Heat and Mass Balance - EnggCyclopedia

Heat and mass balance is a document produced by process design engineers while designing a process plant. Sometimes heat and mass balance is not a separate document but appears alongside the Process Flow Diagram (PFD). A heat and mass balance sheet represents every process stream on the corresponding PFD in terms of the process conditions.

Assessment of waste preheater gas and dust bypass systems ...

Factors that affect the heat transfer rate in the preheater include: bypass size, calcination degree (CD), temperature, raw mix moisture content, and the amount of excess air (which limits gas production in the system). The mass balance of each phase (solid raw mix and gases) is affected by the reactions taking place in each cyclone.
