Design of two-chamber flue gas heat exchanger
In October, we handed over completed workshop documentation to our client ForSTEEL for a two-chamber heat exchanger. The exchanger will soon be installed at the Trinecke zelezarny steel mill, where it will heat combustion gas and air utilizing blast furnace flue gas.
Our static calculation and optimization of the heat exchanger steel structure design respect the highest working temperature of flue gases (400 °C for up to 15 min.) and operating temperature of the blast furnace gas (240 °C max. at the highest working overpressure of 20 kPa).
