Boiler - Wikipedia

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications,[1][2] including water heating, central heating, boiler-based power generation, cooking, and sanitation.Heat sources· Materials· Energy· Boiler efficiency· Configurations· SafetyThe History of Steam Generation - Energiteknik |· PDF 文件Supercritical boiler..11 Graphs and timelines of development in boiler technology ..12 The History of Steam Generation - 10 Figure 12: Different methods of welding boiler tubes.
