containing chamber 8, boiler body 1 are provided with the delivery port 7 and water return outlet that are communicated with water containing chamber 8, recovery port is communicated with main water pipeline 9, be provided with exhaust opening 6 above boiler body 1, exhaust opening 6 connects smoke discharging pipe 22, and the bottom of boiler body 1 is provided with burner 5, the side of described boiler body 1 is provided with the Pressure gauge 23 be communicated with water containing chamber 8, boiler body 1 bottom sides is provided with the air blast 3 and sewage draining exit 4 that are connected with its pipeline, water return outlet place is provided with filter, sewage draining exit mainly discharges the dirt be deposited on bottom water containing chamber, filter filters the water entering water containing chamber, prevents the water-pipe blockage in water containing chamber or flue, described flue 24 inside is provided with the water pipe 2 be connected with water containing chamber 8, water pipe is many curved pipes, water pipe arranges many rows before and after flue 24, thus increase the area of heat exchange, improve heat utilization ratio, boiler body 1 outer end is provided with thermal insulation layer, reduces the heat exchange of boiler body and extraneous air, improves heat utilization ratio, when boiler works, delivery port 7 and water return outlet and external pipe are connected, and are realized the circulation of current by circulating pump, first burner 5 is opened, the heat that burner 5 produces is transmitted by water pipe 2 and flue 24, and realizes heat exchange between current, finally heat is passed to outside, described smoke discharging pipe 22 enters from one end of deduster 12, then smoke discharging pipe 22 passes from the other end of deduster 12, flue gas in smoke discharging pipe 22 carries out preliminary dust removal process through deduster 12, then stretch out from heat exchange case 17 after smoke
