Abstract
The utility model provides a combined combustion device with low-heating-value gas, and belongs to the field of combustion equipment special for industrial furnaces. The combined combustion device comprises a high-heating-value high-pressure gas spray gun, a low-heating-value low-pressure gas receiving chamber and a venturi type mixer. The combined combustion device with the low-heating-value gas is characterized in that the low-heating-value low-pressure gas receiving chamber is sleeved on the outer side of the high-pressure gas spray gun in an embedding mode, when a combustor works, low-heating-value gas is sucked into a venturi tube through negative pressure generated on the side face of the high-pressure gas spray gun, and accordingly the low-heating-value gas and high-pressure gas are mixed and enter into a furnace for combustion. According to the combustor, mixing of the high-heating-value high-pressure gas and the low-heating-value low-pressure gas is well achieved, and accordingly the problem that the low-heating-value gas is low in calorific value and is difficult to use is solved. The combined combustion device is suitable for the industrial furnace combustor field such as ceramics, glass, cement, metallurgy and chemical industries, has wide practicability, and is easy to manufacture, low in cost and easy to popularize.
Description
Technical field
The utility model relates to " a kind of mixed combustion apparatus that utilizes fuel gas with low heat value ", belongs to the technical field of industrial furnace special equipment.
Background technology
Along with improving constantly of energy-conservation cry, the utilization of fuel gas with low heat value constantly causes the concern of industry, but fuel gas with low heat value is because caloric value is low, must could improve its caloric value with the high heating value combustion gas mixing, thereby solve its use problem.
Summary of the invention
The purpose of this utility model is to provide a kind of burner that utilizes fuel gas with low heat value and high heating value combustion gas mixing, to solve the technical problem of the fuel gas with low heat value recycling of discharging in the industrial production.
The utility model provides a kind of mixed combustion apparatus that utilizes fuel gas with low heat value, and it comprises the venturi type blender, and high heating value high-pressure gas and low heat value low-pressure fuel gas are mixed, and forms the combustion gas of high pressure high heating value, thereby improves caloric value required when burning.
Mixed combustion apparatus adopts the design of nested connectivity structure, and when making high-pressure spray gun that combustion gas and air mixture are admitted to kiln, the negative pressure of its generation can drive the low heat value low-pressure fuel gas and enter the venturi type blender and mix.
This mixing burner is mainly by high heating value high-pressure gas spray gun 1, low heat value low-pressure fuel gas cavity 2, form with venturi type blender 3.Wherein the high heating value gas gun is comprised of compressed air cavity 4, high heating value combustion gas cavity 5 and high pressure nozzle 6.Its main technical characterstic is: be communicated with design by high heating value high-pressure gas and low heat value low-pressure fuel gas chamber such as figure, make burner when work, the negative pressure that forms in low heat value low-pressure fuel gas cavity one side when spraying by high-pressure spray gun gas, drive attraction low heat value low-pressure fuel gas enters Venturi tube to be mixed, and reaches the purpose of the technical problem that solves the fuel gas with low heat value recycling of discharging in the industrial production.
Description of drawings
Fig. 1 is " a kind of mixed combustion apparatus that utilizes fuel gas with low heat value " of the present utility model structural representation.
The label declaration of parts in the schematic diagram:
1 high heating value high-pressure gas spray gun, 2 low heat value low-pressure fuel gas cavitys, 3 venturi type blenders, 4 compressed air cavitys, 5 high heating value combustion gas cavitys, 6 high pressure nozzles.
The specific embodiment
" a kind of mixing burner that utilizes fuel gas with low heat value " of the present utility model mainly is comprised of with venturi type blender 3 high heating value high-pressure gas spray gun 1, low heat value low-pressure fuel gas cavity 2.Wherein high heating value high-pressure gas spray gun is comprised of compressed air cavity 4, high heating value combustion gas cavity 5 and high pressure nozzle 6.
In use, high heating value combustion gas and the compressed air of high heating value high-pressure gas spray gun are injected Venturi tube by nozzle, form high-speed jet.This moment, dynamic pressure (velocity head) reached maximum at the narrowest place of Venturi tube, and static pressure (Resting Pressure) reaches minimum of a value.The speed of gas rises because of the relation of the cross-section variation of shoving.Whole shoving all will can be experienced at one time pipeline and dwindled process, thereby pressure also reduces at one time.And then in rear side " negative pressure " district of formation (namely producing pressure differential) of venturi outlet, this pressure differential provides an external absorption affinity to fluid.This absorption affinity drives the low heat value low-pressure fuel gas and enters Venturi tube, thereby mixes, boosts with exotic fuels, reaches the effect that mixes, and the calorific value of gaseous mixture has satisfied the required calorific value requirement of kiln simultaneously.So just solved easily the purpose of the technical problem of the fuel gas with low heat value recycling of discharging in the industrial production.
Realize that preferred plan of the present utility model is: (1) has the surrounding area of the discarded combustion gas of low heat value, and existing glass, ceramic glaze, agglomerated material, other combustion apparatus or sodium silicate solid (waterglass) melting furnaces are transformed; (2) to producing the manufacturing enterprise (such as production of carbon black enterprise) of the discarded combustion gas of low heat value, advocate the production projects such as development sodium silicate solid (waterglass), glass, pottery, cement, agglomerated material, fully recycle the discarded energy, promote recycling economy development.
