Proof of concept testing of an integrated dry injection system for SO/sub x//NO/sub x/ control: Quarterly progress report, January--March 1989
The team of Cottrell Environment Sciences, KVB and Riley Stoker will conduct a proof a concept demonstration of an Integrated Dry Injection Process. The process consists of combustion modification using low NO/sub x/ burners to reduce NO/sub x/ (i.e., NO + NO/sub 2/) emissions, dry injection of hydrated lime at economizer temperatures for primary capture of SO/sub 2/, and addition of a commercial grade sodium bicarbonate at the air heater exit for additional SO/sub 2/ and NO/sub x/ removal. This concept is illustrated.The process offers the potential for simultaneously achieving 90+% SO/sub 2/ removal, and 75+% NO/sub x/ removal from a high sulfur flue gas, and is well suited for new or retrofit applications since it can be incorporated within the existing economizer and downstream duct. Capital costs are kept to a minimum since no large system components such as catalytic beds, spray dryers or scrubbers are required. The proof of concept demonstration will be conducted in the large combustor at the Riley Stoker research facility in Worcester, MA. 8 figs., 1 tab.
