Sound and Exposure Standards
How many crickets clicking their legs together in unison would it take before we would suffer hearing loss at the sound exposure? Would we need to sit in a garden…
Sound and Its Control
How do they do it? Your teenager is busily doing his homework, the sound on their stereo speakers cranked up way past the point of your comfort. As the heavy…
Transformers – Electric Utility Power Savers
Each day millions of Americans start their mornings with coffee, brewed in a coffee maker, and a microwaved breakfast. They flick on the light and exhaust fan before starting their…
Coal Power Plant Fundamentals – The Generator
When I was a kid I remember how cool it was to have a headlight on my bike. Unlike the headlights that the other kids had, mine was not powered…
Industrial Control Basics – Manual Control
You’ve probably heard the saying, “asleep at the switch.” It’s usually associated with some sort of disaster, found later to have been caused by human error. Someone wasn’t paying attention,…
Heat Energy Within the Power Plant— Water and Steam Cycle
This clarified water is then fed to a boiler by the boiler feed pump as shown below. As it stands this setup will work to provide electricity,…
Superheating
power plant boiler as presently designed doesn’t do a good job of producing ample amounts of superheated steam, the kind of steam that turbines need to spin and power generators. During the…
Condensation Inside the Steam Turbine
Did you know that water droplets traveling at high velocity can take on the force of bullets? It can happen, particularly within steam turbines at a power plant during the…
The Make-up Valve in the Power Plant Steam to Water Cycle
This water is known as condensate, and after leaving the boiler feed pump at high pressure, it’s known as boiler feed water. Today we’ll introduce a special valve into the system, whose…
Vacuum in a Power Plant Condenser
As discussed previously, the condenser is a piece of equipment that turns turbine exhaust steam back into water. The water that’s formed during this process is known as condensate, and…
