Waste Heat Recovery from Converter Gas by a Filled Bulb Regenerator: Heat Transfer Characteristics

The iron and steel industry is a high-energy consumption high-pollution industry. Energy recovery in its process of great significance. Converter gas an important by-product the production. It difficult to take effective measures recover waste heat from converter due flammability. In this paper, new technology proposed based on by filled bulb regenerator. mathematical model transfer flow compound regenerator for containing dust established. effects diameter concentration are discussed. results show that temperature declined 132 °C, efficiency was above 90% using system. Resistance loss increased 25% dust; with increase initial dust, rate reinforced. At entrance regenerator, dust’s more obvious, 4.5–8.5%. can provide theoretical basis method.
