Thermocompressor - Import export

Large industrial plants often vent significant quantities of low pressure steam to the atmosphere, wasting energy, water, and watertreatment chemicals. Recovery of the latent heat content of lowpressure steam reduces the boiler load, resulting in energy and fuel cost savings. Lowpressure steam's potential uses include driving evaporation and distillation processes, producing hot water, space heating, producing a vacuum, or chilling water. If the steam pressure is too low for the intended application, a steam jet thermocompressor can boost the pressure and temperature to the required level. Operating Principles - Thermocompressors and ejectors operate on the same thermodynamic and physical principle energy contained in high pressure steam can be transferred to a lower pressure vapor or gas to produce a mixed discharge stream of intermediate pressure.

Boosting Steam Pressure and Temperature with Thermocompressors Single- or multi-stage Thermocompressors are used to boost low-pressure vent steam to a useful higher pressure and temperature. When high-pressure motive steam is available, Thermocompressors can be economically used for compression ratios up to 6:1 (absolute pressure of supply steam/suction steam). High-pressure motive steam supplied to the Thermocompressor expands in a converging-diverging nozzle to convert pressure energy to kinetic energy. Vent steam supplied to the suction port is entrained into this low-pressure/high-velocity jet, where mixing occurs. The diffuser portion of the Thermocompressor shown in the figure reconverts the kinetic energy of the mixture back into pressure. The intermediate discharge pressure is between the pressures of the motive and low-pressure suction steam.

A Variable Flow Erectors are pneumatically / Electrically operated single nozzle ejectors, used to handle the variable suction ad discharge conditions wherein pneumatically / electrically operated needle goes in and out for precise controlling the flow rate based on pressure requirement. It is very useful when a low pressure steam is compressed to a higher pressure level.
