Chat OnlineA series of cracks on the tube surfaces thus developed propagate into the tube wall. The long-term appearance is like a series of circumferential cracks over the tube length. This type of tube failure is normally observed on furnace wall tubes of coal-fired once-through boiler designs, but are also occasionally found on tubes in drum-type boilers.
Chat OnlineTypes of Watertube Boilers. There are three main types of watertube boilers, each named for their relative shape. O-Type. This boiler has the steam and water drums one above the other. The water pipes are curved between the drums, creating an O shape. D-Type. Water is sent from the water drum to the generating tubes, which form the fire box.
Chat OnlineThe length of the probes is determined by the boiler manufacturer. My experience is the low water shutdown probe is 1½ to 2½ inches above the water tube boiler connections. The basic indication of the drum water level is commonly shown in a sight gage glass (bull's eye) connected to the boiler drum.
