Moy Park installs odour-eater
24 Nov 2014
Food manufacturer Moy Park has commissioned a regenerative thermal oxidiser to reduce cooking process odours at its site in Grantham, Lincolnshire.
The facility is a processing site for breaded and ready-to-eat poultry, featuring six production lines.
Both frying and oven cooking methods are used at the site, which has grown rapidly over recent years. With this growth has come the need for improved odour abatement, given the site’s location close to Grantham town centre.
Industrial heat specialist Babcock Wanson designed, built and commissioned the regenerative thermal oxidiser, which has replaced the site’s catalytic thermal oxidisers.
The regenerative thermal oxidiser is capable of treating the complete cooking exhaust stream irrespective of the process heat load, and allows for up to 25,000 Nm3/h of cooking exhaust to be treated with the minimum of natural gas input.
The exhaust air from the cooking processes is fed through a heated matrix of specialist ceramic honeycombs. It enters the oxidiser at around 60°C and is heated to 850°C by the ceramics, with a small burner adding the final heat to get the stream to full oxidation temperature. The exhaust stream is treated by passing it through 3 towers which operate on a fixed rotation thereby ensuring a constant treatment profile.
The clean, odour-free air is then released to atmosphere.
Installation was completed by Babcock Wanson using much of the site’s existing ductwork to help minimise disruption to Moy Park’s busy schedule.
