Basic function of Boiler feed water pump is to produce sufficient amount of pressure required to turbine inlet with added amount of pressure drop of flow path of boiler components.Pressure required to develop through bfp = Turbine inlet pressure + Pressure drop of boiler componentsand also its a prime important in case of develop more than saturation pressure in case of supercritical boiler segments concernBoiler feed pump is used to feed water to steam generator boiler drum at desired pressure and temperature.Need of boiler feed pump?As the water is fed to the steam generator it has to be at the temperature & Pressure that of the steam generator.Boiler feed pumpProcess of water flow?Boiler feed pump extract water from de-aerator and feed it to the boiler drum via H.P heaters and economizer.General configuration of Boiler feed pump?Generally 2 Turbine driven boiler feed pumps (1 Working & 1 Standby) & 1 Motor driven boiler feed pump is used for 1 unit.Turbine driven boiler feed pump: It works with the steam extraction from Intermediate Pressure (I.P.) turbine exhaust.Motor driven boiler feed pump: It works with a motor as the name specifies.Swas roomSteam Water Analyzer System Room, it is used to analyze boiler steam and water.The following parameter are therei) Spec Conductivity (insertion type)on both side5.08.03 Cond.

Moreover, the quality of the equipments and the lower mechanical stress on the installed machinery guarantee it a longer life time and a substantial cut on its maintenance costs. The present document aims to examine the energy benefits of a viable technology change on the existing motorized systems at Lanco. Changes may include replacements of motors with low efficiency and / or system upgrade through the retrofit of variable speed drives to the existing motors. The energy consumption analysis also leads to an economical estimation of the savings and a balance to the possible investment.What is VFD?A variable frequency drive (VFD) is an electrical variable speed drive that is added to motor-driven systems to help save energy. Motor-driven systems are designed to handle peak loads. When these operating systems work for extended periods of time at a reduced load, it wastes energy. Adding a VFD allows you to adjust the motor-speed capability and match it with motor-output load. This is how it saves energy. The motor-driven system is connected to the VFD and allows us to have speed control by changing the frequency of the motor-supply voltage.How VFD functions?A motor-driven system is controlled by the frequency of the supply voltage and rotates on a fixed speed. An alternating current that is applied produces a magnetic field that rotates at synchronous speed. The only way to alternate synchronous speed is through a VFD, which converts the power in three stages. In the rectifier stage, the power is converted to a higher adjustable DC voltage. In the inverter stage, the power transistors in the rectified DC are switched off and on. This produces a voltage waveform at the frequency you want. In the control system, the voltage wave form receives information from the motor-driven system and will adjust the output voltage to the selected value.CURRICULUM VITAE :ASHISH SHARMAE-mail :- ashishsharma1100 AT gmail.com , ashishsharma.ritee AT yahoo.com CAREER OBJECTIVE : -Intend to a build a career a with leading corporate of hi-tech and environment with committed & dedicated people which will help me to explore myself fully & realizemy potential, willing to work as a key player challenging & creative environment.CAREER PATH : -WORKING EXPERIENCE: - Total 2 Years 1 Month experience in power plant operation and maintenance.
