Abstract
A fluid fuel boiler having a combustion chamber having an opening for introducing a combustion supporting gaseous fluid. A burner introduces a liquid fuel into the combustion chamber mixed with the gaseous fluid for combustion thereof. Water-heating flow paths are disposed circumferentially and axially of the combustion chamber. Axial hot gas flow paths deliver hot gases from a downstream portion of the combustion chamber to a plurality of nozzles for diverting some of the hot gases along axially spaced paths in a direction circumferentially of the combustion chamber. These latter hot gas flow paths are immersed in the flow paths of the water to improve heat transfer. PAC BACKGROUND OF THE INVENTION This invention relates generally to boilers and more particularly to a new and improved modular boiler. It is known that the coefficient of heat transfer of a conduit for transferring heat from hot gases to water passing through a boiler is a function of the turbulence of the gases in the heat-transfer or convection conduits. In known boilers, this turbulence of the gases is relatively slight and is increased in practice only by the interposing of baffles distributed along the heat-tran…
