ABSTRACT:
A boiler comprises a water-carrying housing of sheet steel and a thin-walled cast iron casing arranged within the housing and having regions connected by condensate which are not machined. The casing includes a plurality of radial webs cast on the casing and supporting a sleeve defining a combustion chamber for the combustion of fuel. A guide chamber and a collecting chamber are defined by the casing adjacent opposite ends of the sleeve, the guide chamber being arranged to receive the combustion gases from the combustion chamber and the webs defining therebetween flow ducts connecting the guide and collecting chambers for conducting the combustion gases to the collecting chamber. The casing extends beyond the two end walls of the housing and the end walls form a liquid-tight connection with the casing. The webs extend into the guide and collecting chambers, the height of the web portions in the guide and collecting chambers not exceeding that of the web portions supporting the sleeve.
