Hydroelectricity is limited by natural conditions. There are only a few large rivers in China, and they require large breaches and qualified addressing conditions, so there are fewer large-capacity options. Thermal power plants are mainly made of metal and are much easier to build. They can be built with as large a source of coal as possible. Beilun Power Station, Tuoketuo, Ligang Power Station, Zouxian Power Station and other important thermal power stations are all less than 300. More than 10,000.
Thermal power stations and thermal power plants are two different ways of producing electricity. Their main differences, advantages and disadvantages are as follows:
Main differences:
.1. Fuel type: Thermal power plants mainly use fossil fuels (such as ccoal, natural gas, etc.) to burn and produce electricity, while thermal power plants use non-fossil fuels such as nuclear energy, solar energy and geothermal energy to produce electricity .
2. Method of generating electricity: Thermal power plants generate steam at high temperature and high pressure by burning fuel to drive the steam turbine to produce electricity. Thermal power plants use nuclear or other thermal energy to generate directly; steam to drive the steam turbine to produce electricity.
3. Environmental impact: Thermal power plants burning fossil fuels will produce large amounts of carbon dioxide, nitrogen oxides, sulfur oxides and other air pollutants, which will have a greater impact on the use of thermal power plants; fuels nwe fossil and emit fewer pollutants and less impact on the environment.
Advantages and disadvantages:
Advantages of thermal power plants:
1. Abundant fuel resources: Fossil fuel resources are relatively abundant and thermal power plants can use these resources to generate electricity.
2. High power generation efficiency: The power generation efficiency of thermal power plants is relatively high, and can reach more than 40%.
3. Low power generation costs: The construction and operation costs of thermal power plants are relatively low.
Disadvantages of thermal power plants:
1. Environmental pollution: The combustion of fossil fuels in thermal power plants will produce a large amount of air pollutants, having a serious impact on the environment.
2. Gas emissionsGreenhouse: Thermal power plants emit large amounts of carbon dioxide and other greenhouse gases, exacerbating the problem of global climate change.
3. Energy consumption: Thermal power plants require a large amount of fuel and consume a large amount of energy resources.
Advantages of thermal power plants:
1. Environmentally friendly: Thermal power plants use non-fossil fuels, emit fewer pollutants and have less impact on the environment.
2. Sustainable use of energy: The thermal power plant uses nuclear energy, solar energy and other renewable energy sources to generate electricity, which has the characteristics of sustainable use.
3. High power generation efficiency: the thermal power plant uses high temperature and high pressure steam to directly drive the turbine steam in order to generate electricity, and the efficiency of electricity generation is high.
Disadvantages of thermal power plants:
1. High fuel costs: The cost of non-fossil fuels is relatively high, and the fuel cost of thermal power plants is also high.
2. High Construction Costs: The construction costs of thermal power plants are relatively high and require significant capital investment.
3. Safety Risks: There are certain safety risks when thermal power plants use special energy sources such as nuclear power.
