Description
[technical field]
The utility model relates to a kind of particle fuel combustion device.
[background technology]
Biomass granule fuel is a kind of form of biomass solid fuel, being a kind of green, environmental protection (greenhouse gases zero-emission), regenerative resource, is that national policy encourage to be promoted and will replaced the new forms of energy product of traditional energy (coal, oil) from now in a large number.The outstanding combustion characteristics of biomass granule fuel is exactly its graininess, and contains very high fugitive constituent (generally about 70%).When biomass granule fuel burnt, fugitive constituent was heated and overflows rapidly, was difficult to complete after-flame under the condition of flammable composition wherein (CmHn, CO etc.) and anoxic not high enough at combustion reaction temperature, and cracking produces polluters such as a large amount of carbon blacks, tar on the contrary.Produce thick smoke on the one hand, cause flue gas loss increase and air environmental pollution; These pollutants also can cause smoke evacuation not smooth attached on outlet flue and the heat-transfer surface on the other hand, and heat exchange efficiency reduces, and need often to remove these attachments.
The combustion technology of biomass granule fuel generally is divided at present: forward combustion (grate firing) mode, gasification, and combustion mode and reverse burning mode.
Forward combustion takes flame to burn above fuel, the mode that fuel adds above flame again.Be characterized in: meet the cognition of people to the burning form, burning structure is simple, and is easy to use; But during the biological substance for combustion granular fuel, be difficult to fully burning, thereby pollute.
Gasification, and combustion is taked fuel to carry out earlier imperfect combustion under anaerobic environment and is produced fuel gas, fuel gas is drawn the mode of burning again.This combustion system easily produces liquid pollutant, so national environmental protection department represents that clearly under the condition that pollutant can't be handled, this combustion technology should not be promoted.
Reverse burning takes flame to burn in front, and the mode that fuel adds later at flame relatively is fit to the biological substance for combustion granular fuel, and sufficient combustion, and pollutant emission level is low.The reverse burning mode roughly can be divided into again at present: 1) double combustion chamber's version: cup is the solid phase combustion chamber, and back chamber is the gas-phase combustion chamber.Fuel is subjected to thermal cracking to produce fuel gas at cup, and fuel gas enters the chamber, back and burns.This structure is generally taked to increase chimney or installs air-introduced machine additional to carry out negative-pressure firing, because the graininess of biomass granule fuel causes performance of ventilating relatively poor, so this structure is not suitable for the biological substance for combustion granular fuel; The great weakness of this structure is: have easy scaling loss position.2) watch material version under the spiral pushing tow: this structure generally adopts forced-air blast to carry out pressure combustion, can regulate feeding coal and air quantity is controlled burning velocity, easily realizes control automatically, is fit to the biological substance for combustion granular fuel; Shortcoming is: granular fuel is very easily pulverized in break-in pushing tow extrusion process, and should not maximize.
Because a large amount of uses of biomass granule fuel, all there is different weakness again in above-mentioned combustion technology, therefore, is necessary to provide a kind of simple in structure, easy to use, and applicability is extensive, and discharging is low pollutes, and enables the novel burner of completing combustion.
