Regarding the main equipment of power plants
Thread Content
Just letting you know in advance – I’m not sure if this post should be posted in this forum. If it’s not appropriate, please ask the moderators to help move it to the right place. Thank you. Regarding the main equipment in power plants, I was wondering if any of you have detailed diagrams of the various buildings in a power plant, so that those who are new to this field can understand what they are seeing. It would be great to spread some knowledge on this topic; thank you in advance to those who share such information! :lol
The three main equipment in a power plant are the boiler, turbine, and generator; everything else are auxiliary devices such as pumps, pipes, valves, and instruments. The facilities mainly include the main plant area, power distribution area, cooling system area, coal combustion facility area, auxiliary production area, and buildings in front of the plant. The actual layout plan is not available to the public.

As mentioned above, the equipment and systems in a power plant that are directly related to production include the turbines, boilers, generators and their auxiliary systems, as well as the chemical water system, coal conveying system, and circulating cooling water system (which belongs to the turbine system). The specific layout is as follows: From Column A to Column B in Building A lies the turbine room, where equipment for the turbine and generator systems is installed, including the main turbines and generators, high- and low-pressure heaters, condensers, condensate pumps, feedwater pumps, various steam pipes and water pipes such as main steam pipes, extraction steam pipes, reheat steam pipes, bypass systems, circulating cooling water system pipes, feedwater and condensate system pipes, the main oil tank, and various oil pumps, etc； Between Column B and Column C is the coal bin deaeration room, where the raw coal bin, coal feeder, deaerator, and various pipes connected to the deaerator are located. There are also vertical downward pipes for main steam and reheat steam. The main control system is also placed in this coal bin deaeration room, usually on the lower level of the deaerator; below the control room is a cable tray, and further down is the zero-meter level, on which the coal grinding equipment is installed ； The space between Column C and Column D is the boiler room; no further details are needed. Behind the boiler room are, in sequence, the dust collector, the exhaust fan, and the chimney; there are also equipment for desulfurization and denitrification systems. Further back is the raw coal yard, which will not be described further. Outside Column A of the turbine room, the main transformer, circulating water pump, and circulating water cooling tower are arranged in sequence.
Main equipment of power plants: boiler system, generator system, power grid transmission system
The main systems of a power plant are: the steam and water system, the combustion system, the control system, and the electrical system – four major sections in total
