Deaerator

Sep 15, 2020Deaerator solves the purpose of removal of unwanted dissolved gases and dissolved oxygen from the boiler feed water before entering into boilers. Most of the deaerators are designed in such a way that the dissolved oxygen content in the outlet water is about 7 ppb by wt% Principle of Dearators. Dearator normally works based on the following

Boiler Mountings And Their Function

Aug 05, 2018Boiler mountings are a set of safety device installed for the safe operation of a boiler. There are seven main mountings on a boiler shell; safety valve, steam stop valve, vent valve, pressure gauge, water level indicator, feed check valve and fusible plug. These equipment save the boiler from damage due to extreme pressure, steam back flow

Boiler Mountings

Principle: The principle of operation of a safety valve depends on the fact that a valve is pressed against a seat through some external force. When the steam force corresponding to boiler pressure acting under the valve exceeds the external force, the valve gets lifted off its seat allowing some of the steam to escape until the working

Boiler corrosion 3. Boiler troubles: Sludge, scale, priming and foaming, caustic embrittlement, boiler corrosion are collectively known as boiler troubles. A. Caustic Embrittlement: (Inter crystalline cracking of boiler metal) It is the intercrystalline cracking of boiler due to Na2CO3. In high pressure, Na2CO3 undergoes hydrolysis to produce NaOH.

Your guide to safer boiler operation

Boiler water-level– The first duty when taking over a boiler-room shift is to make certain the pipe, fittings and valves . between the water glass and boiler are free and open by blowing down the water column and water glass and noting the promptness of the return of water to the glass. The most important rule

Centrifugal Pump Working Principle

The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes. The basic centrifugal pump theory of working comprises of the following working stages. - Liquid enters the pump casing at the impeller eye.

Types of Level Measurement Transmitters How Do They Work?

Apr 20, 2018The working principle of level transmitters mentioned above varies according to their underlying principle. For instance, capacitance level transmitters operate through a capacitor, hydrostatic level transmitters depend on the pressure of a fluid in a storage container for level measurement, while ultrasonic level transmitters convert the

Types of Boilers: Based on Principle of Working: 1. Fire tube boilers 2. Water tube boilers 1. Fire tube boilers : Fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal

Marine Engineering

Marine Engineering The maritime industry is a rapidly changing one and marine engineering is an integral part of it. Marine engineers working in the industry have to keep themselves abreast with the latest developments and regulations. Needless to say, in a field like marine engineering, the process of updating oneself is a continuous one and there []

Thermal Power Plant Working

Generally in modern boilers tangential firing system is used i.e. the coal nozzles/ guns form tangent to a circle. The temperature in fire ball is of the order of 1300 deg.C. The boiler is a water tube boiler hanging from the top. Water is converted to steam in the boiler and steam is separated from water in the boiler Drum.

work. Now, it is generally during the night that the heating period is triggered (case of electric meters with off-peak time rates). Thus the heating of the water adds to the increase of water mains pressure, and causes the pressure in the tank to reach the safety valve set-point, producing a water outflow higher than water expansion.
