Biomass compacted granules direct combustion normal-pressure hot-water boiler

Technical field

This patent is related to a kind of Thermal Equipment, in particulars relate to one kind and does fuel with biomass compacted granules, and the biomass compacted granules direct combustion normal-pressure hot-water boiler that atmospheric hot-water provides the user warming or production heat service is produced by direct combustion type.

Background technology

AND ENERGY RESOURCES CONSUMPTION IN CHINA total amount nearly 2,500,000,000 tons of marks coal, as the energy resource consumption big country for occupying second place of the world, and the energy that China consumes at present, the overwhelming majority is provided by burning coal mode.Burning coal, can not only give off the harmful greenhouse gases such as a large amount of sulfur dioxide, carbon dioxide, and can give off a large amount of dust particle, and the PM2.5 molecules particularly discharged can all constitute high risks to atmospheric environment and human body health.

China is agriculture, production of forestry big country, and year biomass resource generation total amount is up to more than 5,000,000,000 tons of mark coals, with the resources advantage large-scale developed and utilized.Under national energy strategic guidance, in the case where prevention and control of air pollution action is actuated, China's biomass energy exploitation industry development is very swift and violent, and many advanced and mature conversion technology of biomass energy and special technology equipments are all widely applied successively.Wherein biomass solid shaping technology, biomass material compacting can be solidified into combustible granules, the technical barriers such as seasonal strong, decentralization high, water content is big, elongated loose, the inconvenience collection transport storage of volume of biomass material itself presence are preferably solved, are that extensive steady in a long-term apply creates good technical foundation condition.Recent years, time limit is all made in succession and eliminates the prevention and control of air pollution action plan torn open and remove less than 10 tons coal-burning boilers in many big or middle cities, the biomass boiler for making it possible to substitute coal-burning boiler, do fuel with biomass compacted granules arises at the historic moment development rapidly, and considerable influence is generated in conversion technology of biomass energy field.

The biomass boiler put on market at present, the overwhelming majority is on the basis of former coal-burning boiler, used by certain technological transformation aftershaping, all by the larger limitation of original structure, therefore existing biomass boiler all has some technical problems to varying degrees in terms of fuel addition manner, ventilation oxygen supply approach, combustion-chamber shape volume.It is mainly manifested in following three aspect.

1st, some biomass boilers have continued to use the filling method of coal-burning boiler, and directly fuel is added to combustion chamber using from fire door；But because biomass fuel phosphorus content is low, easily burn, need frequently to open fire door addition fuel, often produce the technical problems such as chamber temperature is unstable, fugitive constituent precipitation is insufficient, and open fire door in burning, not only easily cause flue gas to be escaped from fire door, and reduce boiler thermal output.

2nd, some biomass boilers have continued to use the chamber structure shape, volume size and ventilation oxygen supply approach of coal-burning boiler；But due to the physical property feature such as biomass fuel has that volatile content is big, component is complicated, the precipitation time is slow, enough combustion space and burning time are needed during burning, certain infiltration flow strength and appropriate stagnant control ability are needed during ventilation oxygen supply.The combustion chamber volume of coal-burning boiler is less than normal, and planform is simple, typically all uses bottom-up direct method of ventilation；This structure type is used for biomass fuel combustion, and often producing insufficient biomass fuel combustion, fugitive constituent and solid-state carbon granules, easily discharge, inhalable particles discharge the technical quality problems such as exceeded with the wind.

3rd, the existing biomass boiler overwhelming majority takes directly discharge flue gas, is configured without flue gas separating purifying device, generally existing inhalable particles discharge excessive problem.Biomass boiler does fuel using biomass compacted granules, although not producing the pernicious gases such as sulfur dioxide, control techniques is efficiently separated but if not taking discharge flue gas, a large amount of inhalable particles are still had, PM2.5 molecule discharge beyond standards are particularly had, atmospheric environment is polluted.

This patent is on the basis of the existing biomass boiler Shortcomings of China and weakness is conscientiously researched and analysed, according to the combustion characteristics of biomass compacted granules, targetedly form is added in fuel, air-supply oxygen supplying control method, combustion chamber direct combustion environmental condition, multinomial structure innovation technical measures are taken on the key core technology contents such as isolation of purified measure, research and design goes out one kind and does fuel using biomass compacted granules, with spiral continuous and quantitative feed, Double layer spiral flow has control to blow, the aerobic abundant direct combustion of fuel, flue gas intercepts the biomass compacted granules direct combustion normal-pressure hot-water boiler of the operation functions such as isolation of purified, coal-burning boiler can be substituted and meet enterprise of the northern area away from heating network, market, office, school, the production and living such as residential building place warming needs, also spray painting is adapted to, food, chemical industry, the technical conditions requirement of the industry productions such as medicine heat.
