Trouble Shooting of vacuum in condenser

Check points for low vacuum in condenser   1.  Condenser and System Leak Checks ·         Inspect all flanges, joints, manholes, and sensor ports for air ingress. ·         Check for cracks on condenser body, vents , drains and pipe line. ·         Examine expansion bellows, rupture disks, and drain valves for leaks. ·         Use agarbati leak detection simple methods to find ingress points 2.  Ejector Inspection ·         Ensure vacuum ejectors are operating within design parameters. ·         Confirm proper operation of intake and exhaust valves. ·         Confirm ejector strainer and nozzles are properly cleaned 3.  Condenser Cooling and Water System ·     ...

What is heat rate?

Image
  In general heat rate is defined as ratio of heat input to power output in a system, in other way requirement of heat energy to generate one unit of power. In case of power plant cycle , output is electrical power and input is any kind of energy in fuel . If we consider steam turbine heat rate , input energy to turbine is in the form of steam energy i.e enthalpy corresponds to pressure and temperature. Different cases for steam turbine are considered as follows: Steam Turbine Heat Rate: CASE1: This is the calculation for closed cycle, single cylinder, condensing type of turbine where steam inlet to turbine at point no1 is expanded to point 2 as per below fig : Turbine Heat rate: M= Mass flow rate of steam inlet to turbine, kg/hr                                           ...
