. Comprising the steps that a combustor is arranged in the energy-saving heating equipment, and a plurality of annular heat exchange pipes are sequentially arranged on the outer side of the combustor from inside to outside; gas premixed gas enters the energy-saving heating equipment through the gas inlet to be combusted with the combustor, uniform heat flow is released during combustion and exchanges heat with heat exchange media in the annular heat exchange pipes, and heat received by the annular heat exchange pipes is sequentially decreased from inside to outside. The surface flameless combustor is adopted to directly combust premixed gas, the effects of reducing pollutant emission and noise pollution are achieved, meanwhile, uniform and short flames are generated on the outer side of the combustor through the surface combustion technolo
