Abstract
The invention discloses a double-hearth coal-gasifying boiler, which solves the problems that when the boiler with a traditional structure is used, burning smoke dust is overmuch to influence an environment, and the boiler is inconvenient to operate. The inner part of a hearth is divided into a left hearth and a right hearth through a refractory-material wall at a fire-passing opening, the upper parts of the left hearth and the right hearth are respectively provided with a flue-turning plate for controlling alternate burning, the upper part of each hearth is also drilled with a high-temperature hot-air outlet communicated with a heat-absorbing chamber, the lower part at the front side of a furnace-body shell of each hearth is drilled with a coal-feeding opening, a slag outlet is drilled below the coal-feeding opening, the upper part at the front side of the furnace-body shell is drilled with a dust-cleaning opening, the lower part at the rear side of the furnace-body shell is drilled with a smoke outlet, a rear dust-cleaning opening is drilled below the smoke outlet, and a vertical-type heat-pipe heat-absorbing water pipe as well as a transverse-type heat-absorbing water pipe and a fin-type return water pipe which are arranged in a staggered mode are arranged in the heat-absorbing chamber. The double-hearth coal-gasifying boiler has a simple structure, a double-hearth structure is adopted, no smoke or dust exists in the whole process, the effect of clean burning can be achieved, and fuel, such as coal, molded coal, biological fuel, oil gas and the like can be widely used by the double-hearth coal-gasifying boiler.
Description
Technical field
The present invention relates to boiler, be specifically related to a kind of double-hearth gas boiler.
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 present invention 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 present invention is achieved by the following technical solutions:
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 the high temperature hot gas outlet and is 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, body of heater shell front side top offers dedust port, side lower part offers outlet flue behind the body of heater shell, the outlet flue below offers the back dedust port, is provided with vertical heat pipe heat-absorbing water pipe in the heat-absorbing chamber, the horizontal type heat-absorbing water pipe of interlaced arrangement and fin type backhaul water pipe.
During use, when adding left hearth by left stove gate, fuel closes the flue turnover panel of left hearth earlier, allow cross the fixed carbon high-temperature region that burner enter right bearth of flame by the high-temperature refractory wall, the hot gas that the back of fully burning produces enters heat-absorbing chamber by right high-temperature flue gas outlet; In like manner, when fuel adds right bearth by right stove gate, the flue turnover panel of closing right bearth earlier by flame by after the crossing fixed carbon high-temperature region that burner enters left hearth and fully burn of high-temperature refractory, the hot gas that produces enters heat-absorbing chamber by left high-temperature flue gas outlet, after vertical heat pipe heat-absorbing water pipe heat absorption, after horizontal sucked hot water pipe and the heat absorption of fin type backhaul water pipe, discharge atmosphere by flue outlet.
The present invention 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 a front view of the present invention;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is a side view of the present invention;
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
The present invention will be further described below in conjunction with accompanying drawing.
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, the body of heater shell front side bottom of each burner hearth offers a coal filling hole 3, 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, outlet flue 7 belows offer back dedust port 8, are provided with vertical heat pipe heat-absorbing water pipe 8 in the heat-absorbing chamber 13, the horizontal type heat-absorbing water pipe 9 of interlaced arrangement and fin type backhaul water pipe 10.
