Description
Technical field
The present invention relates to a kind of energy-saving and emission-reduction multitubular boiler, belong to the hot water space heating boiler field with feed bin.
Background technology
At present, known numerous multitubular boiler generally is not with feed bin, can not make full use of the oxidation of water, combustion-supporting, catalytic action; Also do not have many water jacket series connection heating functions, heat exchanger effectiveness is low, and the volatile matter of being separated out in the combustion process, tar and pernicious gas can not get good treatment; Fuel combustion is insufficient; Flue dust can not effectively be handled, and not only wastes energy, and environment is had pollution.
Summary of the invention
The purpose of this invention is to provide a kind of energy-saving and emission-reduction multitubular boiler with feed bin, it adopts water jacket (water container) series connection, and the mode of vertical fire tube heating uses water as oxidant, and burn rate is high, and tangible low-carbon (LC) effect is arranged.The theory of combustion of the present invention is: it is carrier of energy that carbon or hydrogen can be considered, and energy can be changed between carbon and hydrogen." taking oxygen by force " reaction takes place in carbon or hydrocarbon and water in hot environment, promptly high-temperature steam and carbon or hydrocarbon carry out thermal chemical reaction, generate hydrogen-rich combustion gas.Absorb energy during water decomposition, oxidation of coal is to release energy, and energy is changed between carbon and hydrogen.Carbon and hydrogen need hot environment when carrying out power conversion, energy consumption only is used for the needed hot environment of maintaining heat chemical reaction.The present invention has made full use of the oxidation of water, combustion-supporting, catalytic action, and effects of energy saving and emission reduction is fairly obvious: improved fuel burn rate, enlarged the scope of application of fuel, the fuel that water content is big does not generally need preliminary treatment, can directly use.The coal smokeless combustion be can not only realize, water content big biomass fuel, house refuse and industrial or agricultural combustible waste material also are fit to as using energy source; Specific air consumption is few relatively, and the fire grate combustion intensity is low, has effectively reduced the discharging of dust; Adopt the positive and negative combustion system that combines, prolonged the thermal chemical reaction time of fuel, sufficient combustion has reduced tar and emission of harmful substances; Increase the series connection of heat exchange area and multi-cavity, improved the heat exchange effect, improved the thermal efficiency of boiler; Adopt vertical fire tube structure, the flow resistance of flue gas is little, can reduce the physical dimension of chimney.
The objective of the invention is to realize like this: the energy-saving and emission-reduction multitubular boiler of band feed bin; It is by: formations such as body of heater, heat exchanger, depositing dust storehouse is characterized in that: the band feed bin the energy-saving and emission-reduction multitubular boiler, be fixedly connected heat exchanger on its body of heater; Heat exchanger is being fixedly connected the depositing dust storehouse; Depositing dust is being fixedly connected exhanst gas outlet on the storehouse, is equipped with some fire tubes in body of heater, the heat exchanger, and makes body of heater, heat exchanger form independent water container respectively; Fire tube can be a single row configuration, also can be double or arranges structure more.A. heat exchanger by annular deashing cover, reinforced bell, feeding bin and depositing dust storehouse constitute, the depositing dust storehouse is provided with exhanst gas outlet, exhanst gas outlet can be connected with chimney or induced draught system.B. body of heater is by blanking bin, multi-functional fire door, ventilation duct, scarfing cinder fire door with draw grey fire door and constitute.C. multi-functional fire door, ventilation duct and draw and be equipped with adjustable valve and atomized water import on the grey fire door, the body of heater hypomere is provided with the turriform grate.
In order to improve the heat exchange effect, available pipeline is connected body of heater with heat exchanger in series.Regulate multi-functional fire door, ventilation duct and draw the valve on the grey fire door, can realize the big fire of boiler, little fire is banked up a fire or requirement on fire fast.Open annular deashing and cover the cleaning ash disposal that can be used for fire tube.
The present invention can use chimney gravity-flow ventilation burning, also can use the burning of air blast blast roasting or air-introduced machine air inducing, can also chimney, air blast and air-introduced machine use simultaneously.Be equipped with corresponding machinery and electrical equipment and can realize automatic charging, the break of boiler fall ash and the big or small adjustment of boiler output, need not the special messenger keep an eye on.

The specific embodiment
Fig. 1 is the structural representation that the present invention executes example.Light and light a fire, its method is identical with general vertical boiler.
Light and once fill it up with fuel after lighting a fire, build reinforced bell 3.
Instructions for use according to fuel used difference and boiler output size; Regulate multi-functional fire door 9, ventilation duct 10 respectively and draw the valve on the grey fire door 13; And the water content size adjustment atomized droplet water yield of based on fuel, make the stove internal combustion be in needed fired state.Fuel begins drying and dehydrating from top to bottom; Separate out volatile matter, generate fixed carbon, coke tar cracking; Water heats up and is high-temperature steam and carbon or hydrocarbon generation thermal chemical reaction; Make full use of the oxidation of steam, combustion-supporting and catalytic action generation hydrogen-rich combustion gas, combustion gas flows downward and meets oxygen burning formation flame, and flame or flue gas be recirculated water in body of heater fire tube 19, heat exchanger fire tube 7 mobile also heating furnaces.Gas is by flowing shown in the arrow among the figure in the stove, and flue gas is discharged by exhanst gas outlet 1 behind the gravity depositing dust.The different and size of exerting oneself according to fuel used added primary fuel in denumerable hour or tens of hours.
The present invention has: simple in structure, be easy to processing, low cost of manufacture; Easy to operate, easy to utilize; Adaptability to fuel is strong, and fuel source is extensive, and fuel price is low, economic operating cost.
Because energy-output ratio increases year by year, harmful substance excessive emissions, unusual weather conditions, harm humans existence.So each state all making great efforts exploitation energy-saving and emission-reduction product, reduces carbon emission, the reply climate change.Therefore, the present invention has good economic benefits and social benefit.
