Fire Tube Boiler Problems

Westinghouse Fire Tube Boiler

The Fire Tube Boiler is manufactured in Massachusetts with the highest quality materials. The 316L stainless steel fire tube heat exchanger is more resistant to corrosion in comparison to typical copper or aluminum heat exchangers. 316L stainless steel lasts longer and is virtually maintenance free, while also facilitating the transfer of heat more efficiently.

Comparison between gas-fired fire tube

In a fire tube boiler, the threaded smoke tubes are surrounded by water. While passing through the threaded smoke tubes, the high temperature flue gas heats the water or vapour and ultimately produces steam or hot water. Water tube boilers should adopt water treatment equipment to avoid the problems caused by boiler scale. Conclusion:
