9 De-Superheaters STEAM DE-SUPERHEATERING : The most practical way of reducing the superheat value of steam is by the direct addition of water. To achieve temperature stability of the conditioned steam and prevent thermal shock in downstream pipes, the cooling water must be atomized. It is also necessary to have a correct mix of superheated steam and cooling water. Variable Nozzle Fixed Nozzle Safety Relief Valves Safety relief valve VSEO, full lift spring loaded Liquid Thermal Expansion service Valves are available in 12 sizes as per API-526 Orifice sizes (EA-RA) and ANSI flanges covering set pressure ranging from 1.2 bar to 204 bar. A variety of materials are available to suit temperature range up to 550C 31
