太阳能热力发电技术进展

太阳向地球辐射无尽的能源。虽然到达地球表面的太阳辐射随时间变化并受天气影响给太阳能的利用带来的一些技术难题，但是太阳能丰富易得，利用过程须付出环境代价，这些常规能源无法与之相比的优点必将使其成为２１世纪的一种重要能源。

TECHNOLOGY PROGRESS IN SOLAR THERMAL POWER GENERATION

The sun radiates endless energy to the earth. Though the solar radiation reachingthe earth's surface changes with the table and weather, which brings some difficulties to utilization of solar energy I solar energy is abundant and easily available,and there is no need to pay anyenvironment cost for use of it. These advantagies, at which the conventional energies can notmatch ie, are bound to make it a kind of the global important enerdies in 21st century. This papergives an overview of the development of solar thermal power generation plants, the solar thermalpower stations combined with use of natural gas) and the chemical storage energy system for thesolar thermal power station.Some significant progresses in this field is covered as well.
