Abstract

The utility model discloses a multifunctional miniature boiler with heat pipes. The utility model is a small solid fuel boiler which is used for local heating, wherein, a stove and a cooker are combined into a whole in the utility model. The utility model is composed of a stove type burner and a relatively independent heat pipe type heat exchanger. The utility model is characterized in that a refluxing plate is arranged on a flue, an upper spacer plate arranged between the flue and a main water tank is provided with a set of heat pipes, and the fire grate of the burner is a water-cooled fire grate. The utility model has the advantage of multiple function, and the thermal efficiency which is high can reach 75%. The utility model is especially suitable for supplying heat for small areas.

Description

Multifunctional miniature boiler with heating pipe

The utility model relates to a kind of boiler, also be a kind of kitchen range simultaneously, specifically a kind of local heating heat supply, small-sized solid combustion boiler of cooking stove one of being used for.

The boiler that generally is used for small size heating, or a kind of pure heating plant, or it is a kind of based on cooking stove, waste heat heating is the multi-function device of assisting, the former function singleness can not satisfy the independently many-sided demand in life unit, and latter's thermal efficiency is low, heating effect is bad, and the heating that only suits in small size is used very much.

The purpose of this utility model is to adopt advanced hot pipe technique, and a kind of thermal efficiency height is provided, and function is many, and the miniature boiler of stove and kitchen range one newly designs.

Following mode can realize goal of the invention of the present utility model:

The utility model is made up of the burner of relatively independent band water-cooling wall and heat exchanger two parts of adopting heat pipes for heat transfer, be connected with water pipe through the flue connecting leg between the two, it is characterized in that, the fire grate of burner is a kind of anti-overheated water-cooled grate that is communicated with water-cooling wall, plate is flowed at the place once at the heat exchanger flue, flue gas is through the circulation of back flow plate top, upper spacer between flue and the main water box is provided with one group of heat pipe, the heat pipe two ends lay respectively in main water box and the flue cavity, and are divided into two groups of front and back by back flow plate.

Good effect of the present utility model:

The utility model adopts hot pipe technique, and the back flow plate in the flue intercepts the flue gas streamlined flow, increases the flue gas flow path, strengthen heat exchanger and wash away area, can obtain higher thermal efficient, burner is selected water-cooling wall and water-cooled grate for use, reduces thermal losses, improve service life, the relatively independent setting of burner and heat exchanger both can be used as a kind of cooking stove, can heat up water and cook, can be heat supply in the heating again, be particularly suitable for using in the independent dwelling house of non-central heating.

Accompanying drawing is the utility model structural representation.

Describe the utility model most preferred embodiment in detail below in conjunction with accompanying drawing:

Cooking stove formula burner 1 and heat-pipe heat exchanger 2 are relatively independent, burner 1 exhaust opening throat links to each other through the flue connecting leg with heat exchanger 2 chimney intakes, burner 1 water-cooling wall inner chamber links to each other through water pipe with main water box, burner 1 adopts the cooking stove formula structure that goes up the fire door charging, the side is provided with clean-out door 4, shoot door 8 is positioned at clean-out door 4 belows, fire grate 6 is a kind of water-cooled grates, its inner chamber is communicated with water-cooling wall, back flow plate 3 is set in the flue of heat exchanger 2, flue gas can only flow through back flow plate 3 tops, thereby increase the flue gas flow path, and make not clean-burning flue gas carry out second-time burning, significantly reduce the flue gas environmental pollution at back flow plate 3 rears, the wall of heat exchanger 2 still is a water-cooling wall, upper spacer between its main water box and the flue is all arranged one group of heat pipe 10, and heat pipe 10 is vacuum sealing tubes that an amount of thermal conductive fluid medium is housed in a kind of, and the two ends of pipe are stretched into respectively in main water box and the flue, hot gas (water) outlet 9 is located at the main water box top, and water inlet 7 is positioned at burner 1 water-cooling wall.

The utility model efficiency of combustion economizes on coal 30% up to 75% than like product, and the residential heating of homalographic can doublely be done cooking stove again in both having can be, and sufficient combustion, and smoke pollution is little.

Claims (1)

1, a kind of multifunctional heat pipe miniature boiler, form by relatively independent cooking stove formula burner and heat-pipe heat exchanger, be connected with water pipe through the flue connecting leg between the two, it is characterized in that: the fire grate of burner is a kind of anti-overheated water-cooled grate that is communicated with water-cooling wall, plate is flowed at the place once at the heat exchanger flue, flue gas is through the circulation of back flow plate top, upper spacer between flue and the main water box is provided with one group of heat pipe, the heat pipe two ends lay respectively in main water box and the flue cavity, and are divided into two groups of front and back by back flow plate.
