Feng Wuhuang Bai Jishan Kitty [Scholar] Thermal power generation
1 Utilizes the heat energy generated when solid, liquid, and gaseous fuels such as coal, oil, and natural gas are burned to generate power through power generation devices (including power plants) A method of generating electricity that converts boilers, steam turbines, generators and their auxiliary devices into electrical energy.
2 Among all power generation methods, thermal power generation has the longest history and is also the most important.
3 The emergence of the power system and the demand for electric energy from social electrification must be realized through thermal power generation (an important issue in thermal power generation is to improve thermal efficiency, by increasing the parameters of the boiler (steam pressure and temperature) . In the 1990s, the world's best thermal power plants could convert about 40% of thermal energy into electrical energy; the thermal energy utilization rate of large heating power plants could only reach 60% to 70%)
4 Shortcomings: thermal power. Power generation uses a large amount of coal and fuel oil, causing environmental pollution.
1. Wind power is non-polluting and easy to use
2. Advantages of wind power generation Wind power stations save money than other power stations. The disadvantage is that offshore power is too small and distant seas cannot be built. Power station
3. Disadvantages: However, if the wind is too strong, such as a typhoon or tornado, it will cause damage to national property; the advantage of wind power is that solar power generation will be affected when the weather is bad, but wind power will The stronger the wind, the better the power generation (but not too big)
There are time and season restrictions. They all have limitations and timeliness, seasonality!
I would like to ask Gaoren whether there is a "limited space" in the wind farm. If so, how are the management regulations formulated?
Currently, the production processes of several major power plants are as follows:
1. Thermal power plant
Boiler: chemical energy of fuel → thermal energy of flue gas → Steam thermal energy
Steam turbine: steam thermal energy → mechanical energy
Generator: mechanical energy → electrical energy
The overall production process: chemical energy of fuel → thermal energy → mechanical energy → electrical energy
2. Hydropower plant
The basic process of energy conversion in a hydropower plant is: water energy → mechanical energy → electrical energy
3. Nuclear power plant
< p>The basic process of energy conversion in nuclear power plants: atomic energy → thermal energy → mechanical energy → electrical energy4. Wind power plant
The working principle of wind turbines is relatively simple. The role of wind turbines in wind power By rotating downward, it converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind turbine shaft.
What do you mean by limited space?
There should be no completely enclosed space, but some power plants have SF6 switch rooms. If SF6 leaks, the oxygen content in the air will decrease. There is also a situation where the space inside the fan tower barrel is small and relatively closed, making it inconvenient to get in and out. Generally, wind farms do not have pressure vessels or boilers, but they may have gas tanks, oil storage and other places. Management regulations vary depending on the site. For example, you must wear safety equipment when working inside the tower barrel.Wear a hat, wear a safety belt, and correctly use the anti-fall device. Do not open live panel cabinets at will. When climbing, one person can pass through each level. Prevent falling objects from injuring people, etc.
