The packaged boiler is so called because it comes as a complete factory-assembled Package with all mountings,  accessories and control instrumentation are installed on it. Once it delivered to site, boiler requires only the steam, feed water pipe line. fuel supply connections and electrical connections to be made for package boiler to become operational and produce steam. Package boilers are …

Electrostatic precipitator meaning an efficient flue gas cleaning device  ESP means Electrostatic precipitator is a device have been used for over half a century to control particulate emissions or dust cleaning device in many industries like power plants boiler ,cement and steel mills. Electrostatic precipitators have a very high collection efficiency upto 99%. ESP can handle large exhaust gas volumes …

This Steam Blowing procedure is intended to provide general application guidance and establish controls during Steam Blowing of piping and equipment. The purpose of steam blowing, prior to start-up of a new unit, is to remove any foreign material in the superheater and steam piping after the erection completion. Considerable damage could result, if such foreign material is allowed to …

Boiler Alkali boil out is carried out to remove material such as lubricants, oil, and rust. During the manufacturing of seamless steel tubes, mill scales are bound to be formed, and some of these can remain inside. During fabrication and erection of the pressure parts, some amount of oil and lubricants can also. get into the tube surface apart from …

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 …

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 …
