The utility model comprises a furnace body with a heat insulation layer; a combustion pool is arranged at a lower part of the furnace body; the structural points are that: an internal wall of the combustion pool is a surface layer and grates of magnesium-carbon material; an air inlet hole is arranged at a lateral side of the combustion pool; an ash dropping groove is arranged at one end of the combustion pool and a push block connected with a motor by a cam mechanism is positioned at the other end of the combustion pool.
Description
Technical field:
The utility model relates to the improvement of solid biomass fuel boiler structure.
Background technology:
At present, still do not have a kind of boiler product of more satisfactory living beings class A fuel A on the domestic market, the design of various biomass fuel boilers is still continued to use the mode that the coal-burning boiler grate firing burns and is made, and does not have new quantum jump.The water content of biomass fuel is bigger, about 10-12%, be coal water content 4-8 doubly.Therefore, under the situation of using identical boiler, with being that fuel is compared with the coal, the exhaust gas volumn that with the biomass fuel is the fuel generation is 1-2 times of coal approximately.Biomass fuel density is less, when entering the body of heater internal combustion, can swim in the stove internal combustion along with water evaporates.
From the combustion process of fuel, most of biomass fuels are after drying, and volatile matter breaks away from parent fast and rapidly burns, and non-cohesive in the biomass fuel surface combustion, this and burning of coal mechanism are diverse.Fuel residue after volatile matter is overflowed is black or is coke shape kermesinus, does not see tangible flame, relies on the radiant heat smoulder of combustion cell inwall, and the tail-off time is also longer.Because usually all contain a large amount of alkali metal (potassium, sodium etc.) in the biomass fuel,, can not move continuously and the situation of intermittent combustion for a long time so fire grate coking, dross, disconnected flame all can appear in the boiler of burning-used biologic mass fuel at present; Need frequent blowing out scarfing cinder and igniting again.Therefore, biomass fuel boiler is extensively promoted the use of and has been subjected to serious restriction.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of noncoking in combustion process, non-nodulating are provided, but the solid biomass fuel boiler of long-time continuous operation.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises the body of heater with heat-insulation layer, and the bottom of body of heater is a combustion cell, the inwall of its structural feature combustion cell is the superficial layer of magnesium material with carbon element, the fire grate of magnesium material with carbon element, and the side of combustion cell is a fresh air inlet; One end of combustion cell is the ash-pit that falls, and the other end of combustion cell is provided with pushing block, and pushing block links to each other with motor by cam mechanism.
The beneficial effects of the utility model:
Because the inwall of combustion cell of the present utility model is the superficial layer of magnesium material with carbon element, the fire grate of magnesium material with carbon element, will form high temperature at the inwall of combustion cell, fuel residue after volatile matter is overflowed gasifies rapidly, slow after-flame, just avoided after blowing out, because of the cold coking of speed, dross, disconnected flame, guaranteed the long-time continuous operation of boiler of the present utility model.
The utility model can be widely used in the burning of solid biomass fuels such as stalk.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view (comprising the A-A cutaway view) of Fig. 1;
Fig. 3 is the left view (comprising the B-B cutaway view) of Fig. 1.
The specific embodiment:
The utility model comprises the body of heater 10 with heat-insulation layer 11, and the bottom of body of heater 10 is a combustion cell 23, and the inwall of combustion cell 23 is the superficial layer 20 of magnesium material with carbon element, the fire grate 25 of magnesium material with carbon element, and the side of combustion cell 23 is a fresh air inlet 21; One end of combustion cell 23 is the ash-pit 1 that falls, and the other end of combustion cell 23 is provided with pushing block 22, and pushing block 22 links to each other with motor by cam mechanism 24.
Be aditus laryngis 15 between the face arch 17 of body of heater 10, the rear arch 13, aditus laryngis 15 tops are combustion chamber 14; Combustion chamber 14 links to each other with the spiral feeder 19 of body of heater 10 outer material storing box 18 bottoms.
Like this, biomass fuel pellet relies on deadweight to glide by material storing box 18, deliver to the slope place 16 of aditus laryngis 15 face arch 17 uniformly through a plurality of spiral feeders 19, falls within the combustion cell 23 through aditus laryngis 15 again.The effect of aditus laryngis 15: the one, the high-temperature flue gas that produces when making the fuel combustion in the combustion cell 23 forms torch herein, lights the fresh fuel of whereabouts; The 2nd, make fresh fuel in the process that falls, form the fuel curtain, the flying dust that is mingled with in the flue gas of rising is bumped with fresh fuel, it is taken back in the combustion cell 23, to purify flue gas.
For the flue gas in the combustion chamber 14 is turned back through heat-exchange tube 3, making its heat is that water institute fully absorbs in the heat-exchange tube 3; The below of the top of heat-exchange tube 3 and adjacent heat-exchange tube 3 is a breaking part 6.
The below of combustion cell 23 is provided with bellows 26; The middle wind of pressing enters by the fresh air inlet 21 of bellows 26, combustion cell 23 sides.
Described magnesium material with carbon element is the prior art that colleague's those of ordinary skill is easily implemented, and promptly by behind scale graphite, magnesium, the alumina cement mixing, compacting, sintering form; For example, scale graphite can be 45%, magnesium is 35%, and all the other are alumina cement, and mixing, compacting, sintering form then.
Below in conjunction with a description of drawings use of the present utility model:
Biomass fuel pellet relies on deadweight to glide by material storing box 18, deliver to the slope place 16 of aditus laryngis 15 face arch 17 uniformly through a plurality of spiral feeders 19, falls within the combustion cell 23 through aditus laryngis 15 again.Under the effect of cam mechanism 24, pushing block 22 constantly moves reciprocatingly, and makes the fuel that falls into combustion cell 23 be covered with the bottom of combustion cell 23; At this moment, the middle wind of pressing enters in the combustion cell 23 by the fresh air inlet 21 of bellows 26, combustion cell 23 sides, biomass fuel pellet is acutely shaken, produce chemical reaction, swift and violent burning, produce a large amount of high-temperature flue gas and rising, enter combustion chamber 14, gas cleaning expansion chamber 9, heat-exchanging chamber 4 successively, at last to smokejack 5 discharges through aditus laryngis 15.
Fuel residue after volatile matter is overflowed is black or is coke shape kermesinus, relies on the slow afterburnt of radiant heat of combustion cell 23 inwalls, sends in the ash-pit 1.At this moment, for avoiding poly-group, coking, can not blow.
After water in upper drum 7, the lower drum 2 absorbed the heat of body of heater 10 internal combustion generation of the present utility model, output got final product.
