The lower part of the combustion chamber is provided with a fire grate, a feeding device and an ignition device, wherein the feeding device is used for feeding the biomass particle fuel to the fire grate, and the ignition device is used for igniting the biomass particle fuel on the fire grate; the upper part of the combustion chamber is communicated with a smoke channel, the shell pass of a heat exchanger is communicated with the water in the water jacket, and the tube pass of the heat exchanger is connected in the smoke channel in series; the tail end of the smoke channel is communicated with the inlet of a cyclone dust collector; and the outlet of the cyclone dust collector is provided with a draught fan.
Description
Technical field
The utility model relates to a kind of hot-water boiler, specifically, is a kind of normal-pressure hot-water boiler that acts as a fuel with biological particles.
Background technology
Existing biomass granule fuel normal-pressure hot-water boiler is higher to demanded fuel, requirement is that combustion process can coking, and calorific value is more than 4000 kilocalories, otherwise it is flame-out to cause boiler a period of time to occur, or it is not enough to exert oneself.The dust of biomass granule fuel boiler emission is bigger now simultaneously, also impacts to environment.This has relatively high expectations with regard to the selection of giving the biological particles raw material, and general the requirement is the wood chip of factory floor, makes because the restriction of fuel is provided with bottleneck for the popularization of biological particles boiler.
Summary of the invention
When providing a kind of burning, the purpose of this utility model can not stop working the hot-water boiler that the dust of discharging is few.
The hot-water boiler of this use biomass granule fuel, comprise housing, be arranged on water jacket and combustion chamber in the housing, the bottom of combustion chamber has fire grate, carry the pay-off of biomass granule fuel on fire grate, to the igniter of the igniting of the biomass granule fuel on the fire grate, top, combustion chamber communicates with flue, water in the shell side of heat exchanger and the water jacket is logical, and the tube side of heat exchanger is connected in the flue; End at flue is connected with the inlet of cyclone dust collectors; The outlet of cyclone dust collectors is provided with air-introduced machine.
The beneficial effects of the utility model: because cyclone dust collectors are set, after dust in the flue enters cyclone dust collectors, bigger dust can be deposited to the bottom of cyclone dust collectors gradually, less dust just can be discharged through the outlet of cyclone dust collectors with flue gas, formed filtration to flue gas, therefore, the dust of discharging is few.Because air-introduced machine arranged, during air-introduced machine work, flue is aspirated again, make a large amount of air enter the combustion chamber, sufficient combustion can not stop working, and the raw material of biological particles is not had specific (special) requirements, wide adaptability.
Above-mentioned hot-water boiler, described fire grate are many parallel transfer rollers, and its transmission mechanism that rotates to a direction of each transfer roller and drive links to each other.Side at fire grate has slag removing chamber; The waste residue that biomass granule fuel burning back forms enters slag removing chamber when transfer roller rotates.Adopt transmission mechanism (as the chain-type transmission mechanism) to drive fire grate, make and to discharge automatically after the fuel coking, the combustion space is provided for new fuel, enter slag removing chamber by long after making fuel to be fully burned apart from fire grate, the waste heat of slag removing chamber can also heat the cold water that covers, adopt cyclone dust collector again after the many backhauls of flue gas simultaneously, cyclone dust collectors also allow the waste heat of flue gas be absorbed by water once more in dust removal process.Make that like this boiler combustion efficiency is higher, discharging is cleaning more, can use simultaneously low heating value such as stalk particle to get fuel, stalk is utilized again play positive role.
Above-mentioned hot-water boiler has cleaning door on the flue, the cleaning door place is provided with adjustable damper.The cleaning door fire door is provided with damper, can mend wind by secondary, so that allow the more abundant burning of fuel.
Above-mentioned hot-water boiler, pay-off are spiral pay-off.

The specific embodiment
Normal-pressure hot-water boiler referring to the coking biomass granule fuel shown in Fig. 1-4 (low heating value biomass granule fuel) comprises housing 1, is arranged on water jacket 2 and combustion chamber 3 in the housing, and the bottom of combustion chamber has fire grate 4.
Fire grate 4 is many parallel transfer rollers, and its chain-type transmission mechanism 5 that comprises fire grate driving motor 51, chain 52 that rotates to a direction (counterclockwise or clockwise) of each transfer roller and drive links to each other.
Carry the spiral pay-off (auger) 6 of biomass granule fuel on fire grate, be included in the screw rod, the screw tube that rotate under the charging driven by motor, the charging aperture of screw tube communicates with the bottom of fuel tank (feed bin) 13, and the discharging opening of screw tube is in fire grate one side.The fire grate opposite side relative with the discharging opening of screw tube has slag removing chamber 7.The waste residue that biomass granule fuel burning back on the fire grate forms enters slag removing chamber 7 when transfer roller rotates.
Fire grate one side at the discharging opening place of screw tube also is provided with at the electrothermal igniter (igniter) 12 to the igniting of the biomass granule fuel on the fire grate.3 tops, combustion chamber communicate with flue 8.End at flue is connected with the inlet of cyclone dust collectors 9; The outlet of cyclone dust collectors is provided with air-introduced machine 10.Water in the shell side of heat exchanger 11 and the water jacket is logical, and the tube side of heat exchanger is connected in the flue.Have a plurality of cleaning doors on the flue, each cleaning door place is provided with adjustable damper.
This boiler adopts microcomputerized control, automatic feed, and air inducing automatically is provided with the leaving water temperature of prescribed limit, water outlet automatically, excessive low water level protection, overtemperature prote, one-touch open mode arbitrarily.Opening power; start automatic button; boiler at first starts air-introduced machine and got rid of the fuel gas that may exist in 2 minutes; charging machine operation then is transported to the fuel of feed bin on the fire grate by auger; the electrothermal igniter is opened on the fuel of piling up and is sprayed high temperature hot gas and flame; about one minute particle is lighted; igniting is closed; drive fire grate is started working; the particle slag (waste residue) of after-flame is entered slag removing chamber; the particle flame of burning and flue gas along with the suction of air-introduced machine in heat exchanger tube and water jacket; the cleaning door fire door is provided with damper, can mend wind by secondary, so that allow the more abundant burning of fuel; flue gas enters cyclone dust collector, discharges through the HTHP air-introduced machine at last.When closing boiler, the blowing out key that touches the button, feed system quits work, and fire grate works on, and treats to stop simultaneously when air-introduced machine stopped after 10 minutes, and fire grate no longer includes fuel, prevents because burner hearth has the fuel workman to cause that After Hours Bunker is on fire.
Adopt the chain transmission type fire grate, make and to discharge automatically after the fuel coking, give new fuel combustion space, enter slag removing chamber by long after making fuel to be fully burned apart from fire grate, the waste heat of slag removing chamber can also heat the cold water that covers, adopt cyclone dust collector again after the many backhauls of flue gas simultaneously, cyclone dust collectors also allow the waste heat of flue gas be absorbed by water once more in dust removal process.Make that like this boiler combustion efficiency is higher, discharging is cleaning more, can use simultaneously low heating value such as stalk particle to get fuel, stalk is utilized again play positive role.
The utility model, more reasonable structure, the thermal efficiency is higher.
