A 15kg of air is supplied per kg of fuel burnt to the combustion chamber of a boiler using fuel 600kg/hr. the temperature of flue gases and ambient air are 273 C and 32 C. If the minimum draught required to start the flue is 9.5mm of water, find out the minimum height of the chimney?
Determine the height of the chimney to get net draught of 12mm if the total losses are 4mm. the temperature of air is 25<sup>o</sup>C and the temperature of chimney gases is 300<sup>o</sup>C. The mass of air used per kg of fuel used is 18kg. One kg of air occupies a volume of 0.7734m<sup>3</sup> at normal temperature?
The flue gases of natural draught are at higher temperature when compared to flue gases in artificial gas.
Determine the height of the chimney to produce a static draught of 22mm of water if the mean flue gas temperature in chimney is 290<sup>o</sup>C and ambient temperature in boiler house is 20<sup>o</sup>C. The gas constant for air is 29.26Kgm/Kgk and for chimney flue gas is 26.2 Kgfm/Kgk. Assume reading as 760mm of mercury?
Which is the equation used to find chimney diameter?
Which is the net pressure equation used to find chimney height?
