TVR EVAPORATORS
TVR evaporators use Thermal Vapour Recompression to recompress a portion of the vapour from the vapour separator and mix it with the steam to heat the first stage.
Process for TVR evaporator
Thermal Vapour Recompression (TVR) normally takes place across one or more stages by utilizing medium or high pressure steam in an ejector which recycle a portion of the vapour from the vapour separator and mixing it with the steam. This mixture is used for heating of the first evaporation stage.
The steam consumption for a TVR evaporator will vary between approx. 0.3 - 0.07 kg steam per kg water evaporation depending on the number of stages over which the recompression takes place.
This design provides for less costly machinery than straight steam heated designs but requires motive steam pressure.
Thermo compressors
Thermo compressors are designed to recycle heat energy by capturing and recompressing waste steam for use elsewhere.
Thermo compressors, like ejectors, have no moving parts. The mechanical design consists of a steam chest, nozzle holder, nozzles, and diffuser.
The thermo compressor uses high pressure steam, as a motive fluid, which enters the steam chest and expands through the nozzle.
The high-velocity steam then entrains the waste steam, into a mixing chamber where the fluids are combined.
The mixed fluids are then recompressed to an immediate pressure through the diffuser, which acts as a nozzle in reverse, reconverting velocity energy to pressure energy.
Thermo compressors are designed for applications in the food, petroleum, chemical, power, and paper industries. Thermal recompression is typically applied in the dairy and juice industries to recapture and reuse steam from evaporators during the concentration process.
All thermo compressors are custom designed and performance tested to meet our client’s exacting specifications.
