138 An Investigation on the Usage of Alternative Fuels in Bojnourd Cement Industry Mahmood Javidi Shirazy mahmood @yahoo com Date of Submission2014 1 22 Department of Mechanical Engineering IsfahanUniversity of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Dr Alireza Fadaie Tehrani mcjaft@cc iut ac ir Abstract Since introduction of alternative fuels and it s integrations in the cement industry in the past four decades it has received more attentions by raising the energy costs in the last decade Using alternative fuels such as solid waste and tire may decrease the energy costs that affects on cement cost price Despite using solid wastes as alternative fuels in the cement industry of some countries affects there is no significant work in Iran Although one can find many industrial of academic results on this subject there are still some doubts about using alternative fuels such as effects of using alternative fuels on the productive clinker quality clinker conditions exiting gases budgets for permanently using alternative fuels and old tires are proposed as the wealth back period In this project most primitive alternative fuels in the cement industry A brief description on injection systems alternative fuels its advantages disadvantages and previous works in this area are presented Then by using the genetics algorithm software a code for optimizing the amounts of alternative fuels and raw materials in this system is presented This algorithm is able to give optimum amounts of raw materials and alternative fuels in the cost function while it satisfies the constrains and also clinker properties The results show that even a replacement of fuels by waste tires without negative effects on the clinker is possible In the second part of the written software by determining the chemical analysis of the raw materials fuels the new clinker conditions including cooking temperature production phases air volume exiting gas volume are specified The result that reveals there are insensible changes in the system except some changes in the volume of existing gases due to using tire fuels In the next step An economical assessment for using alternative fuel tire in the line of Bojnourd Cement Company was performed The results show that using alternative fuels in the Bojnourd cement industry and probably in other cement factories is economical and do not increase current expenditures In the last section A preliminary design for the channel of injecting tires to clinker and the installation position is proposed Keywords alternative fuels cement industry clinker optimizationPDF created with pdfFactory Pro trial version www pdffactory com
