QUALIFICATIONS & EXPERIENCE:
MARTIN J. HANNINEN,
Metallurgist, Pelletizing Systems
Airflow Surveys and Process Efficiency Studies
Conducted complete and partial pellet plant process airflow surveys
and system efficiency studies on all of Cleveland-Cliffs, Inc. managed
mines including: the Empire Mine, Hibbing Taconite Mine, Northshore
Mine, LTVSMC Mine, Tilden Mine and Wabush Mine. Process airflow survey
results are summarized below.
Complete system mass and heat balances
Complete system pressure/temperature profiles
Role of system ingress and egress air leakage
Process fan efficiency optimization
Furnace air balancing
Conducted airflow surveys on all of the vacuum pumps operating at Cleveland-Cliffs,
Inc. managed Empire and Tilden Mines.
complete airflow surveys and power generating efficiency studies
on Wisconsin Power’s Presque Generating Plant Units 7, 8 and
Designed and sized proper process fan wheel extensions (tips) on the
Empire Units 1-4 pelletizing process fans that resulting in using all
of the available motor horsepower and increased pellet production on
all four pelletizing units.
Designed and sized proper process fan wheel diameter reductions that
saved operating horsepower on a number of the Tilden Units 1 and 2 pelletizing
Results of process airflow surveys led to the installation of variable
frequency drives on a number of the Wabush Mine Pointe Noire Pellet
Plant process fans that resulted in electrical energy savings.
Results of process airflow surveys led to the design and purchase of
smaller diameter wheels on a number of the Northshore pelletizing process
fans that resulted in electrical energy savings.
Results of airflow surveys resulted in the installation of variable
frequency drives on the Presque Isle Power Generating Plant Units 7-9
forced air fans that resulted in electrical energy savings and reduced
noise reporting to the community surrounding the plant.
