Boiler Systems | ERK Energy Systems

Fire Tube Boilers. Fire tube boilers are the backbone of low pressure steam and hot water applications. The flue gases pass through the furnace and various smoke tubes. Typically, such boilers provide saturated steam or hot water. However, superheated steam supply is possible. With ERK Tubes such boilers can be very compact and low cost.

Superheater - Wikipedia

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet
