Described burner hearth is divided into the first burner hearth precombustion chamber, the second burner hearth main combustion chamber and the 3rd burner hearth burning chamber; The first burner hearth precombustion chamber and the second burner hearth main combustion chamber are separated by water-cooled grate, the second burner hearth main combustion chamber and the 3rd burner hearth burning chamber are separated by furnace wall and leave the exhaust gases passes aditus laryngis, the second burner hearth main combustion chamber and lower air chamber are separated by lower fire grating, and dedusting grid hole pattern plate is housed in the 3rd burner hearth burning chamber.

Be provided with three groups of heat pipes in the described drum, three groups of heat pipes stretch in the steel pipe for preceding half section, and the second half section is stretched in the drum.

The utlity model has following advantage:

1, sectional combustion repeatedly changes a burner hearth of present conventional boiler into three burner hearths, in the first burner hearth precombustion chamber coal, air intake, pre-burning.At the second burner hearth main combustion chamber high-temp combustion, burn at the 3rd burner hearth, dedusting, smoke elimination, thereby produce high temperature more than 1300 ℃, fuel is burnt in burner hearth fully, both guaranteed smokeless environment-friendly, improved the efficiency of combustion of boiler again, saved the energy.

2, body of heater adopts the integral cast of high-alumina refractory heat-insulating material, and the black furnace that dewaters is exclusive not to be arranged and guaranteed the high-temp combustion of fuel under adiabatic condition by any heating surface, has reduced boiler and has leaked out, and has further improved the efficient of burning.

3, repeatedly segmentation heat absorption, the high-temperature flue gas first heat pipe heat high-temperature heat pipe group of flowing through successively, the second heat pipe heat moderate temperature heat pipe group, the 3rd heat pipe heat Cryo Heat Tube group, high-temperature flue gas is emitted heat rapidly under the effect of high-efficiency superconducting heat pipe, the exhaust gas temperature of boiler is reduced to below 150 ℃, greatly reduce the flue gas loss of boiler, improved boiler efficiency.

4, be provided with device for eliminating smoke and dust in the stove, be provided with dedusting grid hole pattern plate at three-barreled top, high-temperature flue gas is flowed through behind the dedusting grid hole pattern plate, has removed the flue dust that itself carries, and has realized the purpose of smokeless and dust free.

The utility model has been realized smokeless and dust free in operation, environment protecting is remarkable, has realized energy-efficiently, has broken through the present coal-burning boiler thermal efficiency that is beyond one's reach.

The specific embodiment

As shown in Figure 1 and Figure 2, the horizontal inverse burning hot pipe boiler of a kind of smoke-less power-saving, it comprises burner block, drum 11 air-introduced machines 12 and the chimney of being made up of burner hearth, air compartment 15, dedusting grid hole pattern plate 7 13 described boiler.Drum 11 is connected with burner block, is welded with steel pipe in the drum 11, is welded with heat pipe on the steel pipe; Air-introduced machine 12 is connected with drum 11 by heat pipe.Burner hearth is divided into the first burner hearth precombustion chamber 1, the second burner hearth main combustion chamber 2 and the 3rd burner hearth burning chamber 6; The first burner hearth precombustion chamber 1 and the second burner hearth main combustion chamber 3 are separated by water-cooled grate 2, the second burner hearth main combustion chamber 3 and the 3rd burner hearth burning chamber 6 are separated by furnace wall and leave exhaust gases passes aditus laryngis 5, the second burner hearth main combustion chamber 3 is separated by lower fire grating 4 with lower air chamber 15, and dedusting grid hole pattern plate 7 is housed in the 3rd burner hearth burning chamber 6.Be provided with the first heat pipe heat high-temperature heat pipe group 8, the second heat pipe heat moderate temperature heat pipe group 9, the 3rd heat pipe heat Cryo Heat Tube group 10 in the drum 11, three groups heat pipe stretches in the steel pipe that flue gas flows through for preceding half section, second half section is stretched in the medium (water and steam) of drum 11, carries out heat exchange with medium (water and steam) in the drum 11.Drive flue gas by air-introduced machine 12 and form anti-burning, and it is mobile to form three backhauls in three groups of heat pipe groups.

Coal-fired and air enters the first burner hearth precombustion chamber 1 from fire door 14 respectively, and fire coal begins heating, separates out fugitive constituent, pre-burning.Fire coal is separated out flame that the scorching hot coke that forms behind the fugitive constituent and spent fuel gas form and is passed water-cooled grate 2 and enter the second burner hearth main combustion chamber 3 and enter the high-temperature heat insulation burning, form high-temperature flue gas, and enter the 3rd burner hearth burning chamber 6 by aditus laryngis 5, carbon containing flying dust in the flue gas and not the fuel gas of burning-out in the 3rd burner hearth burning chamber, burn away, so far, under action of high temperature, almost all burning is clean for the composition that can burn in the fuel.High-temperature flue gas self carries out smoke abatement and dust control in the stove by the dedusting grid hole pattern plate 7 of three roof of the furnaces, enter the first heat pipe heat high-temperature heat pipe group 8, the second heat pipe heat moderate temperature heat pipe group 9, the 3rd heat pipe group Cryo Heat Tube group 10 then successively, rapidly the heat pipe of heat by efficient heat transfer passed to the medium (water and steam) in the drum 11, finished the high-temperature flue gas temperature at this moment of heat transfer mission and reduced to below 150 ℃, taken out toward chimney 13 rows to atmosphere by air-introduced machine 12.
