While the Internet allows instant communication, practical knowledge based on gasification experience is not stored in a data base, then as in my case, it is typed with only one finger. This takes time and I have other things of much greater priority to do. Your urgency is not mine.
It is normal in this forum to at least introduce yourself and status, your location, your project intent, specific physical details of the fuels used (not just their chemical equations out of a book) and some details of how your gasifier is constructed. You will then find that quite a few people will then offer advise and encouragement.
The questions below are unclear to me, but it is obvious that you do not have any understanding of how the gas is made. My advise is to study and develop either wood or coal gasifiers, but not both at the same time as there are big differences in the design requirements. Comments are in the text as best I can offer.
In answer to providing you with solutions to your problems, that is called development work for a gasifier design of reliable performance, and that cost money and time. Between 5-7 years will be about how long that takes to acquire all the knowledge and experience.

What are you asking? You must state wood consumption of any process first to be able to compare savings of higher output efficiencies.

Yes, if working correctly, you increase the blower pressure, but not sure how a damper fits in.

The more pressure, the greater amount of gas made and the faster the wood is consumed. You should get about 2.185m3 of gas for 1kg of wood
Refer to the Wood to Energy Tables located on the Fluidyne Archive www.fluidynenz.250x.com

If you have excess oxygen or air, then you will have more CO2.

No it if just red hot CO2 caused by over pressure, and this has consumed the reduction char that actually makes the gas.
