Coke oven gas compressor displacement
Thread Content
The air delivery volume of piston-type coke oven gas compressors is generally controlled cycle by cycle; usually, the load is expressed in terms of the outlet pressure. How can this be converted into the compressor’s outlet flow rate? It is best to represent it using formulas with examples
Calculated using the ideal gas law: P1V1/T1 = P2V2/T2
Our compressor is 6M40; once the inlet and outlet are slightly opened, the gas flows back to the inlet of stage 1 to form a cycle. What I want to know is the flow rate at the outlet of stage 4
What’s mentioned on the second floor are probably the conversion formulas between standard gas conditions and actual operating conditions, haha
I think there’s generally no standard formula for this; it’s all determined based on experience
The air delivery volume of piston-type coke oven gas compressors is generally controlled cycle by cycle, which is acceptable under normal circumstances; however, it is important to ensure that the compression ratio in each stage does not exceed certain limits, as this otherwise can lead to issues such as temperature rise and vibration. If the effect of cylinder clearance is ignored, it can be calculated by using the gas equation of state and a comparison with standard operating conditions.
P1V1/T1=P2V2/T2 Consider the correction factor again
For your reciprocating compressor, set it to four cycles per minute with a slight adjustment; you can determine the consumption amount based on the response from the equipment behind it； A certain degree of opening during the fourth cycle will cause an increase in the inlet pressure and temperature. If the outlet pressure and temperature are specified as design parameters, you can use the formula P1V1/T1=P2V2/T2 to calculate the inlet flow rate under the current conditions. Then, using that formula along with the calculated values for inlet flow rate, pressure, temperature, as well as outlet temperature and pressure, you can determine the outlet flow rate under those conditions.
