    摘要： 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.

    摘要： A method and system for measuring a weight of a deposit that forms on a tube bank independently-suspended by one or more hanger rods within a boiler are characterized by having one or more strain sensors, with each strain sensor affixed to a separate hanger rod. The strain sensors are connected to a logic circuit for reading strain readings from the strain sensors and calculating the weight of the deposit as a function of the strain readings.

    摘要： A segmented smelt spout comprising an assembly of different casting shapes wherein one shape constitutes the base segment, which is installable in a chemical recovery unit, and the other shapes are a combination of straight and curved cast segments, which can be used in different combinations to obtain varying spout angles and lengths with the latter segments being supported off the base segment and being held together by a tensioning means that maintains contact between the mating surfaces of each segment while permitting each individual segment to expand and contract thermally.
