Abstract

The utility model relates to a domestic stove with a gravity heat-pipe. The utility model solves the problems of only water jacket, uneasy combustion of fuel coal, slow heating speed and low thermal efficiency of an existing domestic stove. An outer shell, stove bars and an inner lining are welded to form the water jacket, and a plurality of gaps are harmoniously distributed on the inner lining; each gap point is separately welded with a gravity heat-pipe. The utility model has the advantages that the gravity heat-pipes are harmoniously distributed in a stove body and parts of the bottom of the gravity heat-pipes are buried in fire to be directly contacted with the fuel coal when in use, the utility model has the advantages of rapid water heating in the water jacket and high thermal efficiency.

Description

The domestic burners that has gravity assisted heat pipe

The utility model is a kind of domestic burners, particularly a kind of domestic burners that has gravity assisted heat pipe.

Existing domestic burners has only water jacket, and coal-fired nonflammable, firing rate is slow, and the thermal efficiency is low.

The purpose of this utility model is, solves above-mentioned existing existing problem, provides a kind of thermal efficiency the high domestic burners that has gravity assisted heat pipe.

The utility model is achieved in that shell and fire bars, inner bag welding back form water jacket, is evenly equipped with several gap on inner bag, is welded with gravity assisted heat pipe respectively at opening position.

Advantage of the present utility model is, during use, because gravity assisted heat pipe is uniform in body of heater, and its bottom imbeds a part and can directly contact with coal-fired in coal fire, and the interior water of water jacket heats soon thermal efficiency height.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Describe in detail below in conjunction with accompanying drawing:

As shown in the figure, shell 1 forms water jacket 5 with fire bars 3, inner bag 4 welding backs, is evenly equipped with several gap on inner bag 4, is welded with gravity assisted heat pipe 6 respectively at opening position.Body of heater is provided with ash door 2, and chimney 10 is installed, and bell 8 is stamped in its upper end; Water jacket 5 is provided with water inlet 9, delivery port 7.

During use, the major part of gravity assisted heat pipe contact water jacket is when temperature is higher than 55 ℃, gravity assisted heat pipe is met water and is emitted latent heat, flows to the gravity assisted heat pipe bottom along tube wall again after the condensation, touch the high temperature coal seam after, gasification is risen again, goes round and begins again, and with regard to very fast water in the water jacket has been heated; Make the water jacket inner aqueous layer produce pressure reduction naturally like this, high-temperature water rises in the loop of closure, flows out from delivery port, and cold water flows into from water inlet thereupon, has formed the Natural Circulation of water.When needs were pressed the stove heating, the low calorific value coal of available water mixing pressed stove fire because coal-fired fire temperature is higher, and gravity assisted heat pipe some be embedded in the fire bed, so as long as temperature is higher than 55 ℃ in the burner hearth, the gravity assisted heat pipe in the fire bed is all in work.

Claims (1)

1, a kind of domestic burners that has gravity assisted heat pipe; Shell and fire bars, inner bag welding back form water jacket, it is characterized in that, are evenly equipped with several gap on inner bag, are welded with gravity assisted heat pipe respectively at opening position.
