Vertical Shaft Kiln Vs Rotary Kiln
Aug 29, 2020 · Kilns to produce cement are almost equally old. Now cement kilns can be divided mainly into 2 types: vertical shaft kiln and rotary kiln. The vertical kiln is the older type and its origin dates back to the 5 th century AC. Rotary kilns were first used in 1880. Around the 20 th century, they replaced vertical shaft kilns almost everywhere.

BURNERS AND CONTROLS
Typically, depending on the kiln or furnace back pressure, gas pressure and burner head design, the venturi throat area should be approx. 4050% of the total burner port area. Mismatching may result in a decrease in mixture velocity producing inadequate burning or at worst "flash back".
Optimizing the preheating zone in a tunnel kiln
In many tunnel kilns, in the higher temperature range (600 – 800 °C), highvelocity burners are installed for temperature homogenization. Energy input is not usually necessary for the process and, in isolated cases, it can even be detrimental. With the use of hightemperature circulating fans, a much more energyefficient solution is achieved.
