Natural gas power generation and exhaust treatment

Page view
A gas turbine is a rotating machine that converts thermal energy into mechanical work, including a compressor (generally referred to as a compressor in a gas turbine), a device that heats a working fluid (such as a combustion chamber), a turbine, a control system, and ancillary equipment; Air is generally quoted as a working fluid. Gas-fired power generation is one of the most stable distributed energy supply methods. The excellent cold-heat power triple power generation system can increase the efficiency of gas-fired power generation to over 95%.
Technology Introduction
Technical advantages

A gas turbine is a rotating machine that converts thermal energy into mechanical work, including a compressor (generally referred to as a compressor in a gas turbine), a device that heats a working fluid (such as a combustion chamber), a turbine, a control system, and ancillary equipment; Air is generally quoted as a working fluid. Gas-fired power generation is one of the most stable distributed energy supply methods. The excellent cold-heat power triple power generation system can increase the efficiency of gas-fired power generation to over 95%.

High thermal efficiency: Natural gas power generation has high thermal efficiency. At present, the "G" and "H" grade gas turbines that have been introduced or under development by major companies have an initial gas temperature of 1427 ° C, a simple cycle capacity of 280 MW, a combined cycle capacity of 520 MW, and a thermal efficiency of over 60%.
Investment province: The installed capacity of natural gas power generation requires less investment and is cheaper. At present, the investment cost per kilowatt is only 4,000-5,000 yuan/KW, or even lower, and the investment in steam turbine power plants is currently as high as 8,000-11,000 yuan/KW. .
The construction period is short: its equipment is composed of components, light weight and fast construction. It can be put into operation in 12~20 months, generally 43% of the construction period of thermal power units. Because of the less civil construction, it can be constructed in stages, first building gas turbines. The power plant will rebuild the combined cycle power plant to maximize capital efficiency.
The area is small, generally 50% of coal-fired power plants; water consumption is only about 30% of coal-fired power plants.
Reliable operation, high degree of automation, and greatly reduced operating personnel. The daily operational management required is only 2% of the average coal-fired power plant.
