Description
Technical field
The invention belongs to the technical field of burner, particularly relate to feeding biological particles burner under a kind of benzvalene form.
Background technology
At present, coal-fired combusting device, oil burner, gas burner are popularized, yet, owing to coal, oil, gas are the non-renewable energy, poor day by day along with coal, oil, the gas energy receives much concern as the development and use of the biomass energy of the fourth-largest energy.
China is a large agricultural country, biomass energy is very abundant, biomass energy is the main energy sources in rural area, now, the rural area agricultural crop straw generally is to return the field by directly burning in the field, perhaps burns kitchen range, heats up water, cooks, warms oneself with it, utilize situation to fall behind, pollute greatly, influence environment, also cause the waste of resource simultaneously.The stalk in China rural area is important biomass resource, and the straw burning value is about 50% of standard coal.China can produce more than 600,000,000 ton of agricultural crop straw every year, as all being used for burning, can amount to the calorific value of about 300,000,000 tons of standard coals.It has good in the coal effect.Sulfur content, the nitrogen content of living beings is low, generate in the combustion process SOx, NOx are less, pollute less.Because biomass material is cheap, the biomass molding fuel that produces also has bigger price advantage than present surging raw coal and moulded coal, is beneficial to and promotes the use of.Biomass energy is a regenerative resource, and in today of energy worsening shortages, the development and use biomass energy has great energy strategy meaning.
Living beings are meant the various organisms that form by photosynthesis, comprise all animals and plants and microorganism.And so-called biomass energy promptly is the energy of carrier with living beings.It derives from the photosynthesis of green plants directly or indirectly, can be converted into solid-state, liquid state and fuel gas, is a kind of regenerative resource, and at present, a lot of countries are at present all in active research and development and use biomass energy.The biological particles material generally is to be formed through pulverizing compacting by agricultural crop straw.Present existing biomass burner, the boiler that is used for heat supply, heating more, the burning form of its boiler is divided into fluidized bed combustion and layer combustion, layer combustion is common combustion system, the fire grate of grate firing boiler mainly contains fixed grate, vibrating-grate stoker and traveling-grate stoker, its complex structure, low, the performance less stable of efficiency of combustion.
Feeding biological particles burner under the general benzvalene form comprises feed system, air feed system, burning stone or metal plate for standing a stove on as a precaution against fire; Feed system comprises the material pipe, expects in the pipe feeding screw to be installed, the material pipe connects with feeding port and is connected, drive feeding screw swivel feeding in the material pipe by reducing motor, the feeding port top connects with burning stone or metal plate for standing a stove on as a precaution against fire below and is connected, air feed system comprises blower fan, ajutage, blower fan is connected with air compartment, is covered with passage on the burning stone or metal plate for standing a stove on as a precaution against fire wall, and biological particles is the dishful burning in the burning stone or metal plate for standing a stove on as a precaution against fire.Feeding biological particles burner belongs to layer combustion under the benzvalene form, it is simple in structure, but because the ash fusion point of biomass fuel is lower, surpass 850 ℃ and just be easy to slagging scorification, in order to guarantee the not slagging scorification of burning, the stone or metal plate for standing a stove on as a precaution against fire that benzvalene form can only be burnt is designed to less form, and generally its diameter is not more than 25 centimetres, thereby has limited feeding biological particles burner applying on boiler under the benzvalene form.
Summary of the invention
The present invention is in order to solve the technical problem that exists in the above-mentioned technology, and endless belt-shaped burning, the environment protecting that provide a kind of efficiency of combustion height, forms certain width be good, can be to feeding biological particles burner under the benzvalene form of relatively large boiler heating.
The present invention for the technical scheme that solves the technical problem that exists in the above-mentioned technology and take is:
Feeding biological particles burner under a kind of benzvalene form of the present invention, it comprises pay-off, air supply device, burning stone or metal plate for standing a stove on as a precaution against fire; Pay-off comprises feed pipe, feeding screw, feeding port; Feeding screw is installed in the feed pipe, and feed pipe connects with feeding port and is connected, and drives feeding screw swivel feeding in feed pipe by reducing motor, and the feeding port top connects with burning stone or metal plate for standing a stove on as a precaution against fire below and is connected; Air supply device comprises pressure fan, air compartment, and pressure fan connects with air compartment and is connected; Air compartment is arranged on the exterior circumferential of burning stone or metal plate for standing a stove on as a precaution against fire and feeding port; The ventilation strip that burning stone or metal plate for standing a stove on as a precaution against fire top edges is formed with certain width, is made up of most passages; Also comprise being formed on burning stone or metal plate for standing a stove on as a precaution against fire central authorities, and be installed in the agitating device of feeding port and air compartment central authorities by axle sleeve; Because burning stone or metal plate for standing a stove on as a precaution against fire top edges is formed with certain width, by the ventilation strip that most passages are formed, make the endless belt-shaped burning of the burning formation certain width of biological particles burner; The certain width that burning stone or metal plate for standing a stove on as a precaution against fire top edges forms, by the ventilation strip that most passages are formed, its width is 20MM-120MM; Agitating device comprises that an end is installed in feeding port and air compartment central authorities by axle sleeve, and the below has the shaft of bevel reduction gear set and is fixed on the puddler of shaft upper end; The puddler that is fixed on the shaft upper end is certain inclination angle upward and is provided with, and its quantity is single and a plurality of; Below feeding port, be formed with more than one equalizing pressure hole.
Advantage and good effect that the present invention has are: feeding biological particles burner under the benzvalene form of the present invention, burner adopts endless belt-shaped burning, can make ignition temperature not slagging scorification more than 1000 ℃, make fuel in a short period of time at the whole after-flames in combustion chamber, improved the efficiency of combustion of fuel greatly.The design of agitator arm at a slow speed in the middle of the burner makes fuel carry out evenly sufficient endless belt-shaped burning on the one hand, makes fuel that the precombustion gasification is arranged on the other hand, produces a large amount of CO, forms second-time burning above burner, has assisted endless belt-shaped combustion system.Greatly reduce boiler soot emission concentration, clean environment firendly.Adopted endless belt-shaped combustion system, made burner not be subjected to size restrictions, be applied on the big arcola and all can.Based Intelligent Control is simple, and economical operation is safe and reliable.Burner power output size is complete, can satisfy different clients' differentiated demand.
