Fire tube boiler designing Fire tube boilers operate by sending combustion/flue gas by using a combination of straight tubes flanked by trouble held in identical vessel. Often identified by the variety of passes used (say for example a 3-pass or 4-pass fire tube boiler), this refers to the variety of times combustion gas flows the capacity of the pressure vessel mainly because it transfers heat on the water. A wet-back fire tube boiler utilizes a water cooled publish zone (end closure). A dry-back design depends on fire brick or refractory lining to avoid the conclusion closure from overheating. Fire tube boiler Fire tube boilers cost typically less in advance than water tube boilers, and gives lower operating costs when compared to a similarly sized water tube boiler. Fortunately they are simpler to maintain due to better fireside access and their efficient straight tube design. Fire tube boilers are equipped for approximately 3000 HP / 450 PSI having a single burner. Though smaller and more compact in design than water tube boilers of similar size, they will be more difficult to reach operating temperatures from the cold start but not handle steam demand fluctuations well once running.
