There is a disproportionate relationship between auxiliary engine cooling water temperature and coal consumption economy. So-called auxiliary machines are unimportant auxiliary machines. As long as the cooling water does not exceed the temperature, it will not affect production. Even if the water temperature is high, it will be treated in time. Therefore, the cooling water temperature of auxiliary engines is related to the reduction of coal consumption, but the impact is so slight that it cannot be calculated. The main economic indicators that have a significant impact on coal consumption are: circulating water temperature, condenser vacuum, exhaust gas temperature, oxygen content, power consumption rate of the plant, carbon content of fly ash, steam temperature and steam pressure deviation, etc.
The grouppe condenser type steam turbine generator is equipped with a condenser. The main function of circulating water is to cool the steam generated by the turbine through the condenser and cool the steam into condensed water for recycling. . Circulating water also plays a role in cooling the lubricating oil. In addition, domestic firefighting water, industrial water and desalinated water from the power plant are all treated from the circulating water system.
