How to calculate the false air for a cement plant

2008-11-10  How to calculate the false air for a cement plant production line? I know that there is an equation used to calculate the false air for each stage in the preheater & other points, but i don't know this equation. I guess the inputs for this equation are (clinker production kg/h) & (kiln thermal consumption kcal/kg) & (O2 %).

calculation of false air entry in coal mill Page 1 of 1

Re: calculation of false air entry in coal mill. You can use: 1. Mass balance. 2. Heat balance. 3. Oxygen balance (oxygen correction) easiest is Oxygen balance that you measrue oxygen going in and out and do oxygen balance base on this formula: V2 = Vt (21-Oout)/(21-Oin) V2 = false air valume. Vt = total volume (V1 + V2) Oout = Oxygen % in

For a medium-size cement plant with a kiln capacity of 3,000 tpd the oxygen demand is estimated to be around 25 to 30 tph. For logistical reasons, such amounts of oxy-gen can only be provided by an on-site oxygen supply system.

Process, Resource Impacts

2020-5-1  False Air Inspection Instead of leaking out from within the process, there is now a problem with ambient air being sucked into the system, called false air. Depending on the point of entry, false air has different undesired effects. That is why a lot of effort is made to keep process systems tight. Main Impacts of False Air

Waste heat availability in the raw meal department of

2018-3-1  The false air temperature is low (typically between 0 and 25 °C), which means that some of the sensible heat in the hot gas is heat up the false air, reducing the drying potential of the gas. Since one of the main purpose of sending hot gas via the AFM is to dry the raw materials, more air could have been bypassed if the false air was reduced.
