The Multi-Fuel Vortex Combustion Chamber
The MFVCC consists of two chambers, the upper pre-burner section and the lower chamber, referred to as the main burner chamber. Fuel is introduced into a perforated dome called the pre-combustion chamber which is used for forming a super-rich fuel and air mixture, ignition, and partial combustion. This chamber is also responsible for transforming low-grade and heavy fuels through a process called gasification.
From the pre-combustion chamber the fuel flows into the main burner compartment. The vortex combustion chamber keeps the particles of liquid fuel within the combustion zone for a sufficient time for complete oxidation of the fuel. Vortex flow is generated by the tangential injection of the air through vanes in the peripheral chamber walls. In the combustion process, a small portion of fuel moistens the inner walls of the liner in each combustion chamber. This unused fuel is then aggregated by a collection system on the inward side of the chambers and recycled back into the combustion process.
The combination of the structural and operational features that the Vortex Combustion Chamber offers, in addition to the fuel collection system, substantially eliminates any unburned emissions. This process also allows for improved completeness of combustion for any liquid fuel having BTU content. This step-wise method of combustion transforms the fuel from the initial super-rich state in the pre-chamber to a super-lean mixture in the vortex chamber. This multistep process assures an over-all low-temperature reaction while the lowering NOx content in the exhaust gases.
