Supe Heater Coils

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 (a few metres to some hundred metres).

Types of Superheater –

• A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation.
• A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters.
• A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes. This type of superheater is rarely if ever used, because of poor efficiency and steam quality that is not better than other superheater types.

Abbtas have manufacturer & supplied many Superheater made up of snake-like Boiler quality tubes (carbon steel, alloy steel or Stainless steel ,heat-resistant steel, etc.) and collection boxes and other supporting material. Tubes generally have OD 32 to 76.2 and 3 mm to 12 mm or other types of specifications & sizes for metal temperature ranging up 600 C and for Boilers of 5 to 800 MW Capacity according to user's needs separately.
