For achieving the above object, the utility model provides following technical scheme: a kind of many return stroke halfs gasification low-carbon combustion energy-saving environmental protection boiler, comprises base, deashing device, combustion zone, coal preheating zone, high-temperature flue gas assimilate district, gasification, and combustion district and support; Described deashing device is fixed on base; Described combustion zone and gasification combustion zone are arranged on the right-hand member and left end that support internal cavity, and combustion zone is positioned at the positive upper end of deashing device; Described high-temperature flue gas is assimilated district and is arranged on coal preheating zone and gasification upper end, combustion zone.
Further, side, described support bottom is connected with outlet pipe and return pipe up and down, and outlet pipe connection high-temperature flue gas assimilates district.
Further, described gasification, and combustion district is provided with tune wind oxygen supply door.
Further, described high-temperature flue gas is assimilated side, district and is provided with the first shoot door, and described deashing device side is provided with the second shoot door.
Further, described high-temperature flue gas is assimilated in district and is connected with chimney.
Further, described high-temperature flue gas assimilates district for horizontal many backhauls and the uniform absorbing structure of shunting.
Compared with prior art, the beneficial effects of the utility model are: one adopts semi-coal gas overheavy firing technology and many backhauls automatic ash removing technology can reduce machinery not combustible loss and the heat loss due to exhaust gas of boiler, improve the thermal efficiency of boiler, reach the level that energy conservation standard requires, bring significant energy-saving effect; Take controllable air quantity during two boiler combustions, reach overheavy firing effect with low coefficient of excess air, be conducive to the discharge reducing NOs, adopt Semi-gas burning simultaneously, the dustiness of boiler export flue gas can be reduced, can atmosphere pollution be effectively reduced; Three boiler structures break through the form of existing normal-pressure hot-water boiler, consider the feature of burning and the flow process of water and the flue gas flow of many backhauls fully, adopt overheavy firing technology, form the normal-pressure boiler version having effects of energy saving and emission reduction shown in sketch.Overall structure is simple, practical, is easy to promote the use of.
