What is a Diesel Power Plant? Diesel Power Plant is a electricity generation unit which intakes diesel as a fuel. They are basically big internal combustion engines which work on diesel cycle. They are used where supply of coal and water is low or where power requirement is very less. Essential components of Diesel Power… Read More »
In this article we will discuss fire tube and water tube boiler. Later in the article, we will also differentiate between them. Fire tube boiler In fire tube boilers hot gases are present in the tubes. These tubes are further surrounded by water. When heated this water converts into steam. They are considered as low-pressure… Read More »
What are Jigs and Fixtures? Jigs and fixtures are the devices which are used to increase productivity and accuracy in machining process. In general, we use the terms ‘Jig’ and ‘Fixture’ interchangeably for each other but, in reality they are both different terms and used for different applications. Let’s discuss the device Jig and the… Read More »
What is Liquid fuel? Liquid fuel is a combustible substance (in liquid form) which is used to obtain thermal energy (It is fumes of liquid fuel which are combustible).
