Dear Sir,
We have run the gasifier for 6 hours an Aluminum meal melting industry. Blower details are given blower Blower capacity = 500 CFM and pressure = 500mm water column For 300kg /hr wood consumption we have need 450 kg of air is needed. Final outlet gas as 750kg/hr is produced. Air fuel ratio is 1:1.5 In my question is 1. For 300kg /hr wood consumption we have increased the air is 1500 kg/hr. Final outlet gas as 1800 kg/hr is produced. So air fuel ratio is 1:5 We increase the air quantity and also increase the gas production rate. It is directly proportional to air velocity. For complete combustion process = 6.36 kg of air needed For complete GASIFICATION Process we will increase the air at almost 5kg of air is needed. 1 kg of wood + 1.5 kg of air = 2.5 kg of producer gas produced (Thumb Rule) 1 kg of wood + 5 kg of air = 6 kg of producer gas produced (For COMPLETE GASIFICATION PROCESS) Whether this is correct or not? Please explain A. Saravanakumar
