Abstract: 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.

Abstract: The invention relates to a continuous steam generator comprising a surrounding wall which forms a gas draught and whose lower section is configured from gas-tight evaporator tubes that are welded together and whose upper section is configured from gas-tight superheater tubes that are welded together. According to the invention, superheater tubes are connected downstream of the evaporator tubes on the flow medium side by means of a water separator system. The aim of the invention is to provide a system with particularly high degree of operational flexibility even in the start-up and off-peak periods, while keeping the production and installation expenditure relatively low. To achieve this, the water separator system comprises a large number of water separator elements, each of which is connected downstream or upstream of less than ten evaporator tubes, preferably one tube and/or less than ten superheater tubes, preferably one tube on the flow medium side.

Abstract: A fuel-fired water heater is provided with a premixing type main burner and an associated pilot burner for igniting it. A specially designed protective system is operative to detect a flame flashback burning condition in the main burner and responsively shut down the water heater. In one embodiment thereof, the protective system uses main burner body heat to melt a portion of a fuel supply line connected to the pilot burner during a flame flashback condition in the main burner. Such melting responsively causes an associated fuel supply valve to close and terminate water heater operation. In a second protective system embodiment a normally closed pressure switch is opened, thereby shutting down the water heater, when the switch detects a pressure indicative of a flame flashback condition in the main burner.
