The vapor generator employs a convection heating surface in the gas flue upstream of the superheater heating surface in the exhaust gas flow. The burners for the different fuels are disposed in a common horizontal plane in the combustion chamber. In one embodiment, one water separator is disposed between the evaporator and convection heating surfaces while a second water separator is disposed between the convection and superheater heating surfaces. In another embodiment, one separator only is used with a change-over circuit means to connect the separator either between the evaporator and convection heating surfaces or between the convection and superheater heating surfaces. |
