Birds heater adaptation and performance using biogas as fuel

It was carried out a trial to evaluate the adaptation (injector diameter) and performance (biogas consumption and heating efficiency) of a heating adapted to burn biogas. It was tried a common heater, burning liquefied petroleum gas (LPG), operating with low gas pressure (28 cm water column), with calorific capacity of 5024 kJ/h and recommended for 500 birds. The heater was evaluated with the original fuel (LPG) without any modification in the gas injector and after adapting to biogas burning. Five injectors were evaluated with drillings of 1,0053; 1,5080; 1,5708; 1,7672 and 1,980 mm2. It also was varied the biogas pressures in the heater entrance of 10, 12, 15, 17 and 20 cm of water column. Results showed that expressions for theoretical calculation and proposed parameters in the literature can be used for aviaries heaters adaptation. The adaptation is simple, indicating the viability for utilization of existing heaters in farms and in the market. Air temperatures were similar to the obtained with the original fuel (LPG).
