Description

Miniature boiler and the gentle dual burner of cooking range light hydrocarbon oil

Technical field

The present invention relates to a kind of miniature boiler and the gentle dual burner of cooking range light hydrocarbon oil, belong to heat power equipment.

Background technology

Fuel is the important energy source that the mankind depend on for existence, yet development along with society, need to consume a large amount of energy, energy scarcity is day by day all to increase at present, people are at the new energy of active research exploitation for this reason, for example use fire coal to be restricted at urban heat supplying, it is not only environmental pollution problem and mainly is the resource anxiety, the cost height, individual household heating or household heating will be progressively carried out in the central heating in most cities, and be fuel with coal no longer, adopt combustion gas, electric heating, though sanitation and hygiene, for the area that lacks combustion gas and electric power still difficulty, heating and life fuel problem are badly in need of solving in these areas for this reason, the fuel that uses in miniature boiler and catering trade is diesel oil, kerosene and oil liquefied gas, light-hydrocarbon fuel can not use existing kitchen range, and the burner of existing light-hydrocarbon fuel all is to adopt preheating method with light-hydrocarbon fuel gasification earlier igniting again, explosive, combustion instability, more dangerous.

Summary of the invention

Purpose of the present invention is just in order to solve the problem of above-mentioned existence, utilize miniature boiler and the cooking range light hydrocarbon oil gentle dual burner of petroleum by-product lighter hydrocarbons for fuel, thereby when solving the energy, provide reliable burner, make human more environmental protection of life, more save.

The objective of the invention is to realize by following technical proposal:

Miniature boiler and the gentle dual burner of cooking range light hydrocarbon oil, it comprises housing 1, air intake reducing pipe 16, nozzle 14, the fixedly ears or side handles of a utensil 20, oil inlet pipe, air inlet pipe, magnetic valve, fire rod 13, igniting pin 3 and ion detection probe 15, it is characterized in that:

(a) there is a taper type boss 8 with the housing bottom disjunctor at the center in the housing of scroll casing shape, and side air inlet reducing pipe is that a wind mixed chamber 21 is connected with the blower fan outlet;

(b) in enclosure interior one converter 2 is installed, converter top is bowl-type, periphery has outer lug boss, boss bottom surface and housing oral area join, the a plurality of 15-35 of sloping inwardly degree are arranged on the barrel of boss bottom, with the double angle of axial angle 15-30 degree help wind aperture 10, the converter bottom is straight tubular, bottom periphery has a plurality of axial 15-25 degree otch 12, bottom and housing bottom join, bottom outer wall and shell chamber form secondary mixing air compartment 22, inwall and taper type boss bottom outer wall form three wind mixed chamber 23, there is round ring boss 24 at the converter middle part, the uniform 4-15 degree that slopes inwardly is arranged on the round ring boss, with the combustion gas discharge port 11 of the double angle of axial angle 4-20 degree, the round ring boss endoporus cooperates with taper type boss top;

(c) have one to projecting inward boss on housing top, the fresh air inlet 9 of the secondary combustion air of a plurality of uniform 1-25 degree that slope inwardly is arranged on the boss;

(d) taper type boss inner chamber is a water cooling chamber 19, is installed into water pipe 6 and outlet pipe 7 on the cooling chamber bottom end cover 5, and outlet pipe connects magnetic valve;

(e) on taper type boss top cylindrical shape heat collector 17 is housed, the heat collector bottom periphery has a plurality of uniform breach 18.

Burner of the present invention is applicable to oil, two kinds of fuel of gas.

Owing to take technique scheme to make the technology of the present invention have following advantage and effect:

A) adopt the heat build-up method to open the fuel gas particulate strand of gaseous state in the combustion process in high-temperature heating state following moment of heat collector, accelerate burning velocity, increased heat, reduce discharge of harmful gases,

B) this burner adopts the internal water cooling means, and the low weight chemical by-product that can directly burn can not produce the flame instability phenomenon,

C) direct burns gasoline, light oil, petrochemical by-product can directly be lighted various combustion gas,

D) flame temperature height can reach 1300 degree, and the calorific value height can reach 11300-13000kcal/kg, and thermal efficiency height can reach 85-90%,

E) simple to operate, smokeless, tasteless, nontoxic, safe in utilization, expense is low, and heat supply speed is fast, and the automaticity height is free from environmental pollution.
