Babcock Wanson completes Moy Park regenerative thermal oxidiser 25 November 2014

Babcock Wanson has completed commissioning the regenerative thermal oxidiser at food giant Moy Park's Grantham, Lincolnshire facility.

The new plant was ordered to provide for odour abatement for the site's six production lines, which handle poultry frying and oven-based cooking.

The new system replaces the existing catalytic thermal oxidisers, and has been designed to treat the complete cooking exhaust stream, whatever the process heat load.

Exhaust air is now fed through a heated matrix of ceramic honeycombs, entering the oxidiser at 60°C and reaching 850°C in the ceramics, with a small burner adding the final heat to get the stream to oxidation temperature.

Treatment includes passing through three towers operating on a fixed rotation, with clean, odour free air being released to atmosphere.

Moy Park says the new plant is ideal for its processes, allowing for up to 25,000 Nm3/h of cooking exhaust to be treated with minimal natural gas input.

It is also fully automatic, so means production lines can be switched on or off to meet requirements without having to adjust the oxidiser settings.

Babcock Wanson also designed a secondary heat recovery stage, which will provide up to 200kW of hot water from the clean exhaust air, so further increasing overall efficiency and reducing the site's carbon footprint.
