Burner having low pollutant emissions

A burner characterized by low pollutant emissions, the burner comprising:

• an elongated casing having outer and inner shells and including a combustion chamber having upstream, middle and downstream regions, the casing further including a laterally oriented fuel mixture inlet for admitting a combustible mixture of fuel and air laterally into the upstream region to induce turbulence in the mixture as the mixture changes direction to flow downstream, the outer and inner shells being spaced apart to define an annular water jacket having a water inlet in the upstream region and a water outlet in the downstream region, the jacket including water directing means operative to swirl the water through the jacket as it flows downstream, the casing further including igniter means operative to ignite the mixture;
• fuel preheater heat exchange means located in the middle region, and having a fuel inlet line to accept fuel from a fuel source and a fuel outlet line to discharge preheated fuel;
• and
• air intake means including nozzle means for accepting and further accelerating high velocity fuel from the fuel outlet line of the fuel preheater heat exchange means, and including air aspirator means operative to accept the high velocity fuel and aspirate air to form the combustible mixture, and further including conduit means connecting the air intake means to the fuel mixture inlet of the casing.
