Abstract

The utility model discloses a biomass boiler, include the shell barrel and be located the stove base of shell barrel below, be provided with stove courage barrel in the shell barrel and be located the room barrel that strile -backs of stove courage barrel top, stove courage barrel with the room barrel that strile -backs is inside to communicate with each other, the room barrel that strile -backs is provided with first tobacco pipe group and communicates in the lower smoke box that is located the below, lower smoke box passes through second tobacco pipe group and communicates in last smoke box, it is provided with the exhaust port to go up the smoke box. Adopt above -mentioned technical scheme, living beings pellet fuel is at the stove courage barrel and the suspension firing that beats in the barrel of room that strile -backs to can follow to the reasonable overgrate air of supply in furnace transport biomass fuel's the screw feeding pipe, increase the flue gas disturbance, make its burning completely, the vertical heater courage and the room constitution furnace structure of strile -bacing in time siphon away the radiant heat, the vertical tobacco pipe in group of arranging becomes the flue gas convection current, and heat exchange is more abundant, and is more thorough.

Description

A kind of biomass boiler
Technical field
This utility model relates to field of boilers, a kind of novel biomass granule boiler.
Background technology
Steam generator (being commonly called as boiler) is that the heat energy utilizing fuel or other energy is heated as the plant equipment of hot water or steam water, is the important component part of Steam Power Equipment.Station boiler, steam turbine and electromotor are the main frames of heat power station, and therefore station boiler is the visual plant producing electric energy.Biomass boiler is a kind of biomass boiler, be exactly with biomass energy as the boiler of fuel biomass boiler, be divided into biomass steam boiler, biomass hot water boiler, biomass thermal wind furnace, biomass heat-conduction oil oven, vertical type biomass boiler, horizontal biomass boiler etc..Biomass boiler generally includes feeding system, combustion system, soot blower system, air and gas system and control system, and feeding system is generally made up of parts such as feed bin, vibra feeder, screw(-type) feeder, screw feeder pipes;Combustion system is made up of parts such as burner, blower fan, lighters;Burner hearth and smoke pipe can be purged by soot blower system in timing, it is ensured that smoke pipe surface occurs without dust stratification, supply air system and burner integrated arrangement, and air delivers to burner hearth through aerator by burner, reach to carry fuel and combustion-supporting effect.Biomass boiler of the prior art, also exists biomass granule fuel in the insufficient defect of stove chamber inner combustion, and after burning, radiant heat can not be siphoned away in time, and when smoke pipe is discharged fume, heat exchange is insufficient, and the ash in flue gas can be at smoke pipe building up inside.
Utility model content
Therefore, the technical problems to be solved in the utility model is to provide a kind of sufficient biomass boiler of heat exchange, by the mechanism of appropriate design smoke pipe enable heat that biomass fuel combustion produces in smoke pipe in time, swap up hill and dale, improve the thermal efficiency filtered.
To achieve these goals, a kind of biomass boiler of the present utility model, including shell cylinder and be positioned at the furnace base below described shell cylinder, being provided with flue cylinder in described shell cylinder and be positioned at the return combustion chamber cylinder above described flue cylinder, described flue cylinder communicates with described return combustion chamber inner barrel;Described return combustion chamber cylinder is provided with the first smoke pipe group and is communicated in the lower smoke box being positioned at lower section;Described lower smoke box is communicated with upper smoke box by the second smoke pipe group, and described upper smoke box is provided with exhaust opening.
Described first and second smoke pipe group includes many smoke pipes respectively.
The respective many smoke pipes of described first and second smoke pipe group be arranged in parallel.
Described smoke pipe is threaded flue.
Described second smoke pipe group is vertically arranged.
Described return combustion chamber cylinder includes the most outwardly in the protuberance of described flue cylinder, and described first smoke pipe group is connected to the lower end of described protuberance, and described first smoke pipe group is vertically arranged.
Use technique scheme, biomass boiler of the present utility model, relative to prior art, have the advantages that
1, biomass granule fuel is beated suspension combustion in flue cylinder and return combustion chamber cylinder, it is possible to feeds rational secondary wind from the spiral feed pipe to burner hearth conveying biomass fuel, increases flue gas disturbance, promotes its burning completely;
2, vertical flue and return combustion chamber composition chamber structure, siphon away radiant heat in time;
3, the smoke pipe group vertically arranged forms smoke convection, and smoke pipe is threaded flue, and heat exchange is more abundant, more thoroughly;
4, being to move towards up and down due to flue gas, in boiler operatiopn, heating surface pipe is not easy dust stratification.
5, thermal effect is high, and biomass granule fuel burning fully, reaches energy-conservation purpose.

Detailed description of the invention
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
The present embodiment provides a kind of biomass boiler, including shell cylinder 7 and be positioned at the furnace base 9 below described shell cylinder 7, being provided with flue cylinder 6 in described shell cylinder 7 and be positioned at the return combustion chamber cylinder 4 above described flue cylinder 6, described flue cylinder 6 is internal with described return combustion chamber cylinder 4 to be communicated;Described return combustion chamber cylinder 4 is provided with the first smoke pipe group 18 and is communicated in the lower smoke box 21 being positioned at lower section, is communicated with the second smoke pipe group 19 between upper smoke box 17 and lower smoke box 21;Described upper smoke box 17 is provided with exhaust opening 22.
Using said structure, biomass granule fuel is beated suspension combustion in flue cylinder and return combustion chamber cylinder, it is possible to feeds rational secondary wind from the spiral feed pipe to burner hearth conveying biomass fuel, increases flue gas disturbance, promotes its burning completely.
Vertical flue and return combustion chamber composition chamber structure, siphon away radiant heat in time.
In order to reach the purpose of heat exchange uniform high-efficiency, described first and second smoke pipe group includes many smoke pipes respectively, and the respective many smoke pipes of described first and second smoke pipe group be arranged in parallel;The most described smoke pipe is threaded flue.Smoke pipe group forms smoke convection, and as the arrow in Fig. 2 is oriented to the trend of flue gas, and smoke pipe is threaded flue, and heat exchange is more abundant, more thoroughly;
Described second smoke pipe 19 groups is vertically arranged.
Described return combustion chamber cylinder 4 includes the most outwardly in the protuberance 4a of described flue cylinder, and described first smoke pipe group 18 is connected to the lower end of described protuberance 4a, and described first smoke pipe group 18 is vertically arranged.
Owing to flue gas is to move towards up and down, in boiler operatiopn, heating surface pipe is not easy dust stratification.
Biomass boiler of the present utility model, thermal effect is high, and biomass granule fuel burning fully, reaches energy-conservation purpose.
Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And among the protection domain that the obvious change thus extended out or variation are created still in this utility model.
