Abstract
The invention discloses a biomass direct combustion furnace and relates to a household solid fuel furnace. A furnace body comprises an inner barrel and an outer barrel; by means of a draught fan, air is fed to an air pre-heating chamber through a primary air delivery pipe; primary air annular air inflow air holes are formed in the lower portion of the inner barrel; and secondary air annular air inflow air holes are formed in the upper portion of the inner barrel. A direct combustion manner is adopted for the biomass direct combustion furnace, the structure is simple, the combustion efficiency is high, dense smoke is avoided, the whole furnace body is moderate in size, the appearance is simple, and the biomass direct combustion furnace is especially suitable for being applied and popularized in the vast rural areas and the low-carbon gens.
Description
Technical field
The present invention relates to a kind of biomass direct-fired furnace, particularly a kind of high-efficiency energy-saving biomass direct-combustion furnace.
Background technology
At present, in vast rural area, biomass combustion is still as main cooking mode, and traditional cooking stove efficiency is the lowest, the biomass resource that waste is valuable.Because efficiency of combustion is low, during burning, cigarette is very big, the health of serious harm numerous people and pollute air.At present, there are a lot of entity and individual to devise Wood-saving stove, achieve certain effect, but still there is a lot of problem.Such as, the excess air coefficient of second-time burning is excessive, and body of heater is bulky, and the cost of production is high.
Summary of the invention
The present invention is directed to the problem that current wood stove exists, around the bare bones of burning, burning time, air secondary preheating and integrated air excess coefficient thereof, wood stove is optimized design.
The technical solution adopted for the present invention to solve the technical problems is: a kind of biomass direct-fired furnace, including body of heater, aerator, body of heater includes inner core, urceolus, and inner tube wall is provided with air inlet, and blower fan is positioned on body of heater.
Inner core is combustor, has space between inner core and urceolus, and this space just constitutes the annular air preheating chamber that a bottom communicates.Air is to be connected to inner tank theca by a primary air conveying pipe through urceolus, blows air into the annular air preheating chamber between inner core and urceolus by the blower fan on primary air conveying pipe.Once air circular air inlet hole, inner core bottom, auxiliary air circular air inlet hole is arranged at top.Upper and lower two parts are divided in the auxiliary air circular air inlet hole on inner core top.The axis direction in the auxiliary air circular air inlet hole of the latter half is angled downward from horizontal, can be blown into inside inner core by the air of preheating, in the burning incipient stage filling it up with biomass fuel, it is provided that primary air and the effect having secondary air supply concurrently.The axis direction in the auxiliary air circular air inlet hole of top half is horizontal direction or upward from horizontal, provides secondary combustion-supporting air for imperfect combustion combustion gas so that it is fully burn.The primary air circular air inlet hole of inner core bottom provides primary air for burning.
The fresh air inlet quantity on inner core top is 6 to 12 times of the fresh air inlet quantity of inner core bottom.So can make the incomplete flue gas of primary combustion, burn completely at auxiliary air air inlet.The inner core of frustum of a cone form can make combustion gas collect on inner core top, concentrates and mixes the effect completely that reaches to burn with the auxiliary air on top.Annular firestopping ring can make the hot combustion gas around the flow direction guide vertically upward, and the most heated cooker periphery absorbs heat, improves the utilization ratio of heat.
Proving through test of many times, use 1000 grams of firewoods can do 4 general home cookings, burn open the water of 5 kilograms of a kettle. the present invention has compact conformation, elegant in appearance, burning is abundant, the thermal efficiency is high, and environmental pollution is few and production cost is low.It is particularly suitable in vast rural area and the popularization and application of low-carbon (LC) family.

Detailed description of the invention
Inner core is combustor, has space between inner core and urceolus, and this space just constitutes the annular air preheating chamber that a bottom communicates.The air preheating chamber communicated bottom this has two effects, and an air being to provide preheating to primary combustion and second-time burning, one is as thermal insulation layer.The annular air preliminary heating zone that air is blown between inner core and urceolus by blower fan by primary air conveying pipe.Once burn annular fresh air inlet in inner core bottom, and second-time burning circular air inlet hole is arranged at top.Inner core is that truncated cone shape, beneficially combustion gas are collected to inner core top, is sufficiently mixed with the preheated air of second-time burning circular air inlet mouth, reaches clean-burning effect.
Upper and lower two parts are divided in the circular air inlet hole on inner core top.The auxiliary air circular air inlet axially bored line direction of the latter half is angled downward from horizontal, can be blown inside inner core by the air of preheating, and being depleted to this period of time of half storehouse from buying securities with all one's capital for fuel provides primary air and have the effect of secondary air supply concurrently.The auxiliary air circular air inlet axially bored line direction of top half is level or upward from horizontal, provides secondary combustion-supporting air for imperfect combustion rising flue gas so that it is fully burn.Circular air inlet hole of inner core bottom provides primary air for burning.The auxiliary air fresh air inlet quantity on inner core top is 6 to 12 times of the primary air fresh air inlet quantity of inner core bottom.The incomplete flue gas of primary combustion so can be made to burn completely.Annular firestopping ring can make the hot combustion gas around the flow direction guide vertically upward, and the most heated cooker periphery absorbs heat, improves the utilization ratio of heat.
