Blower view for melting furnace burner

I do question the leaf blower only because I have gone through several and they are a cheap motors and found my last 3 unreliable for a good run. The air pressure they give is more than needed so I only hope you have a way to also jack it down via some divergent pass system when needed to do a flame adjustment. I melt way more at a time in a much bigger furnace and use a vacuum cleaner motor for the air. That then goes into a pipe with a large 3 inch diameter water shut off valve before it turns into the 90 degree angle run into the furnace where the gas is also added. That makes it possible to throw away some of the air pressure without taxing the blower motor or chocking the intake and making the blower motor run hotter.
