According to GB/T 15317-2009 for the energy-saving inspection of coal-fired industrial boilers, the measurement of the air coefficient requires that smoke sampling be carried out at the center of the flue, within 1 meter of the outlet of the last stage of the boiler’s heat-exchanging surfaces. I would like to ask what are the heat-exchanging surfaces at the rear of the boiler, and whether they are located before or after the economizer and air preheater? Also, what does the content of triatomic gases mean?
The tail heating surfaces refer to the convective heating surfaces located within the tail shaft, excluding the furnace chamber. Triatomic gases refer to: SO2, CO2.
