Abstract
A combustion system such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
Claims85
A burner system, comprising:
- a fuel and oxidant source disposed to output fuel and oxidant into a combustion volume to form a fuel and oxidant mixture;
- and
- a perforated reaction holder disposed in the combustion volume, the perforated reaction holder including a perforated reaction holder body defining a plurality of perforations aligned to receive the fuel and oxidant mixture from the fuel and oxidant source;
- wherein the perforations are configured to collectively hold a combustion reaction supported by the fuel and oxidant mixture.

A furnace, comprising:
- a fuel and air source disposed to output fuel and air into a combustion volume to form a fuel and air mixture;
- a perforated reaction holder disposed in the combustion volume, the perforated reaction holder including a perforated reaction holder body defining a plurality of perforations aligned to receive the fuel and air mixture from the fuel and air source;
- and
- a perforated reaction holder support structure configured to support the perforated reaction holder at a distance DD from the fuel and air source.

A combustion system, comprising:
- a fuel and oxidant source configured to output fuel and oxidant as a fuel and oxidant mixture;
- a perforated reaction holder aligned to receive the fuel and oxidant mixture across an input surface including a plurality of perforations;
- and
- a heating apparatus configured to cause heating of the perforated reaction holder;
- and
- a control circuit operatively coupled to the heating apparatus, the control circuit being configured to cause the heating apparatus to operate;
- wherein the control circuit is configured to support a combustion reaction supported by the fuel and oxidant mixture in the plurality of perforations after the heating apparatus preheats the perforated reaction holder.
