Boiler Development in Factory Industries
Perhaps not many people know that calderas is a vessel/container which contains water or other fluid to be heated. The heat energy from the fluid is then used for various purposes, such as for steam turbines, heating, steam engines, and so on. In the process of energy conversion, the boiler has a function to convert the chemical energy stored in the fuel into heat energy which is transferred to the working fluid. The heat given to the fluid in the boiler comes from the combustion process with various types of fuels that can be used, such as wood, coal, diesel/petroleum, and gas.
The following are some types of boilers that are widely used in industry:
– Pot Boiler
It is the simplest design boiler in history. Introduced in the 18th century, using large volumes of water but only able to produce at low pressure. This boiler uses wood and coal fuel. This type of boiler does not last long because of its very low efficiency.
– Fire-tube boiler
In the next development, there was a new boiler design, a fire-pipe boiler. This boiler has 2 parts in it, namely the tube/pipe side and barrel/barrel side. On the side of the barrel contains fluid/water, while the side of the pipe is where the combustion takes place. Fire-pipe boilers usually have low water vapor production speeds but have a larger water vapor reserve.
– Water-Tube Boilers (Pipe-Water Boilers)
Just like a fire-pipe boiler, a water-pipe boiler also consists of a pipe and barrel section. But the side of the pipe is filled with water while the barrel side is where the combustion process takes place. This type of boiler has high speed in producing water vapor, but not much has a reserve of water vapor in it.
– Combined Pipe-Fire Boilers with Firebox Pipe-Water
This type of boiler is a combination of a pipe-fire boiler with a water pipe. A firebox in it contains pipes filled with water, the water vapor produced flows into the barrel with the pipes inside. This type of boiler is applied to several steam trains, but it is not very popular to use.
