Abstract
The utility model relates to a biomass two-phase fuel boiler burning the biomass fuel, which aims to overcome such problems as instable burning, black smoke, low heat efficiency and frequent slag bonding at the heat exchanging surface of the prior biomass boiler. The boiler is mainly formed by a boiler cylinder heat exchanging device and a burning device. The boiler cylinder heat exchanging device is positioned above the burning device. A boiler cylinder(18) is internally provided with a smoke pipe(2) as the convection heat exchanging surface; one end of the smoke pipe(2) is communicated with the hearth through a smoke case(1), and the other end of the smoke pipe(2) is communicated with a smoke outlet(5). Moreover, the burning device consists of a gas phase combustion chamber(16) and a fixed phase combustion chamber(9), wherein, the upper part of the gas phase combustion chamber(16) is provided with a fuel inlet(17), and the lower part of the gas phase combustion chamber is communicated with the hearth; the bottom of the fixed phase combustion chamber(9) is provided with a fixed fire grate(11) and a movable fire grate(12) which is arranged at the lower part of the gas phase combustion chamber(16).
Description
Technical field
The utility model relates to a kind of boiler of burning-used biologic mass fuel.
Background technology:
In recent years, more and more be subject to people's attention,, extensively adopted the grain forming fuel technology in order effectively to utilize these biomass energies such as biomass fuels such as maize straw, rice husks.Biomass granule fuel is a kind of reproducible green energy resource.Apply energy policy and environmental protection policy that this kind fuel meets China.But there is combustion instability in the biomass boiler of Chu Xianing in the market, over-emitting black exhaust, and the thermal efficiency is low, and therefore problems such as the easy slagging scorification of heat-transfer surface, are necessary to develop the novel biomass shaped fuel boiler that overcomes the problems referred to above, solve the demand in market.
Summary of the invention:
The purpose of this utility model is to overcome in the market the biomass boiler that occurs and has combustion instability, over-emitting black exhaust, and the thermal efficiency is low, and problems such as the easy slagging scorification of heat-transfer surface provide a kind of high-efficiency low-pollution living beings two-phase fuel boiler of biological substance for combustion granular fuel.
Above-mentioned purpose of the present utility model is achieved in that accompanying drawings is as follows:
Living beings two-phase fuel boiler mainly is made up of drum heat-exchanger rig and burner, the drum heat-exchanger rig is positioned at the top of burner, the drum of drum heat-exchanger rig (18) inside is provided with the smoke pipe (2) as the heat convection face, one end of smoke pipe (2) is communicated with burner hearth by smoke box (1), the other end is communicated with outlet flue (5), said burner is made up of gas-phase combustion chamber (16) and solid phase combustion chamber (9), the top of gas-phase combustion chamber (16) is fuel input port (17), the bottom is communicated with burner hearth, bottom, solid phase combustion chamber (9) is fixed grate (11) and moving grate (12), and moving grate (12) is located at the bottom of gas-phase combustion chamber (16).
Said moving grate (12) drives moving grate (12) by hydraulic pressure pusher (14) by hydraulic cylinder (7) and moves back and forth.
Said burner hearth rear portion is provided with rear arch (8), and its Hou Kou place is provided with and overfiren air port (4).
The utlity model has following technique effect: in the primary zone of boiler is gas-phase combustion, belongs to clean combustion, is the solid phase burning on boiler grate, with the uncompleted burned carbon burning fully, has realized efficient burning.This furnace type structure novelty, energy-efficient, discharging is clean, has application market widely.

The specific embodiment
Further specify the particular content of the present utility model and the course of work thereof below in conjunction with the accompanying drawing illustrated embodiment.
The utility model is mainly by gas-phase combustion chamber (16), and solid phase combustion chamber (9), hydraulic pressure pusher (14), moving grate (12), fixed grate (11), rear arch (8), overfiren air port (4), drum parts such as (18) are formed.
Consult shown in Figure 1: this type of furnace is a horizontal type structure, and the bottom is divided into burner, and top is divided into the drum heat-exchanger rig.Upper lateral part at boiler is provided with dog-house (17), and biomass grain forming fuel enters gas-phase combustion chamber (16) thus.In gas-phase combustion chamber (16), fuel is through super-dry, pyrolysis, gasification, and combustion then, and the high-temperature flue gas after the burning enters burner hearth by gas-phase combustion chamber (16) bottom.Bottom, gas-phase combustion chamber (16) is provided with moving grate (12), and this fire grate drives hydraulic cylinder (13) by hydraulic pressure pusher (14) and moves reciprocatingly, and the fuel of bottom, gas-phase combustion chamber (16) is moved to fixed grate (11).The biomass fuel that does not burn on fixed grate (11) continues to do solid phase burning, the ash that the burns ash entrance chamber (7) that falls.High-temperature flue gas in burner hearth with water-cooling wall (10) radiant heat exchange after, enter drum (18) rear portion smoke pipe (2) by the rear arch aditus laryngis.At the aditus laryngis place of rear arch (8) secondary air channel (4) is set, secondary wind forms air curtain with ejection from then at a high speed, thereby promotes unburnt carbon granules after-flame in the flue gas.High-temperature flue gas in smoke pipe (2) with drum (18) in working medium carry out heat exchange after, from outlet flue (5) by air-introduced machine suction chimney.As shown in Figure 1, backwater and moisturizing enter boiler by water inlet (6), and hot water that working media outlet (3) is come out or steam are supplied with user's use.
An application example of the present utility model is: leaving water temperature is 95 ℃, and return water temperature is 70 ℃, and power is 350KW, and the thermal efficiency is up to more than 80%.
