title
The Environmental and Energy Systems division of Dürr Systems has developed the Heat Storage Shutdown (HSS) mode, which optimizes the energy savings from almost any off-production regenerative thermal oxidizer (RTO). According to the company, this method is significantly more energy efficient than the set-back or idle mode. HSS mode:
- Enables the RTO fan and burner to be shut down while the unit stores its remaining heat energy in the combustion chamber.
- Retains an elevated temperature from which to return to production ready status. Depending on the amount of time the unit is off-line, the combustion temperature only diminishes 300-600°F below set-point.
