höyrykattila

Höyrykattila, often translated as steam boiler, is a closed vessel in which water is heated under pressure to produce steam. This steam can then be used for various purposes, including generating power, heating buildings, or driving machinery. The fundamental principle of a steam boiler is to transfer heat from a fuel source to water, causing it to boil and transform into steam.

There are several types of steam boilers, broadly categorized by how heat is transferred. Fire-tube boilers are common in smaller applications where hot gases from combustion pass through tubes submerged in water. Water-tube boilers, typically used for higher pressures and capacities, have water flowing through tubes that are heated externally by combustion gases. The choice of boiler type depends on factors such as required steam pressure, steam output, fuel availability, and installation space.

Safety is a paramount concern in the design and operation of steam boilers. They are equipped with numerous safety devices, including pressure relief valves, water level indicators, and temperature sensors, to prevent over-pressurization and other hazardous conditions. Regular inspection and maintenance are essential to ensure the safe and efficient operation of any steam boiler system.
