Description

Furnace end structure of strong fire furnace Technical Field The utility model relates to the technical field of furnace heads, in particular to a furnace head structure of a strong furnace. Background In the field of gas heating equipment, a furnace end is used as a core component, and the structural design and the performance of the furnace end directly influence the combustion efficiency and the use effect of the equipment. The Chinese patent document No. CN 207094674U discloses an energy-saving five-cavity direct-injection fierce fire stove on 13 days of 2018 03 month, and the energy-saving five-cavity direct-injection fierce fire stove comprises a nozzle copper pipe, a copper sleeve, a distributor and a furnace end aluminum seat, wherein the furnace end aluminum seat is communicated with a plurality of nozzle copper pipes, the nozzle copper pipe is sleeved with the copper sleeve, the copper sleeve is provided with a convex edge, the width of the convex edge is larger than the diameter of the nozzle copper pipe below, a through hole corresponding to the nozzle copper pipe is formed above the copper sleeve, the distributor is arranged above the nozzle copper pipe, and the distributor is of a porous structure for gas to pass through. The burner comprises a burner aluminum seat, and is characterized in that a nozzle copper pipe led in from the middle of the burner aluminum seat is a central nozzle copper pipe, a distributor arranged on the central nozzle copper pipe is a central distributor, the central distributor is a structure with openings around the top seal, four nozzle copper pipes around the burner aluminum seat are outer ring nozzle copper pipes, the distributor arranged on the outer ring nozzle copper pipe is an outer ring distributor, the middle of the outer ring distributor is provided with a porous structure for fuel gas to be sprayed out, and the porous structure is wrapped with a fire collecting edge.
