Poultry manure is an abundant fuel that can be combusted in an IED compliant system. Typically, the litter is removed from the chicken sheds at the end of each growing cycle of approximately 7 crops per year.
The manure is delivered to the fuel store where a feed system transports the manure under negative pressure to a conveyor for delivery to the combustor auger feed system. The auger moves the manure (fuel) into the primary combustion chamber for the complete combustion the process to begin.
The combustion gas at around 900°c is diluted through a series of filters delivering 530°c gas to the Organic Rankine Cycle Evaporator.
The heat extracted from the filtered combustion gas converts the ORC working fluid from a liquid to a gas, this change in state spins a turbine which is linked to an electrical generator. The working fluid is then cooled and the resulting heat can be used in a downstream heating process such as poultry sheds, dryer, offices and homes.
The working fluid is then pumped back to the heat source and the cycle repeats.
