How many hours is the water consumption of a thermal power plant calculated?

The water circulating in thermal power plants is divided into open cycle and closed cycle. Water consumption in closed cycle is very low. Your installation must belong to the open cycle. The amount of circulating water extracted is related to the operating time of the unit. Currently, the annual operating time of the power plant is only about 5,500 hours, so it is more reliable to calculate the water consumption at 5,500 hours.

Approximately how much water does a thermal power plant boiler evaporate per second?

Firepower:

Advantages: The technology is mature and the current cost is low. Low geographic environment requirements.

Disadvantages: high pollution, poor prospects for sustainable development. It consumes a lot of energy and has low efficiency.

Hydraulic power:

Advantages: long history, low subsequent costs. No pollution, energyrenewable water, large total water energy reserves.

Disadvantages: large capital investments and high requirements for geographical environment. For example, southwest China is extremely rich in water resources, but the natural environment is harsh and construction is difficult, making its use impossible. them.

< p>Electricity generation is to convert water energy, fossil fuel thermal energy, nuclear energy, solar energy, wind energy, geothermal energy, ocean energy and other energies into electrical energy through the use of electricity generation devices. By the end of the 20th century, most electricity generation used the method of burning fossil fuels. However, fuel resourcesFossil sources are not abundant and are becoming more and more depleted. At present, humans are gradually using renewable energies (hydraulic energy, solar energy, energy). wind energy, geothermal energy, marine energy, etc.) to produce electricity.

The basic principle of hydroelectricity is to use the difference in water level to produce electricity with a hydroelectric generator, that is, the potential energy of the water is converted into mechanical energy of the water wheel, and then into mechanical energy. mechanical energy is used to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of water level difference, effectively use fluid engineering and mechanical physics, and carefully combine them to achieve the highest power generation capacity, so that people can use an electricity cheapand pollution-free.

Thermal power generation generally refers to the use of thermal energy generated when fuels such as oil, coal and natural gas are burned to heat water, transforming the water into water vapor at high temperature and high pressure, and then use the water vapor to drive a generator to produce electricity. The general name of the method. Power plants that use coal, oil, or natural gas as fuel are collectively called thermal power plants.

This is not a fixed value, it changes when the capacity (boiler or generator) changes. The unit of capacity of a steam boiler is T/h, which corresponds to the amount of evaporation per hour and not seconds. Theoretically, it takes a ton of water to evaporate a ton of steam, which is the law of idiotservation of matter. However, because the operation of the boiler requires factors such as wastewater discharge and leakage, as well as some physical factors, the direct consumption of water to evaporate one ton of steam, i.e. consumption of water entering the boiler, is greater than the evaporation capacity, and generally does not exceed 1.2 tonnes.
