Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 6.2.5 System Description: FW System Turbine Driven (TD) BFP. In larger units, to reduce auxiliary power consumption and better steam utilization, a steam turbine is used to drive BFP in place of a motor. Extraction steam is the main source of steam supply to this BFPT.
