The method comprises: (a) pressurising a working fluid liquid comprising water to a first pressure; (b) heating the working fluid liquid to a temperature substantially equal to the saturation temperature of the working fluid liquid at the first pressure; and (c) flash evaporating the working fluid liquid to generate steam. The pressurised working fluid liquid is heated in step (b) by direct heating in a solar radiation absorption device. Also disclosed is an apparatus for generating steam for use in an industrial process. The apparatus comprises a pump (32) for pressurising a working fluid liquid comprising water to a first pressure; a heating unit (34) downstream of the pump (32) for heating the working fluid liquid to a temperature substantially equal to the saturation temperature of the working fluid liquid at the first pressure; and a cooperating throttle valve (36) and flash tank (38) downstream of the heating unit (34) for flash evaporating the working fluid liquid to generate steam. The heating unit (34l ) comprises a solar radiation absorption device for direct heating of the pressurised working fluid.

摘要： A method for increasing the operational flexibility of a turbomachine during a shutdown phase is provided. The turbomachine may include a first section, a second section, and a rotor disposed within the first section and the second section. The method may determine an allowable range of a physical parameter associated with the first section and/or the second section. The method may modulate a first valve and/or a second valve to allow steam flow into the first section and the second section respectively, wherein the modulation is based on the allowable range of the physical parameter. In addition, the physical parameter allows the method to independently apportion steam flow between the first section and the second section of the turbomachine, during the shutdown phase.
