FIELD: energy.
SUBSTANCE: invention relates to the field of energy. The burner assembly comprises a housing having an air intake and an air outlet and configured to direct the air flow from the air intake to the housing outlet through the air outlet, and an airflow restriction plate for selectively limiting the amount of air flow exiting the housing in order to control the heat output of the burner assembly wherein the airflow restriction plate has a single opening through which all air flow passing through the housing from the air inlet must pass to exit the housing through the air outlet, the airflow restriction plate being selectively extractable from the housing. The airflow restrictor plate opening is substantially located in the center of the housing when the airflow restrictor is mounted on the housing, and is configured to redirect a portion of the airflow from the surface of the inner wall of the housing to its center, and then through the opening in the airflow restrictor plate to exit through the air outlet.
EFFECT: invention makes it possible to increase and decrease the heat output of the burner.
