Flameless Candle with Multimedia Capabilities

The Journal of the Acoustical Society of America, 2012
A flameless candle having speaker and lighting capability is provided. Multiple of such flameless candles can be used in a system to generate stereo or surround sound, as well as various lighting modes. The flameless candle or flameless candle system can have AM/FM radio functions, clock functions, alarm functions, etc., and can be used as an audio ...

Ammonia chemistry in a flameless jet

Combustion and Flame, 2009
Abstract In this paper, the nitrogen chemistry in an ammonia (NH 3 ) doped flameless jet is investigated using a kinetic reactor network model. The reactor network model is used to explain the main differences in ammonia chemistry for methane (CH 4 ) containing fuels and methane-free fuels. The chemical pathways of nitrogen oxides (NO x ) formation

Trace analysis by flameless atomic-absorption spectrometry

Talanta, 1972
The operating conditions of an atomic-absorption system based on flameless atomization have been investigated for trace analysis for Al, Cr, Cu, Fe, Mg and Mn. The sample solution on a tantalum strip was atomized by electrical heating in an inert atmosphere within an absorption chamber. This technique allows the use of small sample sizes and results in

Copper in erythrocytes by flameless atomic absorption spectroscopy

Biochemical Medicine, 1975
Abstract This study describes a method of analysis for copper in red blood cells. The sample is digested with nitric acid in a Teflon-lined steel bomb. It then is diluted and run without any further treatment. A small hole is drilled into the inner surface of the carbon tube to eliminate irreproducible sample spreading and subsequent irreproducible ...

Determination of zinc by flameless atomic absorption spectrophotometry

Analytical Biochemistry, 1973
Abstract The flameless atomic absorption method described here is a simple, rapid, accurate microtechnique for determining zinc in aqueous solutions, serum, or urine. It requires no sample pretreatment, only 1.0 μl of sample per determination, no correction for viscosity differences between sample and standard solutions, and is not subject to ionic ...

Experimental evaluation of the performance of a flameless combustor

Applied Thermal Engineering, 2013
Abstract The aim of this study was to investigate experimentally the flameless oxidation phenomena. Experiments have been performed in a small-scale combustor fired with methane, and include detailed measurements of local mean temperatures and concentrations of major gas species for four representative combustor operating conditions, and flue-gas ...

CFD Analysis of the Flameless Combustion in a Micro-Gas Turbine

Volume 4: Cycle Innovations; Industrial and Cogeneration; Manufacturing Materials and Metallurgy; Marine, 2009
The concept of flameless combustion as an effective tool for reducing the nitric oxide emission from micro-gas turbines is worthy of an accurate investigation of the thermo-chemical processes inside the combustor. To this aim the authors, basing on their previous experiences on this subject, present a more detailed analysis of the combustion phenomena ...

THEORETICAL AND NUMERICAL INVESTIGATION ON FLAMELESS COMBUSTION

Combustion Science and Technology, 2002
Abstract Flameless combustion has been acknowledged as one of the most interesting combustion technologies to meet both the targets of high process efficiency and low pollutant emissions. A theoretical and numerical investigation, carried out to provide a consistent physico-chemical explanation of this combustion regime, is reported here.

Flameless Atomic Absorption Spectroscopy of Plasma Chromium

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1980
A flameless atomic absorption spectroscopy method has been developed for the measurement of chromium. Background correction has been modified by recording non-atomic absorption separately from atomic absorption on a double-pen recorder. This was achieved by using the prime spectral line of uranium (358·5 nm, within 0·6 nm of that of chromium—357·9 nm)

Flameless technology for particulate emissions suppression

2009
Combustion is a great source of carbonaceous and inorganic particle emissions, even though the combustion technologies and their efficiency are improving. Flameless oxy-combustion technology provides frontier emission performances, with the most advanced Rankine+Joule Bryton high yield thermodynamic cycle.
