Man Hole. Stop Valve. Blow off valveLet’s study one by one, Shell:A shell contains water inside it as well as a tube. The transfer of heat between water takes place in the shell.And also the shell is like it covers all the components of the boiler and it is also called the main body. Grate:It is a door form which the fuel is provided for burning and generating heat.The grate is located at the bottom of the furnace. Furnace:A furnace works like a mediator you know why? Because it is connected between the fire tube and the combustion chamber.Here fuel burns and produces Heat.
Combustion chamber:Here in the combustion chamber the fuel burns and produces heat which is then supplied to the tube here water is surrounded.The combustion chamber is connected to the furnace. Ash pit:Here ash of fuel which is completely burned and no use inside the boiler. Chimney:The chimney is here for releasing the exhaust gases to the atmosphere. Smokebox:The smokebox is provided here to collect the smoke and further sends it to the chimney. Water level indicator:This is an instrument which gives the detail of the water level of the boiler. This also works when water exceeds the limit or water down the limit. Safety Valve:The safety valve is another type instrument which is used for safety purpose and This also works when no other indicators work.
Cornish BoilerThe working substance here is.Lets study working,At the grate, the fuel which is coal is provided and it sends to the furnace.Here we burn the fuel by providing some amount of fire to it. So as we know this is a single large tube boiler.Burning of coal produces the heat which is then sent to the tube and here water is surrounded.Why water is surrounded automatically? Because we supply water here and with the use of an instrument, water level indicator we measure the level of water. Meanwhile here the burning coal ash comes to the ash pit and from here it comes to the smokebox and the gas will release to the chimney to the environment.And we extract the ash from the system and clean this.
