In almost any power, chemical, or mechanical system, heat must be transferred from one place to another or from one fluid to another. Heat exchangers are used to transfer heat from one fluid to another. A basic understanding of the mechanical components of a heat exchanger is important to understand how they function and operate. Introduction to Heat Exchangers A …

Today we will discus about the role of Chemistry in a Power Plant Boiler and why it is important to maintain chemistry in the power plants. As we know much of the equipment is made of metals that are expected to have a long life in power stations with little or no failure. Experience has taught us that metals are subject …

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 …

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 …

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 …

“ (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, …

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 …

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 require boiler inspection to be done at least every year. …

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 these applications is different, so how to design a boiler …

Boiler Water Treatment is necessary to Produce quality steam on demand and depends on properly managed water treatment to control steam purity, deposits, and corrosion. There are two main types of boiler feed water treatment Internal boiler Water Treatment method and external boiler water treatment. A boiler is the sump of the boiler system. It ultimately receives all of the …

Stoker Fired Boiler are classified according to the method of feeding fuel to the furnace and by the type of grate. The main types of stokers are: Chain-grate or travelling-grate stoker Spreader stoker boiler Travelling Grate or chain grate Stoker Boiler In Travelling Grate  boiler coal is fed at one end of a moving steel chain grate. As grate moves …

A vertical boiler is a type of steam boiler that is designed with a vertical cylinder shape. Vertical boilers are often used in small- to medium-sized facilities, such as schools, hospitals, and small industrial plants, where space is at a premium. This is the simplest type of fire tube boiler. A simple vertical boiler produces low Pressure and a small …
