Abstract
A combustion system includes a combustion fluid charge source and a start-up flame holder configured to attract the charge and hold a flame when the combustion system is cool and allow the flame to lift when the combustion system is warmed up.
Claims45
A combustion system, comprising:
- a charge source configured to apply an electric charge to a combustion fluid;
- a start-up combustion holder configured to attract the electric charge and hold a flame when the combustion system is below a pre-determined temperature threshold and to not hold the flame when the combustion system is above the pre-determined temperature threshold;
- and
- a raised flame holder spaced apart from the start-up combustion holder and configured to hold the combustion reaction when the combustion system is above the pre-determined temperature threshold, wherein the raised flame holder includes a body defining a plurality of perforations extending through the body.
