Use the flue gas oxygen content standard? Use negative pressure at the furnace top?
Those who pass by must leave some trace... Have you all heard? A major breakthrough has been achieved in the thermal conductivity of plastics! The thermal conductivity has increased from 0.2 to 50; in the future, fans and heat sinks will also be able to effectively dissipate heat. Common electronic devices such as computers and smartphones are set to undergo significant changes in terms of their size. Is there anyone else who is looking forward to this as much as I am?
An excess oxygen content of 1-2% ensures complete combustion; the negative pressure in the furnace is 2-3 MMH2O. The temperature of the flue gases is recovered as much as possible. Nowadays, air preheaters are generally installed in such systems to recover the temperature of the flue gases
There is another important parameter, the carbon monoxide level, which is used to determine directly whether the combustion is complete or not.
