1. An absorption refrigeration system burner and generator assembly comprising:
- a) a centrally positioned and vertically oriented boiling pot member having a generally uninsulated lower portion but with an insulated bottom and an uninsulated upper portion;
b) a generally annular and insulated primary combustion chamber means surrounding said boiling pot means surrounding said boiling pot means uninsulated lower portion;
c) a generally annular enclosed secondary combustion chamber means surrounding said boiling pot means upper portion in contiguous relation to said primary combustion chamber means;
d) refrigeration solution preheater means situated in said secondary combustion chamber means in a surrounding and spaced-apart relationship to said boiling pot means upper portion;
e) fuel gas/air supply and ignitor means cooperating with said primary combustion chamber means; and
f) outlet means positioned generally centrally in said boiling pot means uninsulated lower portion insulated bottom to flow relatively concentrated refrigeration solution from within said boiling pot means without periodic slugging,said fuel gas/air supply and ignitor means being positioned and oriented to cause fuel gas/air mixtures supplied to said primary combustion chamber and ignited to combust along a spiral path which surrounds said boiling pot means lower portion and which passes in said secondary combustion chamber means between said refrigeration solution preheater means and said boiling pot means upper portion.

Abstract
An absorption refrigeration system generator assembly is provided with a centrally positioned, generally vertical boiling pot element having a lower portion and an upper portion, with an annular primary combustion chamber surrounding the boiling pot element lower portion exclusive of the boiling pot member bottom surface, and with an optional contiguous secondary combustion chamber surrounding the boiling pot element upper portion. An included fuel/gas air supply and ignitor cooperates with the primary combustion chamber and causes combustion products to swirl over the lower and upper portions of the boiling pot element.
