A burner assembly including a housing and an airflow restrictor plate for selectively restricting an amount of airflow passing out of the housing in order to reduce a heat output of the burner assembly. The housing has an air inlet and an air outlet and is configured to guide an airflow from the air inlet and out of the housing via the air outlet. The airflow restrictor plate has a single opening through which all airflow flowing through the housing from the air inlet must pass in order to exit the housing via the air outlet.

Modular fuel burner assembly

A mixing tube assembly having an inlet end and an outlet end and being adapted for use in a burner assembly. The mixing tube assembly comprises a substantially cylindrical outer wall which defines an interior open space. The mixing tube assembly also comprises a turbulator that is disposed in the interior open space defined by the substantially cylindrical outer wall and a flow straightening device that is disposed downstream from the turbulator. A method for mixing fuel and air in a burner assembly comprising providing a mixing tube assembly. The preferred method also comprises conveying fuel and air from the inlet end of the mixing tube assembly to the outlet end of the mixing tube assembly and straightening the gaseous fuel and air mixture flow in the mixing tube assembly.
