Abstract
An overview of foundry air recirculation methods and description of the engineering effort aimed at the installation of properly engineered air recirculation systems are given in a paper presented at a symposium on Recirculation of Industrial Exhaust Air held October 6-7, 1977 in Cincinnati, Ohio. Yearly heating, ventilation, and air conditioning energy usage averages over 15% of the total energy used by an iron foundry, and during a winter month this percentage may exceed 50%. Throughout the foundry industry, there has been a minimum of engineering idea exchange on air recirculation and a lack of coordinated effort by industry, government, and equipment suppliers. Foundries, as all complex multiprocess facilities, have numerous exhaust streams, all with different temperatures and contaminants. The first process to be fully investigated would be the cleaning room where the exhaust volume is about 20% of the total foundry exhaust. In a current project to determine equipment simultaneous inlet and outlet process emission samples of one cleaning room exhaust stack and collector discharge are to be performed in duplicate at each of five foundries. Next, a demonstration system will be installed in a foundry and the results monitored and reported.
