Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings.
[0013] Such as figure 1 In the shown double-hearth coal gasification boiler, the furnace is divided into two left and right furnaces 1 by a refractory wall 6 provided with fire ports 11, and the upper parts of the left and right furnaces 1 are provided with flue flaps 2 for controlling alternate combustion. The upper part of each furnace is also provided with a high-temperature hot gas outlet 12 to communicate with the heat-absorbing chamber 13; There is a dust cleaning port 5 on the upper front side, a smoke outlet 7 on the lower rear side of the furnace shell, a rear dust cleaning port 8 below the smoke outlet 7, and a vertical heat pipe 8 for absorbing hot water in the heat absorption chamber 13 , Horizontal heat absorption pipes 9 and finned return water pipes 10 arranged in a staggered manner.

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 [0001] The invention relates to a boiler, in particular to a double-hearth coal gasification boiler. Background technique [0002] The existing coal gasification boiler with double hearth structure includes a normal-fired gas generating room and a reverse-fired gas generating room connected to each other at the upper part. Water-sealed pool, the upper part is the normal burning gas generation area; the lower part of the anti-burning gas generation room is equipped with a counter-burning grate, the combustion chamber is set under the counter-burning grate and a fire outlet is opened to communicate with the heat-absorbing area, and the upper part is the counter-burning gas Occurrence area: Secondary high-pressure air is set above the anti-burning gas generation area, heat absorption pipes are installed in the heat absorption area, and a flue gas outlet is opened above the heat absorption area. When the coal-fired coal gasification boiler of the existing struct...
