Description

Biomass fuel reverse combustion type boiler
Technical field
The utility model belongs to the boiler technology field, relates in particular to a kind of biomass fuel reverse combustion type boiler.
Background technology
Boiler is thermal power transfer equipment, also is pollution sources simultaneously.Thermal efficiency height and pollution level are to weigh two important indicators of boiler.Traditional boiler structure normally is comprised of pot and stove.Topmost parts are burner hearth and boiler drum in the boiler body.Burner hearth claims again the combustion chamber, its structures shape combustion system and used fuel, be the major part that determines the thermal efficiency and pollution.Because they all are to adopt the positive theory of combustion, mostly take coal as fuel, in combustion process, produce a large amount of pernicious gas contaminated environment such as sulfur dioxide, and the thermal efficiency is low, generally about 80%.
Because coal resources worsening shortages; countries in the world all utilize technology carrying out biomass combustion; to solve the problem that energy crisis was produced, well-known, living beings are discarded objects of agricultural, production of forestry; if abandon arbitrarily burning; the meeting serious environment pollution utilizes living beings to burn in boiler, and the steam that produces is used for generating or steam supply; social benefit with energy savings, environmental contamination reduction also has good economic benefit.
At present, oneself boiler of the biological substance for combustion through releasing all is to research and develop in the technical foundation of coal-burning boiler.But, because biomass fuel moisture content is large, volatilization point is low, fugitive constituent is many, energy density is low, the boiler product of the biological substance for combustion of energy practical application all is again supporting gas-fired stove tool burning after employing fluidized bed combustion or the vaporization, this dual mode, system complex, investment is large, is difficult for realizing miniaturization, does not all reach desirable degree.
Summary of the invention
The purpose of this utility model provides a kind of sufficient combustion, and the thermal efficiency is high, and is simple to operate, the biomass fuel reverse combustion type boiler of environmental protection.
The purpose of this utility model realizes by following technical proposals:
Biomass fuel reverse combustion type boiler of the present utility model, comprise body of heater, be arranged on the exhaust opening on the body of heater, limnimeter, be arranged on the burner hearth in the body of heater, be arranged on the cooling fire grate of lower furnace portion and the water jacket that is arranged on the burner hearth periphery, water inlet pipe and outlet pipe, described exhaust opening is connected with air-introduced machine, it is characterized in that in described burner hearth, being provided with the water layer wall, described water layer wall is Z-shaped structure, and burner hearth is divided into top convection heat-exchange chamber and lower combustion chamber, and form the gas combustion chamber at the sidewall of combustion chamber, the top in its gas combustion chamber is connected with exhaust opening by convection heat-exchange chamber, the bottom in gas combustion chamber is connected with the lower end, combustion chamber, described water layer wall is connected with water jacket, and its air inlet is arranged on the sidewall of body of heater.
The indoor circulating water pipe that is provided with of described heat convection, its circulating water pipe is connected with water jacket.
Described burner hearth is oval burner hearth.
The utility model has the advantages that: simple in structure, the thermal efficiency is high: adopt the reverse combustion type gas collection and burn in one, realized that the cyclic formula of fuel in combustion chamber successively burns, its thermal efficiency is up to 86.51%.Environmental protection: smoke discharge amount 0.034kg/h, sulfur dioxide concentration 0.361g/m , can't see fume emission under the normality.It is the ideal device that utilizes biomass energy.
