Description
Technical field
The invention belongs to the field of combustion technology on heating furnace, glowing furnace, forge furnace, casting ladle preheating device and heat-treatment furnace.In particular to a kind of heat-accumulating burner.
Background technology
Heat-accumulating burner makes two burners with heat storage medium make furnace gas and combustion air flow in a pair and alternately, and reclaim used heat as high temperature air and realize the burner arrangement of the alternate combustion mode improving efficiency of combustion.In existing heat-accumulating burner, the burner common configuration that efficiency of combustion is higher is comparatively complicated, and volume is comparatively large, brings difficulty to the installation of equipment, later stage not easy care and bring potential safety hazard.In order to make in-furnace temperature even, flame will have higher rectilinear propagation, and this just requires that burning gases must be configured in the central axis direction of burner.Improve efficiency of combustion, can the generation of decreasing pollution thing, reduce the tail gas after burning to environment.By the improvement of structure, realize more high thermal efficiency, compact overall structure and miniaturization, safeguard summary, is the development trend of heat-accumulating burner, is also industrial current demand.The present invention relates to the heat-accumulating burner that a kind of formed by integrally casting is shaping, adopt the centre gangway of dumb-bell shape, compact conformation, efficiency of combustion is high.
Summary of the invention
The switching device shifter that heat-accumulating burner needs two burners to be one group, to switch furnace gas and combustion air, so the industrial furnace of equipment heat-accumulating burner comparatively maximizes.The sharp keen flame of rectilinear propagation excellence has the effect stirring furnace gas, being conducive to the homogenising of Temperature Distribution, on the other hand, in order to form the flame with rectilinear propagation, needing central axis direction fuel supplying part being configured in burner.In addition, to fuel supplying part heating, the liner dropping into cooling-air, heat-barrier material is needed to prevent.Thus, the maximization of structure is unavoidably caused.On the other hand, if improve the rectilinear propagation of flame, then efficiency of combustion improves and makes flame high temperature thus add the production rate of NOx.
The present invention mainly solves the problem improving heat-accumulating burner efficiency of combustion, realizes simple structure and miniaturization simultaneously.
For solving the problems of the technologies described above, the technical solution used in the present invention is: heat-accumulating burner adopts formed by integrally casting shaping, reduces between different piece and connects transitional region, simplifies installation steps, globality and compactedness better.Described heat-accumulating burner is divided into burner body and regenerator.Described burner body adopts the centre gangway of dumb-bell shape, and namely centre gangway two ends are conical section, and centre is cylindrical section.Described regenerator is divided into cylindrical and conical section, and cylindrical section connects with conical section inside described centre gangway, and configuration heat storage medium in regenerator, regenerator conical section connects the air mouth of pipe, connects air duct.Described regenerator side is provided with heat storage medium gateway, can carry out installation and the replacing of heat storage medium.Fuel channel inserts cylindrical section inner opposite end by described burner body sidepiece, and direction can be vertical with cylindrical section, also can be less than 90 ° with cylindrical section one end.Pilot burner is positioned at described cylindrical section outboard end, and direction is arbitrarily angled.Be provided with four gas passages around described centre gangway, direction is parallel with cylindrical section, and position is in described conical section.Air enters described regenerator conical section by the described air mouth of pipe to be disperseed, comparatively uniformly across heat storage medium rear portion by described centre gangway and the fuel mix to be entered by described fuel channel, after described pilot burner, there is first time burning.Another part air enters the outside conical section of described centre gangway by described gas passage, can with not clean-burning fuel generation second-time burning, improve efficiency of combustion, can flame forms be revised again, increase the rectilinear propagation of flame.When in stove during opposite side burner combustion, flue gas can collect by conical section outside described centre gangway, enters regenerator, ensure abundant accumulation of heat by 5 mouths of pipe of described centre gangway cylindrical section and described gas passage.
