Abstract

A combustor apparatus and method for the combustion of viscous fuels are provided. The combustor apparatus can include a precombustion chamber particularly adapted to heat and at least partially combust a heavy primary fuel, and a main combustion chamber adapted to combust the primary fuel uniformly through the main combustion chamber (in flameless mode). The precombustion chamber can include at least one air injection inlet port positioned to induce a first stage vortex in the main body portion of the housing of the precombustion chamber. Further, the precombustion chamber can be interfaced with a main combustion chamber to induce a second stage vortex within the main combustion chamber. The main combustion chamber can have an extended axial length in order to accommodate heavier fuels that require additional time to sufficiently combust (oxidize) within the combustion chamber.
