Abstract

The invention relates to an ignition method for a compound burner. The invention is characterized in that the compound burner is combined by a main burner and an auxiliary burner; mixed gas flowing out from the auxiliary burner is partially-premixed burning gas; mixed gas flowing out from the main burner is fully-premixed burning gas; and heat generated by firstly burning the atmospheric partially-premixed gas flowing out from the auxiliary burner is provided for the burning of the fully-premixed burning gas of the main burner, thus a continuously flowing high-temperature environment and a fluid flame-type flame-stabilizing carrier are created for the fully-premixed burning gas of the main burner so that the rapid, full and sufficient burning reaction of the fully-premixed burning gas of the main burner can be realized without the arrangement of a real flame-stabilizing carrier or under the conditions of crash and revolution, back turning and heat storage, and the fully-premixed burning of the main burner can be realized.

Description

Be used for the ignition method on the compound burner

Technical field:

The present invention relates to a kind of ignition method that is used on the compound burner, be the fully premixed gas that the heat that produces of the atmospheric burning type gas combustion of flowing out in utilizing the auxiliary burner of this burner flows out in for main burner, create a hot environment that continues to flow and the steady flame carrier of a fluid flame-type, make the complete pre-mixing type burning of main burner no longer just can realize a kind of method of complete pre-mixing type burning with establishing steady flame carrier in kind.

Background technology:

The complete pre-mixing type burning is the known now low a kind of combustion system of efficiency height, toxic emission, the complete pre-mixing type burner of introducing in the professional book mainly contains the fire-path type flameless burner at present, ceramic wafer and wire netting infrared radiator etc., for realize stablizing, fast, complete pre-mixing type burning fully, need set up steady flame carrier or make premixed gas, rely on the self-energy condition fire burns through collision type rotation, catadioptric, accumulation of heat.Shortcomings such as burner is set up steady flame carrier the increase cost, and service life is short, and its genus flameless combustion mostly, impracticable in some field.Problems such as and the combustion system ubiquity burning of adopting combustion gas and air directly to mix is abundant inadequately, and combustion velocity is slow, and the thermal efficiency is low.Caused the significant wastage of combustion gas, toxic emission is big, contaminated environment, and energy loss is serious.

Summary of the invention:

The object of the present invention is to provide a kind of ignition method that is used on the combination burner, promptly the heat that produces with the air suspended type premixed combustion gas is that fully premixed gas is created a hot environment that continues to flow and the steady flame carrier of a fluid flame-type.The steady flame carrier or the fully premixed gas that make the complete pre-mixing type burning need not set up material object need not can realize continual and steady burning through catadioptric, collision rotation, accumulation of heat after fire hole flows out, and make heat more concentrated, help making full use of of heat.

Technical scheme:

Technical scheme of the present invention is to realize like this, the ignition method that is used on the compound burner is characterized in that: this burner is combined by main burner and auxiliary burner, what auxiliary burner flowed out is the gas that combustion gas and the required part air of burning are pre-mixed, and what main burner flowed out is the gas that combustion gas and the required whole air of burning are pre-mixed; The mist that auxiliary burner the flows out heat that produces of the burning fully premixed gas for flowing out in the main burner that continues not continue is in advance created a hot environment that continues to flow and the steady flame carrier of a fluid flame-type, and the gas of major-minor burner outflow is burnt simultaneously.The auxiliary burner effluent air can independently burn, and the main burner effluent air can not independently be finished burning.

Beneficial effect:

The good effect of patent of the present invention is that this burner has major-minor two cover combustion systems, has promptly optimized burning situation and has improved combustibility again greatly.The complex combustion mode has realized high efficiency complete pre-mixing type burning, realizes big intensity and high efficiency that heat transmits by convection current simultaneously.

The burner structure innovation is ignited fully premixed gas combustion in partly-premixed gas combustion mode.Be widely used in civilian, commercialization and industrial circle.
