Burning Chicken Litter as Fuel

Chicken litter produced on site can now be cleared directly from the broiler sheds at the end of a crop and used to fuel a biomass boiler to produce heat for the next crop.

The Energy Innovations furnace and boiler, manufactured with proven litter burning technology by leading Austrian manufacturer Polytechnik Luft-und Feuerungstechnik GmbH ensures the litter is burnt in compliance with all UK and EU legislation for the on-farm burning of litter.

The boiler has been designed specifically to ensure the combustion complies with EU 592 / 2014: ‘the use of animal by-products and derived products as a fuel in combustion plants’. With a design first commissioned over 10 years ago, this design ensures high nitrogen and high moisture content chicken litter is reliably and consistently burnt without exceeding the regulatory emission limits or reducing the life time of the heat exchanger when burning fuels which would otherwise cause a reduction in the life of components.

The Toploader fuel handing system has been in use by Energy Innovations for several years and the specification used has been developed specifically to suit the handling of chicken litter. The surfaces in contact with the litter are all stainless steel with the walls of the bunkers being fully sealed concrete. All other parts of the top loader are hot dip galvanised. Similarly, the barn is designed specifically to resist the environmental pressures resulting from the storage of chicken litter in an enclosed building.  It is fully sealed and run at a negative pressure to ensure any gaseous emissions from the litter are drawn through the boiler and burnt off at over 850°C.  The cladding in the barn is insulated and coated with a resistant coating. All steels are fully galvanised, all purlins are wooden (as Z purlins can corrode).

Personnel access is through a sealed changing area with integral showers to avoid risk of any diseases in the litter of the previous crop being transferred to the next crop.

Remote monitoring, including cameras that can view the fuel store and the fire in the furnace together with a full on-going support package contribute to ensuring your plant complies with APHA regulations for the burning of litter.

Energy Innovations can assist with the submission of your application to the Animal & Plant Health Agency (APHA), who are the approving authority for this technology.
