Circuit Breaker Operation Principle

It’s true that switchgear use to perform the most arduous duty when it is in operation. For better understanding we will learn the about the circuit breakers operation in switchgear operating principles. It will be easy to understand switchgear operation principle if we know circuit breaker operation principle. So let’s go. Circuit Breaker Operation Principle: Construction: Once I dismounted a 1000A MCCB. I found out the heart of a traditional circuit breaker is the contact system. Circuit breaker usually consist Read More …

Advantage and Disadvantage of Water Tube Boiler

Steam is an important source of energy for our modern age. We are using steam from very beginning of our first industrial revolution in human history. Now we are using steam from Textile Industry to Power Plant. In a Nuclear Power Plant steam use in a huge scale. For common usages we use very basic type of steam generator or boiler. Water Tube and Fire Tube Boiler is one of them. Both have some advantage and disadvantage. In this post we Read More …

Construction and Working Principle of Velox Boiler

Velox Boiler is a high pressure water tube boiler. Again if heat supplies through the tube and water supply around the tube then this boiler can be a fire tube boiler. Velox Boiler use GAS in Combustion Chamber. This Boiler has unique basic theory than others boiler that we already discuss about. When the GAS velocity exceeds the velocity of Sound, then heat transfer rate form the GAS much higher than rate achieve in subsonic flow. Velox Boiler used the Read More …

Construction and Working Principle of Loeffler Boiler

Loeffler Boiler is a high pressure, forced circulation and water tube boiler with internal furnace. In this boiler, 65 percent of super heated steam is used to evaporate the water. Everything happend in the Evaporating Drum. All done by the help of Mixing Nozzle. Remain 35 percent of super heated steam, uses by two Steam Turbines. Construction of Loeffler Boiler: Loeffler Boilers consist with a feed water pump and it circulates water to the Economizer. Generally hot flue gas passes through Read More …

Construction and Working Principle of Benson Boiler

In this post we will learn about the Construction and Working Principle of Benson Boiler. I also published couple of article about industrial boiler and if you want you can find it here after reading this article. Before we go farther lets know about person who invented this supercritical industrial type boiler. This boiler was invented by Mark Benson between 1926 to 1927.  But in 1924, Siemens acquired the right to use Benson’s patent. He was a Bohemian German engineer and best Read More …
