Andritz, headquartered in Graz, Austria, will supply a 1,200 tds/d (tons of dry solids per day) recovery boiler to paper and packaging group Mondi Frantschach at its mill in St. Gertraud, Austria. Andritz will deliver the entire boiler plant with auxiliaries, including instrumentation and electrification. The project includes a process control system for the boiler island, including the safety system and integration to the existing mill.

The recovery boiler will replace two old boilers and incorporate the vertical air-combustion system to ensure the lowest possible emissions. Steam values are designed for an operating temperature of 896°F (480°C). For possible future needs, space will be allocated for a chloride and potassium removal system. The design also enables the future addition of a flue-gas cooler and/or a flue-gas scrubber, if needed. Startup is scheduled for second half of 2013.
