2022-6-17 Nozzle position: When the secondary air enters the rotary kiln burner, the mixing of the primary and secondary air is weak, which extends the burning time and makes the flame extend. For example, before the secondary air enters the kiln, the mixing between the primary and secondary air will be strengthened to shorten the flame.

2020-3-30 TCL is located in Claxton Bay, Trinidad & Tobago. It operates two wet process kilns, kilns 3 and 4, both of which are fueled by natural gas. Kiln 3 (1100t/day, L = 145m, Ø = 5.2m) was commissioned in the mid 1980s. It has a specific heat consumption of 1730kCal/kg of clinker.

This is because the primary function of the air channel pipe is said to shape the flame and swirl the air whilst introducing the coal dust, to enable efficient combustion.
