One kilowatt hour of electricity can power a 25-watt desk lamp lit for a full 40 hours. This is a great comfort to students who stay up all night and office workers who stay up late to work overtime.
You can charge your phone more than 100 times with a single battery. You can read novels, play games and watch videos as you like without worrying about the embarrassment of low battery.
One kilowatt hour of electricity allows a 66-watt refrigerator to run for 15 hours, allowing you to easily enjoy fresh ingredients, frozen fruits and refreshing cold drinks.
There are many things that can be done with one kilowatt hour of electricity, such as boiling 8 kilograms of water, running the air conditioner for 1.5 hours, irrigating 0.14 acres of wheat , produce 15 bottles of beer, and faire of the electric bike for 80 kilometers.
A kilowatt hour of electricity represents a very small existence. According to Beijing's current charging standards, the cost of one kilowatt hour (one kilowatt hour) of electricity is 0.4883 yuan. Don't underestimate the cost of less than 50 cents per kilowatt hour of electricity. It takes a lot to produce that kilowatt hour of electricity. At present, the main methods of electricity generation are thermal power generation, hydroelectric power generation, nuclear power generation and wind power generation.
As for the most common thermal power generation method currently, thermal power generation mainly uses coal to produce electricity by burning it. As a model for burning himself and giving back to society, he consumes 310 grams of charcoal and 4 liters of purified water, and must consume 190 grams ofdiesel and 59 grams of natural gas to produce one kilowatt hour of electricity.
With this kilowatt hour of electricity comes 160 grams of carbon dioxide, 272 grams of carbon dust, 6.2 grams of sulfur dioxide, 15 grams of carbon oxides and other harmful ingredients for the environment.
A steam turbine, also called a steam turbine engine, is a rotating high-temperature, high-pressure steam device that passes through a fixed nozzle and becomes an air stream accelerated, then. is sprayed onto the blades, causing the rows of blades to move. The rotor rotates and at the same time does work externally. Steam turbines are the main equipment of modern thermal power plants and are also used in the metallurgical industry, chemical industry and ship power plants.
The operating principle of a steam turbine:
A steam turbine ist an externally combustion rotary machine that can convert the thermal energy of steam into mechanical work. Once the steam from the boiler enters the steam turbine, it passes through a series of annularly arranged nozzles and moving blades, converting the thermal energy of the steam into the mechanical energy of rotation of the turbine rotor . The steam converts energy in different ways in the steam turbine, thus forming steam turbines with different operating principles.
