Abstract
A 'package-type' boiler fired by pulverized coal that is adapted to be constructed and assembled in a shop then shipped as a completed unit to a given plant site. The boiler is provided with tube walls extending between longitudinally disposed drums that simultaneously provide optimum heat transfer along with internal support. The walls are bent to a configuration that imparts to the boiler a hopper-shaped bottom wall on opposite sides of an elongate throat through which solid products of combustion may be discharged.
