Abstract

The utility model discloses a built-in fuse primer type heat exchanging water-jacket for a domestic heating stove, comprising a water jacket and a fire cover. A circle of fuse primers are arranged in the water jacket, the openings of the two ends of the fuse primer are respectively arranged on the upper end and the lower end of the inner wall of the water jacket, and the fire cover which covers the upper end of the water jacket is arranged under the upper opening area of the fuse primers. The fuel gas which flows into the end openings of the fuse primers are escaped from the upper openings; when the fuel gas flows through the fuse primers, the heat energy is transmitted into the water outside the fuse primers through the heat transmission of the surface of a wall, and the exchange of the heat is accomplished through the surface of a wall. The fuse primers are utilized to exchange the heat, the time and the distance of the heat transmission are shortened, and the efficiency of the exchange of the heat is raised; besides, the purpose of saving the fuel is realized, and the utility model is suitable for the briquette and the scattered coal.

Description

Built-in flue type heat exchanging water-jacket for domestic heating stove

The utility model relates to the civil heating stove and accessory.

Existing domestic heating stove heat exchanging water-jacket, most have various heat exchange wings in the water jacket surface design, to strengthen the heat transfer sheet area, reaches the increase heat exchange amount, improves the purpose of heat exchange efficiency.Their shortcoming be the heat exchange wing with water jacket in water can not directly contact, can only conduct heat to water jacket wall earlier, be transmitted in the water in the water jacket heat conduction time and distance, so heat exchange efficiency is lower again by wall.

The purpose of this utility model is a kind of domestic heating stove heat exchanging water-jacket of design, utilizes the fuse primer of arranging in the water jacket directly to carry out heat exchange, has shortened heat conducting time and distance greatly, increases substantially heat exchange efficiency, reaches fuel-saving purpose.

The utility model domestic heating stove built-in flue type heat exchanging water-jacket is made up of water jacket, fire lid.The inner upright crooked fuse primer of a circle that evenly distributes of said water jacket, the two ends difference opening of fuse primer is at the two ends up and down of water jacket.Said fire covers at position, water jacket upper end, is in below, fuse primer upper shed district.

Combustion gas is subjected to stopping of fire lid, can not directly rise, can only pierce the fuse primer lower open end that is positioned at the water jacket lower end, rise by each bar fuse primer, overflow from the fuse primer upper open end and since fuse primer around be water, at gas-flow during through fuse primer, conduct heat a large amount of thermal energy conduction in water by wall, finish sufficient heat exchange.Simultaneously, the water jacket inwall below the fire lid is accepted the radiant heat of combustion gas, carries out the auxiliary heat exchange.

The utility model compared with prior art, heat exchange efficiency is further enhanced, and is capable of saving fuel more than 20%.

The utility model water jacket is suitable for moulded coal and diffusing coal.

Illustrate that accompanying drawing is as follows:

Fig. 1 is the utility model domestic heating stove built-in flue type heat exchanging water-jacket's a structural representation.

Accompanying drawings embodiment is as follows:

The utility model domestic heating stove built-in flue type heat exchanging water-jacket is by water jacket (1), and the fire lid (2) two large divisions form.Said water jacket (1) internal diameter equates with tile (3) internal diameter, adapts to the turnover of moulded coal or diffusing coal, is full of water between water jacket inwall and the outer wall.Fuse primer (4) places water in the cover, around water jacket (1) the inwall circle that evenly distributes.The two ends of fuse primer (4) are opened on the upper and lower side of water jacket (1) inwall respectively, are welded with a circle supporting base (5) on water jacket (1) internal face below the upper open end of fuse primer (4).Said fire lid (2) is an external diameter and the cast iron dome that water jacket (1) internal diameter equates, covers on supporting base (5), and the top of fire lid (2) exposes the suitable for reading of fuse primer (4).Combustion gas is subjected to stopping of fire lid (2), can not directly rise, can only pierce the end opening of fuse primer (4), rise along fuse primer (4) inner chamber, from fuse primer (4) effusion suitable for reading, because fuse primer (4) outside is a water, during combustion gas process fuse primer (4), a large amount of heat energy are absorbed by wall and import in the water, and it is very low to flow out fuse primer (4) fuel gas temperature suitable for reading, thereby finishes main heat exchange.Simultaneously, combustion gas is conducted heat with radiation mode to water jacket (1) inwall in the cylindrical shell of the end sealing of being made up of fire lid (2) and water jacket (1) inwall, finish the auxiliary heat exchange.

Claims (2)

1, a kind of domestic heating stove built-in flue type heat exchanging water-jacket, it is characterized in that forming by assemblies such as water jacket, fire lids, there are the many crooked fuse primers that vertically distribute said water jacket inside, opening is at the upper and lower side of water jacket inwall respectively at the two ends of fuse primer, and said fire covers at position, water jacket upper end, is in below, fuse primer upper shed district, combustion gas is subjected to stopping of fire lid, pierce the fuse primer end opening, rise by the fuse primer inner chamber, from fuse primer effusion suitable for reading.

2, according to the said domestic heating stove built-in flue type of claim 1 heat exchanging water-jacket, it is characterized in that the fuse primer of said water jacket inside is the 4-12 root at the number that the water jacket periphery of inner wall distributes, the fuse primer internal diameter is 9～20 millimeters, pipe thickness is the 1-3 millimeter.
