Choosing The Right Boiler: Watertube vs. Firetube - Boiler

Jun 13, 2013 · Choosing The Right Boiler: Watertube vs. Firetube. In watertube boilers, the arrangement is reversed. Instead of the water being outside the tubes, it circulates inside the tubes and is heated externally by the combustion gases. Fuel is burned inside the furnace, which heats the water in the steam-generating tubes.

Industrial boiler technology for beginners

The heart of an industrial boiler system is a hot water or steam boiler operated with a certain kind of fuel. The boiler heats up or evaporates the water inside it, which is then transported to the consumers via pipe systems. In case of hot water the transport energy is generated by pumps, in case of steam the transport is based on inherent pressure.
