Radiant heating assembly and method of operating the radiant heating assembly

Abstract

A radiant heating assembly includes a fuel valve, a blower, a controller configured to control the fuel valve and the blower, and a heat exchanger or burner tube having integrated baffle elements. Baffle elements can be integrated externally into the walls of a heat exchanger or burner tube to baffle internally of the heat exchanger.

What is claimed is: 
     
         1 . A radiant heater having an elongated heat exchanger in communication with a burner including baffle elements integrated into the heat exchanger externally of the heat exchanger to provide baffling internal to the heat exchanger. 
     
     
         2 . A system to radiantly heat an area comprising a burner and a burner tube in communication with said burner, further comprising depressions in the wall of said burner tube to form baffles. 
     
     
         3 . A radiant heating assembly comprising:
 a burner for receiving air and fuel for combustion;   an elongated heat exchanger in communication with said burner including baffle elements integrated into the heat exchanger;   a fuel valve for providing the fuel to said burner;   a blower for providing the air to said burner; and   a controller configured to control the amount of the air and the fuel provided to said burner;   
     
     
         4 . An assembly in accordance with  claim 3 , wherein the heat exchanger comprises a U-shaped tube. 
     
     
         5 . An assembly in accordance with  claim 3 , wherein the heat exchanger comprises a single straight tube. 
     
     
         6 . A demand radiant heating system comprising:
 an elongated radiant heating tube having an inlet end and an exhaust end, further comprising depressions in the wall of the heating tube to form baffles internally within the heating tube;   a burner tube connected to said inlet end of said radiant heating tube;   a housing defining an air tight compartment connected to said burner tube,   a blower for continually forcing air into said air tight compartment;   a burner at least partially disposed in said burner tube, said burner having an inlet end to receive air and fuel, means for mixing air and fuel, and an exit end for emitting the air/fuel mixture for combustion closely adjacent thereto; and   single fuel means disposed in said air tight compartment and operatively connected to said inlet end of said burner for providing regulation of fuel to said burner at a plurality of predetermined pressures for demand heating, whereby fuel and air is mixed and burned by said burner to heat said radiant heating tube and exhaust gases exit said exhaust end; and   temperature means connected to said fuel means for triggering said predetermined pressures at a plurality of temperature settings.   
     
     
         7 . A heater comprising: a burner housing having a front panel and an inlet for supplying air into said burner housing; a plurality of burners spaced from each other in said burner housing for combusting a fuel and air mixture into heated gas; a plurality of heater tubes each extending from and returning to said front panel of said burner housing for radiating heat, said heater tubes each having an inlet end and an outlet end with said inlet ends in communication with said burners for receiving the heated gas from said burners and having depressions in the wall of each of said heater tubes to form internal baffles, a collector box disposed in said burner housing in communication with said outlet ends of said heater tubes for receiving the heated gas from said heater tubes; and a fan in communication with said collector box to move the heated gas from said burners to said collector box; said outlet ends of said heater tubes being adjacent each other at said burner housing and each of said inlet ends of said heater tubes being spaced in different directions from said outlet ends at said front panel of said burner housing.
