Which property is important for bricks used in the combustion chamber & dome of blast furnace stoves ?
Correct answer: A. High refractoriness
- A. High refractoriness
- B. High resistance to spalling
- C. High strength and density
- D. All A., B. and C.
Explanation
The combustion chamber and dome of a blast-furnace stove operate at very high temperatures, so high refractoriness is the key requirement. High spalling resistance and strength are important in other refractory locations, but are not the intended defining property here.
