Estudo do Controle das Emissões de poluentes em Caldeira Aquatubular de alta pressão com Queimadores Convencionais, Abordagem da Eficiência Versus Custo do Dano.

Abstract

Atmospheric emissions are considered by specialists, government, private organizations and environmental organizations as one of the main causes of all weather changes that our planet has been facing. This work focuses mainly on stationary sources, especially the large ordinary high pressure steam generators. While millions of tons of pollutants are released in the atmosphere by industrial sources annually, human beings are searching for alternative solutions to estabilish clean energy sources. Besides this search, there is growing interest in concentration the generation of emissions on stationary sources, so as to establish an easier way of controlling and treating emissions. A procedure that can be immediately adopted by industries. It has been tested, without the necessity of implementing expensive and time consuming technological changes. Thus, it is possible to immediately reduce the amount of pollutants released in the atmosphere. Besides reducing nitrogen oxides, particulate matter and carbon monoxide, it aimed at reaching a level of them which permitted the establishment of the ideal value between emission and cost of the damage, to obtain the lowest cost of damage. It also presents the methodological base of a model, using Fuzzy logic as a way of obtaining control and reliability on the management of emissions.
