Abstract
A burner assembly for a radiant tube heater having an air duct portion for passage of combustion air to a radiant tube portion includes a mixing cup for mixing combustible gas and air and delivering the mixture to the tube. This cup has an inlet portion and a larger cylindrical outlet portion. Air inlet holes are formed in an upstream end wall of the outlet portion and air ports are formed in a peripheral wall of the inlet portion. An air diverter mounted at an upstream end of the inlet portion has a set of blade which divert a portion of the air through the ports for initial mixing with the gas while a second portion of the air flows through the inlet holes providing additional primary air for mixing. An airflow restricting plate can be mounted on the cup so as to extend circumferentially around the cup.
