Description
Technical field
The present invention relates to method and device that local oxygen-enriched oxygenation jet combustion supporting improves production load of combustion furnace, be applicable to various fuel and all combustion furnaces, Industrial Boiler, heating furnace, notes vapour stove, smelting furnace, ceramic kiln, glass furnace, cement kiln and incinerator etc. as fuel-firing gas-firing belong to synthetic energy-saving discharge-reducing technical field and combustion science technical field.
Background technology
The purpose of general combustion furnace all is to be used for heating, toasting certain medium or burn some material mostly, this all is necessary to reach the production load of design, but a lot of combustion furnaces particularly some old combustion furnaces because of using age long or cause combustion furnace not reach the load-bearing capacity of production needs because of business enlarges, what also have fires natural gas or gas burner because of local environmental requirement reduces sulfide emission with oil burner instead, the combustion gas after-combustion stove that changes that has does not reach the load of production requirement, and this will influence the ordinary production of combustion furnace; And if do not reach production requirement for the incinerator combustion furnace, have the poisonous and harmful substances of not burned in a large number and enter atmosphere and cause severe contamination.
General combustion furnace improves the method for producing load mainly is by reducing the heat loss transformation: comprise the insulation transformation and the flue gas heat recovery transformation of radiant section and convection section, use modern large power high efficiency burner instead and improve efficiency of combustion and improve and produce load thereby also have; But the production load proportion that these methods can improve is smaller, generally also just can only improve the production load of a few percent.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome above-mentioned deficiency and utilize relatively large Rich Oxygen Amount and local oxygen enriching burning-aid method and fluidics to improve ignition temperature, thereby the local oxygen-enriched oxygenation jet combustion supporting that improves the production load of combustion furnace improves the method for production load of combustion furnace.
Local oxygen-enriched oxygenation jet combustion supporting improves the method for production load of combustion furnace, comprises that fuel and relatively large oxygen rich gas enter to flock together in the combustion furnace separately to mix and burn, and it is characterized in that:
