The Fisher Burner produces an intensly hot flame for all types of laboratory heating operations including many ignitions and incinerations which otherwise would require the use of compressed air. Instead of the cold cone and hot tip characteristic of the Bunsen flame, the Fisher flame is short and wide and is uniformly hot throughout.

There is a growing concern for adverse effects of untreated discharge from confined animal feedlot operations (CAFOs) in the Midwestern states. Ample data exists to show that the waste discharge from livestock operations is a major contributor to the contamination of surface water systems. The United States Environmental Protection Agency (US EPA) estimates that 41 percent of the total non-poin...

A theoretical–numerical analysis based on the second law of thermodynamics is used to examine the propagation of laminar H2-enriched CH4–air flames. The analysis is based on computing the various entropy generation terms in a transient reacting flow field. A comprehensive, time-dependent computational model, which employs a detailed description of chemistry and transport, is used to simulate th...

In view of improved control of the combustion process in e.g. industrial glass furnaces, accurate in-situ COgas sensors are required. With help of reliable in-situ gas sensors, burner control can be optimised. By better burner control, NOx emissions can be reduced and the radiative heat transfer from combustion chamber to the glass melt and thus the energy efficiency of glass furnaces can be im...

The local air quality districts in the Los Angeles area were the first to implement restrictions to require that NOx emissions on natural gas fired boilers be reduced to single digit levels. Now additional states are being required to develop State Implementation Plans (SIPs) to address bringing into compliance the areas that do not meet the ozone standards set forth in the Clean Air Act Amendm...

To describe the effects of inert compounds in gaseous fuel, experiments on three different process burners (staged fuel burner, staged air and low-calorific burner) were carried out. The tested are commercially available, but they specially designed for experimental usage. Tests out semi-industrial burner testing facility to investigate influence gases flame characteristics, emissions, heat flu...

Commercial vehicles require fast aftertreatment heat-up to move the SCR catalyst into most efficient temperature range meet upcoming NO X regulations while minimizing CO 2 . One solution this challenge is add a fuel burner upstream of con`ventional heavy-duty diesel system. The focus paper optimize based thermal management approach. objective included complying with CARB’s 2027 low emissions st...

Thermal barrier coatings (TBC) on turbine hot section components require regular maintenance by visual inspection for which the engine is taken out of service and partially disassembled. Early detection of the TBC degradation and failure is critical to prevent catastrophic engine failure. Under this project it was proposed to incorporate Li2O as a maker material in the TBC away from the surface...
