Stress concentration is the accumulation of stress in a body due to sudden change in its geometry. When there is a sudden change in the geometry of the body due to cracks, sharp corners, holes and decrease in the cross section area, then there is an increase in the localised stress near these cracks, sharp […]

In this article, we will discuss about the difference between SI engine and CI engine. The Spark Ignition (SI) engine, as its name indicates uses spark to ignite the fuel. In a Compression Ignition (CI) engine, the air is compressed within the cylinder and the heat of this compression air is used to ignite the
Since there are many types of springs but here I will discuss their types only on the basis of their shapes and how the load force is applied on them. The springs are defined as an elastic body which stores mechanical energy and gets distorted when loaded and regains its original shape when load is
In this article, we will learn about the difference between turbocharger and supercharger. They both are forced induction system i.e. they compress the air from the atmosphere and sends it to the engine cylinder. The compressed air allows a double amount of fuel to enter into the cylinder for combustion. This doubles the power of

In this article, you will learn about the lever safety valve – definition, main parts and working. It is used for the boiler. The main purpose of this safety valve is to prevent the explosion of the boiler due to the increased steam pressure. This device helps to prevent a major accidents in steam power

In the United States, high-pressure boilers are a critical part of thermal power plants, industrial steam systems, and engineering education. As power plant operating pressures increased during the mid-20th century, engineers faced serious challenges such as salt deposition, tube scaling, and reduced heat-transfer efficiency. To address these issues, advanced boiler designs were developed—one of the most innovative among them

In mechanical engineering, boilers play a vital role in converting thermal energy into usable mechanical power, and among the classical designs, the locomotive boiler holds a special historical and academic importance. Widely used in railway steam engines and early marine applications, the locomotive boiler is known for its compact construction, mobility, and high steam generation

The Lamont boiler is a high-pressure, forced-circulation water-tube boiler designed to generate large quantities of steam efficiently within a compact space. Unlike natural circulation boilers that rely on density differences, this boiler uses an external pump to circulate water at high velocity through small-diameter tubes. This design significantly improves heat transfer and allows the boiler to operate

Boilers play a very important role in thermal power plants because they convert water into high-pressure steam, which is then used to rotate turbines and generate electricity. Over time, boiler technology has evolved from basic fire-tube boilers to highly efficient, supercritical boilers. Traditional boilers often had limitations such as: These limitations reduced efficiency and increased

Steam Condenser is a mechanical device that converts the low-pressure exhaust steam from the turbine into water. Or in other words, it is a device that is used to condense exhaust steam of the turbine into water. It does so with the help of cooling water circulated into it from the cooling tower. It works
