Locomotive Boiler: Definition, Parts, Working Principle

The water level indicator is used to indicate the water level in the boiler and to maintain the water at a constant level because the production of steam majorly depends on the quantity of water. In case the water level is below the normal level then water will be pumped from the reservoir by the operator. Locomotive Boiler Working Principle

How do heat exchangers work? - Explain that Stuff

May 04, 2021 · Hot water is piped through it from a gas central heating boiler, giving up some of its heat to the air in the room in the process and returning to the boiler for more. This is a sort of heat exchanger because the heat from one fluid (the hot water in the pipe) is being given to another fluid (the cold air in the room) without the two fluids mixing.
