Questions answers & calculation on Boiler draught & Chimney

38-Calculate the height of the Chimney required to produce a draught equivalent to 20 mmwc if the temperature of the FG is 180 deg c and ambient temperature is 25 Deg C.And air required for complete combustion per kg of fuel is 7 kg. We have formula, Hw = 353 X H (1/Ta – 1/Tg (Ma+ 1)/Ma) Ta = 273 + 25 = 298 K. Tg = 273+180 = 453 K.

Chimney Length And Draft - How To Improve Performance

1. There needs to be fuel to burn. 2. There must be air to provide oxygen. 3. There must be heat to start the process. Obviously in a chimney fire, the wood is the fuel and a match is the flame so the air providing the oxygen comes in the form of the draft. Draft size needs to be correlated to the capacity that the flue can exhaust.
