Abstract In order to study the effect of near-ground explosion energetic materials (EMs) on shell a vertical incinerator, different heights EMs 90 g TNT incinerator with exhaust gas outlet diameters was numerically simulated in three dimensions using AUTODYN software. The simulation results showed that maximum von Mises equivalent stress (mis. stress) occurred at upper edge outlet. Furthermore,...

OBJECTIVES To find whether concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in serum increased in workers at municipal incinerators that burn continuously. METHODS 30 Workers employed at three municipal waste incineration plants (incinerator workers) and 30 control workers were studied. The incinerator workers had worn dust masks or airline...

The increased interest to carry out air quality impact assessment by using sophisticated and state-of-the art air quality modeling systems has conducted us to simulate the air quality impact of a projected incinerator in the Basque Country (North of Spain) area (San Sebastian) as requested by the promoter. In this contribution we show the implementation of a modified version of MM5-CMAQ [3] for...

Calculations of total reactor size have been made for the over bed combustion region of an incinerator, for a given area firing rate, assuming a variation in the completeness of reaction (conversion) "in the stirred section. As conversion increases, the overall reactor size drops to a minimum at 85 percen t con­ version and then rises again. At this minimum, the overbed heigh t required was cal...

This work investigated the characteristics of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) in stack-flue gases from six stationary emission sources in five types of incinerators: industrial waste incinerator (IWI), small-scale municipal solid waste incinerator (MSWI), medical waste incinerator (MWI), cement kilns (CK), and crematories (CR). These characteristics were further inv...

The most commonly used technology for dealing with medical waste, till recently was an incinerator. Incinerator, when introduced was supposed to be a wonder technology. A technology that would get rid of loads of waste by burning it and would leave behind some ash, that could be dumped. However, instead of solving the problem of waste, it aggravated it. It only changed the biological problem in...

There is a widely held belief that fuel bound nitrogen is the principal source of incinerator NOx emissions. This belief leads to the theory that removing high nitrogen com­ ponents like food and yard and garden waste will reduce NOx emissions even though incinerators typically release 75 to 90 percent of the fuel bound nitrogen as diatomic nitrogen gas rather than NOx• This paper explores the ...

The public health aspects of incinerator exhaust gases are discussed first in the light of the physio­ logical response induced by specific contaminants such as sulfur oxides, nitrogen oxides, and other inorganic gases and aldehydes, organic acids, esters, polynu� clear hydrocarbons' , and other organic compounds; second, with respect to their relation to illness caused by air pollution in gene...

OBJECTIVES To find whether or not incinerator workers employed at intermittently burning municipal incineration plants are exposed to high concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). METHODS 20 Workers employed at three municipal waste incineration plants (incinerator workers) and 20 controls were studied. The previous job, dietary, s...

result from other techniques, such as those requiring aeration of cultures. The exhaust air from such operationls must be sterilized and the most reliable means of doing this is incineration. The 1 cfm capacity of the incinerator described above is sufficient for mnost laboratory scale operations. If provision is made for cooling the exit air, the apparatus may be employed as a source of steril...
