Energy-efficient steam jet compressors.

Thermocompressors Kadant steam jet thermocompressors are designed to recirculate steam or boost lower-pressure steam for reuse in a variety of process applications in pulp and paper, petrochemical, food processing, desalination, and specialty chemical production. How thermocompressors work Thermocompressors are designed to accurately mix lower-pressure steam with higher-pressure steam. The higher-pressure motive steam entrains the lowerpressure steam and increases its pressure. The motive steam is introduced through the nozzle of the thermocompressor. As the nozzle opens, the high velocity motive...

High-efficiency thermocompressors In addition to retro-fitting existing steam jet compressors, Kadant also provides high-efficiency thermocompressors for improved energy utilisation. Based on extensive product development, modeling, testing, and field applications, Kadant’s high-efficiency thermocompressor offers entrainment ratio improvements of up to 25% over conventional steam jet compressors.

Thermocompressor Sizing The following charts can be used to estimate the size of a thermocompressor. The size is based on the motive, suction, and discharge steam pressures and the required steam flow. The following parameters are used for these estimates: P = Atmospheric pressure (absolute) = 1 bar (typical) Pm = Motive steam pressure (absolute) = gauge pressure + atmospheric pressure Ps = Suction steam pressure (absolute) = gauge pressure + atmospheric pressure Pd = Discharge steam pressure (absolute) = gauge pressure + atmospheric pressure Mm = Motive steam flow rate Ms = Suction steam flow...
