In this study, the ultra-low NOx emission of anthracite was achieved by preheated combustion technology. Meanwhile, model established using Aspen Plus. High-temperature preheating (above 950°C) improved conversion process from fuel-nitrogen to N2 and precursor NOx, which involved cracking N-5 N-6. The rate 81.88%. addition, heterogeneous reduction reaction critical path for during combustion. 0.43%. average tail flue gas 40.77 mg/m3 46.15 (@6%O2) Jincheng Yangquan anthracite, respectively....
With the continuous growth of renewable energy, electricity market is increasingly targeting flexibility and deep-peaking capabilities for coal-fired generation. In this study, low-load operation rapidly load-change characteristics pulverized coal combustion are explored on a 1 MW th test platform, based promising preheating-combustion technology. At loads 25% 35%, great gas–solid flow stable operating parameters such as temperature pressure drop can be achieved in pre-circulating fluidized...
In this study, the operating characteristics and NOx emission patterns are explored under a wide load range based on 2MWth pulverized coal preheated combustion test platform. Preheated char with high physical sensible heat gas calorific value greatly improve ignition stability of at low loads. Moreover, performing pre-denitrification during preheating process helps to lower emissions. Stable operation 26%-106% was achieved, ultralow loads 40% 26% were achieved when pre-circulating fluidized...
In this study, the anthracite was preheated by a circulating fluidized bed under O2/N2, O2/CO2 and O2/CO2/H2O atmospheres. And preheating characteristics of were studied, including conversion law main components variation particle structure. The gasification reactivity relatively weak, carbon approximately 20% Compared with O2/N2 atmosphere, structure improved more obviously atmosphere when oxygen concentration 31%, which mainly reflected in increase BET surface small aromatic rings....
The conversion characteristics of anthracite and bituminous coal were studied under preheating by a circulating fluidized bed deep gasification technology, revealing the paths preheated fuel gasified fuel. operating temperature volatile content determined raw coal. Compared with coal, reactivity was lower, which reflected in higher ratios main components for during preheating-gasification. However, increased after anthracite. factors enhanced included an increase BET surface area, expansion...
