Abstract
The invention relates to a secondary-combustion type energy-saving combustor. The secondary-combustion type energy-saving combustor is composed of a fuel nozzle, a gas inlet pipe, a mixing cavity, combustion heads, a combustion cavity and a secondary combustion disc. The fuel nozzle is arranged at the inlet end of the gas inlet pipe. A primary air inlet is formed in the side wall of an inlet, and the outlet end of the gas inlet pipe is communicated with the mixing cavity. The mixing cavity is of a cone-frustum-shaped cavity structure, and the multiple annularly-distributed combustion heads are arranged on the upper surface of the mixing cavity. The whole combustion cavity is of a cone-frustum-shaped structure, the lower surface of the combustion cavity is connected with the outer side wall of the mixing cavity, and a plurality of annular-distributed secondary air inlet holes are formed in the lower surface of the combustion cavity and surround the outer side of the combustion heads. An ignition hole is formed in the side wall of the combustion cavity, and the secondary combustion disc is arranged on the upper end face of the combustion cavity. Primary combustion of fuel is carried out at the combustion heads, and un-combusted fuel obtained after primary combustion passes through the secondary combustion disc at the high temperature to be secondarily combusted; the combustor is simple in structure, sufficient in combustion, even in heating and efficient, and saves energy.
Description
Technical field
The present invention relates to burner, be specifically related to a kind of secondary combustion type energy-saving burner.
Background technology
Burner is as the core component of gas kitchen ranges, and the energy-saving effect of its combustibility to whole kitchen range has material impact.At present, gas stove burner generally adopts diffusion type burning structure, and combustion air fully cannot contact and mix with fuel, and the physics incomplete combustion loss of fuel is comparatively large, and the thermal efficiency of burner is lower, and waste of fuel is serious, and energy-saving effect is poor.In addition, the combustion head distribution of normal burner is more concentrated, there is cooker heating surface center hot-spot, and the uneven phenomenon of being heated that peripheral position temperature is lower.Due to temperature distributing disproportionation, food is easily charred in overheated position, cooker center, has a strong impact on local flavor and the mouthfeel of food.
Summary of the invention
The object of the invention is the deficiency existed for above-mentioned prior art, provide one to have second-time burning function, and the energy-saving burner of homogeneous heating can be realized,
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is as follows:
A kind of secondary combustion type energy-saving burner, is made up of fuel nozzle, air inlet pipe, mixing chamber, combustion head, burning cavity, second-time burning dish; The entrance point of air inlet pipe is provided with fuel nozzle, and import sidewall is provided with an air inlet, and the port of export of air inlet pipe is communicated with mixing chamber; Mixing chamber is circular cone shape cavity body structure, and the upper surface of mixing chamber is provided with the combustion head of some annular arrangements; Described burning cavity entirety is truncated cone structure, and burning cavity lower surface is connected with the lateral wall of mixing chamber, and burning cavity lower surface is provided with the secondary intake opening of some ring-types arrangement, and secondary intake opening is centered around the outside of combustion head; The sidewall of burning cavity is provided with fire hole, and the upper surface of burning cavity is second-time burning dish.
Described second-time burning dish is structured packing structure.
The structured packing used of described second-time burning dish is preferably the corrugated structured packing of X-type or screen type structured packing.
Described second-time burning dish structured packing material used preferably uses Aludirome steel fibre or porous silicon carbide silicon materials.
Described mixing chamber, combustion head, burning cavity are preferably cast iron materials.
The import and export of described air inlet pipe are two ends flaring structure.Object is to strengthen the static pressure mixed effect that entrainment and improve the air inlet pipe port of export of air inlet pipe entrance point to an air intake.
Described combustion chamber external surface is provided with heat insulating material layer.
Secondary combustion type energy-saving burner of the present invention, fuel carries out primary combustion at combustion head place, calory burning passes through the second-time burning dish on convection current and radiation effects continuous heating flame cavity top, unburned fuel after primary combustion carries out second-time burning after the second-time burning dish higher by temperature, and achieving the burning completely of fuel, burner has the higher thermal efficiency and energy efficiency.In addition, second-time burning dish is structured packing structure, to flowing through flame and flue gas has even diffusing effect, make heating surface flame distribution evenly, realize the object to cooker homogeneous heating, the food that hot-spot can be avoided to cause such as to be charred at the problem.Burner has the advantages such as structure is simple, sufficient combustion, homogeneous heating, efficient energy-saving.
