Are water tube boilers safer than fire tube boilers?
Summary The exhaust gas flow of the overheat fire tube boiler is 3Pass, with the rear combustion chamber in the wet combustion method, so that it has a very high heat absorption rate and since the fire tube is manufactured in wave shape, so the design can
connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be identified by the shape of the tube configuration, with the common types being called A, O, and D style boilers. The cast iron sectional boiler is neither fire tube nor water tube though it has some operating

Fire tube boilers are designed to transfer hot gases from the heating source and cycle these gases through tubes that circulate through a drum filled with water. This process effectively transfers the heat from the gas into the water, which effectively generates steam.
Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler."Boilers that operate higher than 15 psig are called "high-pressure" boilers.
In water-tube boilers, flue gases surrounding tubes heat water inside of the tubes. In fire-tube boilers, flue gases are inside of tubes, and water is in the shell around the tubes. Steam Applications. In steam applications, water quality is an important part of boiler selection. Steam boilers tend to be steel water-tube- or fire-tube-type ...
Fire Tube Boiler: In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam pressures.
