1. To use the circulating water in the condenser of the steam turbine of a thermal power plant for heating, you must first select a specially designed steam turbine unit or carry out technical transformation of the steam turbine unit. existing steam and thermal system, because heating The circulating water supply requires a higher temperature. To increase the outlet temperature of the circulating water, the steam turbine must operate with increased back pressure. At this time, the load on the final stage blades of the steam turbine increases, and generally the final stage blades of the steam turbine need to be strengthened.
2. Open a tee on the circulating water pipe to connect it to the heating pipe. During the heating period, switch the circulating water from the steam turbine condenser to the heating water circulation system.
3. Ch stationsPeak heaters should be constructed to additionally heat the heating circulating water supply during peak heating periods to ensure heating quality.
4. Once the above conditions are met, the waste heat circulating from the power plant can be used for heating.
