Description
Technical Field
The utility model relates to a combustor with stainless steel furnace end.
Background
The combustor comprises a furnace end and a distributor arranged on the furnace end, wherein the furnace end is generally integrally cast by cast iron.
The problem is that the cast iron furnace end has the defects of heavy weight, high cost and easy corrosion of the interior, the production cost of the burner is increased, the long-term use of the burner is not facilitated, and certain limitation exists.
Therefore, further improvements are needed.
In addition, in the prior art, the burner includes a gas distribution plate, an outer ring fire cover arranged on the gas distribution plate, and an inner ring fire cover arranged on the gas distribution plate and located inside the outer ring fire cover.
