Fire Tube or Shell Boilers. In fire tube boilers the flame and heat gases from combustion are confined within tubes arranged in a bundle within a water drum. Water circulates on the outside of the tubes. As the water changes to steam it rises to the top of the boiler drum and exists through a steam header.

Boiler feedwater - Wikipedia

Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it then goes back to the steam drum to complete its cycle. The feed water is
