Fuel Coustion and Heat Transfer in a Furnace – IspatGuru

2019/12/26· If the coustion is fuel lean, meaning there is more O2 than required to fully burn the fuel, and then there is excess O2 in the exhaust products. The fuel has a significant influence on the heat transfer in the furnace coustion system. One of the most important properties is the heating value of the fuel.

Does Oxygen Burn? Flammability of Oxygen - ThoughtCo

2019/11/14· A flammable substance is one that burns. Though oxygen does not burn, it is an oxidizer, which means it supports the process of coustion.So if you already have a fuel and a fire, adding oxygen will feed the flames. The reaction can be dangerous and violent, which is why it''s never a good idea to store or use oxygen around any sort of flame.
