Abstract: Embodiments disclosed herein are directed to combustion systems that include a mechanism or device for reducing combustion temperature. For example, in an embodiment, a combustion system may include a flame control assembly that may draw combusted fuel (e.g., flame produced during combustion) toward a structure that may absorb heat therefrom, thereby reducing combustion temperature.
