A pre-combustion chamber is arranged on a hearth on the lower part, a combustor port is arranged on the pre-combustion chamber, the lower part of the pre-combustion chamber is provided with a slag outlet of the hearth, a water-cooled wall of a lower body and a lower header of the lower body are arranged in the pre-combustion chamber, and the lower header of the lower body is communicated with a lower boiler barrel. The hearth on the lower part is communicated with a hearth on the upper part, the hearth on the upper part is composed of a water-cooled wall of a front wall, a water-cooled wall of a back wall and water-cooled walls of both side walls, the hearth on the upper part is communicated with a combusted ash chamber which is communicated with a convection heating surface, wherein the convection heating surface is composed of a convection bank which is connected with an upper boiler barrel and the lower boiler barrel to form a circulation loop; the water-cooled wall of the front wall and the upper boiler barrel are connected into a circulation loop by a front downtake, the water-cooled walls of the side walls of the hearth on the upper part and the upper boiler barrel are connected into a circulation loop by a side downtake, and the water-cooled wall of the back wall and the lower boiler barrel are connected into a circulation loop by a back downtake; the upper boiler barrel is communicated with an upper header of the lower body by a communicating pipe.
Description
Technical field:
The utility model relates to a kind of combustion apparatus, particularly a kind of boiler.
Background technology:
Water-coal-slurry is a kind of novel coal-based clean fuel, uses water-coal-slurry and can solve the problems such as environmental pollution that coal burning causes.But existing coal water slurry boiler ubiquity efficiency of combustion is low, and the thermic load height easily produces problems such as high temperature slagging scorification in the stove, and the ash discharge problem of slagging tap can not solve.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the efficiency of combustion height can not produce the coal water slurry boiler of high temperature slagging scorification.
Technical solution of the present utility model is:
A kind of coal water slurry boiler, comprise lower furnace, it is characterized in that: lower furnace has precombustion chamber, precombustion chamber is provided with burner opening, the precombustion chamber bottom is provided with the burner hearth slag notch, be provided with the lower body water-cooling wall in the precombustion chamber, be provided with the lower body next part case that is communicated with lower drum in the precombustion chamber, lower furnace communicates with upper furnace, upper furnace is by preceding, rear water wall, the both walls water-cooling wall is formed, upper furnace communicates with burning chamber, burning chamber communicates with convection heating surface, convection heating surface is made up of convection bank, on convection bank connects, lower drum becomes closed circuit, and front water wall and upper drum connect into closed circuit by preceding down-comer, the side water wall of upper furnace, upper drum is linked to be closed circuit by side down-comer and side collection case, the rear water wall of upper furnace and lower drum are linked to be closed circuit by the back down-comer, and upper drum is communicated with the lower body upper collecting chamber by cross over pipe.
Convection bank partly has dividing wall on the heat-resisting coagulation of multiple tracks, offers smoke ventilator on the body of wall, and smoke ventilator is positioned at different height on the adjacent heat resistance concrete dividing wall.Below convection heating surface, set out apparatus for ash.
The utility model is rational in infrastructure, and the efficiency of combustion height can not produce the high temperature slagging scorification, and the ash discharge of slagging tap is convenient.
