The difference is on the order of 9:1. The gas produced later uses the oxygen up and the secondary air is the only supply. It is helpful if the change if air supply is automatic once the pyrolysis reaches the bottom of the charge. </span></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><span style="color: rgb(0, 0, 0); font-family: 'Slate Pro';"><br></span></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><span style="color: rgb(0, 0, 0); font-family: 'Slate Pro';">Regards </span></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><span style="color: rgb(0, 0, 0); font-family: 'Slate Pro';">Crispin </span></div></body></html>
