Abstract
The utility model discloses a middle-heat-value coal-gas and coal-dust dual-purpose burner, belonging to the production project of the coke-oven gas by-product generated in a coke-oven plant near a fuel electric plant or an electric power station. In different operation work conditions or seasons, the superfluous by-product coal-gas production volume discharged in the air not only pollutes the atmosphere environment, but also wastes huge energy. The utility model comprises a shell (1), wherein, the shell (1) is provided with an upper multi-tube gas-fired ejector nozzle (2), an upper secondary air ejector nozzle (3), a coal dust primary air ejector nozzle (4), a lower multi-tube gas-fired ejector nozzle (5) and a lower secondary air ejector nozzle (6). An oil ignition gun (7) or a gas ignition gun is arranged at the central positions of the upper secondary air ejector nozzle (3) and the lower secondary air ejector nozzle (6). The utility model is used for a coal-dust boiler to mix combustion or change combustion of the middle-heat-value gas fuel at any time.
Description
Technical field:
The utility model relates to a kind of middle calorific value of gas coal dust dual burner
Background technology:
Near the production project that generation coke-stove gas byproducts such as coke-oven plant are arranged thermal power plant that has or the electric power station.In different operating conditions or Various Seasonal, byproduct gas yield surplus is discharged not only pollutant atmosphere to sky, also is huge energy waste.
As the middle calorific value of gas of industrial production byproduct, the fluctuation of output and caloric value is all bigger, and contains impurity such as coal tar dust, goes into stove combustion flame poor stability, and gas burner is easy to stop up, and combustion apparatus is difficult to safe and reliable operation; The flame heat transfer characteristic of adding the flame of gas combustion and coal dust firing is widely different, guarantee the boiler operatiopn steam parameter in normal range (NR), and the fuel change burner must carry out specialized designs.
Summary of the invention:
The purpose of this utility model provides a kind of burning that realizes that byproduct coal gas is reliable and stable, and the assurance pulverized-coal fired boiler is being mixed burning or changed the normal burner of back boiler operating parameter that burns gas.
Above-mentioned purpose realizes by following technical scheme:
Middle calorific value of gas coal dust dual burner, its composition comprises: housing, described housing has last multitube gas-fired spout, last overfire air port, wind snout of coal dust, following multitube gas-fired spout and following overfire air port, and the described overfire air port of going up is equipped with oil drop firelock or gas burning torch with following overfire air port centre bit.
Calorific value of gas coal dust dual burner in described, the described multitube gas-fired spout of going up is the heavy caliber jet pipe with following multitube gas-fired spout.
Calorific value of gas coal dust dual burner in described, wind snout of described coal dust is to there being the pulverized coal channel interface.
The beneficial effects of the utility model:
1. two major diameter multitube gas-fired spouts space out in the utility model, both sides about being arranged in the burner shell, wind snout of combustion air overfiren air port and coal dust is separated two major diameter multitube gas-fired spouts, multitube gas-fired spout guarantees flame stabilization with low air capacity burning, the air capacity that adjacent combustion air overfiren air port aftercombustion needs, add a combustion air overfiren air port under the following multitube gas-fired spout, each spout air distribution amount difference of while, flame location control in the burner hearth is different, can regulate the boiler operatiopn steam parameter, guarantee the operation of safe and economical boiler.Keep wind snout of coal dust in the burner, and comprise that combustion air in the multitube gas-fired spout, can be as the air distribution of coal dust firing when not having coal gas, boiler still can the combusting coal fines operation.
2. the utility model can make pulverized-coal fired boiler mix at any time and burn or change and burn calorific value of gas in the industrial byproduct, reclaims the energy, remarkable in economical benefits.
3. the utility model prevents that coal gas from discharging sky, protection atmospheric environment, obvious social benefit.

Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is side views of accompanying drawing 1.
The specific embodiment:
Embodiment 1:
Middle calorific value of gas coal dust dual burner, its composition comprises: housing 1, described housing 1 has last multitube gas-fired spout 2, last overfire air port 3, wind snout 4 of coal dust, following multitube gas-fired spout 5 and following overfire air port 6, and the described overfire air port 3 of going up is equipped with oil drop firelock 7 or gas burning torch with following overfire air port 6 centre bits.
Calorific value of gas coal dust dual burner in described, the described multitube gas-fired spout 2 of going up is the heavy caliber jet pipe with following multitube gas-fired spout 5.
Calorific value of gas coal dust dual burner in described, 4 pairs of wind snouts of described coal dust should have pulverized coal channel interface 8.
Claims (3)
1. calorific value of gas coal dust dual burner in a kind, its composition comprises: housing, it is characterized in that: described housing has last multitube gas-fired spout, last overfire air port, wind snout of coal dust, following multitube gas-fired spout and following overfire air port, and the described overfire air port of going up is equipped with oil drop firelock or gas burning torch with following overfire air port centre bit.
2. calorific value of gas coal dust dual burner in according to claim 1 is characterized in that: the described multitube gas-fired spout of going up is the heavy caliber jet pipe with following multitube gas-fired spout.
