Abstract
A fired heater has two cells segregated by an insulative wall. A first plurality of burners are located in the first cell and a second plurality of burners are located in the second cell. A radiant tube extends from the first cell to the second cell for carrying a fluid material through the heater to heat the fluid material. The flow of fuel to the burners in either the first cell or the second cell can be terminated to accommodate lower heater duty when demand is lower.
Claims14
A fired heater comprising:
- a plurality of walls and a floor;
- an insulative wall in a radiant section, said insulative wall separating a first cell of said radiant section from a second cell from said radiant section;
- a first plurality of burners in said first cell and a second plurality of burners in said second cell;
- a radiant tube extending from said first cell to said second cell for carrying a fluid material through said heater to heat said fluid material;
- and,
- a convection section disposed on top of the radiant section such that flue gases from the first plurality of burners and flue gases from the second plurality of burners flow upwards from the radiant section to the convection section, wherein the convection section comprises a convection tube for carrying a fluid material through said heater to heat said fluid material.
