A shop assembled modular steam generator wherein each module includes top supported pressure parts, casing, and a frame structure. These modules are readily transported to a remote construction site and interconnected. Each of the superheater, high pressure boiler, intermediate pressure boiler, low pressure boiler, and economizer sections of the generator comprise separate center and end modules whose casings are joined to provide a gas tight flow path around the pressure parts.
