Introduction What is the difference between a gas turbine power plant and a natural gas power plant? Compare the two and explain it, and you will understand: the main equipment of a gas turbine unit includes a gas turbine, a steam turbine and a generator.

What is the difference between a gas turbine power plant and a natural gas power plant?

Compare the two and explain, and you will understand:

The main equipment of the gas turbine unit includes a gas turbine, a steam turbine and a generator. There is no boiler (except for small ones). -capacity of waste heat boilers). The gas is burned in the combustion chamber of the gas turbine to do the work, it also drives the steam turbine to run the generator. The power generation capacity of the entire unit includes the capacity of the gas turbine itself. and the capacity of drag steam turbine, so it is also called a steam-gas combined cycle unit;

Natural gas generator set is also called LNG power plant. The main equipment is the same as that of the LNG power plant. a general thermal power plant, except that the boiler fuel changes from coal, fuel oil or coal gangue to natural gas,which is also a clean energy source. However, the combustion of fuel itself does not directly generate electricity, but still heats energy. superheated steam. Promote turbines and steam generators to produce electricity.

What is gas used for?

20 years. Most of the lifespan of gas-fired combined cycle power plants is 20 years. The working principle of the power plant is that the combined cycle power plant converts the thermal energy of fuel into electrical energy through the joint operation of gas turbines and steam turbines. . It is characterized by efficiency under various loads, its harmful emissions and cooling water consumption are significantly reduced.

Which of the gas internal combustion engines, gas turbines and gas boilers with steam power generation technology is the most advancedce.

Natural gas can mainly be used for the production of electricity. Waste emissions. the level of gas turbine power plants using natural gas as fuel is much lower than that of coal and oil-fired power plants have high power generation efficiency, low construction costs and fast construction speed. Additionally, gas turbines have rapid start-up and start-up; stopping speeds, strong peak shaving capabilities, low water consumption and space saving.

Natural gas is also used as a chemical raw material. The main processed products using natural gas as raw material mainly include almost. 20 varieties such as synthetic ammonia, methanol and carbon black. Important chemicals after secondary or tertiary treatment include formaldehyde, acetic acid, carbonate of dimethyl, etc. More than 50 varieties of chemical production equipment using natural gas as raw material save investment. low energy consumption, takes up less space, requires fewer personnel, is environmentally friendly and has low operating costs.

Natural gas is widely used in civil gas stoves and commercial, water heaters, heating and refrigeration are also used. in papermaking, metallurgy, quarrying, ceramics, glass and other industries. They can also be used for incineration, drying and dehydration of waste.

Gas internal combustion engines are reciprocating, similar to a car engine. The power generation efficiency (total energy conversion) of gas internal combustion engines can currently reach between 41 and 43 percent. The power of aThe single machine varies from 30 kW to 2,000 kW. Of course, there are higher horsepower machines as well, but they are all medium speed machines with an RPM of less than 1500. There are brands Cummins, Carter, Jenbacher and others. Power generation by gas internal combustion engine can fully and efficiently utilize energy. The high temperature exhaust gas can produce air conditioning cold water or domestic hot water through lithium bromide or exchanger, and the high temperature cylinder liner water can also be fully utilized. The basic energy utilization rate is not less than 82%. At the same time, it has good gas adaptability. Natural gas, coalbed methane, landfill gas, etc. can be used as efficient gas sources provided they meet a certain methane rating. Currently, it is widely used in procurement projects.Distributed energy supply/CCHP.

Gas turbine power generation efficiency (total energy conversion) is about 30%, and the current power ranges from hundreds of KW to tens of MW. There are brands such as Kawasaki, Solar, ABB and Siemens. Since the rpm can reach tens of thousands of revolutions, a large amount of high temperature steam can be generated, but the amount of hot water is very small. The use of waste heat is mainly in the form of waste heat boilers and lithium bromide. Likewise, the adaptability to the air source is relatively good, but the ambient temperature has a great impact on the power output. Compared with gas internal combustion engines, they have the advantages of small size and high power density. However, the one-time investment and maintenance cost throughout the life cycle of the equipmentipement are much higher than those of internal combustion units.

It is basically impossible to compare gas boilers with steam power generation and the above two types together. Regardless of the application environment or power requirements, they are not comparable choices for the same application.

In terms of technology, gas turbines are the most advanced. After all, there is no such thing as a “copied” version of the high-power turbine.

Finally, there is no more advanced, only the most applicable. The analysis must be carried out based on your actual situation, especially if your request is CCHP.
