“…They found that the optimal N-agent injection point with stoichiometric ratio of 0.99 was needed. Zamansky (1997) and Zamansky and Rusli (1999) found that sodium salt promoters could greatly improve the AR performance. Tree and Clark (2000) studied the detailed species profile of the reaction zone.…”

“…Both of these two characteristics can improve or expand the SNCR process temperature window. Overall NO reduction of 85% was obtained in a down-fired furnace by Hampartsoumian and Folayan (2003), 84% by AR-lean and 93% by AR-rich was achieved in a Boiler Simulator Facility (BSF) by Energy and Environmental Research Corporation (EER, USA) (Zamansky, 1997).…”

Pulverized coal reburning, ammonia injection and advanced reburning in a pilot scale drop tube furnace were investigated. Premix of petroleum gas, air and NH 3 were burned in a porous gas burner to generate the needed flue gas. Four kinds of pulverized coal were fed as reburning fuel at constant rate of 1g/min. The coal reburning process parameters including 15%~25% reburn heat input, temperature range from 1100 °C to 1400 °C and also the carbon in fly ash, coal fineness, reburn zone stoichiometric ratio, etc. were investigated. On the condition of 25% reburn heat input, maximum of 47% NO reduction with Yanzhou coal was obtained by pure coal reburning. Optimal temperature for reburning is about 1300 °C and fuel-rich stoichiometric ratio is essential; coal fineness can slightly enhance the reburning ability. The temperature window for ammonia injection is about 700 °C~1100 °C. CO can improve the NH 3 ability at lower temperature. During advanced reburning, 72.9% NO reduction was measured. To achieve more than 70% NO reduction, Selective Non-catalytic NO x Reduction (SNCR) should need NH 3 /NO stoichiometric ratio larger than 5, while advanced reburning only uses common dose of ammonia as in conventional SNCR technology. Mechanism study shows the oxidization of CO can improve the decomposition of H 2 O, which will rich the radical pools igniting the whole reactions at lower temperatures.

“…Tests conducted in 300 kW and 20 kW pilot-scale facilities [2] demonstrated that efficiency of NO x reduction in Advanced Reburning (AR) could be up to 95% if parameters of AR were optimized. Tests in 3 MW Tower Furnace [3] confirmed that overall NO x reduction in AR can be up to 96%.…”
