ProcessSustainable Poultry Productionbhsl have miniaturised fl uidised bed technology to enable its use in an on farm situation.Litter from one batch provides clean, dry, renewable heat to sustain the next batch. Poultry litter is a valuable fuel - the litter from 1 chicken can provide the heating needs of 3 chickens, allowing the remainder to be used for electricity generation. The enhanced environmental conditions not only provide energy savings but provide performance and bird welfare benefi ts. Producer margins can be increased several fold, more where renewable subsidies are available.Environmental benefi ts include low carbon production, reduced ammonia emissions and ground water protection by controlled ash recycling.Freedom from future oil price movements provide a uniquely sustainable system, where growers can reap the benefi ts of coupling food production with energy production.bhsl Service Management & AssurancePeace of mind and fi xed energy costs.DescriptionThe bhsl technology is delivered as a managed service to the customer. Low calorifi c biomass has a high ash content and a continuous maintenance plan is required for trouble free operations.Benefi ts9 24/7 remote management by the bhsl Operations Centre9 All planned and unplanned maintenance by local staff managed from Operations Centre9 Fixed costs for term of contract, including all parts and labour, so growers can accurately price in the energy costs of productionOptimalVentilationBiosecure StorageFluidised Bed Combustion (FBC)DescriptionOptimum ventilation provides more heat and draws a greater volume of air through the house in order to manage house humidity. Gasses associated with LPG combustion are no longer present, resulting in dryer litter and better growing conditions.Benefi ts9 Improvements in Food Conversion Ratio (FCR)9 Reduction in common skin irritations such as hock burn and footpad dermatitis9 Reduced ammonia emissions as litter is dryer9 Improved working conditions for staff 9 Less time spent managing litterDescriptionbhsl have miniaturised proven power plant technology to provide reliable on-site energy recovery from a variety of low calorifi c value, high moisture biomass such as wet wood chip, poultry litter and spent mushroom compost.Benefi ts9 Energy Security – the energy from poultry litter can meet and exceed the energy demands of poultry production9 The valuable nutrients in the ash have one tenth the volume of litter and are more readily transported to where they are needed9 Incentives for Renewable Energy, such as the RHI in the UK9 Carbon Credits9 Providing other options to landspreading in poultry intense regionsDescriptionOnce a house is cleared of birds the litter is loaded into a biosecure fuel storage and handling system called a Toploader bunker. The air required for Fluidised Bed Combustion is drawn from this storage structure ensuring no leakage of odours or pathogens. Fuel handling is fully automated so farm staff have no further contact with litter after loading it in.Benefi ts9 A unique handling system that enhances the stringent biosecure standards demanded by modern poultry operations9 Low energy – 2 small motors only used intermittently9 Stores all the litter produced on a farm with all moving parts easily accessible for maintenance9 Scalable to meet the specifi c site demandTechnical Specifi cationsUnit Dimensions 12m long x 8m wide x 6m highHeat Output 500 kWthFuel Input (tonnes per day) Wet Wood Chips 7 tpd Poultry Litter 5.5 tpd Spent Mushroom Compost 7.8 tpdParasitic Load 17 kWePatent Numbers S85598, S85574, S85571, S85735, S85573,S85736, S85572
