Wood Fired Shell Tube Hot Water Boiler

Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler water.Shell boilers, also known as flame tube or flue tube boilers, represent a robust and durable boiler technology which, due to its given water/steam volume, can react particularly well to fluctuating load conditions and peak performance.There are two basic types of boilers: firetube and watertube. The fundamental difference between these boiler types is which side of the boiler tubes contain the combustion gases or the boiler water/steam.
