Abstract
The utility model relates to a multipass high-efficiency heating boiler, which comprises a boiler body, a water jacket arranged in the ring wall of the boiler body, a combustion chamber arranged inside the water jacket, a coal inlet arranged at the upper end of the combustion chamber, a furnace grate arranged in the combustion chamber and an ash discharge chamber which is arranged at the lower end of the furnace grate and is communicated with the combustion chamber. The upper end of the combustion chamber is provided with a chimney. The periphery inside the combustion chamber is vertically provided with circulating water pipes communicated with the water jacket. The boiler body is provided with a deslagging port which passes through the water jacket and is communicated with the combustion chamber. In the utility model, a plurality of circulating water pipes are additionally arranged in the combustion chamber around the inner wall of the combustion chamber to reach effect of multipass heating, sufficiently increase heating area, make heat sufficiently utilized and reduce heat loss so as to improve heat efficiency, reduce coal consumption and reduce heating cost of the boiler.
Description
Technical field
The utility model relates to the efficient heating boiler of a kind of many backhauls.
Background technology
The present widely used heating boiler especially most burning coal of civil heating boiler directly heats water jacket, thermal losses height wherein, and heat energy can not get sufficient utilization.
The utility model content
Technical problem to be solved in the utility model provide a kind of in the combustion chamber adding circulated water pipe reach the efficient heating boiler of many backhauls that can effectively improve the thermal efficiency of many backhauls heating.
The utility model adopts following technical scheme:
The utility model comprises body of heater, is arranged on the water jacket in the body of heater ring wall, the combustion chamber that is arranged on the water jacket inwall, the coal feed point that is arranged on the upper end, combustion chamber, the ash discharge chamber that is connected with the combustion chamber that is arranged on the fire grate of lower end, combustion chamber and is arranged on the fire grate lower end, upper end, described combustion chamber is provided with chimney, described combustion chamber inner circumferential is evenly distributed and vertically is provided with the circulating water pipe that is connected with water jacket, and described body of heater is provided with and passes the cinder notch that removes that water jacket is connected with the combustion chamber.
Good effect of the present utility model is as follows:
The utility model installs many circulating water pipes additional around the combustion chamber inwall and reaches many backhaul heating in the combustion chamber, fully increase heating surface area, and heat is fully used, reduced thermal losses, thereby improved the thermal efficiency, reduced coal consumption, reduced the cost of boiler heat supplying.
