Abstract: PROBLEM TO BE SOLVED: To disclose a method of controlling the air to fuel ratio in a burner containing a venturi assembly.SOLUTION: The venturi includes: an air inlet; a primary fuel inlet with a converging section; a throat portion positioned downstream from the converging section; a diverging section positioned downstream from the throat portion; an outlet; a secondary gas inlet disposed downstream from the converging section and upstream from the outlet; and a tubular portion positioned downstream from the diverging section, wherein the secondary gas inlet is formed in the tubular portion. The method of controlling the air to fuel ratio includes the steps of: introducing fuel into the fuel inlet; receiving air through the air inlet by inspiration; and feeding a gas through the secondary gas inlet, wherein the flow rate and content of the gas fed through the secondary gas inlet are selected to result in a desired air to fuel ratio through the outlet. A method of firing a heater, a burner, a furnace and firing control systems also are disclosed.

Abstract: A furnace, firing pattern and method of operating a heater that employs a combination of hearth burners and wall burners for the cracking of hydrocarbons is described. The firing pattern leads to improvements in the uniformity of the coil metal temperatures and vertical heat flux profiles over the firebox elevation. The hearth burners operate with a stoichiometric excess of air while the wall burners operate with less than the stoichiometric amount of air.

Abstract: A furnace (10), firing pattern and method of operating a heater that employs a combination of hearth burners (46) and wall burners (56) for the cracking of hydrocarbons is described. The firing pattern leads to improvements in the uniformity of the coil metal (26) temperatures and vertical heat flux profiles over the firebox elevation. The hearth burners (46) operate with a stoichiometric excess of air while the wall burners (56) operate with less than the stoichiometric amount of air.
