Technical field
The utility model belongs to worker's civil boiler product, be a kind of be the boiler plant of coal gasification and burning one in the stove of raw material, fixed grate with raw coal or industrial shaping coal.
Background technology
China be only in the world several be one of the country of main energy sources with coal, and will be China's energy main body in significant period of time from now on, it mainly utilizes form is direct burning, directly Coal-fired capacity takies more than 80% of coal total amount.At present, the most Industrial Boilers of China all can only adopt the directly diffusing burning mode of raw coal, cause serious dust pollution and energy waste.Increase along with consumption of coal, the coal direct combustion has become the main source of China's environmental contaminants discharging, become one of main restricting factor that influences economy and social development, research and develop a kind of environment-friendly high-efficiency coal-burning boiler, extremely urgent to alleviate to environment damage.The coal gasification is to be the technology of gas combustion (former) material under optimum conditions with coal conversion, compare with the direct burning of coal, the coal after-combustion of gasifying not only can be significantly reduced pollution to atmospheric environment, and can improve efficiency of combustion, be one of best clean coal technology.In view of the above, the gasification, and combustion coal-burning boiler comes out in the stove in recent years, but because the problem that in the boiler structure design, exists, its gasification efficient, combustion efficiency and heat exchanger effectiveness also have more deficiency, suddenly wait to improve and improve.
Summary of the invention
The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides a kind of pair of drum coal gasification combustion fixed grate boiler, by adopting raw coal (or moulded coal) is gasified in burner hearth and fully completing combustion, effectively carry out the structural design of heat exchange, solve the deficiency that coal-burning boiler is big for environment pollution, the thermal efficiency is low, reach the purpose that alleviates coal-burning boiler environmental pollution, energy savings, the raising thermal efficiency significantly.
Basic design of the present utility model is, this boiler comprises fire-resistant end liner, coal gasification burner hearth and the after-flame burner hearth secondary wind jet pipe of partition wall between base, after-flame burner hearth, coal gasification combustion burner hearth, two burner hearths and flame export, fixed grate, air compartment, after-flame burner hearth bottom and fits over the after-flame burner hearth admittedly and the upper drum of coal gasification combustion burner hearth top, equipped lower drum below upper drum, the two ends of last lower drum communicating pipe that are positioned at convection pass are affixed with upper and lower drum respectively, be communicated with; On the relative side wall of after-flame burner hearth, be respectively equipped with the fine ash that matches with flame export and after-flame burner hearth secondary wind jet pipe from chimney arch and high temperature smoke elimination chimney arch, the postmedian of its high temperature smoke elimination chimney arch cuts off after-flame burner hearth and after-flame flue, only is provided with the passage that the after-flame burner hearth is connected with the after-flame flue in the front portion of high temperature smoke elimination chimney arch; Above the after-flame burner hearth, be provided with the after-flame flue, the after-flame burner hearth is communicated with convection pass, so far constitute two drum coal gasification combustion fixed grate boilers.
The utility model set section energy environment-friendly boiler especially is fit to China's national situation, has boiler thermal output height, low, the flue gas water white transparency of initial dust-density emission, sufficient combustion, the characteristics that coal adaptability is strong, operating cost is cheap.

Piece number explanation among the figure:
1, fixed grate, 2, flame export, 3, convection pass, 4, fire-resistant end liner, 5, after-flame burner hearth, 6, fine ash be from chimney arch, 7, high temperature smoke elimination chimney arch, 8, coal gasification burner hearth secondary wind jet pipe, 9, after-flame burner hearth secondary wind jet pipe, 10, after-flame flue, 11, base, 12, lower drum, 13, air compartment, 14, coal gasification combustion burner hearth, 15, partition wall, and 16, upper drum, 17, go up lower drum communicating pipe.
The specific embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Two drum coal gasification combustion fixed grate boilers are included in to be provided with on the base 11 installs after-flame burner hearth 5 and coal gasification combustion burner hearth 14, be provided with partition wall 15 between two burner hearths 5 and 14, partition wall 15 middle parts have flame export 2, and after-flame burner hearth 5 and coal gasification combustion burner hearth 14 are communicated with; Fixed grate 1 is fitted in coal gasification combustion burner hearth 14 bottoms; Fixed grate 1 bottom is provided with air compartment 13; Fire-resistant end liner 4 is established and is contained in after-flame burner hearth 5 bottoms; Coal gasification burner hearth secondary wind jet pipe 8 and after-flame burner hearth secondary wind jet pipe 9 are arranged on the partition wall 15, and communicate with burner hearth 14 and 5 respectively; Upper drum 16 fits over after-flame burner hearth 5 and coal gasification combustion burner hearth 14 tops admittedly, equipped lower drum 12 below upper drum 16, and the two ends of last lower drum communicating pipes 17 that are positioned at convection pass 3 are affixed with upper and lower drum 16,12 respectively, and two drums 16 are communicated with 12.Be provided with after-flame flue 10 above after-flame burner hearth 5, this after-flame flue 10 is communicated with after-flame burner hearth 5 with convection pass 3.On after-flame burner hearth 5 relative side walls, be respectively equipped with the fine ash that matches with flame export 2 and after-flame burner hearth secondary wind jet pipe 9 from chimney arch 6 and high temperature smoke elimination chimney arch 7, the postmedian of its high temperature smoke elimination chimney arch 7 cuts off after-flame burner hearth 5 and after-flame flue 10, only is provided with the passage that after-flame burner hearth 5 is connected with after-flame flue 10 in high temperature smoke elimination chimney arch 7 front portions.
When operation is used, coal is thrown on the fixed grate 1, coal seam on the fixed grate 1 is thicker, send into by the part air that air compartment 13 will burn required, burnt under anaerobic condition in coal seam on the fixed grate 1, produce a large amount of raw gas, under the strong mixing of the combination air-spray that coal gasification burner hearth secondary wind jet pipe 8 sprays, burn simultaneously.Flame and uncombusted coal gas enter after-flame burner hearth 5 by the flame export on the partition wall 15 2, with the strong mixed combustion of combination air-spray from 9 ejections of after-flame burner hearth secondary wind jet pipe, high temperature smoke elimination chimney arch 7 makes the combustion zone keep the condition of high temperature simultaneously, eliminated the condition that produces black smoke, the solid particle that carries in the flue gas is split into the bottom of after-flame burner hearth 5 simultaneously, stopped from chimney arch 6 by fine ash, can be not rolled-up, can regularly remove.The flue gas that burning produces enters convection pass 3 by after-flame flue 10, carries out heat exchange with upper and lower drum 16,12 and last lower drum communicating pipe 17, has enlarged heat exchange area, discharges boiler then.
