Abstract

The utility model provides a domestic coal-fired energy-saving furnace. A plurality of declinate bending type distributing fins are arranged on the surrounding inner wall of a vaporizing sleeve section on the upper opening part of a main water jacket in a furnace body, heat-transfer area of a water jacket is enlarged, and the height of the sleeve body of the main water jacket is designed to threequarters to one half of the height of a fire grate to an inner furnace mouth. Temperature in a hearth is enhanced, fired coal is burned thoroughly, thermal energy conversion and utilization of a furnace device can be enhanced, and the utility model can be used for cooking and heating supply simultaneously. The utility model which is a novel domestic coal fired furnace has the advantages of novel structure, energy saving and easy use.

Description

Residential coal combustion type energy-saving heating furnace

The utility model relates to a kind of family life stove and accessory of application of solid fuels, especially a kind of coal-fired furnace that includes the heating water jacket at body of heater.

In known technology, existing residential coal combustion furnace mainly is made up of furnace main body, neck bush, main water sleeve and vaporization cover, load main water sleeve between furnace main body and neck bush, and the vaporization cover of main water sleeve connection fire door portion consists of the heating system of water.But because the vaporization cover on the existing stove and accessory main water sleeve mostly is circular snare, its heat transfer area is less, the heat absorption rate is lower, water jacket is surrounded on the burner hearth perisporium from top to bottom in addition, make that especially the temperature of lower coal combustion that easily causes on the low side is insufficient in the burner hearth, heat energy utilization and conversion ratio are low, also bring inconvenience to use.

The purpose of the utility model provides a kind of novel structure, makes coal combustion abundant, and heat energy transforms and the utilization rate height, novel coal stove and accessory energy-conservation, easy to use.

For achieving the above object, the technical scheme that the utility model is taked is: several pieces oblique bent gliding fins of load on the circumferential inner wall of main water sleeve upper oral part vaporization cover section in furnace main body, and the height of main water sleeve body is designed to fire grate to 3/4ths to 1/2nd of interior fire door (being burner hearth) height, a main water sleeve bottom load arc watt shape connection overlaps to body of heater bottom connection admitting pipe joint, the novel energy-conserving furnace that consists of.During use, after lighting stove fire, because having water jacket, the burner hearth bottom do not surround, thereby fire box temperature height, on fire fast, fired coal combustion fully, especially on the vaporization cover internal perisporium of main water sleeve upper oral part, several pieces oblique bent gliding fins have been installed additional, strengthened the heat transfer area of water jacket, the water that can fully absorb in the furnace heat heating water jacket makes it vaporization, accelerated the circulation rate of water, thus stove and accessory related radiator quick heating, again because the distributing fin in the vaporization cover section is oblique curved formula arranges, make stove fire by after in the shape of a spiral shape emit liter, thereby stove fire burning is prosperous.

Because the utility model has been installed oblique bent gliding fin on the vaporization cover section inwall of main water sleeve, and main water sleeve is selected to be designed to preferred height.Therefore, the utility model can make coal-fired fully burning than existing coal-fired furnace, and the heat that can fully absorb fuel and produced, the heat energy conversion and the utilization rate of stove and accessory are improved greatly, can cook with stove simultaneously and heat gas, and stove fire is prosperous, connect the radiator quick heating, its novel structure, design innovation, the saving energy, easy to use are a kind of novel residential coal combustion furnace.

Following structure drawings and Examples are described in further detail the utility model.

Fig. 1 is the cutaway view of the utility model embodiment concrete structure.

Fig. 2 be among Fig. 1 A-A to cutaway view.

Fig. 3 is the cutaway view of Fig. 1 along the B-B line.

Be labeled as in the accompanying drawing: 1 furnace main body, 2 distributing fins, 3 main water sleeves, 4 refractory lining covers, 5 covers, 6 titting water outlets.

Embodiment as shown in Figure 1, the utility model comprises: furnace main body (1), refractory lining cover (4), main water sleeve (3) and distributing fin (2).Between furnace main body (1) and refractory lining cover (4), clamp main water sleeve (3), main water sleeve (3) is positioned at the vaporization of fire door portion and overlaps several pieces oblique bent gliding fins (2) of load on the circumferential inner wall of section, the quantity of distributing fin can be provided with according to type of furnace size, and the best is that 10-26 sheet spiral shell rotating bending type or arc bent gliding fin are uniform.The height H of main water sleeve (3) body is a fire grate to 3/4ths to 1/2nd scopes of interior fire door (being furnace chamber) height G, and connects arc watt shape connection cover (5) admitting pipe joint (6) of furnace main body (1) bottom in succession in main water sleeve (3) bottom.

Claims (3)

1, a kind of residential coal combustion type energy-saving heating furnace, it comprises furnace main body (1), refractory lining cover (4), main water sleeve (3), it is characterized in that also comprising distributing fin (2), be positioned at the vaporization of fire door portion at main water sleeve (3) and overlap several pieces oblique bent gliding fins (2) of connection on the circumferential inner wall of section.

2, furnace according to claim 1 is characterized in that distributing fin (2) the best of the vaporization cover section load of main water sleeve (3) is that 10～26 spiral shell rotating bending types or arc bent gliding fin are uniform.

3, furnace according to claim 1 and 2, the height H that it is characterized in that main water sleeve (3) body is a fire grate to 3/4ths to 1/2nd of interior fire door height G, and connects arc watt shape connection cover (5) admitting pipe joint (6) of furnace main body (1) bottom in succession in main water sleeve (3) bottom.
