Description

Full fuel cyclone furnace

Technical field

The present invention relates to hot water production boiler, specifically provide a kind of full fuel cyclone furnace.

Background technology

The hot water production boiler (water jacket furnace) of conventional art, limit by structure, the fuel of identical type or ofapproximate categories mostly can only be used as thermal source, in order to the hot water amount that guarantees supply, improve the efficiency of heating surface, usually the inner bag in burner hearth is amplified and make, increase its superheating surface sum volume, improve efficiency of utilization.Shortcoming is: the volume of body of heater also can increase, and takes up room many during installation, and the consumptive material used during making is many, and cost of manufacture is raised, wasting space and resource, and excessive body of heater not only operating cost is high, can bring inconvenience when safeguarding and keep in repair; Further, inner bag volume becomes greatly, and the containing quantity of water also increases thereupon, causes fuel thermal energy to utilize and does not concentrate, and needs to increase firing rate; Hot water production boiler feed water mouth in conventional art is located at the bottom of body of heater usually, in use, because the temperature difference can produce the condensation globule (being commonly called as " perspiration ") near water inlet pipe and inner bag water inlet, be dropped in after globule aggegation on fuel, the combustion efficiency of fuel can be affected, and can cause inner bag temperature distributing disproportionation, the Assimilation and conductivity affecting heat energy transforms, and is a kind of harmful phenomenon.

Summary of the invention

The object of this invention is to provide a kind of full fuel cyclone furnace, the water jacket furnace of this technology can use various fuel, can solve the disadvantage that boiler water inlet pipe is perspired, and compared with the hot water production boiler of equal gabarit volume, its heat utilization efficiency is high, energy-conserving and environment-protective.

Technical scheme of the present invention is: full fuel cyclone furnace, comprise body of heater, body of heater is provided with water jacket, burner hearth is built with inner bag, be provided with gap between inner bag and water jacket inwall, it is characterized in that: the top of inner bag is provided with outlet pipe, the bottom of inner bag is communicated with bottom water jacket by tube connector, the top of water jacket is provided with water inlet pipe, the inwall of inner bag and water jacket is respectively equipped with some oblique grooves.

The profile of inner bag is cone wide at the top and narrow at the bottom.

Bottom inner bag and top is the arched top to courage sunken inside respectively, and the top of described burner hearth is recessed arched top.

Advantage of the present invention is: some oblique grooves add the heated surface area of water jacket inwall and inner bag, flame hot-fluid is made helically to increase along groove inclined-plane, hot-fluid is made to be attached to the surface of water jacket inwall and inner bladder outer wall all the time, effectively can improve the heat utilization efficiency of fuel, it is made to reduce the requirement that fuel produces heat energy, not only can use as kerosene, diesel oil, the fuel that the heat energy such as combustion gas are high, also such as timber can be used, coal cinder, the conventional fuel that the heat energy such as stalk are lower, compared with the hot water production boiler of gabarit volume equal in conventional art, its heat utilization efficiency is high, can save energy environmental protection, during normal use, cold water enters elder generation and mixes with the water in water jacket and become warm water from the top of water jacket, the exhaust-heat heating of pyrotechnics is utilized when flowing downward, eliminate main heated part condensation, enter inner bag again from tube connector after having heated, effectively can solve the disadvantage that boiler main wants heated portion to perspire, generation condensation globule position is arranged on the end that burner hearth waste gas is discharged simultaneously, because a large amount of dusts lands by the effect of the globule and moisture, decrease the pollution of dust emissions.Dust with moisture is dry gradually in decline process, because water produces oxygen in gasification, this part oxygen can play combustion-supporting effect, increase temperature value, make effective heated portion outer surface dry, uniformity of temperature profile, is beneficial to heat absorption, make fuel combustion more abundant, produce the effect of energy-conserving and environment-protective further; Between the inner bag of cone and water jacket inwall, gap is that bottom is wide, top is narrow, broad gap combustible can be allowed to contact more air fully carries out burning, the effect of assembling slowly-releasing flame or smoke heat energy can be played in narrow gap, improve efficiency of utilization further; The heat energy of flame can be gathered in depressed area bottom inner bag, and the depressed area of inner bag top and roof of the furnace can retain the heat energy of flue gas, and the heat energy that fuel is produced is fully utilized.
