Wet scrubber is a device used to remove pollutants from industrial exhaust gases.
It uses water or other liquids to capture and remove pollutants from the gas stream.
The liquid absorbs the pollutants and is then removed from the system.
Wet scrubbers are commonly used in industries such as chemical, pharmaceutical, and power generation.
Examples of pollutants removed by wet scrubbers include sulfur dioxide, nitrogen ...
Low pressure boilers operate at a pressure of up to 15 psi while high pressure boilers operate at a pressure greater than 15 psi.
Low pressure boilers are used for heating and producing hot water while high pressure boilers are used for power generation and industrial processes.
Low pressure boilers have a simpler design and are less expensive to operate and maintain than high pressure boilers.
High pressure boilers ...
The process of starting a boiler involves several steps to ensure safe and efficient operation.
Perform a visual inspection of the boiler and surrounding area
Check the water level and pressure
Open the fuel valve and ignite the burner
Monitor the temperature and pressure
Adjust the fuel and air flow as needed

Blowdown in a boiler is the process of removing impurities and sediment from the boiler water to maintain its efficiency and prevent corrosion.
Blowdown is necessary to control the concentration of dissolved solids in the boiler water.
It involves draining a portion of the boiler water and replacing it with fresh water.
Blowdown helps to remove sludge, scale, and other impurities that can accumulate in the boiler.

Boiler efficiency is a measure of how effectively a boiler converts fuel into usable heat energy.
Boiler efficiency is expressed as a percentage.
It is calculated by dividing the energy output of the boiler by the energy input.
Factors affecting boiler efficiency include fuel type, combustion efficiency, and heat transfer efficiency.
Improving boiler efficiency can lead to cost savings and reduced environmental impact...
A deaerator is a device used to remove dissolved gases, such as oxygen, from feedwater in a boiler system.
Deaerators help prevent corrosion in the boiler system by removing dissolved gases that can cause pitting and scaling.
They also help improve the efficiency of the boiler by reducing the amount of oxygen in the feedwater, which can cause oxygen pitting and boiler tube failures.
Deaerators typically consist of a ...
There are various types of boilers used in different industries and applications.
Fire-tube boilers: Water is heated inside the tubes and hot gases pass through the tubes.
Water-tube boilers: Water flows through tubes and hot gases surround them.
Electric boilers: Heat is generated by electric resistance heating elements.
Package boilers: Pre-designed and assembled units for easy installation.
Condensing boilers: Recov...
