Abstract
A mixing unit for mixing gaseous fuel and combustion air includes a fuel supply chamber adapted to receive a supply of fuel, an air supply chamber adapted to receive a supply of combustion air, and a manifold separating the air supply chamber and a transfer conduit which is adapted to deliver the fuel-air mixture to a burner. The manifold is formed with air ports establishing communication between the air supply chamber and the transfer conduit such that multiple streams of combustion air flow through the manifold and into the transfer conduit. The manifold is further formed with fuel supply cavities which communicate with the fuel supply chamber and which alternate with the air ports in the manifold. Multiple fuel ports connect each air port with the adjacent cavities such that multiple sets of oppositely directed jets of fuel mix with the combustion air as the combustion air flows through the manifold.
