As you enlighten to calculate the GJ  of kiln.

Here is my calculation of heat (In GJ) for kiln . My objective is to cal the operating parameter for Kiln Burner

Thermal load in kiln= 6462x30000= 193GJ

6462= Combustible flow or feed rate in KG/HR

30000= Calorific value of petcoke.

As per your calc . this thermal load is required to be multiplied by 365(ie air in kg/GJ of fuel ) . Well this Gega joule I have calculated in approach to calc the thermal load of kiln. Perhabs I may be wrong , kindly get me in right direction .

Continuing to process envisages by you

193X365=70445kg/hr

This result does not in resonance of what I have been given from my alternate source. As per alternate source the result is

Conveying air volume-3374 NM3/HR (@ 0°C, 1 atm).

Discharge pressure – 7900 MM WG.

Conveying Pipe Size – 200 NB Sch 40

If I convert the mass flow in volume flow than also the result wouldn’t match with the resulted air volume ie 3374NM3/HR.

Pressure and pipesize being desin , taking site condn parameter. But my worry is , how to calculate the volume , probably they must have considered heat value.

Iam looking forward volume flow calculation.

Thanks in anticipation

Conveying air is only a part of the combustion air.

 If you are interested in calculating a pneumatic transport, for transporting pulverized fossil fuels, a range of 4-7 kg fuel/kg air would be expected for short distances.

what are design steps for rotary kiln?
