Technical field
The utility model relates to a kind of middle-size and small-size coal-fired steam boiler or coal-fired normal-pressure hot-water boiler.
Background technology
At present, known middle-size and small-size coal-fired steam boiler and normal-pressure hot-water boiler all inevitably produce very big black smoke and more dust when operation, environment is caused severe contamination, very harmful, and the thermal efficiency is low, and the overwhelming majority causes great waste all below 60% to energy resources.
Summary of the invention
For overcoming the low disadvantage that causes a large amount of energy resources wastes of existing middle-size and small-size coal-fired steam boiler and middle-size and small-size coal-fired hot-water boiler volume of smoke contaminated environment and the thermal efficiency, the utility model provides a kind of environment protecting good, keep smokeless operation during operation, and thermal efficiency height, compare the boiler of energy-conservation smoke-less power-saving more than 30% with present boiler.
Main technical schemes of the present utility model is as follows:
The horizontal inverse burning hot pipe boiler of a kind of smoke-less power-saving comprises burner block, drum, air-introduced machine and the chimney be made up of burner hearth, air compartment, dedusting grid hole pattern plate; Drum is connected with burner block, is welded with steel pipe in the drum, is welded with heat pipe on the steel pipe; Air-introduced machine is connected with drum by airduct.
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.
