Description

Efficient domestic heating boiler

Technical field

The utility model relates to heating plant, is specially a kind of efficient domestic heating boiler.

Background technology

Existing domestic heating stove comprises the body of heater that has water jacket, the water heating casing in the body of heater usually, the direct UNICOM of water heating casing in its furnace water jacket and the body of heater, form omnibearing UNICOM, communication between furnace water jacket and the water heating casing, like this, the water temperature basically identical of the temperature of body of heater outside and heating stove delivery port, water in furnace water jacket and the heating water jacket as a whole, temperature rises simultaneously or descends simultaneously with the temperature of body of heater outside, the temperature of body of heater outer surface is higher, cause the part heat to run off from body of heater is outside, the thermal efficiency of heating stove is not high.There is defective in the structure of existing domestic heating stove combustion chamber, and fuel combustion is insufficient, not only causes the further decline of the thermal efficiency, and Fuel Consumption is big, and its discharged flue gas dust content height, causes environmental pollution.

Summary of the invention

The utility model solves the problems referred to above and the defective that existing domestic heating boiler exists, and provides a kind of performance better domestic heating boiler.

The utility model is to adopt following technical scheme to realize: efficient domestic heating boiler, comprise in the body of heater that has water jacket and the body of heater its and have the water heating casing that flue gas portals, furnace water jacket is by the cross over pipe of body of heater outside and the water heating casing UNICOM in the body of heater, water inlet communicates with furnace water jacket, and the water heating casing in delivery port and the body of heater communicates.The water heating casing of furnace water jacket and body of heater forms crossfire through the cross over pipe of body of heater outside, recirculated water at first enters furnace water jacket from water inlet and preheats, enter the water heating casing through cross over pipe, in the water heating casing, lead heating, heat major part in the burner hearth of the furnace body is absorbed by the water heating casing, make the water temperature of delivery port be higher than body of heater appearance temperature, can accelerate the circulation rate of recirculated water, and body of heater appearance temperature is relatively low, the heat of body of heater appearance runs off also few, thereby improves the thermal efficiency of heating boiler.

The utility model is provided with on the top of burner hearth of the furnace body by interior ring surface and has the secondary air mechanism that the ring bodies vane in wind hole, the blast pipe that communicates with the vane inner chamber constitute, and secondary air mechanism is supported on the body of heater by blast pipe.The thermal current that contains coal gas that produces in the burner hearth of the furnace body forms second-time burning down the combustion-supporting of secondary air above secondary air mechanism, make fuel combustion abundant, increases the temperature in the body of heater, and reduces the pollution of fume emission.

Have the bypass flue that extends downward the body of heater pit on the fume emission flue of body of heater, be provided with the fume emission control panel of band drive link on it in the bypass flue, delivery port at heating boiler is provided with a temperature controller, be fixed with backguy on the action component of temperature controller, the drive link on the other end of backguy and the fume emission control panel is fixed.Described temperature controller is the control assembly that engine cool systemic circulation, partial circulating are controlled in general being used on the automobile.When the delivery port temperature is higher when reaching the operating temperature of temperature controller, the action component of temperature controller ejects, and affects backguy and drive the fume emission control panel by drive link to open, make the bypass flue unimpeded, the suction force of flue collector descends, and has reduced the burning degree of fuel, thus fuel saving; When the delivery port temperature drops to the reset temperature of temperature controller, the action component of temperature controller resets, and flue gas row control panel resets in the bypass flue, and flue collector recovers its suction force, increase the burning degree of fuel, thereby the burning degree of fuel can be regulated automatically according to the circulating water temperature of delivery port.Simultaneously, set up the bypass flue after, can increase the sedimentation of dust in the flue, the dust of deposition is imported pit, reduce discharging dust in flue gas content, increase environment protecting.

The utility model can make fuel combustion abundant by the architecture advances to existing domestic heating boiler, reduces thermal losses, the loss of body of heater outer surface, has improved the thermal efficiency of boiler.The temperature of the recirculated water of boiler can realize automatic adjusting.The dust of boiler emission flue gas and the content of oxious component are low, and boiler is low to the pollution level of environment.
