Hot Blast Stovean overview ScienceDirect Topics

Chequerwork assemblies of silica bricks are used in hot-blast stoves that regeneratively preheat combustion air for iron-making blast furnaces to temperatures of 1200–1300°C. Silica bricks have a surprisingly good refractoriness-under-load at temperatures only 50°C or so below the melting point of pure silica 1723°C).

Measurement of O2 Concentration in Hot Blast Stoves

Measurement of O 2 Concentration in Hot Blast Stoves Essential to Improving Combustion Efficiency. In a hot blast stove the by-product gas produced in a coke oven is burned to preheat the air blast for the blast furnace. To improve the combustion efficiency and conserve energy in a hot blast stove it is essential to be able to control combustion by measuring and adjusting the oxygen
