Preheater training document HCSC.ppt
The hot gases from the kiln enter the lowest stage through the precalciner and then are drawn upwards through the series of heat transfer ducts, each of which is known as a riser duct. The riser duct provides the space where heat exchange takes place between the gas and solid. September 25, 2024 5
Alternative Fuel Substitution Improvements in Low
The reaction begins at roughly 800 °C, and even with a standard kiln line, the enthalpy of the kiln exit gases can cause riser duct dissociation rates of up to 35% [1]. ... the gas velocity in the kiln inlet/riser restriction area should be comparable to the air velocity in the TA duct. However, it must be noted that any elbows, splits, or the ...

Everything you need to know about Kiln Burning …
In this kiln system, the excess air in the burning zone is increased, and the additional oxygen in the riser duct allows additional fuel to be burnt there. This can be an ideal place to burn some waste fuel such as waste oils or tires.

HOTDISC REACTOR
reduces the adverse effects of unburned fuel in the kiln inlet and provides complete control of the process. Incorporating a HOTDISC, as opposed to adding alternative fuels directly to the calciner, eliminates operational disturbances such as cyclone blockages, the need for extra cleaning in the riser duct and emissions of unburned components.

Raw meal enters (at 50 0 C) in the riser duct of second cyclone (from top) and is picked up with the hot gases to first (top) cyclone, where raw meal is separated from gas stream and passed down to second ...
Pyroclon® LowNOx AF
One of the things you want to avoid is fall-through of coarse material to the kiln. The Pyroclon ® LowNO X AF features a specially-designed restricted connection (or orifice) between the kiln inlet chamber and the riser duct that prevents large particles, such as coarse alternative fuels, from entering the kiln inlet chamber.. This restricted orifice also helps maintain the gas balance, not ...

• Minimize heat loss through the kiln shell • Promote (kiln) or avoid (preheater) coating and buildup on the refractory surface To do so they need:
Coating formation in Kiln Inlet
Re: Coating formation in Kiln Inlet. Hi. Coating at kiln inlet ia mainly due to the volatiles like Chlorides, alkalies ( Na2O and K2O) and SO3. To minimise the coating formation, the alkali sulfate ratio should be around 1.1 so that these volatiles will come out as alkali sulfate along with the clinker so that the recirculation inside the kiln circuit will be less.
