Boiler water return, ventilation and cooling.
A thermal power plant, called a thermal power plant, is a factory that uses coal, oil and natural gas as fuel to produce electrical energy. Its basic production process is as follows: fuel is burned in the boiler. and the heated water is converted into steam, and the chemical composition of the fuel is converted into steam, the energy is converted into thermal energy, the pressure of the steam drives the rotation of the steam turbine, the thermal energy is converted into mechanical energy, then the heated water is transformed into steam. The steam turbine drives the generator to rotate, converting mechanical energy into electrical energy.
What is the function of cooling tower in thermal power plant?
Shanghai Taiyi Cooling Tower Factory will answer for you:
S This is a cooling systemnewly purchased tower, the effect should be The flow rate is too low.
If it was used well at the beginning, the cooling tower may have been used for a long time and there is a lot of waste blocking the cooling tower.
Analysis of the reasons for insufficient cooling effect of cooling towers:
1. The valve is too large, resulting in excessive circulating water volume or inadequacy in the selection and purchase of the cooling tower;
p>
2. Part of outlet holes of the water distribution pipe are blocked, causing deviation
3. The ventilation pipe is blocked, resulting in insufficient ventilation, or the fan speed is low;
4. Filling is partially blocked, causing deviation;
Solutions to insufficient cooling effect of cooling tower:
1. appropriate amount of water, or replacez the cooling tower by a corresponding capacity;
2. Remove the blockage in the water distribution pipe
3. Clean the ventilation duct, adjust the fan size; or increase fan speed;
4. Remove filling blockage or change water spray filling structure of cooling tower
The cooling tower of a thermal power plant is a problem. device used to cool the heat generated during the electricity generation process. In thermal power plants, thermal energy is usually generated by burning fuels (such as coal, natural gas, etc.), and then the thermal energy is converted into steam through a boiler to drive a turbogenerator to produce electricity. During this process, the combustion of fuel will generate a large amount of heat, and the operation of the generator will generatealso a large amount of heat, which will need to be dissipated through the cooling tower to maintain normal operation of the equipment.
Specifically, the cooling tower of a thermal power plant mainly reduces the water temperature through water circulation and heat dissipation through evaporation, thereby dissipating heat. The water from the cooling tower will be transported to the top of the tower by the water pipe, then atomized into small water droplets through the nozzle and enter inside the tower with the airflow . Inside the tower, the water droplets are in full contact with the air, dissipating heat through evaporation, dissipating heat, and the water temperature gradually drops. Through the wrapping layer inside the tower body, the contact area between water droplets and air is increased, thereby improving the heat dissipation effect. THEThe cooled water returns to the pool again, is pumped by the circulation pump, and then enters the tower body again for circulation cooling. Through this cyclic process, the cooling tower can dissipate heat to ensure the normal operation of the thermal power plant equipment.
