Steam compressor

Spilling steam compressors generate higher-pressure steam from existing low-pressure steam, so recovered excess steam becomes usable high-pressure steam without installing an additional boiler unit. They are oil-free, double-acting piston compressors in crosshead design, built specially for water vapour, with a multi-stage layout depending on the compression ratio and a modular design that adapts to a wide range of steam parameters. Two series are available, differing in stroke and nominal speed, and flow rate is controlled by a variable speed drive: either a three-phase asynchronous motor with frequency converter or an integrated steam engine drive for plants with several steam networks at different pressure stages. Applications include recovery of excess steam for thermal processes, exothermal processes in the chemical and petrochemical industries, and high-pressure steam injection, for example into a gas turbine combustion chamber to reduce NOx. Spilling supplies everything from the single compressor to complete units with the accessories needed to integrate it into the steam system.
