  • Effect of the radiation heat loss on propagation of the spherical flame through premixed coal dust

    An analytical study has been conducted to investigate the effect of radiation heat loss on the spherical flame propagation in coal–dust clouds. This research can be valuable in the development of alternative fuels; and it can be used by the fire safety and control industry. The model includes the evaporation of the volatile matter of dust particles into a known gaseous fuel (methane) and the ...

  • Carbonization of johkasou sludge using batch-type equipment

    The carbonization of dehydrated johkasou sludge was examined using batch-type equipment. Based on the temperature changes in the carbonization room and the gas combustion room, the carbonization process was divided into three phases: phase I, drying the sludge, phase II, thermal decomposition of the dried sludge, phase III, after phase II. The times required for phases I and II were strongly ...

  • A matter of degrees

    LumaSense Technologies’ E2T product manager, David Ducharme, explains why accurate temperature measurement is critical in a modified Claus sulphur reactor. There are two critical temperatures required for the safe and efficient operation of a sulphur furnace. The first is the refractory temperature, which is critical for hightemperature alarms and automated shutdown systems in the furnace. ...

  • EPA mandatory reporting of GHGs rule

    Recent EPA Guidance EPA does not intend for the calibration requirements of 98.3(i) to apply to any units where the rule allows the use of “company records” to quantify fuel usage or other parameters; however, a facility’s GHG monitoring plan must include descriptions of the procedures and methods used for quality assurance, maintenance, repair of all flow meters ...

  • HClear™ Programs: A Solution-­Based Approach to HCl Abatement

    Fuel Tech recently developed HClear™, an HCl abatement program that relies on the injection of an aqueous solution into combustion gas stream to react with gaseous HCl. This technology involves an aqueous solution that is injected into the flue gas, downstream of the economizer outlet. Upon injection of the aqueous solution into the flue gas stream, a molecular precursor contained within ...

  • SERVOTOUGH SpectraScan 2400 - A tunable filter optical system for on-line and real-time hydrocarbon gas composition analysis

    Abstract An all-optical sensor platform has been developed for hydrocarbon gas composition analysis enabling speciation and quantification of the individual hydrocarbon components in multi-component matrices of alkanes, alkynes, alkenes and/or alcohols. It performs such speciation without requiring physical separation of the compounds as performed in chromatography. The flow-through ...

  • The landfill gas collection, utilisation and surplus gas combustion acting in unison

    In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

  • How to choose detectors in the dangerous cargo warehouse

    The principle of choosing toxic gas and combustible gas detectors in dangerous cargo warehouse: 1.Dangerous cargo warehouse detection of gas mainly including combustible or toxic. Measurement of the type of gas characteristics, the first is to measure the explosion, second is the measurement of toxicity. The so-called measuring explosion is the detection of combustible gases, such as ...

  • Optimizing Catalyst Performance Aids in Lowering Operational & Management Costs

    Catalyst costs can be more than $2 million per layer, and customers are seeking ways to better manage their budget while maintaining catalyst performance. Fuel Tech's TIFI® Targeted In-Furnace Injection™ programs aid in the optimization of catalyst performance by managing slag, fouling, and ABS.  Minimizing the negative impacts of poor combustion while optimizing gas flow paths. ...

  • Exergy analysis of natural gas/DME combustion in homogeneous charge compression ignition engines (HCCI) using zero–dimensional model with detailed chemical kinetics mechanism

    In the present work, a single zone combustion model with detailed chemical kinetics is developed to study the effect of dimethyl ether (DME) concentration on the combustion of natural gas from second law point of view in a homogeneous charge compression ignition (HCCI) engine. The code can predict all exergy terms in the cylinder with crank angle during a closed cycle. The chemical kinetics ...

  • Oxidation System for Sanitary Landfills & Recycling Centers

    A major US waste handling company operates a large landfill in Florida, and in 1992, when Hurricane Andrew struck southern Florida, the landfill saw a huge increase in the amount of C&D waste. Shortly after this, the levels of H2S started dramatically rising. This company evaluated several technologies for the removal of H2S, which was estimated to be as high as 5000 ppmv, with up to 2-3 ...

  • Quick Review Of A Rubber Recycling Plant

    Rubber recycling is the process where waste rubber is changed into useful products, mainly fuel oil. You will discover processing plants around the globe. For example, a rubber recycling plant Asia is actually a one of many recycling facilitates in Southeast Asia. The fact is that there is lots of rubber waste generated around the globe each and every year, and it may have got a damaging effect ...

  • Thermal mass flowmeters fill the bill in precision gas-ratio control application

    Fiberglass insulation manufacturing is almost akin to making cotton candy. A mixture of silica and other components are melted and passed through a spinning extruder, then rapidly cooled with compressed air (see Figure). As older fiberglass manufacturing plants have demonstrated, manual control of air and natural gas flow to the burners used to melt the initial mix often results in unacceptable ...
