Höyrykattilat

Höyrykattilat, or steam boilers, are enclosed vessels that heat water to produce steam. This steam can then be used for various purposes, such as powering turbines in power plants, heating buildings, or driving machinery in industrial processes. The fundamental principle of a steam boiler involves transferring heat to water, causing it to vaporize and increase in pressure.

There are several types of steam boilers, broadly categorized by their design and how the heat transfer occurs. Fire-tube boilers are common for lower pressure applications, where hot combustion gases pass through tubes surrounded by water. Water-tube boilers, often used for higher pressures and larger capacities, have water flowing through tubes that are heated by the combustion gases on the outside.

The operation of a steam boiler requires careful control of water level, pressure, and temperature to ensure safety and efficiency. Safety features like pressure relief valves are critical to prevent over-pressurization. Regular maintenance and inspection are also essential to detect any potential issues and ensure reliable performance. The efficiency of a boiler is measured by how effectively it converts fuel energy into steam energy. Modern steam boilers often incorporate advanced control systems and energy-saving technologies to optimize their performance and minimize environmental impact.
