Specific embodiment
A kind of non-forming biomass combustion device of the present invention is mainly by source material delivery system and two part of combustion chamber
Composition.Source material delivery system is made of level-one helixes feed equipment 16, intermediate seal feed bin 15 and deuterostrophies charging gear 13,
Level-one helixes feed equipment 16 is connected with intermediate seal feed bin 15, and the spray for preventing biomass from strile-bacing is equipped in intermediate seal feed bin 15
The lower part of water installations 14, intermediate seal feed bin 15 is connected with deuterostrophies charging gear 13, deuterostrophies charging gear 13 and combustion
Room 10 is burnt directly to communicate.The position that deuterostrophies charging gear 13 is connected with combustion chamber 10, which is equipped with, prevents the water-cooled jacket 12 that strile-backs.Combustion
The fire grate for burning room is made of the composite grate that the water-cooled grate 9 being in tilted layout is formed with reciprocal grate 7.Wherein water-cooled grate is
The patent of authorization, the patent No.: ZL200710012779.9, reciprocal grate 7 are connected with its underpart slag remover 6, the chimney arch 8 of combustion chamber
And interior wall 2 is made by refractory material, exterior wall 1 is made by thermal insulation material, arranges that fuel blows hot-air on oriented fire grate on chimney arch 8
Combustion air heats and supply air system 5, and gas fume of combustion chamber outlet 11, high temperature flue 4 and high-temperature flue gas are furnished in combustion chamber
Outlet 3.
The combustion air heating and supply air system 5, is located on arch, and there are two types of cold air heating methods, one is
Cold air is directly mixed with the high-temperature flue gas of combustion chamber, cold air is directly heated or the high temperature air containing high-temperature flue gas；Such as
Figure two, which show to mix using the high-temperature flue gas of combustion chamber with cold air, directly heats cold air；Another way is to utilize burning
The high temperature of room is externally heated by the pipeline for conveying combustion air, so that the air of the inside is heated into hot-air.The technology
It can be used for the burning of other fuel.It is another as shown in Figure 3, using combustion chamber heat will outside air supply tube heating to
By the method for the cold air heating in pipe.
Working principle is as follows: it will be put into the hopper of level-one screw(-type) feeder 16 by broken tangerine bar biomass straw bag,
Through being sent into the water-cooled grate 9 in combustion chamber 10 through deuterostrophies conveying batcher 13 in helical feed to intermediate seal feed bin 15
On, it is paved with Ignition after tangerine bar on water-cooled grate, after igniting, is heated and the system that blows according to the combustion case of fire from combustion air
5 air-supply of system, it is ensured that in wind to fire, air heating is controlled with the unlatching quantity of supply air system 5 and position according to combustion case, is fired
Wind is fired during burning based on supply air system 5, under water-cooled grate 9 and reciprocal grate 7 is auxiliary wind, fuel on fire grate to wind
It is more, wind is helped to paving when flame is more prosperous, remaining situation does not give wind, prevents the cold air under fire grate to be directly blown into combustion chamber, causes nitrogen
Oxide increases.Fire get up after, through feeding system continuous-feeding, the fuel not burnt falls on subsequent afterflame on reciprocal grate
It burns, reciprocal grate turns over the fuel not burnt up and down and smashes, and comes into full contact with the high temperature air on unburned fuel and top, simultaneously
It falls on ashes on fire grate, prevents it from hindering burning.The ashes of after-flame are sent in slag remover 6 by reciprocal grate, are removed and are arrived outside.Combustion
The high-temperature flue gas generated is burnt through exhanst gas outlet 11, and exhaust gases passes 4 are discharged through exhanst gas outlet 3.Supply air system 5 is sent through air blower
Cold air, in exhaust gases passes 4, using siphon principle, by high-temperature flue gas suction draft pipe, by the cold sky in air supply tube
Gas Hybrid Heating, hot wind blow to the surface of fuel from arch, carry out combustion reaction.When blowing out, level-one screw(-type) feeder 16 stops
Feed, deuterostrophies batcher 13 has sent the fuel in intermediate seal feed bin 15 can blowing out.If the material of intermediate bunker
Clean appearance tempering smoke conditions are not sent, starting water injector 14 goes out fire-fighting.
