Description
Technical field
The utility model relates to the Regenerative Combustion Technology field, particularly relates to a kind of single regenerative burner that is used on industry heating furnaces such as metallurgy, machinery, non-ferrous metal and the heat-treatment furnace.
Background technology
Heat-accumulating burner is used early abroad, and states such as early 1980s Great Britain and America have developed two energy storage bed burner system.Japan is very fast also to develop this heat-accumulating burner technology, and widelys popularize.Though the progress of China is used later with synchronously external.From in July, 1997 this technology application success so far, the application of regenerative combustion technology in the heating furnace field progressively improves and is ripe.
Can be divided into two kinds of air single regenerative burner and the two heat-accumulating burners of air gas from the heat storage medium classification of heat-accumulating burner.From the material that heat storage uses, use Ceramic Balls, ceramic honeycomb body, rubble etc., particularly ceramic honeycomb body heat-accumulating burner to pay attention to abroad with small and exquisite the obtaining of its structure.Domestic heat storage then mainly uses two kinds of Ceramic Balls and ceramic honeycomb bodies.
Present domestic single regenerative burner mainly contains following several different structure form:
1. the concentric direct insertion single regenerative burner of jet
This structure burner external form is a cylindrical shape, and combustion gas is from the combustion gas spout ejection at burner center, and air port is positioned on the concentric circles of combustion gas spout; Honeycomb ceramics is arranged at around the blast tube with the circumference form, honeycomb shaped is a circular arc, and burner block and burner shell are integral structure, are installed on the furnace side, its characteristics are that combustion gas is adopted concentric mode of jet with air, the burning good mixing effect, but its honeycomb ceramics is an arc-shaped structure, the installing/dismounting inconvenience, burner block and housing are integral structure, burner block intensity and life-span all effected, and field-strip replacing separately takes place when damaged in an independent place.
2. the single regenerative burner of combustion gas below ejection
This structure burner is split type, air port and combustion gas spout are arrangement form up and down, combustion gas is from the ejection of air below, help making the furnace gas of workpiece to be reducing atmosphere, but since the air burner take up space bigger, the arranged beneath gas gun, two bursts of air-flow centre-to-centre spacing are bigger, the burning premixing effect is relatively poor, and its arrangement form limits to some extent to the furnace height of heating furnace in addition, requires to have enough height placement burners.
3. the coal gas air single regenerative burner that do not commutate
The type burner has gas supply all the time in gas gun, do not commutate in the use.Be provided with two regenerator in the burner, flue gas and air alternately pass through two regenerator by four-way change-over valve.Burner can singlely be provided with use.But it is bigger that this structure burner takes up room, and complexity is installed, and have refractory material to separate in the middle of two regenerator, occurs damaged situations such as crackle in the use that constantly commutates easily, makes the flue gas heat accumulating type intercommunication of having leisure, and the repair and maintenance amount is big, and repairs difficult.
The huge space that above-mentioned in addition single regenerative burner accumulation of heat chamber on the furnace wall is occupied with the bulk strength that increases furnace wall, improve heat storage capacity, can place single regenerative burner outside the furnace wall usually, and it is more flexible that burner is arranged.When but the existing external furnace wall of single regenerative burner was outer, its accumulation of heat chamber and furnace wall were vertical stratification, exist the huge problem in space, furnace side that takies
