<p>The present invention is a dry ash handling system which creates a vertical ash pile in an ash hopper that allows continued combustion of unburned embers. The ash height allows embers to be completely burned before leaving the bottom of the hopper. The hopper includes an air layer injection system which forces air up through the hot ash from below the top of the ash pile, increasing burn-out efficiency. The air rising through the hot ash returns residual heat to the combustion process increasing combustion efficiency, while cooling the ash to a safe handling temperature. The air capturing the residual heat is replaced with cool fresh air, enhancing cooling and preventing dust from escaping. The sides of the hopper are sloped causing the ash to be mixed as it travels to the bottom, preventing air channels from forming.</p> |
