The temperature of the flue gases leaving the regenerator is usually between 300 and 600°C, and can be used to recover steam. Capturing the waste heat can be done before the flue gas cleaning (with subsequent cleaning) or after gas cleanup (Worrell et al., 2008. p.60). The amount of heat that can be recovered is dictated by the outlet temperatures, which is limited to around 200°C in order
