Feasibility of using low pressure steam for sootblowi

2010-3-25 · the high pressure steam produced by the boiler. Due to high energy costs in recent years, alter-native sources of steam for sootblowers have con-stantly been sought. One such source is the rela-tively low pressure steam, 150 to 300 psi, from a steam turbine. The main advantage of using this source of low pressure steam is that it is much less

US9927231B2 - System and methods for detecting

A boiler system includes a boiler having at least one heat exchanger having a surface on which a deposit may form. The boiler system further includes at least one retractable sootblower having a lance tube for carrying a high pressure fluid into the boiler. The lance tube is configured such that the high pressure fluid impacts the heat exchanger surface to effect a vibration in the boiler system.
