【摘要】 介绍了一种太阳能烟囱发电新技术。太阳光辐射透过太阳能集热棚,加热集热棚下面的地面,被加热的地面与集热棚内的空气进行热量交换,使其温度上升,被加热的空气上升并进入与集热棚中部相连的烟囱,在烟囱内上升气流推动涡轮发电机旋转、发电。整个太阳能烟囱发电技术的能量转化以及效率可以从三个部分来分析:通过集热棚太阳能转化为空气热能,通过烟囱将热能转化为动能,通过涡轮发电机将动能转化为电能。另外,总结了太阳能烟囱发电技术的优缺点,指出它是一种适合于我国西部地区的一种能源开发新途径。更多还原

【Abstract】 A solar chimney thermal electricity generating system was introduced.The radiation of the sun passes through the solar collector.The sun heated the land through the solar collector array in turn,heating the air flowing.The warmer air flows up from the collector into the chimney where it turns the rotor installed in the chimney,then producing the electrical power with the generator. This solar-to-electric energy conversion and its efficiency involve three following stages: conversion solar energy into air thermal energy through solar collector,conversion thermal energy into kinetic energy by chimney,conversion kinetic energy into electric energy by the wind turbine generator.Furthermore,this energy technology have been discussed,and it is suited for the western area of China.更多还原
