Abstract

See full text

A pitot tube assembly is provided for a radiant tube heater having a blower for providing combustion air to a burner. The assembly includes a mounting plate for attaching the assembly to a wall of a housing of the blower. First and second, substantially L-shaped pitot tubes extend through the mounting plate and are connected thereto and have respective inner leg sections which are arranged within an outlet section of the blower during use of the radiant tube heater. These leg sections extend in opposite directions to their respective pressure sensing ends. The first pitot tube measures impact pressure created by the blower and the second pitot tube measures static pressure. These tubes are connectible to a differential pressure switch arrangement for controlling operation of the burner. As part of a burner assembly, there is a mixing cup unit mountable within the burner tube of the heater and capable of mixing primary air and combustible gas. A gas valve unit regulates flow of the gas to the cup assembly.
