Abstract

The utility model discloses a double-hearth coal gasification boiler, aiming at solving the problems that when the boiler with the existing structure is in use, the combustion smoke is too much, the environment is influenced, and the operation is not convenient. A hearth is internally provided a left hearth and a right hearth which are separated from each other by a fireproof material wall provided with a fire through hole; the upper parts of the left and the right hearths are respectively provided with a flue turnover plate used for controlling alternate combustion; the upper parts of the left and the right hearths are also respectively provided with a high-temperature hot air outlet which is communicated with a heat absorption chamber; a coaling hole is arranged at the lower part of the front side of a shell of a furnace body of each hearth; a slag outlet is positioned under the coaling hole; a dust removal hole is arranged at the upper part of the front side of the shell of the furnace body; a smoke outlet is arranged at the lower part of the rear side of the shell of the furnace body; a rear dust removal hole is arranged under the smoke outlet; and the heat absorption chamber is internally provided with a vertical heat pipe heat absorption water pipe, horizontal type heat absorption water pipes arranged in a staggered way, and a fin-type return stroke water pipe. The double-hearth coal gasification boiler is simple in structure; by adopting a double-hearth structure, the double-hearth coal gasification boiler ensures the whole process to be free from smoke and dust and achieves the effect of clean combustion; and the double-hearth coal gasification boiler widely uses coal, molded coal, biomass fuel, oil gas and the like as fuel.

Description

The double-hearth gas boiler
Technical field
This practicality newly relates to boiler, is specifically related to a kind of double-hearth gas boiler-type.
Background technology
The coal gasification boiler of existing double-furnace structure; Comprise just burn gas generation chamber and reverse-burning gas generation chamber that top interconnects; The generation chamber that just burning gas bottom is provided with just burns fire grate, is just burning the fire grate below high-pressure blast and water-stop pond are set, and the top is the generating region that just burns gas; Reverse-burning gas generation chamber bottom is provided with anti-burn grate, and the anti-burn grate below is provided with the combustion chamber and has the crater that is communicated with the district of absorbing heat, and the top is the reverse-burning gas generating region; Secondary high-pressure wind is established in reverse-burning gas generating region top, and heat absorption is provided with heat-absorbing water pipe in the district, and top, heat absorption district has exhanst gas outlet.The coal-fired coal gasification boiler of existing structure exists combustion fumes too much in use, and the boiler over-emitting black exhaust influences environment, and environmental protection is not up to standard; Fireman's inconvenient operation; The problem that has potential safety hazard.
Summary of the invention
The utility model be for the boiler that solves existing structure in use, exist combustion fumes too much, the boiler over-emitting black exhaust influences environment, the problem of inconvenient operation, and a kind of double-hearth gas boiler is provided.
The utility model is realized through following technical scheme:
A kind of double-hearth gas boiler; In the burner hearth with two burner hearths about being provided with burner refractory material wall and being divided into, about two upper furnace be provided with the flue turnover panel of control alternate combustion, each upper furnace also offers high temperature hot gas and exports and be communicated with heat-absorbing chamber; The body of heater shell front side bottom of each burner hearth offers a coal filling hole; The coal filling hole below offers slag notch, and body of heater shell front side top offers dedust port, and side lower part offers outlet flue behind the body of heater shell; The outlet flue below offers the back dedust port, is provided with the horizontal type heat-absorbing water pipe and the fin type backhaul water pipe of vertical heat pipe heat-absorbing water pipe, interlaced arrangement in the heat-absorbing chamber.
During use; When adding left hearth through left stove gate, fuel closes the flue turnover panel of left hearth earlier; Let flame pass through the fixed carbon high-temperature region that burner gets into right bearth of crossing of high-temperature refractory wall, the hot gas that the back of fully burning produces gets into heat-absorbing chamber through right high-temperature flue gas outlet; In like manner; When fuel adds right bearth through right stove gate; Through after the crossing fixed carbon high-temperature region that burner gets into left hearth and fully burn of high-temperature refractory, the hot gas of generation gets into heat-absorbing chamber by left high-temperature flue gas outlet to the flue turnover panel of closing right bearth earlier, after vertical heat pipe heat-absorbing water pipe heat absorption by flame; After horizontal sucked hot water pipe and the heat absorption of fin type backhaul water pipe, discharge atmosphere by flue outlet.
The utility model is simple in structure, adopts double-furnace structure, can be vertical structure and also can be horizontal type structure, and whole process smokeless and dust free can reach the effect of clean combustion, can extensive practical coal, fuel such as moulded coal, bio-fuel, oil gas.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the vertical view of the utility model;
Fig. 3 is the side view of the utility model;
Among the figure: dedust port, 9-horizontal type heat-absorbing water pipe, 10-fin type backhaul water pipe, 11-cross burner, the outlet of 12-high temperature hot gas, 13-heat-absorbing chamber behind 1-burner hearth, 2-flue turnover panel, 3-coal filling hole, 4-slag notch, 5-dedust port, 6-refractory material wall, 7-outlet flue, the 8-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
A kind of double-hearth gas boiler as shown in Figure 1; In the burner hearth with two burner hearths 1 about being provided with burner 11 refractory material walls 6 and being divided into; About two burner hearth 1 tops be provided with the flue turnover panel 2 of control alternate combustion; Each upper furnace also offers high temperature hot gas outlet 12 and is communicated with heat-absorbing chamber 13, and the body of heater shell front side bottom of each burner hearth offers a coal filling hole 3, and coal filling hole 3 belows offer slag notch 4; Body of heater shell front side top offers dedust port 5; Side lower part offers outlet flue 7 behind the body of heater shell, and outlet flue 7 belows offer back dedust port 8, is provided with the horizontal type heat-absorbing water pipe 9 and the fin type backhaul water pipe 10 of vertical heat pipe heat-absorbing water pipe 8, interlaced arrangement in the heat-absorbing chamber 13.
