Large Boilers in power plants are fitted with soot blowers, which are tools to keep the outside surface of the tubes clean and free from material or ash that would have a detrimental effect on the heat transfer surface. The blowing fluid is generally steam and the frequency of operation …

Improper operation of centrifugal pumps can result in damage to the pump and loss of function of the system that the pump is installed in. It is helpful to know what conditions can lead to pump damage to allow better understanding of pump operating procedures and how the procedures aid …

Boiler preservation is required when boiler is out of service or in shutdown condition for a long period to protect boilers internal surface from corrosion and atmospheric oxygen. There are two types of boiler preservation methods each of them is used in specific conditions. Wet preservation of boiler Dry preservation …

Today we will discuss about (BFWP) boiler feed water pump working principle and operation of a boiler feed water pump. The boiler feed pump function is to supply pressurized feed water to the boilers to maintain the water inventory at various operating loads. Boiler feed water pumps are commonly centrifugal pumps. …

Centrifugal pump Components vary in design and construction from simple pumps with relatively few parts to extremely complicated pumps with hundreds of individual parts. Some of the most common components found in centrifugal pumps are wearing rings, stuffing boxes, packing, and lantern rings. Wearing Rings Centrifugal pumps contain rotating impellers …

Classification of Centrifugal Pump Centrifugal pumps are classified in several ways. Pumps may be classified: • in terms of energy conversions (volute type and diffuser vane ring type); • in terms of fluid flow through the pump (radial, mixed flow and axial flow); • as either single stage or multistage …

Introduction to Centrifugal pumps Centrifugal pumps are the most common type of pumps found in industrial applications. Centrifugal pumps enjoy widespread application partly due to their ability to operate over a wide range of flow rates and pump heads. The centrifugal pump, as the name implies, uses centrifugal force to transfer …

“ (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers.” In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass …

In the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes. The size of the …

Pressure vessels and Boiler Inspection are done to determine the amount of maintenance required to have equipment operate properly until the next turnaround. A comprehensive equipment history must be maintained that includes conditions found during inspection and testing, maintenance work done, changes made, and date of each. ASME Code Standards …

Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water for steam generation. Steam produced can be used for a variety of purposes including space heating, sterilization, drying, humidification, and power generation. The temperature or condition of steam required for …

Many hazards are associated with welding and cutting safety, but as in any other operations they can be controlled by appropriate preventive measures. Unless these measures are taken, the hazardous situations can easily give rise to personnel injury and/or material damage. Welding and cutting hazard examples are:- Electric shock Fumes …
