Abstract
A burner which is capable of burning a very lean mixture of flammable vapors and air, and which preferably also can burn a mixture of varying richness and B.T.U. content, with the burner desirably including a structure forming an upwardly facing recess and an inlet for introducing the vapor-air mixture into a lower portion of that recess in a relation enabling the mixture, when lean, to burn at least partially in the recess in isolation from external air, and when richer to burn at an upper elevation at which external air can mix with the basic vapor-air mixture.
Claims12
Vapor burning apparatus comprising:
- a structure forming a recess which opens upwardly and which has an upwardly projecting peripheral side wall extending about the recess;
- inlet means for introducing into said recess at a lower level therein a mixture of flammable vapor and air which have been premixed before reaching said inlet means;
- said recess being closed against admission of additional air thereinto at the bottom of the recess and upwardly along said side wall to an upper level which is spaced above said level of introduction of the mixture into the recess, at which upper level external air can communicate with the recess;
- and means for producing said vapor-air mixture and delivering it to said inlet means, and acting to vary the vapor-air ratio thereof between a relatively lean mixture which can support combustion without additional air and burns at least partially within said recess before rising to said upper level and while isolated from external air by said structure, and a relatively rich vapor air mixture which cannot burn without additional air and which rises upwardly within said recess to said upper level while unburned, and then mixes with external air and burns entirely at or above said upper level.
