STEAM ATTEMPERATION CONCEPT Superheating is a process in which stem is heated above saturation temperature & it is in the form of sensible amount of heat. For a unit he attemperation water, which is 2-5% of the total steam flow, may come from the boiler feed water pump outlet, orRead More

Tangential firing create turbulent zone in the center of the furnace by directing a horizontal coal firing from each corner of furnace. It form an imaginary circle in which the flame path is tangent. This is done at each elevation for tangential firing. As each elevation creates a circle thenRead More

“Overall, the mitigation through slow rotation aims to minimize thermal stresses, differential expansion, and associated mechanical problems in steam turbines during startup, shutdown, or other operational transitions..” 1. Introduction: 2. Consequences of Steam Admission Stopping: 3. Potential Issues with a Stationary Rotor: 4. Thermal Gradient within the Casing: 5. Thermal-InducedRead More

OBJECTIVE Auxiliary steam is the steam that is required for various auxiliary requirements in a power plant. A part of main steam is tapped off for auxiliary steam station from MS/CRH line, after pressure reducing and de-superheating up to 16 kg/cm2 & 320 °C. At the HT header (16 Kg/cm2 &Read More

Governing system is a device or combination of different system & logics which are used to control the speed of a steam turbine. A governor protects the prime mover from over speed & keeps the prime mover speed at or near the desired RPM. When a prime mover drives generatorRead More
