  • Operating Principle of an Oxygen Monitor

    The oxygen concentration in the flue gas of a combustion process such as that of a power plant or a waste incinerator gives a good indication of the efficiency of the combustion process. The parameter is therefore of great interest to optimize fuel economy, but also to control and reduce emissions of air pollutants. An ideal combustion process only results in CO2 and water, but ...

  • Combustion optimization by fast excess air control – Case Study

    Combustion is the conversion of primary chemical energy contained in fuels into heat through the process of oxidation at high temperatures. The oxygen required for the combustion is supplied as part of the combustion air that is fed to the process. In ideal (stoichiometric) combustion the amount of oxygen supplied to the process is just sufficient to burn all combustibles completely. In real ...

  • A process for synthesising polymeric ferric sulphate using sulphur dioxide from coal combustion

    We propose a process that uses sulphur dioxide from coal combustion as a raw material to synthesise polymeric ferric sulphate (PFS), a water treatment agent. The process uses sodium chlorate as an oxidant and ferrous sulphate as an absorbent. Sodium carbonate is used as the regulator of the polymerisation process. The major chemical mechanisms in this reaction system include oxidation, ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • FTIR gas analyzer supports carbon capture research - Case study

    The development of carbon capture and storage (CCS) technologies relies on the accurate measurement of carbon dioxide (CO2) in addition to a wide array of other gases because it is vitally important that the process does not impact upon the emissions of other greenhouse gases and potential pollutants. An advanced FTIR multiparameter gas analyser from Gasmet Technologies is therefore being ...

  • Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

    ABSTRACT Environmental Regulations driven by the 1990 Clean Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas. which ideally reacts with the NOx to form H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...

  • Cost-Effective NOx Control for Air-Preheated Systems

    New advancements in combustion control technologies, such as flue gas recirculation (FGR) and low NOx burners (LNB), have made it possible to achieve ultra low NOx levels without using expensive post-combustion flue gas clean-up technology. For some natural draft units it may be possible to meet the most stringent of the NOx regulations with cost-effective combustion control technologies. For ...

  • The Other Side of Zirconium Oxide case study

    Regular Fuel Efficiency Applications Separate Oxygen and Combustibles Sensors In standard flue gas applications for Thermox analyzers, the user generally tries to extract the maximum energy from the fuel and transfers as much of that energy as possible to the process. These applications require the process to be operated as efficiently as possible by keeping both oxygen (excess air) and ...

  • Science in Aid of Cleaner Air

    Some 60 million tons per year of nitric oxides are released worldwide to the environment as the consequence of human energy consumption. Efficient technologies have been developed to treat flue gas, and Sulzer with some 50 plants is the technology leader. A recent example is AES Cayuga, a coal-fired power plant in Lansing, NY (USA). The combustion of fossil fuels is often conducted at highest ...
