How to calculate RTO burner required:

For a 95% Effective Heat Return

燃料的要求是:

Example: 10,000 SCFM RTO Unit

Operating with no VOC – Burner required is: 10,000 X 90 = 0.9 mmbtu /人力资源
106

For quick start-up – Burner required is: 3 X 0.9 = 2.7 mmbtu /小时(2.5 – 3.0 mmbtu /小时)

For a 90% Effective Heat Return

燃料的要求是:

Example; 10,000 SCFM RTO Unit

Burner required is: 10,000 X 90 X 3 = 1.8 mmbtu /人力资源
106

Any VOC in the fume stream will reduce fuel requirement.
For Expanded Polystyrene (EPS) plants, typically each pound of pentane reduces the fuel requirement by 19,500 btu. So for a 10,000 SCFM RTO with pentane in collection stream at 20 lbs/hr:

Btu value is 20 X 19,500 = 0.39 mmbtu /人力资源
106

For Flexographic Printing & Packaging industry, use 15,000 btu/lb
