It is mainly divided into three types, 1 air cooling, 2 open water cooling, 3 closed water cooling,
1 air cooling, as the name suggests, is to use directly air for cooling, 2 Free water cooling refers to that of power plants. Water is taken from places surrounded by rivers, then passed to the condenser to absorb the heat emitted by the exhaust steam of the steam turbine, and then discharged directly into the river with a water pump 3. Water cooling closed means that water is drawn from the water source, collected, and then sent to the condenser via a water pump. The steam generator absorbs heat from the spent steam and then collects it after cooling through chillers such as cooling towers. then recycles it.
Cooling water source for high temperature sampling racksature in thermal power plants
Circulating water passes through the cooling tower. Airflow is still used to remove water. heat in the water, so the water temperature cannot be lower than room temperature.
If this is the case, it may be due to water replenishment. For example, if groundwater is used to replenish circulating water, the temperature of the water table will be much lower than the air temperature.
Sampling from rivers, lakes or deep wells. According to the thermal network query, thermal power plants use a large amount of cooling water which mainly passes through the condenser of the steam turbine to cool the spent steam into condensed water for recycling. This cooling water is called “circulating water” and comes from rivers, lakes or deep wells. Water circulating in power plantselectrical is divided into “open cycle” and “closed cycle”. The closed cycle is often used in areas where water is scarce. A thermal power plant, called a thermal power plant, is a factory that uses combustible materials (such as coal) as fuel to produce electrical energy. Its basic production process is as follows: When fuel is burned, water is heated to generate steam, which converts the chemical energy of the fuel into thermal energy. The steam pressure causes the steam turbine to rotate and the thermal energy is converted into mechanical energy. Then, the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy.
