The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment:
Like Fig. 1, horizontal biomass fuel boiler shown in Figure 2, comprise the sealing burner hearth 5 that furnace wall 4 surrounds into, be provided with fire grate 13 in the said burner hearth 5, said fire grate 13 belows are connected with some lower feeding spiral feed systems 2.
Said fire grate 13 is provided with some fine and closely woven through holes, and said fire grate 13 middle parts are given prominence to and are 15 ° to 30 ° inclination with two ends, and said fire grate 13 middle parts are provided with the feeding cylinder 20 that runs through fire grate 13, and the top of said feeding cylinder 20 contacts with fire grate 13.Fire grate 13 is corresponding to be watched formula spiral feed system 2 under each and arranges, thus make fuel more equably cloth expect in the whole burner hearth 5 that the air that fine and closely woven through hole can bring through air blast 1 makes efficiency of combustion higher, more abundant.
Said lower feeding spiral feed system 2 comprises conveying worm 15, is arranged on the feed hopper 18 on the conveying worm 15; Said feed hopper 18 is arranged on outside the burner hearth 5; Be provided with in the said conveying worm 15 and stir plate 16; Said stirring plate 16 be arranged on feeding cylinder 20 under, said feeding cylinder 20 bottoms and conveying worm 15 internal communication.Lower feeding spiral feed system 2 is fixing with ground 14 through pin circle 17; After biomass granule fuel gets into conveying worm 15 through feed hopper 18; Under the push effect of the blade of conveying worm 15; Fuel is transported to 16 last times of stirring plate of feeding cylinder 20 belows, under the push effect of radially running, forms continuous feed process from bottom to top.On fuel, move past in the journey, the fuel that overflows feeding cylinder 20 tops begins fire grate 13 uniform distributions to both sides, arranges in burner hearth 5 tilt owing to have the fire grate 13 of fine and closely woven through hole; Under the gravity effect, fuel slippage is good, and the fuel distribution on the fire grate 13 also relatively evenly; Feeding cylinder 20 is positioned at fire grate 13 belows, does not receive the influence of high-temperature flue gas, in burner hearth 5, install radiant wall 21 additional after; Increased radiant heat, made that the temperature in the burner hearth 5 reaches the high temperature that needs sooner fuel.
Said furnace wall 4 is provided with the air blast 1 with the burner hearth internal communication, and said air blast 1 is installed in fire grate 13 belows.Air blast 1 burns for burner hearth 5 provides sufficient air, is provided with flue 19 in the burner hearth 5, strengthens the insulation effect to burner hearth 5 inside.
Said furnace wall 4 is provided with the fire door 3 that communicates with burner hearth 5 inside, and said fire door 3 is installed in fire grate 13 tops.When boiler is started working, open fire door 3, in burner hearth 5, add the bavin standing grain through fire door 3; Carry out ignition, treat stove fire burn prosperous after, open air blast 1, air-introduced machine 12; Carry out forced burning; After furnace temperature reaches requirement, watch formula spiral feed system 2 under opening, progressively get into nominal situation burning and operation.
Said furnace wall 4 is provided with explosion proof door 7, and said explosion proof door 7 is arranged on the top of fire grate 13.In combustion process owing to have a certain amount of powdered biomass to participate in burning in the fuel, the phenomenon of detonation can appear, on furnace wall 4 He in the smoke box, explosion proof door 7 has been installed all for this reason, ensure boiler continuously, move safely.
Said furnace wall 4 is provided with and the extraneous smoke box that communicates, and said smoke box is arranged on the top of fire grate 13.After the fuel completing combustion, produce a large amount of powder and drift,, handle after powder discharged burner hearth 5, ensure that boiler is permanent, safe operation through front smoke box 6 and back smoke box 8 with hot-air.
In boiler running process, air blast 1 is opened with air-introduced machine 12 simultaneously, constitutes one and quickens the circulation of air state, and gas fume after burning gets into deduster 10 dedustings through flue 9, and the flue gas after the dedusting passes through chimney 11 rows to atmosphere.Can realize the purpose of environmental protection.
Can adjust air quantity through air blast 1, air-introduced machine 12 frequency converters, watch formula spiral feed system 2 adjustment speed control inlet amounies under the interlock, the user is according to the requirements set parameter adjustment.
