A boiler is a combination of systems and equipment in which chemical energy is converted into thermal energy, which is then transferred to working fluid, so as to convert it into steam at high temperature and pressure.
Corrosion is a relevant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen, to corrosion currents set up as a result of heterogeneities on metal surfaces, or to the iron being directly attacked by the water.
While basic corrosion in boilers may be primarily due to reaction of the metal with oxygen, other factors such as stresses, acid conditions, and specific chemical corrodents may have an important influence and produce different forms of attack.
The document provides details about a main project report submitted by four students for their Bachelor of Technology degree. It discusses studying various systems in a 500MW thermal power plant. The report includes chapters on the coal handling plant, ash handling plant, electrostatic precipitator, boiler, steam turbine, generator, condenser and cooling towers, water treatment plant, transformers, switchyard, and the start up procedure for Dr. NTTPS Stage-4 plant. The objective of the project is to study the operation, maintenance and protection of power transformers used in Stage-IV of Dr. NTTPS thermal power plant.

Heat rate is the pulse rate of a power plant to know the health of the plant.
Net heat rate is the single parameter that encompasses total performance indices of a power plant.
The document discusses the hydrogen seal oil system on a generator. It describes the purpose of the system as preventing hydrogen gas from escaping along the generator shaft by forming an oil film between the shaft and seal ring. It outlines the normal flow path of oil through the main seal oil pump and other components like the vacuum tank, emergency seal oil pump, and detraining tanks. It also discusses potential failures of components like pumps and the float trap, and the appropriate operator actions to take in response.
This document discusses the control and instrumentation system for the Jaypee Bina Thermal Power Plant's 2x250 MW furnace safeguard and supervisory system (FSSS). The FSSS is designed to safely start up and shut down the boiler and prevent operator errors. It monitors the burner block assembly and controls the furnace purge sequence, oil gun operation in pair or elevation mode, and high energy arc igniter system to safely initiate combustion. The FSSS ensures maximum safety and efficiency during plant operation.
This document provides information on chemical cleaning of industrial boilers. It discusses the chemistry of boiler scale and compounds that can form scale such as magnetite, calcium sulfate, and copper. It outlines the steps to determine if a boiler needs chemical cleaning based on scale density. The document then details the various chemical cleaning processes including alkaline treatments using soda ash, caustic, or permanganate depending on organic contamination levels. It also discusses solvent/acid cleaning options and control parameters for using hydrochloric acid, citric acid, EDTA, sulfuric acid, or sulfamic acid. The goal of chemical cleaning is to remove scale without damaging boiler materials.
Raw Water Intake & Pre Treatment of Raw Water in a Thermal Power PlantSUDHEER KUMAR KALYANAM
The document discusses the treatment process for raw water from rivers and lakes. It describes how raw water contains physical, biological, and chemical impurities. The treatment process involves intake, screening, pre-chlorination, storage, aeration, coagulation, flocculation, clarification, filtration through sand and activated carbon, and storage of filtered water. This multi-stage process removes suspended solids, bacteria, algae and other contaminants to produce portable water suitable for drinking and industrial use.
1) The document describes the governing system and components of a steam turbine. It includes throttle controlled governing and discusses advantages like avoiding overspeeding and adjusting droop.
2) It lists the different oils used like trip oil, auxiliary trip oil, and control oil and describes what each oil is used for like tripping the stop valve or hydraulic governing.
3) The main elements of the governing system are described including remote trip solenoids, main trip valve, speeder gear, and follow-up piston valves that control steam flow and turbine speed.
