How much water does an 8,000 kilowatt hydroelectric generator use?

Introduction How much water does an 8,000 kilowatt hydroelectric generator use? An 8,000 kilowatt hydroelectric generator uses 355 million cubic meters of water. Used for hydroelectric power generation per unit of 4 × 2000 kW = 8000 kW

How much water does an 8,000 kilowatt hydroelectric generator use?

An 8,000 kilowatt hydroelectric generator uses 355 million cubic meters of water.

Water used for hydroelectric power generation of units 4 × 2,000 kW = 8,000 kW, the average water consumption for many years is 355 million meters cubic, so the 8,000 kW hydroelectric generator uses 355 million cubic meters of water. water.

A motor refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction.

How to calculate the water consumption of a hydroelectric plant?

0.6 kg/kWh

The power generation water consumption rate of the unit parameter of 300,000 kilowatts should refer to the rate of water consumption of the unit 300,000 kilowatts of the unit. thermal power plant, excluding hydraulic evacuation of ashes, cooling water ofauxiliary equipment, coal yard water, domestic water, etc., but refers to the normal water replenishment of the unit circulation cooling system and the boiler water replenishment.

Therefore, according to the requirements of 14.1.4 of “Technical Regulation DL 5000-2000 for the design of thermal power plants”, the rate of water consumption for electricity production should not exceed design regulations. However, in the actual production process, based on various production management factors, the water consumption rate for power generation generally evolves towards the first-rate thermal power plant management indicators. According to relevant reports, the water consumption rate of the best water-saving generator per unit of power generation can reach less than 3.6 kg/kWh. Of course, this is related to the unit type.

Detailed Information

Shanghai Heavy Machinery Factory Co., Ltd. and others are responsible for high and medium pressure cylinder trial production, forming fusion, casting, heat treatment, welding repair, etc. Complete production process, the product was used in a 600MW steam turbine.

After many failures in the development of high-voltage rotors, we finally solved the problem of smelting high-alloy low-silicon and aluminum steels, developed under-slag remelting technology Nitrogen protected electric and successfully tested- produces one high voltage rotor, two rotors for the product in production. Austenitic stainless steel pipe is developed by the special steel branch of Baoshan Iron and Steel Co., Ltd. and participated by Shanghai Boiler Works Co., Ltd. The metallurgical quality of the national pipe is equivalent to the level of materialsimported materials, and the durable strength can reach 99 MPa at a high temperature of 650°C.

High temperature and high strength materials for blades and bolts developed by Shanghai Steam Turbine Co., Ltd. and others have been industrialized, with an annual production of around 600 tons. Generators installed with this component in power plants such as Huangdao in Shandong and Suxian in Anhui have been put into normal operation. The high-strength screw material for turbine generators developed by Shanghai Xinmin Heavy Forging Co., Ltd. and others has been used successfully in 1000 MW generators.

According to expert estimates, once the project is completed, the cost of ultra-supercritical units could be reduced by half. The outline of China's "eleventh five-year plan" proposes "to optimize the development of thermal energy by placing emphasis on unitslarge-scale, high-efficiency and environmentally friendly, and build large-scale ultra-supercritical power plants and large-scale air-cooled power plants. The "Medium and Long-Term National Scientific and Technological Development Plan" clearly lists energy as a priority area of ​​development, and in "coal cleaning"Technologies such as ultra-supercritical units with high parameters are clearly proposed in the theme "Clean and efficient development and utilization, liquefaction and polygeneration".

How much How much water does a hydroelectric generator use to produce electricity?

Water consumption per second = N/H/K (cubic meters)

N—— Power of hydroelectric power station (KW)

H——Rated head of hydroelectric power station(meter)

K——Output coefficient: 8.0~8.5 related to the efficiency of the unit

For example: a hydroelectric power station Water height nominal H = 100 meters When electricity generation is 1000 kW, water consumption per second = 1000/100/8.2 = 1.22 (cubic meters), water consumption per hour = 4390 cubes. meters and water consumption per day is 105,000 cubic meters. < /p>

What is the water consumption for electricity production

The air pressure is 0.8 MPa, which is equivalent to a water height of 80 meters. In general, it can be estimated that 6.5 cubic meters of water can generate one kilowatt hour of electricity. That is, when 40 cubic meters of water are used, 6.15 kilowatt hours of electricity can be generated (take 6 kilowatt hours). , that is, 2KW can be used for 3 hours. The principle is that the air pressure must be kept constant. In fact, the power you use to pomper must be much higher than the power generated by the generator, right.

Definition: Refers to the amount of water consumed per unit of energy generated by a hydroelectric power plant

Purpose: Mainly used for turbine condenser cooling, lubrication and cooling of various auxiliary engines . system water, water for ash disposal and water supply for power generation boilers. The water consumption of 1 G megawatt per hour is the water consumption for electricity production. In order to reduce water consumption for electricity generation, the state has strict restrictions on water consumption. /p>

Calculating the water consumption rate: The water consumption rate is the amount of water flowing through the turbine for each kilowatt of electricity produced and constitutes a important parameter characterizing the efficiency of the generator.

1. The average rate of water consumption is equal to the volume of water divided by the volume of electricity

2 The water volume can be determined by installing a flow meter on the turbine and integrating the flow rate with time to obtain the water volume. The electric quantity can be checked from the electric meter;

3. Real-time water consumption rate is equal to flow divided by power
