Textile Line Cut Steam Use 20%
Switching to Controlled Thermocompressors
20%
Steam Saved
A continuous textile line with a 3-row dryer stage (each row 12 drum dryers) was originally valve-controlled, driving up steam demand & limiting speed/quality. A retrofit replaced control valves with baelz 590 controlled steam thermocompressor to stabilize drying & save energy.
The Challenge
With valve control, internal steam condensate films stayed thick inside the drums, slowing heat transfer & capping production speed.
Baseline parameters on the section were
Motive = 5.5 barg
Discharge = 3 barg
Steam Load = 200–600 kg/h
depending on textile material—conditions that left efficiency on the table.
The Solution
The plant replaced the control valves with steam thermocompressor.
After retrofit, operating points settled at
Motive = 5.5 barg
Suction = 1.5 barg
Discharge = 2 barg. (1 Barg Lowered)
Steam Load = 20% Lower (As per end customer)
The Results
20% steam saved (As per End Customer)
“Monthly steam consumption” improved from 2.6 t → 2.2 t (as reported in the case).
Higher production speed & better drying quality from thinner condensate films & steadier pressure.
Why This Works
A controlled steam jet thermocompressor acts as a steam compressor without moving parts.
Correct thermocompressor design & nozzle design lift internal velocities, minimize film thickness, & stabilize setpoints
—delivering heat transfer solutions that reduce steam per meter processed while enhancing line runnability.
When paired with good steam & condensate practice (e.g., steam separator, flash steam routing, condensate & flash steam recovery system), savings compound across the section.
Takeaway
If your dryers are valve-controlled & you’re fighting venting or high steam per kg of fabric, a controlled steam thermo compressor can be a fast, low-maintenance route to saving energy:
recover with steam jet ejectors, improve drying, & unlock speed—without adding rotating machinery.
