Abstract
The utility model relates to a vertical type spiral combustion boiler, comprising a boiler hearth and a smoke outlet pipe. The half circumference of the inner wall of the boiler hearth on the upper part of a lower fire door is orderly provided with a heat storage insulating layer and an upper fire grate. A partition wall is arranged between the heat storage insulating layer and the upper fire grate. A fire through passage is formed in the space between the outer wall of the partition wall and the inner wall of the boiler hearth. The space of the boiler hearth above the upper fire grate forms an upper burning cavity. A lower burning cavity is formed between the heat storage insulating layer and the lower fire grate. The utility model has the advantages of compact structure, convenient operation, powder coal and briquette burning, strong adaptability of the coal type, high heat efficiency, and small smoke dust discharge amount when the coal is added and burnt. The utility model solves the defect that the existing vertical boiler has insufficient burning and overproof smoke exhaust. The utility model can be used for steam, heating, boiled water drinking, etc.
Description
The utility model relates to a kind of vertical combusting boiler that revolves, and belonging to generally has the fluid heater of heat-generating device field.
Existing vertical boiler mostly is the double-layer inverse burning fire grate structure, the broken smalls that can't burn, and the coal adaptive capacity is poor, and the thermal efficiency is low, and environmental protection easily exceeds standard during coal, is difficult for reaching environmental requirement.
In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of smalls that can fully burn, and adapts to all kinds of coals, and compact conformation, the vertical combusting boiler that revolves that the flue dust discharge capacity is little can provide steam, heating and drinking water with it.
The purpose of this utility model is finished in the following manner: it comprises burner hearth and pipe, it is characterized in that along being provided with accumulation of heat insulating course and upper fire-grating successively on the inboard wall of burner hearth half cycle of lower furnace door top, between the edge, the inner of accumulation of heat insulating course and upper fire-grating dividing wall is set, the space of dividing wall outer wall and inboard wall of burner hearth forms the passage that overdoes, the above furnace cavity of upper fire-grating forms combustion chamber, constitutes combustion chamber down between accumulation of heat insulating course and the lower fire grating.
In order to make the combustion chamber can independent burning, the structure that above-mentioned vertical upper fire-grating, dividing wall, accumulation of heat insulating course and the inboard wall of burner hearth that revolves combusting boiler surrounded be more than half Cylinder of hollow.
In order to make the combustion process continous-stable, the inboard wall of burner hearth directly over the passage that overdoes has the combustion-supporting arch of half garden shape.
Burn out upper fire-grating for fear of thermal-flame, between dividing wall top and upper fire-grating, be provided with the fire grate trustship of logical recirculated water.
In the utility model when work,, when the lower fire grating coal, the thermal-flame flue gas that following combustion chamber produces is sent to the secondary wind facies mutual effect that combustion chamber and tornadotron are sent here by the passage that overdoes, and fully disturbance is fully burnt in the thermal-flame of last combustion chamber; When the upper fire-grating coal, the pre-burning gas that last combustion chamber produced, the thermal-flame that is descended combustion chamber to be sent here by the passage that overdoes ignites, and still fully burns at last combustion chamber, and upper and lower two combustion chambers play complementary effect.Because the abundant disturbance of secondary wind and high-temperature flue gas, thereby produce the powerful combustion effect of revolving.Accumulation of heat insulating course, dividing wall and combustion-supporting arch are made by refractory material, and the accumulation of heat insulating course can be accumulated certain heat, make down combustion chamber remain high temperature; Combustion-supporting arch has certain combustion-supporting and guide effect to flame, make whole combustion process continous-stable, in order to reduce smoke discharge amount, the pipe upper end on burner hearth top is provided with the waste heat courage, the waste heat courage has the effect that stops with gravitational dust collection to flue dust when absorbing waste heat.
The vertical combusting boiler that revolves of the utility model because of set up combustion chamber in burner hearth, can make burning complementation between the upper and lower combustion chamber; can adapt to broken smalls and moulded coal, the coal adaptive capacity is strong, because sufficient combustion; help environmental protection, the characteristics of having given prominence to the vertical boiler compact conformation again simultaneously.
Embodiment to utility model is further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
See figures.1.and.2, the utility model comprises burner hearth 8 and pipe 5, above the lower furnace door 14, along be provided with successively on the burner hearth 8 inwall half cycles accumulation of heat insulating course 13, on ash door 12, upcast ventilation pipe 11, upper fire-grating 10, upper furnace door 9 and tornadotron 7, between accumulation of heat insulating course 13 and the upper fire-grating 10 inner edges dividing wall 21 is set, combustion chamber 23 and following combustion chamber 19 on the formation constitute the passage 20 that overdoes between dividing wall 21 outer walls and burner hearth 8 inwalls.In order to make the combustion chamber 23 can independent burning and obtain preferable combustion efficiency, be the large semicircle cylinder of hollow with the space that burner hearth 8 inwalls are surrounded by upper fire-grating 10, dividing wall 21, accumulation of heat insulating course 13.In order to obtain stable, a continuous combustion efficiency, burner hearth 8 inwalls directly over the passage 20 that overdoes have semicircle combustion-supporting arch 6.Burn out upper fire-grating 10 for fear of thermal-flame, between dividing wall 21 tops and upper fire-grating 10 inner edges, be provided with the fire grate trustship 22 of logical recirculated water.
When the lower fire grating coal, the thermal-flame flue gas that lower fire grating 18 produces is sent to the secondary wind that upper fire-grating 10 and tornadotron 7 send here fully to be mixed, and fully burns on last combustion chamber 23; When upper fire-grating 10 coals, the high-temperature flue gas that upper fire-grating 10 is produced, the high-temperature flame that is descended combustion chamber 19 to send here falls, and upper and lower combustion chamber 23,19 forms the complementary situation of burning.Overdo passage 20 and combustion-supporting arch 6 can be induced down the trend of the flame and the pre-burning fume of high temperature of combustion chamber 19 preferably, and can make the combustion process steady and continuous.Water jacket between pipe 5 and the boiler shell 4 is fluid heat cycles district.Waste heat courage 2 can fully absorb waste heat and flue dust had and stop and the gravitational dust collection effect.Flue dust can be removed by placing the ash removing opening 3 that links with waste heat courage 2 on the boiler shell 4; Slag can be removed by last ash door 12 and ash outlet 16 respectively, one time wind provides by lower air conduit 17 and upcast ventilation pipe 11, secondary cyclone provides by secondary air channel 15 and tornadotron 7 respectively, the secondary wind of last combustion chamber 23 is the strongest to the disturbance of thermal-flame flue gas, accumulation of heat insulating course 13 can be accumulated certain heat, makes down combustion chamber 19 remain high temperature.
