ABSTRACT:
An advanced compact heater which includes a radiant section of tube coils nested about a plurality of tiers of vertically spaced-apart fiber matrix burners. Each burner is comprised of a hollow cylindrical shell of a fiber matrix material with an oval cross-section of optimum height-to-width aspect ratio and a long length-to-height aspect ratio. A process fluid or water is directed through the radiant coil of tubes disposed in vertical arrays on opposite sides of the burner tiers. Pre-mixed fuel and air flamelessly combusts on the active sections of the burner surfaces permitting narrow burner-to-coil spacing with a compact heater size and reduced capital cost in relation to the heat input rating. Exhaust from the burners flows in heat exchange relationship past tube coils in a convective section for extraction of residual heat.
