We will discuss important steps involved in Boiler gas tightness test procedure. -Close all the dampers in the grate hopper of the boiler. -Run the FD fan and open all the dampers excluding the dampers in the grate hopper. Keep air pressure and running time as approved by design. Detect leakage by soap solution /smoke test. Vital points for leakage …

Boiler Refractory dry out is to ensure proper drying, curing of refractory applied on furnace and other components. The refractory usually undergoes considerable chemical changes, during initial heating. Controlled heating, through these reactions ensures maximum strength. While heating, there must be free air flow over the system to ensure removal of moisture. In order to commence refractory dry out, the …

The operation of checking the equipment and tuning them before putting into commercial operation is commonly termed as ‘commissioning’. The boiler commissioning activity includes the following: Boiler Inspection, pre-operation checking and preparation of the equipment including specialized cleaning. Trial run, initial operation and performance monitoring. Many of the equipment including auxiliaries, such as fans, ESP, handling system, etc., are engineered …

This procedure defines the requirement and procedure of hydrostatic testing of the boiler pressure parts after completing the assembly of all the boiler high pressure and temperature components. Hydrostatic testing Objective Hydrostatic testing in the boiler is carried out to check the following: Leakages in the boiler pressure parts (Tubes, headers and Pipes). To test the soundness of welded joints …

Boiler engineers can increase boiler efficiency up to 10% without even spending any penny or up to 15% with spending some money. Take these steps on your steam boiler and you can save a lot of energy, fuel, and money.  25 ways to increase boiler efficiency Control excess air in your boiler. A 5% Reduction in the Excess air can …

Pressure Safety valve or PSV Valve is the most important valve on a boiler used to relief excess pressure to atmosphere let’s see how psv valve is important, Let’s discuss about Pressure safety valve theory installation rules and PSV valve mechanism, Sv setting, testing and the types. Purpose and safety PSV Valve The maximum allowable working pressure (MAWP) for the …

What is Deaeration? The process through which the dissolved corrosive gases are removed from the Boiler Feed water is called deaeration. The equipment, which is used in this method, is called Deaerator. Today we will discuss Boiler Deaerator Working Principle. The necessity of deaeration: Deaeration is needed to control the corrosion processes in the downstream system. In water, the presence …

The basic principles on which a boiler operates remains the same. Boilers also have different models, today we will talk about “fire tube boiler”. What is a Fire tube boiler? The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by …

What is a water tube boiler? Water tube boilers were developed for a variety of reasons, including the need for higher steam pressures, higher steam generation rate, superheated steam. these types of boilers have quicker response to load changes. We briefly discuss about Water tube boiler parts and functions. In the water tube boiler, the water and steam flow inside …

What is a scaffold? Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Scaffolds should provide use with safe platform to work from.  Unsafe scaffolding has the potential to result in death or serious injury to those working from the scaffold or around areas where scaffolding is being …

What is a pressuretrol? The pressuretrol is an important boiler control mounting as how pressuretrol works? is the today question asked by someone in group, simple answer is that the pressuretrol in a boiler works as pressure control switch that turns the boiler on and off at adjusted pressure. The pressuretrol is an important safety device in a steam boiler …

Introduction of Nuclear Power Plant In a nuclear power plant, nuclear fuel is used such as Uranium U235. The difference between a thermal power plant and nuclear power plant is fuel. Both use their fuel to convert water into steam in Boilers (Steam generators). This steam is used to run the steam turbine to produce electricity. The thermal power plant …
