Description
Technical field
The utility model belongs to boiler technology field, and in particular to a kind of straw bundle burning normal-pressure hot-water boiler.
Background technique
As haze phenomenon occurs frequently in China's air, the issuing and implementation of the newest environmental law of country, the environmental consciousness of people is not
Disconnected enhancing, how on source contaminant restraining discharge is at the most important thing, finding a kind of reliable energy of cleaning, oneself is extremely urgent,
Biomass fuel has volatilization high as renewable energy, and easy firing, content of ashes is low, SO in product after burningXAnd NOXEtc. having
Evil gas is less, wherein a distinguishing feature is CO2Zero-emission.Therefore, biomass energy application obtains in worldwide
Pay attention to extensively.And biomass fuel burning technology is presently the most mature biomass application technology.Large quantities of biomass boilers are met the tendency of
And it gives birth to.
Existing biomass boiler fuel be all straw collecting become square or circle pouch-type, transport back processing carry out briquetting or
Burn again after being pressed into graininess, fuel cost double it is above, it is very uneconomical.Since the moisture before stalk processing is general
Up to 40% or so, directly burning will cause burning and be not thorough, and be difficult after-flame, efficiency of combustion is low.If bundling stalk can be made to exist
It is dry before burning, moisture is down to 25% hereinafter, then bundled stalk is sent directly into furnace and burns, then this mode is most to pass through
Ji.
Summary of the invention
The purpose of the utility model is to provide a kind of straw bundles to burn normal-pressure hot-water boiler, thoroughly solves existing biomass normal pressure
Defect and deficiency present on hot-water boiler combustion technology, the utility model structure is simple, and rationally, stalk does not have to deep add for design
Work realizes save the cost, easy to use.
To achieve the above object, the technical solution adopted in the utility model is a kind of straw bundle burning normal-pressure hot-water boiler, packet
It includes: boiler body, pedestal, feeding device, combustion zone, water-cooled grate, smoke inlet, gas reversal chamber, threaded flue and smoke outlet,
Boiler body is fixed on pedestal, and feeding device is arranged in furnace body on the pedestal before combustion zone, and with combustion zone phase
Cooperate, threaded flue, smoke inlet, gas reversal chamber and smoke outlet are fixedly installed above combustion zone, water is arranged in threaded flue periphery
Chamber, the feeding device include: hydraulic gear pump, hydraulic cylinder, feeding platform and scraping wings, and the combustion zone includes: straw
Stalk pretreating zone, straw burning area, flue gas pooling zone and fuel gas buring area, it is fixed between flue gas pooling zone and fuel gas buring area
Combustion gas spout is set, water-cooled grate is fixedly installed below combustion zone.
Air compartment and slag removal tank are provided in the boiler foundation, air distribution outlet, the combustion gas nozzle is arranged in straw burning area
It is provided with tuyere and air port.
Swirl vane is provided in the air port of the combustion gas nozzle setting.
Water inlet pipe and outlet pipe are provided on the furnace body.
The utility model is matched due to being provided with feeding device on the pedestal of furnace body front end with the intracorporal combustion zone of furnace,
Hydraulic cylinder drives stalk pretreatment area pre-heating drying of the scraping wings by bundled stalk through feeding platform push-in combustion zone, through furnace
High-temperature flue gas in thorax enters combustion zone after inversely drying and burns, and the combustion gas of generation enters combustion through spout in flue gas pooling zone
Combustion chamber, last flue gas are discharged again through smoke inlet, threaded flue, gas reversal chamber, then after threaded flue from smoke outlet
Outside furnace, the straw ash after burning enters slag removal tank and removes outside furnace.
The utility model is using the above structure, producible to have the beneficial effect that
1, stalk is without being processed into particle or briquetting, can direct burning straw, intermediate processing link is eliminated, thus significantly
Reduce operating cost
2, it is inversely dried, can be dried through the bundling stalk for being 40% or so to moisture content using burner hearth high-temperature flue gas,
The moisture in stalk is reduced, is conducive to stalk in the burning of combustion zone.
3, the higher flue gas of moisture content that dry stalk generates enters burner hearth, adds the secondary wind action in burner hearth side,
Be conducive to control fire box temperature, reduce NOXGeneration.
4, using water-cooled grate, be conducive to control stalk combustion temperature, prevent stalk coking；Along with the big packet fuel of stalk
Density is small, and the ash fusion point of straw ash is not achieved in ignition temperature, so noncoking when burning.
5, using threaded flue, reinforce the heat transfer effect of water and flue gas.
6, combustion gas spout is used behind flue gas pooling zone, has secondary tuyere and overfiren air port in combustion gas spout, two
It is equipped with swirl vane in secondary air port, Secondary Air is made to rotate into combustion gas spout, the fuel gas not burnt in flue gas pooling zone is logical
It when crossing combustion gas spout, burns again under the action of Secondary Air, improves the thermal efficiency, reached energy-saving and environment-friendly effect.
The utility model is described in further detail with reference to the accompanying drawing.
