Abstract
A kind of horizontal Double-hearth coal-gasifying spray burn type energy-saving environment-friendly hot water boiler, it comprises coal gasification room, heating gas combustion chamber, rotate air distribution gas nozzle, fixed grate, combustion gas aid distributing pipe, coal gasification room aid distributing pipe, circulating water pipe, the compositions such as boiler body, adopt on coal gasification room and heating gas combustion chamber same level line and design, be located at the below of hot water cyclesystem, water leg partition wall is provided with in the middle of combustion chamber and coal gasification room, gas nozzle is located at the top of the middle water leg partition wall of vaporizer and combustion chamber in stove, coal gasification room produces coal gas after washing away to the last time, after carrying out air distribution mixing by rotation air distribution gas nozzle, spray to combustion chamber to burn, when combustion flame rises, the water back-turning plate be arranged on high temp. flue blocks, just in time meet with jet combustion flame, under the collision of two flames, combustion flame is made to form rolling combustion system, the favourable burnout rate that improve fuel, achieve coal conversion clean combustion.
Description
One, technical field
The utility model belongs to the energy-saving environment-friendly hot water boiler of coal gasification clean combustion, solves coal and directly to burn the problem of environmental pollution brought, achieve the right-about of coal burning mode
Two, background technology
Coal is occupied an leading position in China's energy production and consumption structure always, the pollution produced in the development and utilization of coal has caused China's environment and has had a strong impact on, and Coal Gasification is one of core technology of clean efficiency utilization, therefore, in present stage, application coal gasification is one of effective way solving atmosphere pollution, and it will be paid close attention to and apply widely.
China take coal as the country of main source of energy, the principal mode of coal utilization is directly burning, the dust pollution caused due to the direct burning of coal and the waste of the energy more and more serious, many cities are caused to carry out strict restriction to the direct fire coal of Industrial Boiler, time limit is carried out for low capacity coal-burning boiler eliminate, natural gas is used in requirement instead, town gas or oil burning boiler, but, for developed area or Small Urban, rural area, realize using clean fuel can be subject to the restriction of all many condition, therefore Innovation of Coal clean combustion of coal mode is the unique selection that solution coal high-efficiency utilizes decreasing pollution to discharge.
Three, summary of the invention
The horizontal twin furnace that the utility model provides burns gas spray burn type energy-saving environment-friendly hot water boiler, utilize the technology path of after-combustion of first gasifying, change the direct combustion system of coal, according to the design form of overall structure and three function combinations up and down, namely logical hot water cyclesystem is filled with in coal gasification room, combustion chamber and many places.Coal gasification room and heating gas Combustion chamber design on same horizontal line, hot water heat convection system is located at the top of coal gasification room and heating gas combustion chamber, be provided with water holding jacket partition wall between the chambers, and coal gas mixing aid distributing pipe is located in two Room therebetween water jackets, the top rotating air distribution combustion nozzle and be located at two Room water holding jacket partition walls, realize coal gas and namely produce and namely use.As can be seen from Figure 1, combustion chamber belongs to irregular square, top is connected with the water holding jacket consubstantiality of hot water cyclesystem, fill with for three of top circulation surrounding and Room, below two and lead to, recirculated water is made to fill with logical whole boiler, such thermal efficiency is improved, above irregular square combustion chamber, the both sides of exhaust gases passes are provided with the water back-turning plate water leg of two differing heights, two water back-turning plate water legs constitute combustion chamber fire contact plate, when combustion flame rises under the effect of two fire contact plates, flame is folded back, the flame that the flame be folded back just in time sprays with nozzle bumps against, the flame direction that two flames spray along nozzle burns to the below rolling of combustion chamber thus realizes the repeated combustion of combustible gas, high-temperature flue gas after burning enters horizontally-arranged water pipe heat convection district by exhaust gases passes, air is entered from exhaust opening after the heat exchange of three backhauls.
The utility model solves its technical problem, and the technical scheme adopted is; Utilize the conjuncted design of twin furnace, solve Coal Gasification clean combustion problem, utilize the flame of counter-fire technology and burner noz(zle) to liquidate technology, achieve the efficient burning of fuel.
Useful effect of the present utility model is: by the gasification of coal, improve fuel quality, facilitates the change of fuel combustion mode.
Four, accompanying drawing explanation
Fig. 1 is front view of the present utility model
Fig. 2 is side view of the present utility model
Five, detailed description of the invention
Boiler jacket (11) is communicated with coal gasification room (26) water leg with combustion chamber (8) with boiler inner sleeve (12) in FIG, coal gasification room (26) and the centre of combustion chamber (8) are provided with water leg (25) and are communicated with boiler water chuck, in the middle of vaporizer (26) and combustion chamber (8), the top of water leg is provided with gas nozzle (23), combustion gas aid distributing pipe (30) is provided with in water leg in the middle of coal gasification room (26) and combustion chamber (8), an aid distributing pipe (29) is provided with in the bottom of coal gasification room (26), secondary aid distributing pipe (5) is provided with in the bottom of combustion chamber (8), be provided with water back-turning plate (9) on the top of combustion chamber (8) and form high level matches with low level with the another end water back-turning plate of boiler inner sleeve (12), under the power of meeting of combustion flame below water back-turning plate (9), flame directly jumps on the flame that gas nozzle (23) just in time sprays with nozzle and bumps against, the flame direction that the flame bumped against sprays along nozzle rolls to combustion chamber (8) below, form flame rolling burning.High-temperature flue gas after burning enters heat convection flue through outlet (10), high-temperature flue gas enters second layer flue (13) by smoke intaking hole (21), third layer flue is entered again from smoke intaking hole (15), flue gas, after three times are washed away heat exchange, is discharged from exhaust opening (19).
In fig. 2, connect with steel plate (33) between the horizontally-arranged water pipe of boiler (32), thus make high-temperature flue gas in stove, define three backhauls.
