| Description: | Steam Desuperheater are designed to reduce the temperature of super heated steam to produce lower operating temperatures. The majority of installations fall into these typical installations. Power plant requirements for desuperheated steam supplying units having limited operating temperatures such as auxiliaries, heating systems, heat exchangers and more recently, dump stations. To improve heat transfer of surface-type exchangers. Reduction and control of super heated steam, where excess temperatures will harm the product. Use on boilers, either between super heater stages or at boiler exit, to control super heat temperatures at partial loads. Use as bypass of bleeder or back pressure turbines to maintain balance between process steam and power requirements. Miscellaneous applications where balancing or make-up steam is required in reduced pressure systems in refineries and process plants In operation the majority of our Desuperheaters require the water pressure to be equal to the main line steam pressure with the exception of the Type 6910 and Type 6905 where the water pressure must be at a greater pressure to the main line steam. Water is syphoned in to the combining tube assembly, where it is heated and then mixed with a small proportion of steam passing through the throat region. This is then introduced in to the steam line as a finely atomized mist which alleviates the requirements of thermal liners and impingement shields. Desuperheater ion is usually defined by the operating characteristics and required duty. Our specific Desuperheater types can be seen below: | |
