Abstract

The utility model provides a gas burner for generator and belongs to the technical field of burner. The burner consists of a burner shell, a shell cover, an air inlet joint, a lance core, a swirl plate, a nozzle and a mixed tube. Combustion-supporting wind respectively forms whirl air flow and circular air flow after getting through the whirl plate, fuel gas flow fractionized by a nozzle excircle and a group of uniformly distributed small holes on an inclined cone, fuel gas sprayed out from a central hole of the nozzle and whirl air flow and circular air flow of combustion-supporting wind intersect in the range of 0 to 90-degree angle, therefore, the utility model can prevent fuel gas which is just sprayed out from fully mixing with combustion-supporting air flow and combustion, local high temperature can be generated, and combustion can be flushed in combustion interval. The utility model mainly used for ceramics furnace and other fuel gas heating equipments.

Description

The producer gas burner
Technical field
The utility model belongs to technical field of burner, especially is applicable to a kind of producer gas burner of fuel gas buring equipment such as ceramic post sintering kiln such as roller kilns, tunnel cave, shuttle kiln.
Background technology
At present, its gas spray head design of the producer gas burner of domestic use is unreasonable, gas-flow is not carried out comprehensive thin stock stream, make combustion air to the undercompounding of gas-flow, inhomogeneous, influenced burning velocity, it is low to reduce ignition temperature, the heat loss due to incomplete combustion is big, the easy coking of shower nozzle makes the harmful substance in the coal gas be difficult to decompose not environmental protection simultaneously.In addition, gas-flow is concentrated ejection, forms localized hyperthermia easily, burns out parts such as spinning disk, shower nozzle, mixing tube, makes the NOx product increase simultaneously.
Summary of the invention
The utility model provides a kind of producer gas burner, it is unreasonable to solve the gas spray head design, producing localized hyperthermia makes the NOx product increase, burn out the technical problem of burner part, gas-flow is carried out omnibearing thin stock stream, combustion air and gas-flow are mixed, fully, the order burning is evenly tiling on burner interval, improves burning quality and efficient.
The technical scheme in the invention for solving the above technical problem is: a kind of producer gas burner, it is by the burner shell, casing cover, inlet suction port, the rifle core, spinning disk, shower nozzle, mixing tube is formed, combustion air is via the burner shell, casing cover, mixing tube, the passage ejection that spinning disk is formed, be characterized in that a combustion air part is equally distributed on the spinning disk cylindrical, become the skewed slot ejection of a α angle with flame ejection central shaft, form swirling eddy, the aperture ejection of another part one group of evenly distributed axis and central axes on the spinning disk end face forms annular flow.Combustion gas from inlet suction port enter, through the passage that rifle core, spinning disk, shower nozzle are formed, a part is by one group of equally distributed aperture ejection on shower nozzle cylindrical, the oblique cone, a part is sprayed by the shower nozzle centre bore.Shower nozzle is threaded with spinning disk, gas-flow and combustion air swirling eddy, annular flow intersect in the scope at 0-90 ° of angle, so just prevent that combustion gas from just just having sprayed and combustion air current mixed combustion cmpletely, produce localized hyperthermia, burning can evenly be tiled on burner interval.One group of equally distributed aperture has segmented gas-flow on shower nozzle cylindrical, the oblique cone, makes it more full and uniform with mixing of combustion air current, and it is more stable to burn, and has reduced the heat loss due to incomplete combustion.
Compared with prior art, the utlity model has following beneficial effect: use the situation of mixing that the utility model can improve combustion air and combustion gas, avoid producing the phenomenon that localized hyperthermia increases the NOx product, the order burning is evenly tiling on burner interval, burning rapidly, the combustion space calorific intensity is big, combustion thermal efficiency height, environmental protection.
