Principle Of Industrial Catalyst And Classification Of Catalyst. Principle Of Industrial Catalyst : An industrial catalyst is a substance that accelerates a chemical reaction without undergoing any significant change in its own chemical composition. Catalysts work by lowering the activation energy required for the reaction to occur, thereby increasing the reaction rate. They provide an alternative pathway for the reaction to take place, which requires less energy and allows the reaction to proceed at milder conditions such as lower temperatures and pressures. Industrial catalysts are used in a wide range of chemical processes, including petrochemicals, refining, polymerization, and environmental applications. Classification Of Industrial Catalyst : Industrial catalysts can be classified into four main groups: 01. Homogeneous catalysts. Homogeneous catalysts are soluble in the reaction medium and are used mainly in the production of fine chemicals and pharmaceuticals. 02. Heteroge...
Steam turbine consists of 4 basic parts:- 1️⃣ Rotor, which carries the blades or buckets 2️⃣ Stator, consisting of cylinder and casing, which are often combined and within which the rotor turns 3️⃣ Nozzles or flow passages for the steam, which are generally fixed to the inside of the cylinder 4️⃣ Frame or base for supporting the stator and rotor There’re 4 Directions of the Steam inside ST:- 1️⃣ Axial Flow 🗜 It signifies steam flow substantially parallel to the axis of rotation, among blades that are set radially. This is the only arrangement used in medium and large turbines and is most commonly used also in small turbines. 2️⃣ Radial Flow ⌛ ️It’s obtained when the steam enters at or near the shaft and flows substantially radially outward among blades, which are placed parallel to the axis of rotation. 3️⃣ Tangential (Helical) Flow 🔋Tangential flow is the term applied when the steam enters through a nozzle placed approximately tangent to the ...
