Abstract
Abstract A method and apparatus for reducing the formation of fog by exhaust gases entering the atmosphere from apparatus which includes an immersed combustion heater. The method comprises cooling the exhaust gases prior to their entry into the atmosphere so as to remove water vapour, the cooling being, for instance, by spraying water in a direction against the gas flow in an exhaust stack.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
52 words
A method of reducing the formation of fog by exhaust gases entering the atmosphere from apparatus which includes an immersed combustion heater, .characterised in that the method comprises cooling said exhaust gases prior to the entry of the gases into the atmosphere, so as to remove water vapour carried by said gases.
Claim 2
Independent Claim
52 words
A method of reducing the formation of fog by exhaust gases entering the atmosphere from apparatus which includes an immersed combustion heater, .characterised in that the method comprises cooling said exhaust gases prior to the entry of the gases into the atmosphere, so as to remove water vapour carried by said gases.
Claim 3
Dependent Claim
20 words
A method according to claim 1 characterised in that the apparatus is for the heating or vapourisation of cryogenic fluids.
Claim 4
Dependent Claim
31 words
A method according to claim 1 or claim 2 characterised in that said cooling of said exhaust gases is by contacting said exhaust gases with a fluid of a lower temperature.
Claim 5
Dependent Claim
13 words
A method according to claim 3 characterised in that said fluid is water.
Claim 6
Dependent Claim
21 words
A method according to claim 3 or claim 4 characterised in that said fluid is in the form of a spray.
Claim 7
Independent Claim
32 words
A method according to any of claims 3 to 5 characterised in that said exhaust gases flow substantially upwardly along an exhaust stack while said cooling fluid flows downwardly along said stack.
Claim 8
Independent Claim
41 words
A method-according to any of claims 3 to 6 characterised in that said fluid, after contacting the exhaust gases in the stack, is fed from the stack, cooled and then returned to the stack to effect further cooling of exhaust gases.
Claim 9
Independent Claim
36 words
A method according to any of claims 3 to 7 characterised in that said exhaust gases are discharged from the exhaust stack through a moist eliminator to prevent the carrying into the atmosphere of entrained moisture.
Claim 10
Dependent Claim
41 words
Apparatus for the heating or vapourisation of cryogenic fluids characterised in that it comprises an immersed combustion heater and means for cooling the exhaust gases before discharge to the atmosphere so as to remove water vapour carried by said exhaust gases.
Claim 11
Dependent Claim
41 words
Apparatus for the heating or vapourisation of cryogenic fluids characterised in that it comprises an immersed combustion heater and means for cooling the exhaust gases before discharge to the atmosphere so as to remove water vapour carried by said exhaust gases.
Claim 12
Dependent Claim
42 words
Apparatus according to claim 9 characterised in that the apparatus includes an exhaust stack up which the exhaust gases are caused to flow and said cooling means comprise means for spraying water within said stack against the flow of the exhaust gases.
