<p>A combustion apparatus comprises a combustion chamber (12) having distally opposite first and second end walls (14, 16), and having a sidewall (18) extending between said end walls (14, 16), a cover (24) external to said combustion chamber (12) and covering said first end wall (14) and defining a buffer space (26) therebetween, one or more penetrations extending through said first end wall (14) between said buffer space (26) and said combustion chamber (12), a blower (32) external to said cover (24) and supplying air to said buffer space (26) and pressurizing said buffer space (26) to a higher pressure than said combustion chamber (12) such that leakage at said one or more penetrations flows from said buffer space (26) into said combustion chamber (12). <IMAGE></p> |
