Dec 09, 2013· Coating on tertiary airduct. Dear Ted, Please we experienced some kind of coating on the tertiary air duct, due to this some part of the refractories are being wiped out with the coatings. The chemistry of the sample we picked is attached below.

Holman Cement contracted Western Refractory to retrofit its Polysius preheater which Western had installed as new several years previously. The project involved the installation of a venture section in the calciner, along with a new heat exchanger, two new dedusting cyclones, and a hot air duct.

TERTIARY AIR DUCT (TAD) Air from the grate cooler is filled with highly abrasive clinker dust as well as residual alkali vapors. When it is travelling through the tertiary air duct at a velocity of 2530 m/s and an initial temperature of about 1050°C, it wears down the lining particularly at bends and dampers.

Apparatus for separating oil aerosols from air, including a separating device (11), which is provided as an annular coalescer (22), which coalesces the oil or oil mist in a manner known per se to form greater oil drops which precipitate downwardly by gravitional force in the separating device (11) and downstream thereof, and wherein the separating device (11) is disposed in a housing (14), the ...

riser duct and calciner. One gate is capable of dividing meal into two, three, or four different streams. Tertiary air duct damper To balance the combustion air flow between the kiln and calciner, a tertiary air duct damper is provided for reliable regulation of the tertiary air gases. The damper design features a solid refractory blade for long,

in a tertiary air duct installation. This flow was calculated using Euler method for air motion and Lagrange method for particle motion. The results in this paper demonstrate that study focus on the tertiary air installation is a practical measure without the analysis of other processes in the rotary kiln.
