Description
Technical field
The present invention relates to Small Combustion device field more particularly to a kind of grate-firing combustion devices of vertical lift, realize simultaneous
Lamps structure is compact, metal consumption is few, adjusting is simple, easy burn-out, thermic load be not adaptable and the features such as heat loss is smaller
Layer combustion burning.
Background technology
Layer combustion burning is a kind of basic coal-fired mode, and burner is known as grate furnace.Grate furnace can be divided into handwarmer,
Chain furnace back and forth pushes stove, vibration stove and spreader stoker boiler.Handwarmer is although simple in structure, cheap, but its coal, puts a chimney on the stove and make the fire draw
It is intended to complete by manual operations with ash disposal work.To reduce labor intensity, grate firing boiler is developed into mobile grate
Chain furnace.Its fire grate moves in the horizontal direction, and coal is moved from stokehold to stove rear direction therewith, is burnt down substantially when after arrival stove,
Remaining lime-ash drains into ash bucket.But since the process needs air zoning, every section of air-supply to need individually to adjust air output to match difference
Air capacity needed for combustion phases.Therefore, the structure of chain furnace and its adjusting are complex, and since fire grate moves horizontally,
Its floor space is larger.Compared with above-mentioned chain furnace, it is reciprocal push the mobile grate of stove be it is inclined, fuel with fire grate shifting
It is dynamic that rolling, stirring and drying occurs, to make burning more ingredient.Its structure is more simple compared with chain furnace, and metal consumption is also few,
Burning suitable for domestic waste；But its fire grate segment cooling it is poor, be easy to burn out, adapt to thermic load variation ability compared with
Difference, and also need larger floor space.The fire grate of vibration stove be equally from stokehold to stove rear-inclined, and by electric power generation shake
It is dynamic.Fuel is tossed under the vibration of fire grate, from stokehold to stove after tumbling motion, until after-flame.Vibrating-grate stoker uses water cooling, drop
Low fire grate operating temperature, increases the fire grate service life.But its occupation of land is still larger, and due to generating vibration, structure is more complex and holds
Easily it is broken.To improve ignition condition, air zoning is avoided, spreader stoker boiler is commonly used in engineering.Pass through machinery, the modes such as wind-force
Coal is thrown into stove, existing suspension combustion in stove, and has layer combustion burning.Slightly larger ickings has little time after-flame and just flies out burner hearth, because
This unburned carbon in flue dust is higher, and heat loss is larger.
The above analysis, current grate-firing combustion device include mainly there are different degrees of technological deficiency：Handwarmer
Low mechanization degree, the structure of chain furnace with adjust complicated and take up a large area, it is reciprocal to push the easy burn-out of stove and heat negative
Lotus adaptability is poor, the easy fracture of vibration stove and complicated, and the heat loss of spreader stoker boiler is big.The above equal volume of the type of furnace is huge
Greatly, inconvenient, to the bad adaptability of load variations.
Invention content
In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to develop it is a kind of have it is compact-sized,
