In hot air furnace temperature is the highest part of the vault, a chunky “bottle” shape, bottleneck vertically according to the circular arc gradually shrink into a flue gas passage diameter with 1750mm “”.
In the elevation of + 18.190 m furnace shell diameter expanded with 8010mm, the biggest part of crown, the crown began to merge with large wall masonry.

Precombustion chamber for hot blast stove top position, the total height of about 5m. The roof is covered by a semi spherical, ceramic fiber module under the “burner” system is a cylindrical structure, furnace shell diameter Φ 5094mm, which provided with annular gas, air collector refractory brick, gas, air “burner is provided with a total of 52 small diameter ceramic layer on the 2m high inner wall of the collector “
Precombustion chamber big wall thickness of 1317mm, the combustion space of 2460mm diameter. “Burner” system of flue gas outlet and the vault “bottleneck” cohesion. Gas, air through the external gas, air pipe to, by the gas, air collector 52 rotary jet “burner” implementation of gas combustion.
The low price of clay and silica refractory bricks, accounting for about 96% of all refractory material weight. Only in critical areas such as refractory brick precombustion chamber, a hot air outlet, use a small amount of a higher grade, such as Mo to brick, low creep high alumina brick, but only about 6% of the number of great wall.
