High Pressure Seamless Carbon Steel Heat Radiant Superheater Coil

High Pressure Seamless Carbon Steel Heat Radiant Serpentine Tube Superheater Coil

Superheater Coil Description

For boilers in large power stations, superheaters and reheaters are necessary parts, to a large extend, they have influnced the safety and economy of boilers. Superheaters are the heating surfaces which heat the main steam from the surnatured temperature to the rated superheated temperature, and the reheaters are the heating surfaces which heat the exaust from the steam turbine high pressure cylinder to a certain temperature.When running conditions like boiler loads, coal types change, it is to adjust them to make sure the outlet temperature at the rated level of -10-+5 degrees.

1. Material composition: It is made up of snake-like tubes (carbon steel, alloy steel or heat-resistant steel, etc.) and collection boxes and other supporting material. Tubes generally have 32, 38, 42 or other types of specifications, according to user's needs separately.
2. Arrangement: vertical or horizontal layout.
3. Features: beautiful appearance, size, accuracy, first-class bending and welding technology, first-class detection equipment.

Superheater
Fossil fuel power plants often have a superheater section in the steam generating furnace.The steam passes through drying equipment inside the steam drum on to the superheater, a set of tubes in the furnace. Here the steam picks up more energy from hot flue gases outside the tubing, and its temperature is now superheated above the saturation temperature.

Reheater
Power plant furnaces may have a reheater section containing tubes heated by hot flue gases outside the tubes. Exhaust steam from the high-pressure turbine is passed through these heated tubes to collect more energy before driving the intermediate and then low-pressure turbines.
