Abstract

The utility model relates to a domestic internal heating gas boiler which uses coal gas, liquefied petroleum gas and gasified oil furnace as heat source, utilizes water outside fire and fire inside water, and consists of boiler wall, pipeline and combustion chamber. It is characterized in that the outer air duct fan is communicated with the outer air duct full-sealed cover, and the combustor is positioned at the lower part of the combustion chamber. The radiating fins are connected on the wall of the furnace pipe, and the radiating pipes are connected with the wall of the furnace pipe after being communicated with the combustion chamber. Its advantages are high utilization rate of heat energy, no need of consuming oxygen in room, small occupied space and suitable for household.

Description

Household internal heating type fuel gas boiler

The utility model belongs to mechanical metal pressure container field, is a kind of family expenses internal heat type gas fired-boiler specifically.

At present existing boiler is all done fuel with coal or oil, transports and deposit equal inconvenience, and the flue dust coal ash influences environment, uses the operation element amount big, and area occupied is many, is not suitable for family and uses.Say on the structure that internally existing boiler is that fire burns in burner hearth, water flows in water pipe, and is fiery outside water, and the heat of a fire part is as adding hot water, and another part heat but directly contacts the furnace wall and the consumption of scattering and disappearing, and heat utilization efficiency is lower.

The purpose of this utility model then is the problem at above-mentioned existence, designed and a kind ofly done heating source with coal gas, liquefied petroleum gas and oil gasification furnace, utilize water outside fire, the family expenses internal heat type gas fired-boiler that fire burns within water, thus obtain required hot water of people and steam.

Technical solution of the present utility model:

A kind of family expenses internal heat type gas fired-boiler of forming by pot wall, pipeline, combustion chamber, it is characterized in that the hermetically sealed cover 16 in outer air channel blower fan 21 and outer air channel is communicated with, burner 15 is positioned at the bottom of combustion chamber 14, fin 12 is connected on the furnace wall 17, and radiating tube 7 communicates with combustion chamber 14 and then links to each other with furnace wall 17.

Furnace wall 17 is the double-wall flue.Its concrete structure is: wall of inner container 19 is enclosed within the wall of outer container 20, has cavity between wall of inner container 19 and the wall of outer container 20, and communicates by inside and outside current siphunculus 18.

Advantage of the present utility model:

One, the utility model is rational in infrastructure, utilizes the internal heat type flue tube structure, and water is outside flue, fire is wrapped by water, the heat of fire burns must just can be transmitted to the furnace wall by water, and reduced and scattered and disappeared and consumption, moreover the fin on the inner furnace, radiating tube and compound furnace wall, increased contact-making surface and the heat conduction of velocity of fire with water, so quick heating, heat energy utilization rate height, energy-conservation; Its two owing to adopted the outer air channel of totally-enclosed outdoor introducing air combustion-supporting, need not consume indoor oxygen, both made under flame-out gas leakage situation and also intoxication accident can not take place; Its three because the utility model adopts combustion gas or oil gasification furnace as thermal source,, thereby dwindled the occupation of land space greatly so that boiler volume can design is less, be more suitable for family's use.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model double-wall flue tube structure vertical view.

Fig. 3 is the utility model double-wall flue tube structure schematic diagram.

Below in conjunction with accompanying drawing the utility model is further described:

From emptying, the water filling in boiler of the shared pipe 13 of water inlet, how much water can be by 5 indication of water level meter in the stove, close into each valve of water, open outer air channel blower fan 21, outdoor air is directly introduced the hermetically sealed cover 16 in outer air channel with by combustion-supporting, then open the gas igniting, make fuel pass through burner 15 and in combustion chamber 14, burn.Thereby make furnace wall 17, fin 12, radiating tube 7 heating, heat conduction feedwater, water is heated up, burnt gas is discharged outdoor by flue 8, as this stove is the double-wall structure, fire is burning in combustion chamber 14, and enters radiating tube 7 by the rising of the folder dead level between wall of inner container 19 and the wall of outer container 20, with heat conduction feedwater.Inside and outside current siphunculus 18 plays the effect of balancing water temperature, water temperature and furnace pressure can pass through thermometer 6, Pressure gauge 3 is observed, set pressure as surpassing in the stove, pressure-reducing valve 4 meeting automatic deflations, malfunctioning as pressure-reducing valve, pressure rises, and safety valve 2 can be open-minded voluntarily, and is not quick-fried to guarantee body of heater, can be with hot-water outlet pipe 10 valve open as need with hot water, hot water can be sent to water consumption device under the promotion of furnace pressure, can be by emptying with hot water as low water level, the shared pipe 13 of intaking, each triple valve is open-minded, and water is delivered to water consumption device, as need steam, can open steam valve 1 steam is sent,, triple valve can be opened to floss hole emptying as the boiler rinsing or the waste water of draining.

Set up reflective insulation layer 9 outside the boiler wall, heat-insulation layer 11 is wrapped in outside the reflective insulation layer 9, scatters and disappears to reduce heat.

Will reach the automatic control water inlet as boiler, water inlet element automatically can be installed on water level meter 5, and set up water pump on inlet pipeline, can reach has automatic make-up water under the pressure condition in stove.
