ナニワ炉機研究所 List of Products and Services

The rotary melting furnace is a melting technology that uses a pure oxygen burner with a theoretical combustion temperature of 2800°C as its heat source, utilizing clean energy as fuel. It is evaluated to have advantages in addressing issues such as the supply problem of cupola coal coke, the power supply problem of electric furnaces, and the increasing impurity elements in melting materials. Additionally, it is expected to be a friendly melting furnace in the context of global warming. 【Features】 ■ Environmentally friendly melting furnace (CO2 reduction effect) ■ Melting efficiency of 55% ■ Melting furnace that does not use cooling water ■ Capable of handling iron materials containing impurities *For more details, please refer to the PDF document or feel free to contact us.

The waste heat recovery device is capable of collecting a large amount of heat by sucking up and burning the exhaust gases generated during cupola operation, which contain a significant amount of CO gas derived from coke. The air blown into the cupola is preheated to 500°C to 600°C by a heat exchanger. By passing through the heat exchanger, excellent effects such as improved melting efficiency and reduced coke ratio can be achieved. 【Features】 - The recovered heat can be utilized not only for preheating the combustion air of the cupola but also for heating and hot water. - It has been found that high-temperature air is also effective when using high-pressure coke. - The heat generated during the melting process is recycled and reused for melting. - Steam, hot water, and electricity can be effectively utilized without waste. - The heat generation device can raise the temperature to 600°C, enabling a 15% reduction in coke ratio. - The integration of the heat exchanger and exhaust gas cooler has achieved space-saving in the equipment. *For more details, please refer to the PDF document or feel free to contact us.*
