RECUPERATORS FOR DRI PLANTS
The exhaust heat from the direct reduced iron (DRI) process generally consists of two parallel channels, on which heat exchangers are arranged in series in the flue gas exhaust stream.
The combustion air for the reformer is heated up to 650°C in radiation and convection exchangers. The flue gas inlet temperature is approximately 1150°C.
Feed gas preheaters are installed downstream. These U-shaped tube bundles, preheat the feed gas (a mixture of natural and process gas) to 565ºC to satisfy the facility operating requirements.
