bypass ratio waste gas kiln preheater
Part II Source category (b):
For preheater and precalciner kilns, this is sometimes accomplished by alkali bypass systems at the preheater tower that removes alkalis from the kiln system; Alkali bypass exhaust gas: At facilities equipped with an alkali bypass, the alkali bypass gases can be released either from a separate exhaust stack or from the main kiln stack.

If a saving (or loss) in the high temperature zone in a kiln of say 1 00 kJ occurs the possible gain in fuel heat consumption will not be 100 kJ but rather 130 to 150 kJ. That means that the primary saving (in terms of heat balance item) will be multiplied by a factor of up to 1 .5.

This relation does not apply for a dissociating gas, because the molecular weight of the gas changes as molecular bonds are broken. Note the importance of assuring that R and the heat capacities are in consistent units in this equation. Another important gas property is the ratio of heat capacities defined by k .
