一、烧结废气为了检验减少废气的可能性,需要了解废气的产生。因此首先要研究废气的来源和成分,并确定操作方式对废气量的影响。下面讨论烧结废气的来源。 1.理论空气需要量在烧结过程中,实际上只是由贯穿流过的空气进行传热。在短暂的烧结时间内,烧结混合料中的热传导和热辐射的分量是很小的。点火时,最上层的烧结料被热的燃烧气体加热,达到燃料点燃温度后,便在高温下进行烧结。通过点火炉后,最上层的温度因吸入冷空气而迅速降低,而吸入的空气则被加热。在燃烧带,固体料和空气都达到烧结 First, the sintering of exhaust gas In order to test the possibility of reducing emissions, need to understand the exhaust gas generation. Therefore, we must first study the source and composition of the exhaust gas, and determine the mode of operation of the impact on the amount of exhaust gas. The source of the sintering off gas is discussed below. 1. Theoretical Air Requirements During sintering, heat is actually transferred only by the air flowing through it. During the brief sintering time, the heat conduction and heat radiation in the sinter mix are small. When ignited, the uppermost layer of sintering material is heated by the hot combustion gas, reaches the ignition temperature of the fuel, and then sintered at a high temperature. After passing through the ignition furnace, the temperature of the uppermost layer rapidly decreases due to the intake of cool air while the suctioned air is heated. In the combustion zone, the solid material and air are sintered
