Waste Heat Recovery Basic Data

For both the waste heat stream, and the stream receiving the heat, the data (in addition to ambient conditions) needed to evaluate waste heat recovery are:

• The flow rate
• The specific gravity of the fluid
• Temperature
• Chemical composition
• Corrosive capabilities
• Depositing characteristics
• Any temperature limitations or control requirements

Use average conditions for economic considerations, but evaluate variations for critical design conditions.

Review data on the stream receiving the heat to make sure that it is a valid use. The amount of heat that can be recovered from any heat source is meaningless unless valid uses exist. As a prime example, there is no benefit from producing more low pressure steam from waste heat when the plant is already venting low pressure steam most of the time.
