Scientific Essay from the year 2022 in the subject Engineering - Industrial Engineering and Management, grade: A+, , course: M.Sc. (Environmental Studies and Resource Management), language: English, abstract: It is now a well-established fact that air pollution has worsened over the years and the major credit goes to industrial growth. The boilers and stoves are one of the major sources of air pollution from the industries. Therefore, controlling their emissions to a significant extent can lead to the reduction of air pollution. The greenhouse gases of family NOx are important pollutants to be considered in this regard. As per the study by CPCB (2011), in Delhi, industry power plants contribute to approximately 65% of total NOx emissions. Therefore, control of this pollutant may not only lead to the air quality improvement in terms of NOx pollution but will also be beneficial to the environment as NOx cause many ecotoxic effects such as acid rain, eutrophication, ozone formation etc. There are various emission control technologies available for NOx emissions, which can be categorized into two parts-Combustion Control and Post-combustion technologies in the particular context of boilers. Post-combustion methods are mostly expensive as compared to the combustion control methods and are usually not deployed for boilers having input less than 100 MM Btu/hr. So, the focus should be more on combustion control rather than post-combustion treatment. One such powerful method of combustion control is named Flue Gas Recirculation (FGR) which causes a significant reduction in NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. The essay discusses details of the different aspects of this technology.

Maximize efficiency and minimize pollution: the breakthrough technology of high temperature air combustion (HiTAC) holds the potential to overcome the limitations of conventional combustion and allow engineers to finally meet this long-standing imperative. Research has shown that HiTAC technology can provide simultaneous reduction of CO2 and nitric

Fundamentals and Technology of Combustion contains brief descriptions of combustion fundamental processes, followed by an extensive survey of the combustion research technology. It also includes mathematical combustion modeling of the processes covering mainly premixed and diffusion flames, where many chemical and physical processes compete in complex ways, for both laminar and turbulent flows. The combustion chemistry models that validate experimental data for different fuels are sufficiently accurate to allow confident predictions of the flame characteristics. This illustrates a unique bridge between combustion fundamentals and combustion technology, which provides a valuable technical reference for many engineers and scientists. Moreover, the book gives the reader sufficient background of basic engineering sciences such as chemistry, thermodynamics, heat transfer and fluid mechanics. The combustion research and mathematical models fit between small-scale laboratory burner flames, and large-scale industrial boilers, furnaces and combustion chambers. The materials have been collected from previous relevant research and some selected papers of the authors and co-workers, which have been presented mainly in different refereed journals, international conferences and symposia, thus providing a comprehensive collection. Furthermore, the book includes some of the many recent general correlations for the characteristics of laminar, turbulent, premixed and diffusion flames in an easily usable form. The authors believe that further progress in optimizing combustion performance and reducing polluting emissions can only be treated through understanding of combustion chemistry.
