A boiler is a closed vessel in which water or other fluid is heated.

• Boilers are used to generate steam or hot water for heating or power generation.

• They come in various sizes and designs, including fire-tube, water-tube, and electric boilers.

• Boilers require regular maintenance to ensure safe and efficient operation.

• Examples of industries that use boilers include power plants, hospitals, and manufacturing facilities.

A multi-tube boiler is a type of boiler that has multiple tubes for the passage of hot gases and water.

• A multi-tube boiler consists of several tubes through which hot gases and water pass.

• These tubes are arranged in a way that maximizes heat transfer and efficiency.

• Examples of multi-tube boilers include Babcock and Wilcox boiler and Cochran boiler.

Distillation is a process used to separate components of a liquid mixture based on differences in boiling points.

• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Common examples of distill...read more
