There are different components present in feed water and steam circuit of boiler and we should know some essential components of these circuit and these are Economizer, boiler drums, water tubes, and super heater.Economizer Economizeris a heat exchanger which takes heat from the flue gas, and increases the temperature of feed water coming fromfeed watercommon header to about the saturation temperature corresponding to theboilerpressure. Throwing away the flue gases of high temperature into the a

All natural sources of water contain impurities as well as dissolved gasses. The amount of these impurities depends on type of water source and location.Why it is necessary to treat the raw water?Raw water coming from different sources contains dissolved salts and un-dissolved or suspended impurities. It is necessary to remove harmful salts dissolved into the water before feeding it to the boiler.Because- The deposition of dissolved salts and suspended impurities will form a scale on the inside

A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.Advantages of Water Tube BoilerThere are many advantages of water tube boiler due to which these types of boiler are essentially used in large thermal power station. Larger heating surface can be achieve

What is a Steam Boiler?A boiler (also known as a steam boiler) is a closed vessel in which fluid (typically water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, such as cooking, water or central heating, or boiler-based power generation. Boilers (or more specifically steam boilers) are an essential part of thermal power plants.Working Principle of BoilerThe basic working principle of boiler is

What Does an Economizer Do in a BoilerA boiler economizer (also known as an economizer) are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. A boiler economizer is essentially a heat exchanger that makes a system more energy efficient by taking enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler – hence recovering more useful enthalpy and improving the steam boiler’s efficiency.After producing steam, f

Stirling Boiler is one of the most basic variety of bent tube boiler. In most of the modern thermal power generating plants we use bent tube boiler. Stirling Boiler is one of the largest capacity boiler. A Stirling Boiler can generate as high as 50,000 kg steam per hour and can produce pressure as high as 60 kgf per cm2. This boiler was first designed in the year of 1888 by Alan Stirling so we refer the boiler as Stirling Boiler. Because of the huge capacity we can use this boiler in central pow

A fire tube boiler is a type of boiler that uses hot gases from a fire to heat water inside a series of tubes. The tubes are surrounded by water in a sealed container. The heat from the gases transfers through the walls of the tubes by thermal conduction, creating steam that can be used for various purposes.Fire tube boilers are one of the oldest and most basic types of boilers. They were widely used in the 18th and 19th centuries, especially for steam locomotives and other steam engines. Today,

Introduction of Fire Detection and Alarm SystemFire detectors are designed to detect one or more of the three characteristics of fire-smoke, heat and flame. Besides it every fire detection system must include manual call points (break glass), so that in the event of fire can be of immediate help.During a fire importance of activation of the occupants through alarm or bell is of at most vital and this can performed through alarm system.Fire alarm system shall be designed to provide round the cloc

Foam Fire Protection System is fire suppression system. Its success is mainly depends on proper mixing of foam concentrate along with air and water, to form a uniform foam blanket to extinguish flame.Back Ground of Foam Fire Protection SystemWater is known for suppressing fires, but unfortunately not best in all the cases. Water is not effective on an oil fire, and can be of no use during emergency. To suppress oil fire foam is reliable to use, since it prevent the direct contact of fire with ox

An MVWS system (short for a Medium Velocity Water Spray System) is a water-based fire protection system. MVWS systems are used to provide cooling and/or control the burning in many large scale industrial applications, such as in thermal power plants.As their name suggests, medium velocity water spray nozzles are designed to spray water at a medium velocity (i.e. the strength of the spray is weaker than HVWS systems). MVWS systems are best suited for protecting hazards involving light oils – wher
