Description

Hydrocarbon mixed combustion pressure boiler

Technical field

It is the pressure boiler of fuel with fire coal and living beings that the utility model relates to a kind of, and fuel can fully be burnt, and thermal efficiency height, heat transfer, endotherm area are big, the hydrocarbon mixed combustion pressure boiler of fuel saving.

Background technology

The boiler that existing market is sold all is to adopt traditional combustion method, and structure is that body of heater is arranged mostly, and the space forms the combustion chamber in the body of heater, and ventilating opening, fire grate, ashes chamber and fire door are arranged under the combustion chamber, and linking to each other with the combustion chamber is connected to smoke exhaust pipe; In the body of heater upper end fuel inlet is arranged, the stove inner combustion chamber is placed with water pipe, is connected to water return outlet and hot water outlet with water pipe.During use, by fuel inlet coal is inserted, the flue gas that coal combustion produced (heat) is to the water pipe heating, and the hot water in the water pipe enters heating system from hot water outlet, and heat radiation is after the water of return pipe turns back to the combustion chamber heating, as circulation repeatedly a bit.But the present following problem of boiler ubiquity in application: it is insufficient 1. to burn, and the discharging flue dust is big, because crater up, fuel is in the bottom, and the flue gas of generation burns insufficient to top; 2. fuel will go up that burning zone and fuel gas are isolated to be lost combustible gas in vain, also contain SO in the loss flue gas ₂Deng oxious component and pollute; 3. the terminal outlet of large-sized boiler all connects purifier at present, and involves great expense, and has increased the user installation production cost, consequently can only reduce discharging, can not be energy-conservation; 4. heat utilization ratio is low, makes heating surface area less relatively, if reach desirable heating effect, a large amount of fire coal of essential burning causes to waste energy.200920013391.5 number patent, 200920012920.X patent are applicant's development technology in recent years, but its heat-absorbing structure and combustion chamber still exist unreasonable part aspect structural design.

Summary of the invention

The utility model purpose is in order to solve many defectives that prior art exists, the hydrocarbon mixed combustion pressure boiler that a kind of sufficient combustion, heat-absorbing structure advanced person and heat transfer rate are fast, the thermal efficiency is high, fuel saving need not cleaner again to be provided.

The technical solution of the utility model is for achieving the above object: a kind of hydrocarbon mixed combustion pressure boiler, comprise body of heater, exhaust outlet, charge door, fire grate, Hui Cang, combuster, accent wind advance the oxygen supply combustion mechanism of oxygen door, crater, composition, the heat absorption cycling mechanism of forming by inside and outside water jacket, intake-outlet, it is characterized in that: the combustion chamber is surrounded by hearth water sleeve, the bottom, combustion chamber is provided with fire grate, parallelly with fire grate is provided with semicircle crater, and the crater place is provided with vertical fire bars; The Hui Cang both sides and the rear portion that are positioned at below the combustion chamber are equipped with air register, and there is perpendicular quirk in the outside, combustion chamber; Above the combustion chamber by middle inner water sleeve, the heat-absorbing chamber that divides inner water sleeve and peripheral water jacket to be communicated with and to form, at middle inner water sleeve, divide be respectively equipped with on the inner water sleeve in the quirk hole, divide the quirk hole, in, be the horizontal quirk of connection combustion chamber between the branch inner water sleeve.

The middle inner water sleeve that constitutes heat-absorbing chamber described in the utility model is isosceles triangle with the branch inner water sleeve and alternately lays multilayer; Near the body of heater top vent be the branch inner water sleeve, near combustion chamber top hearth water sleeve is middle inner water sleeve.

Utilize the utility model can make fuel reach multistage until thorough burning: the main gas component that burning first produces is carbonaceous gas, carbon monoxide, hydrogen; Through burning for the second time and for the third time, with regard to thorough all combustibles of after-flame of energy, the utility model is to design on the basis of hydrocarbon mixed combustion normal pressure power boiler, be that with the difference of normal-pressure boiler the design of this structure in the stove pays attention to pulling force in arc anti-, make boiler under the effect of pressure, stressed even, anti-pressure ability is strong, has prolonged service life.The utility model compared with prior art has the following advantages:

1, energy-saving and emission-reduction.Fuel combustion is abundant, and the energy transformation ratio of fuel can reach more than 98%; Than conventional boiler fuel saving more, energy-conservation 60～70%, the airborne release flue dust reduces discharging more than 95% than conventional method, reaches direct reduction of discharging, need not to install additional dedusting and purifying device;

2, heat-absorbing structure uniqueness, heat energy utilization rate height.Burning is fierce, and thermal discharge is big, and temperature rises fast, and this boiler is in fierce fired state from start to finish, and adding how thick fuel in the combustion chamber does not influence normal combustion;

3, the fuel utilization is extensive.This boiler can burn with all solid combustibles such as coal, stalk, timber, and its project organization is simple, volume is little, cost is low, is easy to promote the use of can be used for uses such as villages and towns in rural areas family, the heating of group unit, cooking, bathing.

The specific embodiment

Below in conjunction with accompanying drawing the utility model specific embodiments is described in detail.

Shown in Fig. 1～3: combustion chamber 15 is positioned at the body of heater bottom, and combustion chamber 15 upper outside have charge door 2, and charge door 2 bottoms are oxygen supply door 3; The combustion chamber is surrounded by hearth water sleeve 14, and the bottom of combustion chamber 15 is provided with fire grate 17, is grey storehouse 4 below the fire grate 17; Parallelly with fire grate 17 be provided with semicircle crater 16, crater 16 places are provided with vertical fire bars 8; 4 both sides, grey storehouse and the rear portions that are positioned at below the combustion chamber 15 are equipped with air register 5, combustion chamber water jacket 14 outsides be perpendicular quirk 7.

Shown in Fig. 3～8: be the heat-absorbing chamber that is communicated with and surrounds by middle inner water sleeve 9, branch inner water sleeve 10 and peripheral water jacket 6 above the combustion chamber, quirk hole 12 on middle inner water sleeve 9, being provided with, being provided with branch quirk hole 11 on minute inner water sleeve 10, is the horizontal quirk 13 that is communicated with the combustion chamber at middle inner water sleeve with dividing between the inner water sleeve.The middle inner water sleeve 9 that constitutes heat-absorbing chamber is isosceles triangle with branch inner water sleeve 10 and alternately lays 2～3 layers; Near body of heater top vent 1 be branch inner water sleeve 10, near combustion chamber 15 top hearth water sleeves 14 are middle inner water sleeves 9.All inner water sleeves (middle inner water sleeve 9, branch inner water sleeve 10, hearth water sleeve 14) all are connected with the peripheral water jacket 6 of body of heater, and the exhaust outlet 1 that is positioned at the body of heater top is connected with horizontal quirk 13 and perpendicular quirk 7.

After fuel is sent into combustion chamber 15 from charge door 2, flame after lighting is from crater 16 ejections, enter perpendicular quirk 7, during burning from fire grate bottom, oxygen supply door, charge door three oxygen supplys, abundant to guarantee oxygen supply, can regulate three places oxygen supply ratio as required, reach optimum efficiency, regulate the size of stack draught simultaneously with air register, so that the control combustion intensity.After flame enters the heat absorption water jacket from perpendicular quirk, arrive discharge outlet through dividing inner water sleeve in the several layers, the hole, shunting of middle minute inner water sleeve and middle quirk hole force fiery flow point to close parallel motion, to increase endothermic effect, carry out recycling after heat is absorbed by water jacket.
