摘要:

Experiments, under controlled conditions, were conducted on the coinbustion of wood waste to establish the effects of process variables on the emission of air pollutants. Temperature in the combustion zone was found to be the most important parameter affecting the combustion process and associated air pollutants. The amounts of air pollutants were minimal at combustion zone temperatures greater than 1100 °F. The hydrocarbons present in aerosol form in the exhaust gases were identified as abiatic acid and stearic acid. The gaseous hydrocarbon in the exhaust gases was mostly methane.

摘要:

This paper presents the results of calorimetrically measured energy feedback from steady-state diffusion flames above a small water-cooled burner transpiring from its top surface a uniform flux of ethane, propane, or carbon monoxide, both pure and diluted with inert gases. The burner was operated in a small low-speed tunnel in which the “ambient” nitrogen/oxygen volume ratio was varied from 3.17 to 4.56. The experiments involved independent variation of the parameterb, a dimensionless heat of reaction per unit stoichiometric mixture of burner gas and ambient gas.

摘要:

The effect of 0.06% by volume of the additive, 2-Methylcyclopentadienyl manganese tricarbonyl (Ethyl Corporation Combustion Improver No. 2), on particulate and gaseous emissions from a model gas turbine combustor was measured. The additive increased the total mass of particulate emissions in these combustor experiments, probably by adding manganese oxides to the exhaust. Without the additive, the smallest of the carbonaceous exhaust particles were typically 0 (0.1 μ) in diameter. These particles agglomerate into “popcornlike” structures of 0 (1μ) and thus are efficient scatterers of visible radiation. With the additive, exhaust particles, composed of manganese oxides and carbon, are 0 (0.05 μ) with significant reduction in agglomeration. No effect on gaseous NO emissions and a negligible decrease in gaseous CO emissions was noted.

摘要:

A theoretical model of nitric oxide formation in single fuel droplet combustion is developed which describes the formation of nitric oxide in the vicinity of a flame front and the diffusion and radial convection of nitric oxide away from the region of formation. Integral equation methods are used to solve for nitric oxide concentration as a function of time and radial distance from the moving boundary of the droplet. Results of calculations using the model to solve for the extent of nitric oxide formation in ethanol droplet combustion are presented. The effects of droplet size, air temperature, and pressure on nitric oxide production are illustrated.

摘要:

The low temperature slow combustion of acetone has been investigated, in a static system, particular attention being paid to the relationship between slow combustion and cool flames. Self-heating occurred, temperature rises of about 10°C at the centre of the reactor being observed in the slow reaction below the cool flame limit. Much larger temperature rises were observed in the cool flames.
