ABSTRACT:
A boiler comprises a shell for fluid to be treated and divided into first and second heat exhange zones by at least one baffle, the zones being in communication with one another beneath a lower end of the baffle. Exhaust gases from a combustion source are supplied to a plurality of heat exchange tubes extending through each zone in heat exchange relationship with the fluid in the shell and being arranged in passes sequentially connected to one another whereby the exhaust gases pass sequentially through the first and second zones. The fluid to be heated is fed to an upper region of the second zone such that the temperature of gases passing through at least some of the tubes in the second zone falls to below the dew points of combustion products therein, the tubes in which condensation occurs being orientated such that condensates flow therefrom for disposal.
