用于产生供在工业过程中使用的蒸汽的方法和装置
Abstract:
本发明公开了一种用于产生供在工业过程中使用的蒸汽的方法。所述工业过程可以例如为发电或脱盐。所述方法包括：(a)将含有水的工作流体液体加压至第一压力；(b)将所述工作流体液体加热至大致等于所述工作流体液体在所述第一压力下的饱和温度的温度；以及(c)将所述工作流体液体闪蒸以产生蒸汽。通过在太阳辐射吸收器件中直接加热而在步骤(b)中加热所述加压的工作流体液体。本发明还公开了一种用于产生供在工业过程中使用的蒸汽的装置。所述装置包括用于将含有水的工作流体液体加压至第一压力的泵(32)；位于所述泵(32)下游的用于将所述工作流体液体加热至大致等于所述工作流体液体在所述第一压力下的饱和温度的温度的加热单元(34)；以及位于所述加热单元(34)下游的用于将所述工作流体液体闪蒸以产生蒸汽的协同操作的节流阀(36)和闪蒸罐(38)。所述加热单元(34)包括用于对所述加压的工作流体直接加热的太阳辐射吸收器件。
Abstract(English):

A method of generating steam for use in an industrial process is disclosed. The industrial process may for example be power generation or desalination. 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 (34) comprises a solar radiation absorption device for direct heating of the pressurised working fluid.
