Title	Low NOx Burner for Thermally Enhanced Oil Recovery
Creator	Duret, Michael; Kendall, Robert

Spatial Coverage	presented at Maui, Hawaii
Abstract	Crude oil pumped from California's Central Valley must be heated to reduce its viscosity. The most common production method is thermally enhanced oil recovery (TEOR). In TEOR operations, natural gas-fired steamers force high-pressure steam into production reservoirs where it heats the crude making it easier to pump. By 1996 all steamers must be retrofit with 10w-NOx burners to achieve less than 30 ppm NOx. Alzeta has developed and demonstrated a 10w-NOx burner for oilfield steamers. The burner is a semiradiant, premixed, natural gas-fired burner which uses a patented technique to form radiant and blue flame zones on a porous metal mat. This technique provides heat fluxes that are ten times greater than traditional porous radiant burners. The burner can also destroy large quantities of low-Btu gases containing hydrogen sulfide.

Partial equilibrium NO formation prediction for CH4 -Air flame with 20% excess air 3400 After optimizing the selective perforation in the hot water boiler, Alzeta began work to scale up the burner to the eventual full-scale size of 62.5 million Btu/hr. The full sized burner had to be cylindrical to match the shape of the radiant section of the steamer and fit inside the existing hole in the front wall. It also had to be modular because a single 60-fe element would be too large to be practical. The final design consisted of four 16-fe segments each rated at 16 million Btu/hr. Each segment is nominally 30 inches in diameter and 30 inches in length. Four segments, bolted together internally, are needed to form the full sized burner element as shown in Figure 4. An insulated end cap seals the end of the burner. Depending on the required heat duty, and the desire for uniform heat flux to the radiant coil, additional segments can be added or removed. There is however a maximum length to diameter ratio depending on surface firing rate and acceptable fan delivery pressure.
