Abstract
A novel boiler for the combustion of a biomass pressing block comprises a boiler body and a hearth located in the boiler body, wherein a feeding opening and a slag discharging opening are formed in the boiler body; a dust collector communicated with the hearth and an induced draft fan communicated with the dust collector are further arranged in the boiler body; a flue is connected with the dust collector and the induced draft fan and then extends to the outside from the upper end of the boiler body; a water-bearing layer formed by a water pipe is further arranged in the boiler body; and one end of the water pipe is a water inlet formed in the boiler body, while the other end is a water outlet formed in the boiler body. The novel boiler improves the thermal efficiency only by changing the connection relationship between the components without increasing the cost, thereby achieving good energy conservation and emission reduction effects.
Description
Technical field
The utility model relates to fluid heater technical field, especially relate to a kind ofly make full use of fume afterheat, reach energy-efficient object, for biomass block burning boiler.
Background technology
In prior art, boiler is made up of boiler body and auxiliary equipment, and burning matter completes burning in boiler body, and the high-temperature flue gas producing after burning is discharged by the function auxiliary equipment of blower fan, deduster.This kind of a large amount of heat energy of boiler is discharged with flue gas, high fume temperature, and combustion thermal efficiency is low.
In order to improve heat utilization rate, publication number is that the utility application of CN101408308 discloses a kind of coal-burning boiler, this boiler comprises body of heater and the high-temperature surface being connected and low temperature heating surface, lower portion of furnace body is provided with fire grate, fire grate top is provided with burner hearth, fire grate bottom is provided with lower air blast, this lower air blast communicates with combustion chamber of furnace body, the flue gas of burner hearth enters the first deduster by high-temperature surface and low temperature heating surface, deduster downside is connected with the first flue gas recirculation pipeline, this the first flue gas recirculation install pipeline has recirculation blower, and be connected with lower air blast by appendix, flue gas and furnace bottom combustion air are mixed into furnace bottom combustion chamber.Downside due to deduster in this boiler connects flue gas recirculation pipeline, and flue gas is mixed into furnace bottom combustion chamber by recirculation blower and furnace bottom combustion air, thereby reduces the amount of carrying soot particle in flue gas, improves boiler combustion efficiency.In conjunction with its bright book accompanying drawing, deduster is independent of body of heater outside, in burner hearth, flue gas enters deduster after by high-temperature surface and low temperature heating surface, deduster is arranged the dust in flue by chimney is outer time, in deduster, remaining smoke heat energy again carries out heat energy utilization after gas transmission road enters burner hearth at lower air blast.Although this boiler is compared to conventional art, improve heat utilization rate, but high-temperature flue gas is transported to the process that deduster turns back to burner hearth again and still had hot loss of energy from burner hearth, and the heat energy containing in the dust put outward of deduster has also caused the direct losses of heat.
Summary of the invention
The purpose of this utility model is do not changing under existing boiler part prerequisite, further reduce the flue-gas temperature of discharging, thereby improve the biomass block burning boiler of heat utilization rate, the technical scheme adopting is: a kind of novel biomass briquetting burning boiler, comprise body of heater and the burner hearth that is arranged in body of heater, body of heater is provided with dog-house and removes cinder notch, it is characterized in that: in described body of heater, be also provided with the deduster being communicated with burner hearth and the air-introduced machine being communicated with deduster, flue extends body of heater from body of heater upper end after connecting deduster and air-introduced machine; In described body of heater, be also provided with the water-bearing layer that water pipe forms, described water pipe one end is the water inlet being located on body of heater, and the other end is the delivery port being located on body of heater.
Technical characterictic of the present utility model also has: described water-bearing layer is between burner hearth and deduster.
Technical characterictic of the present utility model also has: described water-bearing layer is also between deduster and the body of heater of burner hearth opposite side.
Technical characterictic of the present utility model also has: the lower end of described deduster connects the dedusting mouth on body of heater.
Technical characterictic of the present utility model also has: described dedusting mouth is 2.
Technical characterictic of the present utility model also has: on described body of heater, just burner hearth place is provided with to observation panel.
Technical characterictic of the present utility model also has: on described air-introduced machine, be also provided with blower motor.
Technical characterictic of the present utility model also has: on described body of heater, be also provided with limnimeter.
The beneficial effects of the utility model are: this boiler has changed the position relationship between body of heater, deduster and air-introduced machine in conventional boiler, flue is drawn high-temperature flue gas and is entered into deduster dedusting and discharge outside body of heater through flue from burner hearth, high-temperature flue gas its heat energy in flue course of conveying is directly absorbed by water-bearing layer, thereby make this boiler in heating exhaust steam, also can draw hot water; Heat energy make full use of the flue dust temperature that has reduced outer discharge boiler, outer smoke evacuation dirt is lowered into 90-100 degree Celsius of left and right above from 300 degrees Celsius, thereby greatly reduces hot loss of energy, reached the object of energy-saving and emission-reduction.The utility model, not increasing under the prerequisite of cost, has only changed the annexation between parts, has improved the thermal efficiency, has the effect of good energy-saving and emission-reduction.
