Study Notes
Power Plant Engineering Terminologies
- Power Plant Engineering Terminologies Reviewer: This document is a review of terms used in power plant engineering, specifically for Mechanical Engineering students at Sorsogon State College.
Electrical Circuit Components
-
Generator leads, feeder circuits, auxiliary power circuits, and field circuits: These components are essential in electrical circuits for generators and associated systems.
-
Ammeters, voltmeters, wattmeters: These instruments measure current, voltage, and power respectively, critical for circuit analysis and monitoring.
-
Ground detectors: Used for identifying ground faults and ensuring safety in electrical systems.
Fuel Measurement and Analysis
-
Calorimeter: Measures the heating value of fuel (energy content).
-
Hydrometer: Determines the specific gravity of a solution, often used to measure fuel density.
-
Pyrometer: Measures temperature, important in combustion analysis for fuel and other materials.
Boiler and Turbine Components
-
Gauge cock: Measures the water level in a boiler.
-
Steam trap: A device that allows water to pass but prevents steam from escaping, used to improve boiler efficiency.
-
Separator: Separates water from steam in a boiler system.
-
Fusible plug: A safety device that melts at a specific temperature, preventing overheating and damage in boilers.
-
Fire tube boilers and water tube boilers: Different designs for boilers; fire tube boilers have combustion gases passing through tubes surrounded by water, while water tube boilers have water surrounding the combustion gases.
-
Spark plug, carburetor: These components are associated with internal combustion engines, not necessarily boilers.
-
Steam turbine: The turbine converts steam energy into mechanical energy, often driving a generator in a power plant.
-
Rotor, turbine blades, or buckets: Critical parts of the turbine to transform steam energy output.
Thermodynamics Concepts
-
Heating value of fuel: Heat released during fuel combustion.
-
Heat transfer: Transfer of thermal energy from one substance to another.
-
Saturation temperature: The temperature at which a substance changes from liquid to gas at a given pressure.
Engine Types
-
Spark-ignition engine: An internal combustion engine that ignites fuel through an electric spark.
-
Compression-ignition engine: An internal combustion engine that uses compression to heat the fuel and initiate combustion.
-
Internal combustion engine: Engines where combustion occurs directly within the engine cylinder.
-
External Combustion Engine: Engines where combustion happens outside of the cylinder, and the result is used for heating an internal working substance.
Measurement and Quality Control
-
Specific gravity: Measurement of density relative to water; important for fuel analysis.
-
Calorimeter: Instrument used to measure the heat generated during a process.
Power Plant Components and Characteristics
-
Boiler meter: Instrument that measures the performance of a boiler, potentially used for monitoring major boiler items.
-
Cylinders and other Engine parts: Parts that work in combination making up a component of an engine.
-
Exhaust gases: Gases produced during combustion.
Engine Cycles
- Otto cycle, Diesel cycle: Different thermodynamic cycles used to describe the operation of internal combustion engines.
Miscellaneous
-
Ideal gas/pure substance: Characteristic elements that help describe a material in a given situation.
-
Boiling point: The temperature at which a liquid boils and changes to a gas.
-
Properties of matter: Properties that help describe a material in a given situation.
-
Specific heat: Heat required to raise the temperature of a unit mass of a substance by one degree
-
Indicator: Instrument for analyzing a characteristic.
-
Compression-ignition engine: An internal combustion engine that uses compression to heat the fuel and initiate combustion.
-
Fuel analysis: Analyzing the composition, properties, and quality of fuels.
-
Engine parts: Different components that make up an engine.
-
Engine testing: Methods, instruments, and tests that assess engine performance.
Additional Terms
-
Boiling point: The temperature at which a liquid changes to a gas at a given pressure.
-
Critical point: The critical temperature and pressure at which the liquid and gas phases become indistinguishable.
-
Pour point: The temperature below which an oil becomes too viscous to flow.
-
Flash point: The lowest temperature at which a liquid gives off enough vapor to form an ignitable mixture with air.
-
Combustion: The chemical process of burning fuel, releasing energy.
-
Fuel types and characteristics: Different types of fuels (e.g., diesel fuel, gasoline) and their properties.
-
Power plant types: Various types of power plants (e.g., steam, gas turbine, nuclear).
-
Performance parameters: Measures of power plant operation (e.g., efficiency, capacity factor).
