Understanding the Impact of Excess Air | Firebridge

For example, consider a 100 million btu/hr burner with a 10:1 turndown. When it is firing at 100 million btu/hr, the excess air is 15%. However, at the minimum firing rate of 10 million btu/hr, the excess air could be . To get an accurate estimate of the energy savings, systematic measurement and calculation needs to be done.
