Abstract

The invention discloses a steam generating device for a high-power solar-thermal power station, and relates to the field of electric power and chemical engineering systems. The device solves the problems that traditional kettle-type reboilers used by existing high-power heat exchange power stations are difficult to manufacture with high cost and low steam quality. A steam drum of the device is horizontally mounted above an evaporator A and an evaporator B in a parallel mode. One end of the steam drum is provided with a feed-water inlet, and the feed-water inlet is communicated with a water storage area of the steam drum. The upper part of the steam drum is provided with a plurality of steam outlets along the axis of the steam drum. The water storage area inside the steam drum is respectively communicated with the upper parts of the evaporator A and the evaporator B through a plurality of downward pipes. The bottoms of the evaporator A and the evaporator B are respectively communicatedwith a steam-water separation area inside the steam drum through a plurality of upward pipes. Air outlets formed on the steam-water separation area are communicated with the steam outlets formed on the steam drum. Water outlets formed on the steam-water separation area are communicated with the water storage area inside the steam drum. The device is used for realizing natural steam circulation under a non-heated state of the upward pipes.

Description

technical field [0001] The invention relates to the field of electric power and chemical industry systems, in particular to a steam generating device for a high-power photothermal power station. Background technique [0002] Energy and environmental issues are two important issues facing the world today. In recent years, my country has always attached great importance to the development and utilization of new energy sources. Among them, the use of solar power generation is an effective way to alleviate or even solve energy problems. Countries around the world are also actively doing s hard work. The solar-thermal power generation steam generation system is an important heat exchange equipment, and the steam generation device is a main component of the equipment. Its function is to convert the nearly saturated water heated by the preheater into saturated steam through heat exchange. The solar-thermal power station mainly adopts a kettle-type reboiler, but if a kettle-type reb...
