The document provides information about a turbine driven boiler feed pump (TDBFP) system, including: 1) Key specifications of the TDBFP such as its rated power output, operating speed range, steam pressure and temperature, number of pump stages, and maximum flow rate.

This document provides the standard operating procedure for operating the Turbine Driven Boiler Feed Pump (TDBFP) located at the Singareni Thermal Power Plant's 2x600 MW power plant. It outlines the pre-start checks, oil charging procedure, start-up procedure, and stopping/isolation procedure for the TDBFP in step-by-step detail.

2015年8月5日 · For TDBFP pumps are same whether it is booster pump or main pump. Instead of MOTOR driven we have variable speed turbine with disconnecting coupling both sides . In this blog we will discuss only the turbine as pumps are similar.

In this case, a major ( 3*660 MW ) Thermal Plant encountered frequent performance and mechanical integrity issues in the turbine-driven Boiler Feed Pump (TDBFP). The TDBFP faced several challenges affecting its performance and reliability, posing …

This document provides information on the components and operation of a turbo-driven boiler feed pump. It describes the turbine casing, shaft packing, oil guards, diaphragms, main bearings, thrust bearing, rotor, turning gear, axial position device, rotor vibration device, differential expansion device, case expansion device, speed indicator ...

2017年10月28日 · TDBFP Ready for Rolling. Open BFP Discharge valve at 60 ksc of Discharge Pressure; Record all TSI and other parameters before and after Rolling; FW side vent valves are to be tightly closed before attaining full pressure; Keep steam vent upstream of ESV OPen while Opening CRH Block valve; Open CRH Bock valve before loading the TDBFP; Open ...

Generally in 500 MW above plant size, Turbine (steam operated) Driven BFP (TDBFP) are used because the motor size will be very big of the order of about two numbers of 10 MW size. Starting...

The failure occurred in a turbine-driven boiler feedwater pump (TDBFP) at a fossil fuel power plant. Specifically, the outboard boiler feed pump unexpectedly shut down while the plant was operating under normal conditions, leading to a forced outage. Here is a basic process flow diagram for this process:

2016年1月19日 · Keep the turbine along with main pump and booster pump on hydraulic barring. Raise the speed of the TDBFP to rated speed as per start up curve. Keep the pump on recirculation flow of approximately 250 T/hr for 8 hours to observe and record performance.

This document provides a commissioning procedure for a turbine driven boiler feed pump at the Jindal Power Limited O.P.J.S.T.P.P. power plant in Tamnar, Raigarh, India. The procedure outlines the plant details, objectives, proposal, safety precautions, state of the plant, and methods to commission the boiler feed pump system over multiple steps ...
