Advantages and Disadvantages of Water Tube Boilers over Fire Tube Boilers: Advantages: 1. Steam can be raised more quickly: In water tube boilers, the ratio of water content to the steam capacity is comparatively less than the fire tube boiler. Hence water tube boilers can quickly generate steam at the required pressure than the fire tube boiler. 2. Steam at higher pressures can be produced
What is Water-tube Boiler? - Water-tube boiler is a type of boiler with pipes containing circulated water, which is heated by a fire on the outer side of the pipe. The water-tube boiler has the opposite design with the fire-tube boiler. This boiler circulates water through the pipelines with the heat source coming from the furnace.
Shell and tube boilers are also referred to as fire tube or smoke tube boilers. Fire tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate.
Comparison between Fire tube and Water tube boilers A boiler is a device used to generate s team at a desired pressure and tem pe rature by transferring heat energy produced by burning fu el to water to change it to steam.
