槽式太阳能光热电站辅助锅炉选型研究

Research on Auxiliary Boiler Selection for Trough Solar Thermal Power Plant

辅助锅炉是光热电站不可或缺的辅机设备,与机组的启动耗时和运行安全息息相关。由于行业发展时间较短,我国现阶段并未就光热电站辅助锅炉的选型形成统一标准。针对槽式光热电站的运行特点,针对某槽式光热电站辅助锅炉的蒸汽参数和容量选择进行了研究。结果表明:可以在保证机组安全启停和运行的前提下,降低辅助锅炉的设计容量,节省投资。

Auxiliary boiler is an indispensable auxiliary equipment in solar thermal power plant, which is closely related to the start-up time and operation safety of the unit. Due to the short development time of this industry, there is no unified standard for the selection of auxiliary boilers for solar thermal power plants in China at present. Here we analyze the operation characteristics of the trough solar thermal power plant and study the steam parameters and capacity selection of auxiliary boiler in a certain trough solar thermal power plant. The results show that this research can reduce the design capacity of auxiliary boilers and save investment on the premise of ensuring the safe start-up and shutdown and operation of units.
