The axial forces on the particles are reduced upon increasing particle density and size, leading to particle accumulation in the dense-phase zone. When the particle properties are stable, increasing the fluidizing gas flow rates by the same proportion leads to identical pressure drops on the involved two loop seals, which cause symmetrical alterations in the particle circulation rate between the air and fuel reactors.

Specifically, we examine the flames diluted by N<sub>2</sub> and H<sub>2</sub>O, respectively, analyzing the flame structure, heat release rate, temperature, main species concentrations, and NO<em><sub>x</sub></em> emissions. The fictitious gaseous diluents of FH<sub>2</sub>O and FN<sub>2</sub> are applied to quantitatively distinguish physical and chemical effects. Results show that the chemical effect of dilution by N<sub>2</sub> is negligible while both physical and chemical effects by H<sub>2</sub>O dilution significantly increase the flame thickness and hence reduce the heat release rate and temperature. Furthermore, both effects of H<sub>2</sub>O dilution diminish as the burning regime transitions from MILD to traditional or high-temperature combustion. In particular, the H<sub>2</sub>O dilution physically reduces the concentrations of the main species. On the other hand, the chemical effect raises the concentrations of H<sub>2</sub>, OH, and NO in the traditional and high-temperature combustion, contrasting to that under the MILD regime. As for NO<em><sub>x</sub></em> emissions, the H<sub>2</sub>O dilution reduces NO emission in the MILD and high-temperature combustion but influences negligibly in traditional combustion. Additionally, the chemical effect of H<sub>2</sub>O shows a contrasting influence on the NO emission under the MILD and high-temperature regimes. Comprehensive explanations are provided for the observed phenomena, shedding light on the intricate interplay of dilution and combustion.</p></div>","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"7 4","pages":"Article 100229"},"PeriodicalIF":6.0,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588913324000188/pdfft?md5=81d79e121e780da14caf3a738fdfa741&pid=1-s2.0-S2588913324000188-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139878558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
