Cochran boiler: parts, working, uses, advantages, limitations with PDF

A Cochran boiler is a vertical axis, multi-tubular fire tube boiler that operates at low pressure having natural circulation. The Cochran boiler is portable and has a thermal efficiency of about 70% when coal-fired and 75 % when oil-fired. The Cochran boiler is a modified form of the simple vertical boiler and has higher efficiency than that of

Condensing_boiler

Condensing boiler. A condensing boiler is a hot water heating device designed to recover energy normally discharged to the atmosphere through the flue. When a condensing boiler is working at peak efficiency the water vapour produced by the burning of gas or oil in the boiler condenses back into liquid water - hence the name "condensing boiler".

Working Of Boiler- Parts, Efficiency, Classification And …

The boiler is a closed vessel in which the water is stored. Hot gases are produced by burning fuel in the furnace. These hot gases are made to come in contact with the water vessel where the heat transfer takes place between the water and the steam. Therefore, the basic principle of the boiler is to convert water into steam by using heat energy.
