Features of MCCB and ACB with Advantage

You may already see or heard most two common names during your work and that is MCCM and ACB. This two switching device is used to control power in load incoming or outgoing side. But it always depends on the designer which type of switching device is appropriate to control a specific amount of load. These two devices have some basic feature and in this post, we will learn “Features of Moulded Case Circuit Breaker (MCCB) and Air Circuit Breaker Read More …

What Will Happen When You are Struck By Lightning?

Generally, lightning strikes are not always a death sentence. But we may get several news in each year that people died by the lightning around the world. Like this year in Asia several people killed by deadly lightning. Although 500 people who are struck by lightning each year and about them 90 percent survive. In this post, we will learn, “What Will Happen When You are Struck By Lightning?” Now before we go further let’s know about, How Lightning Actually Read More …

Low Voltage Switchgear Standards and Testing

Generally, all Switches, Switch Disconnectors, Disconnectors and Fuse combination units are designed to comply with the requirements, Standards, and Testing. All comply with the requirements of IEC 947-3 or EN 60947-3. This also requires a combination of type tests and routine tests before installation. For this reason, normally a sequence of type tests is required to prove that its compliance with the standard. In this post, we will learn about the Low Voltage Switchgear Standards and Testing with Sequence. Low Read More …

Circuit Breaker Operation Principle

It’s true that switchgear uses to perform the most arduous duty when it is in operation. For better understanding, we will learn about the circuit breakers operation in switchgear operating principles. It will be easy to understand switchgear operation principle if we know the 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 consists 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 the very beginning of our first industrial revolution in human history. Now we are using steam from the Textile Industry to Power Plant. In a Nuclear Power Plant steam use on a huge scale. For common usages, we use a very basic type of steam generator or boiler. Water Tube and Fire Tube Boiler are one of them. Both have some advantage and disadvantage. In 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 uses GAS in the Combustion Chamber. This Boiler has a unique basic theory than other boilers that we already discussed. When the GAS velocity exceeds the velocity of Sound, then the heat transfer rate form the GAS much higher than rate achieve in subsonic flow. Velox Boiler used Read More …

Construction and Working Principle of Loeffler Boiler

Loeffler Boiler is a high pressure, forced circulation and water tube boiler with the internal furnace. In this boiler, 65 percent of superheated steam is used to evaporate the water. Everything happens in the Evaporating Drum. All done by the help of Mixing Nozzle. Remain 35 percent of superheated steam, uses by two Steam Turbines. Construction of Loeffler Boiler: Loeffler Boilers consist of a feed water pump and it circulates water to the Economizer. Generally hot flue gas passes through the 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 a couple of article about the industrial boiler and if you want you can find it here after reading this article. Before we go farther let’s know about the 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 Read More …

Construction and Working Principle of Lamont Boiler

In this post, we will learn the Construction and Working Principle of Lamont Boiler. But who invented it? Ok, in the year of 1925, Lamont Boiler was invented by Walter Douglas La-Mont. Now let’s go and find out all about the Lamont Boiler. First, What is Lamont Boiler? Lamont Boiler is a water tube boiler which has an internally fired furnace, high pressure, forced water circulation system. As I say, forced water circulation system and for this reason, an external Read More …

Construction and Working Principle of Babcock and Wilcox Boiler

We already know that Boiler is an essential part of a thermal power plant. The boiler also uses in several industries like Dyeing Industry, Poultry Farm and others. This type of boiler called Industrial Boiler. What is a Water Tube Boiler? If a boiler having the system of water flow inside of its tube and heat flow system present in outside then it will be called a Water Tube Boiler. Water Tube Boiler can have Straight and Bent Tube, Cross, Read More …
