Description
Technical field
The present invention relates to a kind of ignition system of biomass gasification fired boiler, regnition dress is added in the system
It sets, can solve the problems, such as gasification and combustion boiler at the initial stage of ignition gasification gas incomplete combustion, belong to technical field of boiler combustion.
Background technique
The deep development of biomass can promote the hair of society with using as one of the selection of future source of energy consumption rich and influential family
Exhibition.Wherein biomass combustion Land use systems are one kind the most traditional.With the development of the society, in order to improve hearth combustion temperature
Degree, the concept of gasification and combustion boiler is suggested, and obtains the attention of academia and industrial enterprise.But current gasification and combustion boiler
Gasification furnace sparking mode is used for reference, the gas incomplete combustion so that combustion chamber side there are at the initial stage of ignition fire box temperature is low, gasifies, pollution
The problem of environment.
Look back the transition of gasification furnace sparking mode.The sparking mode of common biomass gasifying furnace be by light paper or
Cloth group launches as kindling material to the bottom of gasification furnace, is subsequently filled a small amount of biomass fuel, acts on by the wind-force of air blower,
Biomass fuel is lighted, biomass gasifying furnace is finally filled up into biomass fuel and is compacted, covers, gasification furnace starts to produce gas.
This sparking mode is primarily present following problems: 1) this sparking mode does not account for the low over-emitting black exhaust of at the initial stage of ignition furnace temperature, dirty
Air is contaminated, is smoked under tears；2) mutually coordinated, easy loss of ignition is needed when starting due to needing kindling material to launch with air blower；3) it fills out
Material is performed in multiple times, cumbersome.Patent announcement CN101726002A's " a kind of ignition device for biomass gasification furnace and its makes
With method " in, a kind of fire rod being made of heating wire and ceramic tube original part is disclosed, when there is high ignition success rate, igniting
Between it is short the advantages that；A kind of biology is disclosed in " biomass gasification furnace igniting and the gasification installation " of patent announcement CN2789259Y
Matter gasification furnace igniting and gasification installation mainly solve the technical problems such as incomplete, the igniting difficulty of biomass gasifying furnace conversion；Patent
Notification number is in " ignition device of environment-friendly and energy-saving biomass gasification furnace " of CN101603693A, and stove is equipped with lighting-up tuyere, electric heating
Stick, electrical bar burn red insertion lighting-up tuyere later, and air blower blows 15 minutes extraction electrical bars and completes igniting.But above-mentioned patent is only limitted to
Biomass gasifying furnace still belongs to simple gasification furnace igniter there is no being connected with combustion chamber, does not account for igniting just
The temperature of phase combustion chamber is low, and gasification gas is difficult to form the defect of flame.
Summary of the invention
Low to solve at the initial stage of ignition fire box temperature in present biomass gasification fired boiler, gasification gas incomplete combustion is asked
Topic.The invention proposes regnition mode, one time igniter is located at biomass gasifying furnace lower end, is used for biomass fuel gas
The kindling of change；Secondary ignition device is located at the attachment device exit of gasification of biomass room and combustion chamber, is used for gasification of biomass
The kindling of gas.The setting of secondary ignition device aloows at the initial stage of ignition gasification gas to contact with ignition flame, is formed and stablize combustion
The phenomenon that ignition temperature is not achieved in burning, the temperature for avoiding combustion chamber, and gasification gas is directly discharged to chimney.
The technical solution adopted in the present invention is as follows:
The biomass gasification fired boiler with secondary ignition device includes the biomass gasification fired boiler
Including gasification of biomass room, combustion chamber, igniter, a secondary ignition device；Biomass fuel enters feeding from feed bin
Inside flood dragon, motor drives feeding flood dragon that biomass fuel is made to enter gasification of biomass room, at this time an igniter starting,
Biomass fuel burns in gasification of biomass room generates gasification gas, and gasification gas is filled by the connection of gasification of biomass room and combustion chamber
It sets and enters combustion chamber, the uncombusted biomass fuel above at the initial stage of ignition traveling-grate stoker does not have enough thickness, leads to furnace
Temperature is low, and chamber temperature does not reach requirement, and starts secondary ignition device at this time, and temperature needed for meeting gasification gas burning maintains
Flameholding.After temperature when combustion chamber reaches requirement, secondary ignition device is closed.
The application has the advantage that and good effect is: can solve existing biomass gasification fired boiler at the initial stage of ignition furnace
Temperature it is low, igniting hardly possible, over-emitting black exhaust, combustion instability the problems such as, the biomass gasification fired pot include gasification of biomass room, burn
The devices such as room, igniter, a secondary ignition device, are characterized in that: combustion system using explosive fuel (natural gas or
Oil) it lights a fire in two times to gasification and combustion boiler, wherein the fuel that an igniter is used to light in biomass gasifying furnace is used for
Gasification, secondary ignition device form stable flame for point gasification gas.
