Why tdbfp installed on turbine floor in thermal power plant?
TDBFP return drain is going to condenser hense TDBFP position should be above condenser elevation. If it's below turbone then return drain flow may be restricted. Sachin
How is cavitation avoided in tdbfp?
Cavitation in a thermodynamic boiling fluid pump (TDBFP) is avoided by maintaining adequate pressure at the pump inlet to ensure that the fluid does not vaporize. This is typically achieved through proper system design, including the use of suction diffusers and ensuring that the NPSH (Net Positive Suction Head) available exceeds the NPSH required by the pump. Additionally, operating the pump within its specified flow range and avoiding sudden changes in flow can help prevent conditions that lead to cavitation. Proper monitoring and control of temperature and pressure conditions further mitigate the risk of cavitation.
