Question

Answer 1

Use DRY wood, it smokes little, it is the sap in wood that makes the smoke, noticed the ?? in old movies sending smoke signals, they threw green branches on the fire to make the smoke.

Answer 2

Go to a home improvement store like Home Depot and get a replacement burner for a propane barbeque. It has a air venturi that produces blue smokeless flames. Put  the burner unit in the fire pit and use a propane tank away from the burner by using a longer hose so the propane tank doesn't get hot.  If you want to keep it super cheap, use charcoal briquets.
