Atmosphere Protection Through Energy Loss Minimization

摘要

Most of the electrical energy produced all over the world is derived from the fuel comustion process. The process involves an immense atmosphere pollution by waste products from power generation stations, i.e. solid wastes, but predominantly gaseous ones. Combustion gas constituents, i.e. CO sub 2, SO sub 2, and NO sub x are the main energy conversion wasters that pollute the atmospheere. Reduction of that sort of pollution is done based on the tow fundamnetal provisions. The paper emphasizes the fact that non-reversible phenomena result in a loss of the maximal work, especialy of electrical energy, in the process of both gneration and application. To evaluate the loss of work, the concept of evergy si employed in thermodynamics. Exergy is defined as the ighest possible work obtainable form a particular system of bodies in their natural environment. Thus the loss of exergy due to non-reversibility fo phenomena is equivalent to the loss of work. Means of reducing the losses, nd consequently, the pollution level as a method of atmosphere protection, constitute the subject of the paper.
