Demonstration of Advanced Boiler Instrumentation Technologies

Demonstration of Advanced Boiler Instrumentation Technologies

Demonstration of Advanced Boiler Instrumentation Technologies Technical Report by EPRI includes New and increasing limits on emissions (in particular, NOx) and the new emphasis on heat rate have underscored the need to measure flue gas constituents more accurately and in more locations. Utilities are making large capital investments in boiler improvements and emission control devices. These investments can be enhanced …

Positive Displacement Pumps types and operation

Positive displacement pumps operate on a different principle than centrifugal pumps. Positive displacement pumps physically entrap a quantity of liquid at the suction of the pump and push that quantity out the discharge of the pump. A positive displacement pump is one in which a definite volume of liquid is delivered for each cycle of pump operation. This volume is …

Soot Blower in Boiler Fixed & Rotary Soot Blowers

Fixed position rotating soot blower Diamond company

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 depends upon the type of fuel being used. The flue …

Centrifugal Pump Operation

Centrifugal PUMPS BOOKS

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 the operator in avoiding pump damage. Many centrifugal pumps are …

Boiler Preservation Methods Dry and Wet

Boiler Preservation Methods

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 of boiler Boiler preservation through nitrogen method is also used …

Boiler Feed Water Pump Working Principle and Operation

Boiler feed water pump working principle and operation

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. To ensure a high enough head and pressure, Boiler feed …

Centrifugal Pump Components

Centrifugal Pump Components

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 within stationary pump casings. To allow the impeller to rotate …

Classification of Centrifugal Pump

Mixed Flow Centrifugal Pump

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 i.e. in terms of number of stages; • according to …

What are Centrifugal pumps?

centrifugal pump

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 fluids from one pressure to a higher pressure. Fluid enters …

Fluidized Bed Combustion FBC Boiler

Fluidized Bed Combustion FBC Boiler

“ (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 upward through the sand. With further increase in the velocity, …

Boiler Steam drum internals and function

Boiler steam Drum Internals

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 steam drum is determined by the volume required for a …
