There are thirteen units of blast furnace dehumidifiers now at works in our country. We have four methods : dry type lithium chloride method, wet type lithium chloride method, refrigerating method, and blower discharge side-cooling method. Each method has its merits and demerits. It seems there is no conclusive factor to select one from these four. Among these dehumidifying methods, we gave attention to the blower discharge side-cooling method which had the most compact equipment. Then we developed the direct contact cooling method. After we manufactured a test plant on a scale of 1 to 20 and made an actual gas test, we equipped at No.2 BF in our Kokura Steel Works in May this year. This plant is working satisfactorily. We developed this method for the purpose of reducing the equipment cost and operating cost. Our direct contact cooling plant is constituted by the heat pipe type exchanger, direct contact air cooler, and high-efficiency mist separator. In comparison with the conventional type, the installation space and equipment weight are about half. So we could reduce the equipment cost drastically.
