BLAST FURNACE
ADI Industrial Services

ADI-IS designs and manufactures its own endoscopic devices enabling an appropriate technical answer to specific needs.

  • Standards endoscopic devices have an outer diameter of 38 mm enabling introduction in a 2” valve (thermocouple f.i.).
  • Outer diameter, suitable endoscope lengths and various vision angles enable cowpers, main pipe and bustle pipe inspection
  • INDUSTRY CHALLENGES FOR HOT BLAST AIR CIRCUIT

    Efficient uninterrupted operations of hot blast air supply to the blast furnace -> RELIABILITY

    SStable process conditions avoiding fluctuations since there is no room for mistakes -> CONSISTENCY

    Low costs operations and down time minimization -> RETURN ON INVESTMENT

    Energy efficiency -> LOW EMISSIONS

    SOME (VERY) GOOD REASONS TO PERFORM ENDOSCOPY WITH ADI-INDUSTRIAL SERVICE

    DOMES AND CHECKERS

    the fall of bricks on the checker, partially blocked, poor heating and higher energy use.

    BURNER AND GRID

    Soon or later fall of bricks on the burner grid leads to bad blasting, undesirable turbulences and higher energy use.

    COMBUSTION CHAMBER

    the fall of bricks, cracks, undesirable interferences between the combustion chamber and the checker leading to heating issues and energy intensive.

    BUSTLE PIPE AND MAIN PIPE

    The fall of bricks, partialy blocked, poor hot air supply to the tuyeres and higher energy use.

    COOLING ELEMENTS

    Efficient cooling staves are aiming to balance the thermal load and associated wear of the inner refractory lining of the furnace, and consequently to protect the shell. The efficiency of the cooling systems of a BF plays a key role in an extended campaign life of a BF and hence the operating costs. Cooling staves are subject to significant thermal loads changes which may lead to stave failures due to cracks, water leakage, bending, abrasion and resultant wear. The pictures, recorded during endoscopic inspection, show how lime scales can damage the inner part of the water piping, leading to poor cooling, wear and possible water leakage.
