Introduction to Steam Boilers
Steam boilers are essential industrial equipment that play a crucial role in various sectors such as power generation, manufacturing, chemical processing, and food production. A steam boiler is a closed vessel in which water is heated by the combustion of fuels (such as coal, oil, gas) or other heat sources until it turns into steam. The steam produced can be used for heating, powering turbines to generate electricity, or as a process medium in industrial manufacturing. The efficiency, reliability, and safety of steam boilers are of great significance to the normal operation and economic benefits of enterprises.
