Abstract
A hollow ceramic fiber wick is used for combustion of diesel or other liquid fuels in a small combustor. Fuel and air are provided to the hollow ceramic wick by a positive-displacement fuel pump and a positive-displacement air blower driven by a common microprocessor-controlled driveshaft. A first portion of the air is provided directly to the wick while a second portion of the air is communicated by passageways outwardly concentric from the wick holder to a swirler chamber near the tip of the wick within the combustion chamber.
