Abstract
A radiant heater in which the fuel is supplied at an inlet end of a combustion chamber, formed by an imperforate tubular shell, where combustion takes place, and the products of combustion are forced axially in one direction through the tubular shell, which is elongated to provide a substantial heat radiating wall, and out through an outlet end thereof. Surrounding the first shell, is a second tubular shell, which is concentric with the first shell to provide a second substantial heat radiating wall and an annular chamber which receives the products of combustion from the combustion chamber, directs them axially in a reverse direction, and permits them to discharge outwardly through radial outlets provided in said second radiating wall. Combustion is accomplished by a burner which is located at the inner end of the first shell to cooperate therewith and with the second shell in an effective manner to obtain maximum combustion and radiation.
