Abstract

The utility model relates to a gaseous fuel stove, comprising a base, an air inlet pipe, a stove body, a bracket and a fire pressing ring. The stove body is an annular column whose lower base is sealed; the radial end is provided with an air reservoir which is externally projected; the lower part of the air reservoir is communicated with the inner cavity of the lower part of the stove body, and the upper part is connected with the air inlet pipe of which front segment is provided with a gas mixing chamber of which front end is provided with an air inlet air door. The fire pressing ring is hung at the outlet position of the upper end of the stove body; a carrier frame is arranged in the cavity of the middle of the stove body, and is sheathed on a guide post of the middle of the base; a pressing spring is arranged between the carrier frame and the guide post. The gaseous fuel stove uses a floating stove body so that the added material and the height of the flame can be adjusted. The utility model has the advantages of high thermal efficiency, and energy saving, and is especially suitable for the peasant household in mountain area.

Description

A kind of gas furnace

It is the gas furnace of fuel with biogas, coal gas, natural gas that the utility model relates to a kind of.

Used gas furnace, body of heater and support are relatively-stationary, when heating dissimilar vessel, height of its heating bottom surface and flame also is a definite value, be difficult for coordinating the optimum height of flame, thereby the thermal efficiency is low; Moreover combustion gas is directly to enter the combustion chamber through air inlet pipe, thereby the flare instability, and gas consumption is bigger.

The purpose of this utility model is: design that the relative support of a kind of body of heater is relocatable, after combustion gas enters air storage chamber by air inlet pipe, steadily enter the gas furnace of combustion chamber again, overcome and above-mentionedly be not.

The embodiment of gas furnace of the present utility model is: this gas furnace comprises base, air inlet pipe, body of heater, support, banking fire ring, body of heater is the circular cylinder of going to the bottom and sealing, its longitudinal end has the air storage chamber of outside protrusion, the bottom of air storage chamber communicates with the body of heater lower lumen, tracheae is repeatedly kicked on top, the leading portion of air inlet pipe is provided with gas mixer chamber, and the front end of gas mixer chamber is provided with inlet flap.The columned banking fire ring of the sealing of going to the bottom is equipped with through hook in the middle part in exit, body of heater upper end, in the cavity of body of heater carriage is arranged, and is sleeved on the guide pillar at base middle part, on the guide pillar between base and bracket, is set with stage clip, and body of heater can slide up and down along guide pillar.

Spacing b=1.5 between the internal and external peripheral wall in the internal and external peripheral wall of banking fire ring and body of heater exit～3mm, constitute the burner of this stove, burner plane, top and banking fire ring top plan range 1=2～3mm, high crater end face is answered on the plane, top of the carriage in the body of heater in the cavities, its height L=10～18mm.

For guaranteeing that combustion gas steadily enters the combustion chamber, be provided with gas mixer chamber (also playing first order depressurization) between air inlet pipe, mixed combustion gas is introduced into air storage chamber, once more decompression, air inlet through air storage chamber and lower end, combustion chamber enters the combustion chamber again, the height H of its air inlet=10～15mm.

Gas furnace of the present utility model can be coordinated the distance between heating thing and flare, reaches the best thermal efficiency; Moreover combustion gas is to enter the combustion chamber after the two-stage step-down, thereby flare is stable, the gas saving.This gas furnace is rational in infrastructure, and is novel in design, easy to manufacture, practical inexpensive, is particularly suitable for farmers in mountain area.

Gas furnace of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing is the structure chart according to the gas furnace that the utility model proposes.

Below in conjunction with the details of accompanying drawing detailed description according to the gas furnace that the utility model proposes.

This gas furnace is made up of base [1], air inlet pipe [4], body of heater [7], support [10], banking fire ring [8].Body of heater is the circular cylinder of going to the bottom and sealing, longitudinal end has the air storage chamber [3] of outside protrusion, the bottom of air storage chamber communicates with the lower lumen of body of heater, height H=the 10mm of its air inlet, tracheae is repeatedly kicked on the top of air storage chamber, and the leading portion of air inlet pipe is provided with a bucket-shaped gas mixer chamber [6], and being equipped with what can pull out commentaries on classics in its front end is sheet metal, have a plurality of uniform holes on the plate face, constitute air door [5].The middle part in exit, body of heater upper end, through three uniform hooks [9] the banking fire ring is housed, the spacing b=2mm of the internal and external peripheral wall in exit, the internal and external peripheral wall of banking fire ring and body of heater upper end constitutes the burner of this stove, and the plane, top of banking fire ring is higher than plane, burner top, and it exceeds height I=2mm.In the cavity at body of heater middle part carriage [11] is housed fixedly, there is a hole this carriage center, and is sleeved on the guide pillar [12] at base middle part, and composition is slidingly matched, and the plane, top of carriage exceeds the burner end face, and it exceeds height L=15mm.

Claims

1. gas furnace, comprise base, air inlet pipe, body of heater, support, the banking fire ring, it is characterized in that body of heater is the circular cylinder of going to the bottom and sealing, its longitudinal end has the air storage chamber of outside protrusion, the bottom of air storage chamber communicates with the body of heater lower lumen, tracheae is repeatedly kicked on top, the leading portion of air inlet pipe is provided with gas mixer chamber, the front end of gas mixer chamber is provided with inlet flap, and the columned banking fire ring of the sealing of going to the bottom is equipped with at the middle part in exit, body of heater upper end through hook, in the cavity at body of heater middle part carriage is arranged, and be sleeved on the guide pillar at base middle part, on the guide pillar between base and bracket, be set with stage clip.

2. gas furnace according to claim 1, be the spacing b=1.5～3mm between the internal and external peripheral wall of the internal and external peripheral wall of banking fire ring and body of heater outlet, constitute the burner of this stove, burner plane, top and banking fire ring top plan range l=2～3mm, high crater end face is answered on the plane, top of the carriage in the body of heater in the cavities, its height L=10～18mm, air inlet height H=10～15mm that the air storage chamber bottom communicates with the bottom of furnace body inner chamber.
