    • A cleaning system and method for cleaning heat transfer surfaces in a boiler using a temperature measuring system for measuring and monitoring wall temperature of an annular wall of the tube of a lance of one or more sootblowers. Controlling a flow of steam or other fluid through the tube during the cooling portions of the strokes based on wall temperature measurements from the temperature measuring system. Infrared or thermocouple temperature measuring systems may be used. The steam or other fluid may be flowed at a default flowrate that may be substantially zero until the temperature measuring system indicates the wall temperature of the annular wall begins to exceed a predetermined temperature limit which may be the softening point of the annular wall. Then the steam or other fluid is flowed at a rate greater than the default flowrate.
    • 一种清洁系统和方法,用于使用用于测量和监测一个或多个吹灰器的喷枪的管的环形壁的温度的温度测量系统来清洁锅炉中的传热表面。 基于来自温度测量系统的壁温测量,在笔划的冷却部分期间控制蒸汽或其它流体通过管的流动。 可以使用红外或热电偶温度测量系统。 蒸汽或其他流体可以以基本为零的默认流速流动,直到温度测量系统指示环形壁的壁温开始超过可以是环形壁的软化点的预定温度极限。 然后蒸汽或其他流体以大于默认流量的速率流动。
