May 05 2021 · Oxygen O2 supports combustion. Oxygen itself is non-flammable but it supports combustion. It can cause fire or explosion in combustable materials. Avoid that oxygen comes in contact greasefat and oil. Never use oxygen as substitute for compressed air. For oxygen the following is valid: 1 nm3 = 1.311 kg; 1 kg = 0.763 nm3; 1 bar = 14.5 psi; 1 ...

For Example: 4.5% Excess Oxygen reduced to 2.0%. 1.0 (0.7972 / 0.8308) = 0.04044 = 4.04%. NOTE: Because some boilers operate with a very high percentage of excess oxygen it is common for the first year savings to be substantially higher than this.
