ABSTRACT:
A combustion chamber and liner for use in a wound boiler formed from a heat exchanger slab rolled into a plurality of wound heat exchanger convolutions, the inner heat exchanger convolutions defining a space in which a sized and shaped elongated hollow cylindrical member defining the fire box is removably mounted and in assembled position forms an inner annular combustion gas flow passage disposed to communicate with an outer combustion gas flow passage, the cylindrical member has means to position and orient the cylindrical member in assembled position so that a top inlet in the wall of the cylindrical member in association with an aligning and guide member will pass combustion gases from the fire box into the inner combustion gas flow passage, in a direction counter to the flow of combustion in the fire box, and the outer combustion gas flow passage is disposed to communicate with a suitable flue or discharge outlet to pass residual combustion gases to waste.
