Steam recovery cuts energy by 20%
February 1st 2006

A Spirax Sarco flash steam recovery system is delivering direct energy savings of 10% plus a further 10% in indirect savings at De Mulder & Sons in Nuneaton, one of the UK's largest processors of meat and poultry residues. De Mulder & Sons uses around 25t/hr of steam to dry and sterilise animal products. Before the new system was installed, the resulting flash steam from the returning drier condensate was vented to atmosphere.

The flash steam recovery system transfers the energy in the condensate or flash steam to boiler feedwater raising the temperature to around 130°C rather than the 90°C achieved before. "The boilers work closer to their optimal firing capacity, saving an extra 10% on top of the 10% saved directly by waste heat recovery,"explains De Mulder & Sons' operations director Rob Ratcliffe.
