Description

Boiler type liquid fuel vaporizing burner

The utility model belongs to steam-boiler formula liquid fuel evaporation burner.

In using production processes such as coal system gas and coking, a large amount of byproducts being arranged---thick methyl alcohol need be used, and at present, countries in the world are the hybrid fuel of primary raw material promoting with methyl alcohol all, and as the part of domestic energy, wide market is arranged.Apply the main utensil of aforesaid liquid fuel at present, the key problem in technology of this kitchen range is the quality of liquid fuel evaporation.Liquid fuel evaporation kitchen range in the past comprise the through type vaporizer, on vaporizer or below superheater is housed, outside both, be with air chamber, its upper limb is provided with main fire hole, the escape pipe of vaporizer is connected with superheater tube, burns through control valve, gas jets, induction tunnel and air chamber to fire hole then.Because the vaporization part adopts straight-through structure, does not have the savings and the separation function of gas-liquid two-phase.Therefore, when thermic load increases, must cause vaporization insufficient, produce the yellow flame of violent paroxysmal and make liquid fuel enter air chamber, it is very incomplete to burn.In addition, existing evaporation burner is the head or the employing bar shaped fire hole of the sealing of employing center mostly, auxiliary air wretched insufficiency, CO in the flue gas _α=1(is converted to the carbon monoxide content that coefficient of excess air α equals at 1 o'clock, down together) generally up to more than 0.10%, substantially exceed family expenses kitchen range standard C O _α=1＜0.05% requirement.

The purpose of this utility model provides a kind of steam-boiler formula liquid fuel evaporation burner.

In order to achieve the above object, the utility model is taked following measures, its vaporizer is annular steam-boiler, feed tube upwards stretches into inner 1/4～3/4 and forms overfall from the bottom of a pan, escape pipe upwards reaches the top from the bottom of a pan, the oral area of escape pipe is higher than the inlet plane all the time, and its oral area has a ring-shaped groove, along groove a group aperture is arranged.

This steam-boiler formula liquid fuel evaporation burner, it is good to have the heat load adjustment performance, and flame is steady and audible, behind the assembling kitchen range; Carbon monoxide content CO in the flue gas _α=1＜0.03%, and the thermal efficiency is up to 58.8%, than existing liquid fuel evaporation kitchen range fuel savings 10-15%, the key technical indexes is equivalent to gas kitchen ranges A and gives level.

Conforming to figure below explains detailedly.

Fig. 1 is a steam-boiler formula liquid fuel evaporation burner A-A profile.

Fig. 2 is a steam-boiler formula liquid fuel evaporation burner top view.

Fig. 3 is annular steam-boiler expanded view.

The annular steam-boiler (1) that is positioned at the burner middle and upper part is the metal tube that a cross section is flat, its garden round angle is 320 °, closed at both ends, and feed tube (2) upwards stretches into 1/4～3/4 of inside from the bottom of a pan, form overfall, have the feed liquor and the overflow effect that keep level balance; Excess liquid is sent back to feed tube under the effect of pressure for vaporization.The top about 2/3 of annular steam-boiler (1) is the pressed gas after vaporizing, escape pipe (3) upwards extend into the top from the bottom of a pan, at its oral area one ring-shaped groove is arranged, along groove a group aperture is arranged, has the gas-liquid separation effect, gas flows out from the aperture group, after the control of needle valve (4) thermic load, deliver to annular superheater tube (5), its inlet end links to each other with (4), the outlet side is connected with gas jets (6), and gas further is heated in (5), improves temperature, to guarantee that the gas that enters induction tunnel (7) is in superheat state, accomplish that flame combustion is stable.In the periphery of annular steam-boiler and superheater tube is the burner air chamber, forms via disjunctor fire lid (8) and shell (9), and the eaves of with groove is arranged at the top that the disjunctor fire covers, and the upper limb flange of it and shell constitutes main fire hole (10).The secondary fire hole of two astragal tangential tilt is arranged on the straight tube top of disjunctor fire lid, and its flame is aimed at annular steam-boiler and superheater tube respectively, provides vaporization required heat, and disjunctor fire lid can take out from the upper end, convenient cleaning.In addition, locate respectively to be equipped with spray point (12) and (13), composition " dual ignition " system giving heat dish (11) and main fire hole (10).During igniting, be added with the high voltage pulse of 15000V at their discharging gap, and formation continuously sparking, the ignition combustion device, wherein spray point (12) works when cold start, spray point (13) then works when hot emphasis, and therefore when hot accident extinguishing, it is just very safe, convenient to put alkene again.
