Heat recovery & effect integration for forced-circulation evaporation
Recover heat within a defined duty. Define its duty within the complete food-concentration circuit.
MODULE 07
Effect count describes the evaporation arrangement, while TVR and MVR describe vapour recompression. They can be evaluated together. The circulation pump remains an additional electrical load regardless of the heat-recovery choice.

| Input | Output | Interfaces |
|---|---|---|
| A specified vapour or utility stream with known pressure and quality | Heating duty to an effect or connected process | Effect train, TVR or MVR equipment where applicable, condensate and start-up utilities |
Specification inputs
| Parameter | Condition to state |
|---|---|
| Thermal balance | Feed preheat, evaporation, losses, condensate recovery and residual cooling. |
| TVR conditions | Motive steam pressure, suction condition and required operating range. |
| MVR conditions | Vapour flow, pressure rise, boiling-point elevation and electrical service. |
| Comparison basis | Same feed, outlet solids, evaporation rate, hours and quality constraints. |
Maintenance access
Assign access and service responsibility for compressors, ejectors and associated instruments. Include start-up and off-design operation in the review. Assess downtime on the actual production schedule.
Selection limit
No fixed energy-saving percentage is inferred from “forced circulation”, multiple effects or recompression. Compare measured or guaranteed quantities within a common boundary.
