Stove with a self-supporting dome and an internal combustion chamber

Conventional stoves with a blast temperature of about 1000°C were previously used to heat the blast for the blast furnaces at the metallurgical plant in Koshitse, Slovakia. An increase in the useful volume of these furnaces made it necessary to heat a larger volume of blast and increase its temperature. A new stove with a self-supporting mushroom-shaped dome was built. The stove was provided with a checkerwork made of high-quality refractories and a lining with keyed joints was installed in the combustion chamber. The combustion products from the combustion chamber are discharged in the vertical direction. The lining of the dome is not connected to the outside lining of the stove. __________ Translated from Metallurg, No. 7, pp. 41–44, July 2006.
