- The Cochran Boiler: This vertical boiler was made by Cochran and Co. of Birkenhead in England. It has a cylindrical outer shell with a domed hemispherical top and a one place hemispherical fire box in the bottom of the shell. It was fired through a fire hole at one side. From the other wide of the firebox a circular flue took the gases upwards at an angle to a combustion chamber inside the back of the shell. A large number of fire tubes were inserted horizontally across the boiler. They opened in to the wall of a partly external smoke box on the boiler front, the chimney flue extending from the smoke box top.

- Diameter of boiler: 5 feet.
- Number of fire tuber: 86
- Steam Engine Horizontal Type: This is a single cylinder and double acting type steam engine introduced in the beginning of 20th century. The steam chest is operated by a D slide valve. Steam pressures up to 100 PSI can be used and a power of 10 HP can be produced. This steam engine was used for pumping water and for driving small machines.
- Steam Boiler: Meary Weather and Jakemans Patent number: 2405: This boiler was used in the mechanical engineering laboratory of the UVCE, Bangalore. (Donated by Bangalore University in 1990) The modern boiler like its earlier fore-runners is basically a closed vessel supplied with water which is transformed into steam by heat. But because the pressure at which the steam is generated determines the temperature of the water inside the boiler, the ability of the boiler to withstand pressure is critically important. The main types of the boiler are:
- The shell boiler: The shell type boiler is cylindrical with internal flues and is often set in brickwork containing return flues which carry the heat round, to heat the outside of the boiler sheet. The Lancashire boiler with two furnaces is typically of this class.
- Fire tube boiler: In fire tube boilers the hot gases circulate through tubes to heat the water surrounding the tubes. Tube arrangement may be vertical, horizontal, or inclined. The fire tube boilers are very suitable for the economic generation of steam where there was a reasonably steady power demand and were used mostly frequently for locomotives and marine engines. The Cochran boiler is a typical fire tube boiler.
- The water tube boiler: In water tube boiler the hot gases surround the tubes and the water flows through the tubes. John Blakey designed the earliest of the water tube boilers in 1774. The water tube boiler is used to run stationary engines in factories or power plants. Babcock Wilcox boiler is a typical water tube boiler.
