Abstract
1. A notable error of heat balance of the cement rotary kiln hitherto depends upon mismeasurements and miscalculations of radiation and convection heat losses of the kiln and cooler shell, chiefly.
Then author measured them by means of “elongation method”, which is contrived by myself, with a view to make a correct heat balance.
2. The loss due to flue dust, which is ignored as yet, play an important part of heat losses.
3. Author atempt to manifest the calculation method of heat balance in order to popularize it in practical use, expecting to improve of the kiln conditions and combustion efficiency of fuel, which is proposed by myself.
