Title: Coal agglomeration in blast furnace injection coals

It was found that coals defined as 'caking coals' showed consistent agglomeration during DTF injection, a potentially problematic effect regarding blast furnace injection. Agglomeration percentages (as defined by sieve classification) for the industrially problematic MV4 coal were 11% and 23% for the granulated and pulverised samples respectively.

This high pressure, hot air (or blast) is then injected together with pulverised granulated coal into the furnace at tuyere level, just above the hearth and flows upwards to the top of the furnace. The air reacts with carbon bearing materials at the tuyeres to form carbon monoxide, reducing the iron ore to iron as it travels up the furnace.
