Calderas is a machine that functions to convert water or fire into steam. The process of changing water into steam occurs by heating water in the pipes by utilizing heat from the fuel combustion. Burning is carried out continuously in the combustion chamber by flowing fuel and air from outside. The steam produced by the boiler is superheated steam with high pressure and temperature. The amount of steam production depends on the heat transfer surface area, flow rate, and heat of combustion given.

Like other industrial equipment, calderas have components that help convert water or fire into steam. Boilers are widely used especially in industrial plants because they are capable of being an alternative steam power plant. The components contained in boilers include:

– Steam Drum
Steam drums function as a reservoir of hot water and where steam is formed. This drum holds saturated steam along with water with a ratio between 50% water and 50% steam. to avoid so that the water is not carried away by steam, then it is fitted with barriers, water that has a low temperature will drop down and high-temperature water will rise upwards and then evaporate.

– Air Heater
This component is a tool that serves to heat the air used to blow fuel so that it can burn completely. The air to be exhaled, before passing through the water heater has the same temperature as the normal air temperature (outside temperature) which is 38 ° C. However, after going through the air heater, the temperature of the air will increase to 230 ° C so that it can be used to eliminate the water content contained in it because water vapor can disrupt the combustion process.

– Dust Collector
This section serves to capture or collect the ash in the combustion stream until the dust that follows the exhaust gas. The advantage of using this tool is the combustion gases which are discharged into the air free of dust. The reason is that dust can pollute the air in the surrounding environment.
