Retrofitted coal-fired firetube boiler and method employed therewith

Patent Wagoner, C L; Foote, J P

A coal-fired firetube boiler and a method for converting a gas-fired firetube boiler to a coal-fired firetube boiler are disclosed. The converted boiler includes a plurality of combustion zones within the firetube and controlled stoichiometry within the combustion zones. 19 figs.
Super low NO.sub.x, high efficiency, compact firetube boiler

Patent Chojnacki, Dennis A.; Rabovitser, Iosif K.; Knight, Richard A.; ...

A firetube boiler furnace having two combustion sections and an in-line intermediate tubular heat transfer section between the two combustion sections and integral to the pressure vessel. This design provides a staged oxidant combustion apparatus with separate in-line combustion chambers for fuel-rich primary combustion and fuel-lean secondary combustion and sufficient cooling of the combustion products from the primary combustion such that when the secondary combustion oxidant is added in the secondary combustion stage, the NO.sub.x formation is less than 5 ppmv at 3% O.sub.2.

Process to improve boiler operation by supplemental firing with thermally beneficiated low rank coal

Patent Sheldon, Ray W [Huntley, MT]

The invention described is a process for improving the performance of a commercial coal or lignite fired boiler system by supplementing its normal coal supply with a controlled quantity of thermally beneficiated low rank coal, (TBLRC). This supplemental TBLRC can be delivered either to the solid fuel mill (pulverizer) or directly to the coal burner feed pipe. Specific benefits are supplied based on knowledge of equipment types that may be employed on a commercial scale to complete the process. The thermally beneficiated low rank coal can be delivered along with regular coal or intermittently with regular coal as the needsmore » require. « less

Integrated process and apparatus for control of pollutants in coal-fired boilers

Patent Hunt, Terry G [Aurora, CO]; Offen, George R [Woodside, CA]

A method and apparatus for reducing SO.sub.x and NO.sub.x levels in flue gases generated by the combustion of coal in a boiler in which low NO.sub.x burners and air staging ports are utilized to inhibit the amount of NO.sub.x initially produced in the combustion of the coal, a selected concentration of urea is introduced downstream of the combustion zone after the temperature has been reduced to the range of 1300.degree. F. to 2000.degree. F., and a sodium-based reagent is introduced into the flue gas stream after further reducing the temperature of the stream to the range of 200.degree. F. tomore » « less

Apparatus and method of controlling the thermal performance of an oxygen-fired boiler

Patent Levasseur, Armand A.; Kang, Shin G.; Kenney, James R.; ...

Disclosed herein is a method of controlling the operation of an oxy-fired boiler; the method comprising combusting a fuel in a boiler; producing a heat absorption pattern in the boiler; discharging flue gases from the boiler; recycling a portion of the flue gases to the boiler; combining a first oxidant stream with the recycled flue gases to form a combined stream; splitting the combined stream into several fractions; and introducing each fraction of the combined stream to the boiler at different points of entry to the boiler.
