Cooking can however be started sooner than when using a BLUD ignition. After the coal is coked, people take the burning device inside their homes. At that stage it produces nearly no PM at all – extremely low – but quite a lot of CO. The CO level varies greatly based on how the holes are patterned.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards<o:p></o:p></p><p class=MsoNormal>Crispin<o:p></o:p></p></div></body></html>
