Blast furnace is a technique used to raise the temperature up to 2200

1.	Blast furnace is a technique used to raise the temperature up to 2200 degree C in the furnace.(a) True(b) FalseThe question was posed to me in homework.I want to ask this question from Steel and Iron Work in division Rules and Methods of Measurement of Civil Engineering Drawing
Answer» The correct answer is (a) True Easiest explanation: In a blast furnace fuel (COKE), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen ENRICHMENT) is blown into the lower section of the furnace through a series of pipes CALLED tuyeres, so that the chemical reactions TAKE place throughout the furnace as the material falls downward. The end products are usually molten METAL and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace.
