The gas burner assembly includes fuel valve for providing a flow of fuel and an air pump for providing a flow of air into a boost fuel chamber prior to combustion. The method includes obtaining a predetermined cold start airflow schedule and modifying the cold start airflow schedule if the operating history of the gas burner assembly indicates that the temperature of the gas burner assembly is elevated, e.g., not cold. Specifically, the warmer the gas burner assembly, the more the airflow is increased relative to the cold start airflow schedule.

In a method and system for the combustion of ammonia, wherein a first combustion chamber receives ammonia and hydrogen in controlled proportions, and an oxygen-containing gas such as air. Combustion of the ammonia and hydrogen produces nitrogen oxides among other combustion products. A second combustion chamber receives the nitrogen oxides along with further ammonia and hydrogen in further controlled proportions along with further oxygen-containing gas such as air. The nitrogen oxides are combusted into nitrogen and water.

Emissions of mercury, NOx, and/or SOx are reduced by enzyme treating coal before combustion, optionally with further treatment of the coal with certain non-bromine containing powder sorbents. y using the steps together, mercury can be reduced by 40% or more, and NOx by 20% or more. Advantageously, no bromine is introduced with the remediation steps.
