The utility model has the structure that a guide rail is fixed to the bottom of the interior of a boiler casing; a gas stove which can slide out of the gas boiler is arranged on the guide rail; the upper part of the interior of the boiler casing is provided with coiled pipes which are overlapped and interlaced; outlets on the bottoms of the coiled pipes are connected with water returning pipes; outlets on the upper parts of the coiled pipes are connected with water supply pipes; the top of the boiler casing is communicated with a fume discharging passage through a boiler cover. The utility model has the advantages of no pollution of discharged exhaust gas, energy saving, simple and convenient operation and use, safety and reliability.

Description

The energy-saving gas hot water space heating boiler

The utility model belongs to boiler manufacturing technology field, particularly relates to a kind of improvement of small-sized heat supply stove.

At present,, divide with the type of using the energy though be that the kind of miniature boiler of unit heating usefulness is more with the family, the overwhelming majority be with coal or fuel oil as the energy, the high problem of these boiler ubiquity energy consumptions, what coal-burning boiler had also pollutes environment.

The purpose of this utility model provides a kind of energy-saving gas hot water space heating boiler.

The technical solution of the utility model is as follows:

The furnace shell inner bottom part is fixed with guide rail, has on the guide rail slidably to go out the outer gas furnace of furnace shell, at the furnace shell internal upper part coil pipe of stack straggly is arranged, and the outlet at bottom of coil pipe takes back water pipe, and the top outlet connects water pipe, and the furnace shell top is communicated with smokejack by bonnet.

The utility model has the advantages that: the waste gas of discharge is pollution-free, saves the energy, manipulates simple and convenient, safe and reliable.

Fig. 1 is a structure cut-away view of the present utility model;

Below in conjunction with accompanying drawing scheme is described further.

Wherein: the 1st, stove leg, the 2nd, combustion gas connects mouth, the 3rd, switch, 4 guide rails, the 5th, gas furnace, 6 furnace shells, the 7th, bonnet, the 8th, smokejack, the 9th, upper hose, the 10th, return pipe, the 11st, coil pipe.

Gas furnace can pull out or advance in furnace shell by guide rail, is convenient to igniting or maintenance; Furnace shell integral body is obturator, is beneficial to save the energy; Outlet at bottom at coil pipe takes back water pipe, and the top outlet connects water pipe, and gas furnace is after the stove internal combustion, and to being placed on the coil pipe heating on top, heated hot water flows out from upper hose, and return pipe replenishes cold water again in coil pipe; The furnace shell headroom also can be thought flue simultaneously, and waste gas discharges out of the furnace from smokejack; Structure is greatly simplified and realized normal pressure heating.

Claims (1)

1, a kind of energy-saving gas hot water space heating boiler, form by gas furnace (5), stove leg (1), furnace shell (6), smokejack (8), it is characterized in that: furnace shell (6) inner bottom part is fixed with guide rail (4), have on the guide rail (4) and slidably go out the outer gas furnace (5) of furnace shell (6), the coil pipe (11) that stack straggly is arranged at furnace shell (6) internal upper part, the outlet at bottom of coil pipe (11) takes back water pipe (10), and the top outlet connects water pipe (9), and furnace shell (6) top is communicated with smokejack (8) by bonnet (7).
