Description
Technical field
The invention belongs to coal gasification apparatus igniting field, the plasma ignition side of the gasification furnace of fine coal charging is referred in particular to
Formula, is the improvement to existing powder coal gasification furnace sparking mode.
Background technology
Plasma igniter is a kind of new igniter in recent years, and its principle is to utilize arc excitation high-temperature plasma
Body, pilot fuel.Plasma Firing Technology is just being widely used in aircraft industry, shipbuilding work as a kind of new firing technique
In all conglomeraties such as industry and generating, oil and gas transmission.And plasma igniter is new as one kind of modern gas turbines
Type ignition installation, with unique flash-over characteristic and larger discharge energy, energy is concentrated, and the igniting of engine can be made reliable
Property and igniting concentration limit.When injecting fuel with high temperature air plasma jet in plasma igniter, issued in fuel-rich state
Complicated and violent a series of physical chemical reaction simultaneously occurs for raw heat transfer, mass transfer, its Pintsch process with gas and fuel and
Restructuring, includes the pilot process of complexity, and the speed respectively reacted is not quite similar, therefore course of reaction is considerably complicated.
In Application No. CN201210169749.X patent document, a kind of repeatable plasma utilized of negative electrode is disclosed
Igniter, can extend the service life of negative electrode, save material, reduce the manufacturing cost of plasma igniter.
In Application No. CN201210169748.5 patent document, a kind of plasma ignition spray differential windward is disclosed
Mouth, can reduce the eccentric effect of plasma-arc, so as to ensure effective active length of electric arc, enable electric arc fully with combustion
Material-air mixture contact, it is ensured that igniting reliability.
In Application No. CN201510883864.7 patent document, a kind of plasma igniter, antipollution energy are disclosed
Power is strong, and anode service life is long, adapts to air ratio scope wide.
But, due to presence and plasma-arc the characteristic in itself for the gas that combustion chamber high speed flows, cause
Ion stream is not enough concentrated, and the effective length of plasma-arc is shorter, causes ignition success rate to reduce.
And all there is certain drawback because of its working method in other conventional ignition burners：
High energy spark discharge igniter time delay is longer, and ignition energy is not enough concentrated, and igniting reliability is not high；Deng from
The nozzle of sub igniter indirectly is also easy to produce carbon distribution problem；Space needed for station boiler plasma igniter is big, and power
It is required that higher.
It can be control effectively it is an object of the invention to provide a kind of with the direction of article on plasma electric arc, make plasma jet
More concentrate, increase its effectively igniting diameter, a kind of magnetic field-intensification for improving ignition success rate is oriented to plasma ignition nozzle.
The content of the invention
