Smoke mix production

Red Phosphorus smoke mix production. Evaluation of the Sprout Waldron 35 cubic foot Jet Airmix unit for production of Red Phosphorus (RP) M8E1 Smoke Mixtures was conducted (12). Results indicated the mix was stabile and not easily initiated by heat, but sensitive to friction and snark stimuli. The burning time was slow with dense smoke emission.

Smoke — the products of incomplete combustion of organic. substances in the form of solid and liquid panicles suspended in air and gaseous products mixed with air. It is visible and generally obscures vision. 

The government owned plants were Firelands, San Bernadino, Turlock, Zanesville, Birmingham Smoke Mix, Birmingham Smoke Pot, Midland, Lake Ontario Ordnance, Niagara Falls, and Duck River. The CWS sponsored plants were operated by Lempco Products Co., Bell Aircraft Ordnance Division, Bell Madiine, Ferro Enamel Corp., and Rheem Manufacturing Co. 

The cadmium chalcogenide semiconductors (qv) have found numerous appHcations ranging from rectifiers to photoconductive detectors in smoke alarms. Many Cd compounds, eg, sulfide, tungstate, selenide, teUuride, and oxide, are used as phosphors in luminescent screens and scintiUation counters. Glass colored with cadmium sulfoselenides is used as a color filter in spectroscopy and has recently attracted attention as a third-order, nonlinear optical switching material (see Nonlinear optical materials). DiaLkylcadmium compounds are polymerization catalysts for production of poly(vinyl chloride) (PVC), poly(vinyl acetate) (PVA), and poly(methyl methacrylate) (PMMA). Mixed with TiCl, they catalyze the polymerization of ethylene and propylene. 

The gases also have other constituents mixed with them, typical ones being dusts, pollens, bacteria, viruses, mold spores, smoke particles, and the products of industrial activity such as SO2, H2, and S. Volcanic activity also adds various gases and dusts to the atmosphere. 

Hydrogen cyanide (HCN) is a colorless, highly poisonous gas or liquid (below 26.7 °C) having an odor of bitter almonds (Hartung 1994 Pesce 1994). It is a weak acid. Exposures may occur in industrial situations as well as from cigarette smoke and combustion products and from naturally occurring cyanide compounds in foods. There is a potential for exposure when any acid is mixed with a cyanide salt. Intravenously administered sodium nitroprusside (Na2[Fe(CN)5N0]-2H20) has been used clinically to lower blood pressure (Schulz et al. 1982). Chemical and physical properties are listed in Table 5-2. 

Measurements showed that the amount of soot produced by the flame was affected by the mixing process between the air jet vortices, the fuel jets, and naturally entrained external air. PIV and smoke flow visualization showed that the air vortices induced strong external air entrainment into the main jet flow very close to the exit plane when the phase angle between the fuel jets and air jet were at the value for minimized soot production. When the wrong phase angle was used, i.e., that which leads to soot formation, the air vorticity coherence was reduced, the vortices appeared to develop further downstream, and the air entrainment at the flame base was significantly reduced. 

When a fuel-rich pyrolant burns in the atmosphere, oxygen molecules from the atmosphere diffuse into the initial combustion products of the pyrolant. The combustion products burn further and generate heat, light, and/or smoke in the atmosphere. A typical example is the combustion process in ducted rockets fuel-rich products generated in a gas generator are burnt completely in a combustion chamber after mixing with air pressurized by a shock wave that is taken in from the atmosphere.
