Merits And Demerits Of Fire Tube Boilers - Kainon Boiler

Fire tube boiler is relatively cheaper than water tube boiler. Disadvantages of Fire Tube Boiler: Steam output pressure cannot be very high since the water and steam are enclosed in the same vessel. The steam received from the fire tube boiler is not very dry. The efficiency of heat transfer is bad since the heat exchanger does not use thermal
