制砖行业是建材行业中的耗能人户。为了提高焙烧窑的热效率,提高企业的经济效益,我们在制坯过程中,将部分碎煤按一定的比例,均匀地掺入到原料土中(以下简称内掺),这部分内掺燃料在坯体中燃烧时产生一定的热量。这部分内掺热量首先加热靠近的坯体,就后再向四周漫延。其热效率与外投煤的热效率相比,将高出好几倍,是一种节能的新工艺,但内掺的比例,内掺燃料的颗粒直径等都是值得探讨的问题。下面就上述问题进行分析,供参考。 1、内掺量。一般的说每块九五红标砖砖坯的内掺热量取2090kJ左右为宜。
Brick industry is building materials industry energy households. In order to improve the thermal efficiency of roasting kiln, and improve the economic efficiency of enterprises, we in the process of billet, some of the broken coal by a certain percentage, evenly mixed into the raw material in the soil (hereinafter referred to as internal mixing) Burn body produces a certain amount of heat. This part of the first heat mixed with the body near the heat, then spread to the surrounding. The thermal efficiency is several times higher than the thermal efficiency of the outside coal, which is a new energy-saving process. However, the proportion of internal mixing and the particle diameter of the internal fuel are all worth discussing. The following analysis of the above issues for reference. 1, the amount of content. In general, each of ninety-five red brick brick adulteration of about 2090kJ appropriate.
