Description
Technical field
The present invention relates to the technical field of combustion furnace, specifically a kind of energy-saving free of smoke burning stove.
Background technology
The veneer of timber is the raw material for producing the wood-based plates such as glued board, core-board, thick china, and veneer is generally to use log
Rotary-cut is formed.Because the veneer that rotary-cut goes out contains large quantity of moisture, so needing to be used for producing people after it being dried processing
Make plate.The traditional drying mode of wood single-plate is that nature dries, and the process duration length of this method is, it is necessary to dry suitably
Natural environment and spacious site condition, are easily influenceed by weather environment, it is difficult to applied to industrialized large-scale production.In order to
Overcome the shortcoming that nature dries, people, which have invented baking oven, drying room or special drying unit, is dried, and plank is uniformly distributed
In baking oven or drying room, and keep certain gap, being heated by electrical heating or fuel, so that plank is dried place
Reason.At present, the heat that most of wood producing producers produce after being all by the use of useless plate and wood skin as fuel combustion is to timber list
Plate is dried, that is, needs a kind of hot-blast stove of burning fuel.Drying agricultural byproducts are also the same, are required for a kind of burning fuel
Hot-blast stove, for drying agricultural byproducts hot blast is provided.
However, the useless plate and wood skin of the Combustion of Hot Air Furnace that in the market is used all are dry, water content will fire higher than 20%
Burn insufficient, produce black smoke, plate and wood skin could meet the baking of wood single-plate to the shortage of heat of generation, it is necessary to which substantial amounts of drying is given up
Dry demand.But in overcast and rainy drying fuel, i.e., useless plate and wood skin under-reserve, it is impossible to utilize the useless plate and wood of water content greatly
Skin is dried as fuel to wood single-plate.Virtually add the workload for shining or drying useless plate and wood skin.
The content of the invention
It is an object of the invention to provide a kind of energy-saving free of smoke burning stove, the burning stove may be mounted in hot-blast stove, as
The combustion chamber of hot-blast stove, the combustion furnace can burn fuel of the water content more than 35%.
The technical solution adopted by the present invention is：
A kind of combustion chamber in energy-saving free of smoke burning stove, including stove, ventilation duct and air blower, described stove is in up-small and down-big
Taper, the side's of being taper or cone；The gradient of combustion chamber is 20 ° -35 °；Combustion chamber bottom is dust collection chamber；Ventilation duct is installed

It is logical；The air vent connected with combustion chamber is provided with ventilation duct；The ventilation duct of bottom is connected with air blower；Air blower rouses air
After the ventilation duct for entering bottom, the connecting tube between the ventilation duct in intermediate layer and the ventilation duct of bottom enters the ventilation in intermediate layer
Pipe, then connecting tube between the ventilation duct in intermediate layer and the ventilation duct of top layer enter the ventilation duct of top layer.Three layers of ventilation duct are in
Arranged parallel.Connecting tube caliber between the ventilation duct in intermediate layer and the ventilation duct of top layer is more than the ventilation duct and bottom in intermediate layer
Ventilation duct between connecting tube caliber.The caliber of connecting tube between the ventilation duct in intermediate layer and the ventilation duct of top layer and centre
The caliber of the ventilation duct of layer is consistent；The ventilation of connecting tube caliber and bottom between the ventilation duct in intermediate layer and the ventilation duct of bottom
Pipe caliber is consistent.
It is 20 centimetres that the top bore of described combustion chamber, which is more than,.
The height of described stove is less than 70 centimetres.
The aperture of the air vent on three layers of ventilation duct is respectively 3-4.5 millimeters, 3-4.5 millimeters and 4.5-5.5 from top to bottom
Millimeter.
The pitch-row of air vent on the ventilation duct of top layer is the air vent on 2.5-3.5 centimetres, the ventilation duct in intermediate layer
Pitch-row is that the pitch-row of the air vent on 4-5.5 centimetres, the ventilation duct of bottom is 7-8.5 centimetres.Three layers of ventilation duct from top to bottom
Caliber is sequentially reduced, and the ventilation bore of such as top layer is 6.5 centimetres, and the ventilation bore in intermediate layer is 6 centimetres, bottom it is logical
Airduct internal diameter is 5.5 centimetres.
The energy-saving free of smoke burning stove of the present invention is simple in construction, sets ingenious, may be mounted in hot-blast stove, be used as hot-blast stove
Combustion chamber, can also as other functions burning stove.The fuel combustion of energy-saving free of smoke burning stove fully, is seldom produced black
Cigarette.Energy-saving free of smoke of the present invention burning stove uses biomass fuel, such as bark, wood fragments, stalk, weeds can, burning is abundant,
When having stove 50% drying fuel of inner volume in energy-saving free of smoke burning stove, allow after temperature stabilization, moisture content 50%- can be added
70% fuel, can also burn the weeds that need not be dried just cut down from mountain or fresh tree branches and leaves enter Indoor Combustion of burning, stove
Temperature in wall is up to more than 1200 DEG C.
