Shaft seal heater and Collaborative operation of steam turbine,The key to improving economy.

Recycling shaft seal leakage:During the operation of the steam turbine, if steam leaks from the shaft seal, the shaft seal heater cools the steam gas mixture, causing the steam to condense into water and recover the working fluid.

Utilize the heat from steam leakage:The shaft seal heater uses the heat from steam leakage to heat the condensed water, increasing the temperature of the feedwater entering the boiler and improving the thermal economy of the unit.

Maintain micro vacuum in the shaft seal system:The shaft seal heater is matched with the shaft seal fan to maintain a slight vacuum on the steam side, guide the leaked steam into the heater, and prevent steam leakage.

Protecting turbine components:Control the temperature and pressure of the shaft seal steam supply to prevent damage to the turbine body components due to thermal stress and ensure safe operation of the unit.

Adapt to the operating conditions of the unit:Under different operating conditions, adjust parameters in conjunction with the shaft seal steam supply system to meet the sealing requirements of each shaft seal of the steam turbine and ensure stable operation.
