Description

Double water jacket combustion gas furnace

It is the furnace of fuel that the utility model relates to coal gas (liquefied gas).

At present, be used for various traditional furnace of warming, the overwhelming majority is to be fuel with coal, these furnaces in use, exist following shortcoming: 1, mean calorie is low.Because oxygen supply deficiency in the stove, coal produce carbon monoxide and over-emitting black exhaust when burning, and the over-emitting black exhaust that causes when adding coal and a large amount of carbon monoxide that night, banking produced etc., reduced the mean calorie of coal burning; 2, heat exchange efficiency is low.Coal produces part volatility tobacco tar owing to oxygen supply is not enough when burning, these tobacco tar condense on the stove inner water jacket wall through cooling, and adsorb a large amount of dust, and its heat-blocking action has reduced the heat exchange efficiency of furnace significantly; 3, lack waste-heat recovery device.Because heat exchange efficiency is low, causes the temperature of the waste gas that enters flue and atmosphere to be much higher than water temperature, in the wasting while, has further reduced the thermal efficiency of furnace; 4, heat supply is untimely.Mainly show morning, owing to bank up a fire for a long time, furnace temperature is low, intensification is slow, and room temperature is lower again, is difficult to improve rapidly indoor temperature; 5, to the harm of human body.Generally all contain a certain amount of sulphur and compound thereof in the coal, generate sulfur dioxide in when burning, the carbon monoxide of Sheng Chenging, dust etc. in addition, these products have bigger excitant and toxic and side effect to people's the breathing and the circulatory system; 6, environmental pollution.Comprise pollution on the environments such as slag, dust, carbon monoxide, sulfur dioxide, especially comparatively serious to the pollution that family room causes; 7, work degree of adding is big.Because the large usage quantity of coal, carrying coal, slag, and add charcoal, slagging-off etc. become the bigger operational work of intensity, especially concerning the people that live in high-rise building, especially one heavy and lock broken work.

The purpose of this utility model provides a kind of function of recovering waste heat that has, thermal efficiency height, heats up rapidly, and health, non-environmental-pollution, what can cook, heat up water simultaneously is the double water jacket combustion gas furnace of fuel with coal gas (liquefied gas).

Above-mentioned purpose of the present utility model is realized by following technical scheme: furnace is by burner, body of heater, chimney, upper water sleeve, lower water jacket, last heat pipe, following heat pipe, the heat absorption fin, delivery port, water inlet, igniter, compositions such as cross over pipe, its structure is, having one in the body of heater upper end is used to cook, the firehole of heating up water, a burner has been placed in the lower end of firehole, around firehole, also be provided with water jacket, this water jacket communicates with the water jacket that is arranged at the chimney lower end and constitutes lower water jacket jointly, be placed with another burner in the lower end of chimney, a delivery port is arranged in the upper end of lower water jacket, this delivery port communicates with the water inlet of radiator by pipeline, and there is a water inlet its lower end of upper water sleeve that is arranged on the chimney, this water inlet then communicates with the delivery port of radiator by pipeline, in chimney, also be provided with at least one and go up heat pipe and at least one following heat pipe, two mouths of pipe of last heat pipe communicate with the two ends up and down of upper water sleeve respectively, two mouths of pipe of following heat pipe communicate with the two ends up and down of lower water jacket respectively, last, on the following heat pipe, be welded with several heat absorption fins respectively, last, between the lower water jacket, also settled a cross over pipe, two mouths of pipe of this cross over pipe communicate with the upper end of upper water sleeve and the lower end of lower water jacket respectively, top at cross over pipe, also be provided with a gas vent, this gas vent can link to each other with vent valve or hutch water device (bucket), has the passage that at least one is used to provide oxygen on the antetheca of body of heater.In addition, in the inboard of body of heater front end, also settled a fireguard, with fire resistant directly-fired kiln body antetheca, on side wall of furnace, also settled general igniter respectively corresponding to two burners, whole body of heater is placed on a stove cashier's office in a shop, and this stove cabinet can be used for depositing articles for use such as round-bottomed frying pan, pot.

Technique scheme has constituted the utility model.Just time spent, to the burner air feed, when needing heating, the opening point firearm will be placed in the burner of chimney lower end and light, the high-temp waste gas that produces is discharged after water jacket and heat pipe heat absorption by chimney, flow to radiator by delivery port after water heat absorption in lower water jacket and the following heat pipe heats up, the cold water that flows back to from radiator then flows to lower water jacket by cross over pipe after water inlet enters upper water sleeve and last heat pipe and absorbs waste heat.When needs are cooked, when heating up water, are then lighted the burner that is positioned at the firehole lower end and close another burner, the high-temp waste gas of generation still by chimney through water jacket and heat pipe heat absorption back discharge.

The utility model compared with prior art has and heats up rapidly, thermal efficiency height, and easy to use, health, pollution-free can fully absorb advantages such as waste heat.

Below in conjunction with the embodiment accompanying drawing the utility model is specified:
