Abstract

The utility model relates to a preheater for a liquid fuel range. A cover is fixed to the preheater, a pipe joint is fixed to the preheater and the cover, and the end of the pipe joint extends into the cover, a flow quantity control rod is arranged in a hole of the pipe joint, a liquid inlet pipe is connected with the pipe joint, and holes are arranged in the cylindrical surrounding wall of an opening of the cover. The utility model has the advantages of simple structure, good fuel combusting effect, no red flame, no black fume, convenient use, reliability, etc. Besides, the flow quantity of preheating liquid fuels can be controlled, and the utility model is suitable to be used a preheater of a liquid fuel range.

Description

Preheater for liquid fuel burner

The utility model relates to a kind of preheater of liquid fuel cooker.

The existing cooking stove that uses liquid fuel, direct combustion of liquid fuel heating generating tube is adopted in its liquid fuel preheating mostly, this preheating method is easy to generate flourishing and black smoke, more obvious when particularly burning the high heating value liquid fuel, though also have some liquid fuel cookers also to adopt some smoke consuming apparatuses, flourishing and black fire still appears in cooking stove combustion system easily under the temperature condition with higher.The orifice restriction of employing principle control flow is also arranged, though can play certain smoke effect, because of aperture stops up easily, in addition, preheater is different at the smoke effect of each temperature section, still flourishing and over-emitting black exhaust can take place in the use.

The purpose of this utility model provides a kind ofly can control preheating with liquid fuel flow and combustion efficiency preheater for liquid fuel burner preferably.

Task of the present utility model realizes with following mode: a kind of preheater for liquid fuel burner, on the preheating body, be fixed with cover, pipe joint is fixed on preheating body and the cover, and be loaded on the cover bottom, its termination puts in the cover, the flow-control bar is housed in the hole of pipe joint, and feed tube connects with pipe joint, and is porose on the uncovered cylindrical periphery-wall of cover.Hole on the cover is the combination in hole or slit or hole and slit.

The utlity model has simple in structure, the preheated liquid fuel flow rate can be controlled, fuel combustion efficiency does not well produce flourishing and black smoke, characteristics such as easy to use, reliable, is suitable for the preheater of making liquid fuel cooking range.

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

Cover 7 is one and is bent into the uncovered tube at a no end with sheet metal, is furnished with 50 to 150 holes 9 covering on 7 the perisporium.Cover 7 is fixed on on steel or the castiron preheating body 6.Joint 5 is welded on preheating body 6 and the cover 7, and pipe joint 3 is spun in the joint 5, and flow-control bar 4 plugs are contained in the hole of pipe joint 3, and pipe joint nut 2 is enclosed within that pipe joint nut 2 is tightened on the pipe joint 3 on the feed tube 1.Flow-control bar 4 and the hole of pipe joint 3 are gapped 10, and liquid fuel flows through in the gap.

Use: during the kitchen range preheating, pre-heating fuel enters in the gap 10 that the endoporus of flow-control bar 4 and pipe joint 3 forms enters cover 7 from feed tube 1.Spray point 8 carries out preheating to the ignited fuels that enter in the cover 7 to the kitchen range generating tube, because a lot of holes 9 that replenish air are arranged on the cover 7, so over-emitting black exhaust and flourishing can well eliminate fuel combustion the time.

During preheating, whole preheater also obtains heating, when the fiery normal combustion of master, also can heat preheater.As after turning off main fire, need again to continue again to use, preheater temperature this moment is than higher; at once if pre-heating fuel enters cover 7 very soon, fuel can be vaporized after running into hot preheating body 6 at once, produces a large amount of fuel vapours, cover 7 can not in time replenish a large amount of air, can occur flourishing with smolder.So preheating this moment will slowly enter in the cover 7 with fuel, flow fuel must reduce.After the preheater temperature raises, fuel is during through the formed gap 10 of the endoporus of flow-control bar 4 and pipe joint 3, some carburretion, the certain pressure of formation gap 10 in, this pressure can stop fuel to enter fast in the cover 7, plays the purpose of automatic adjusting pre-heating fuel flow.

Claims (2)
