Cooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor. This equivalent ton is defined as the heat rejection in cooling ...

1.65 = The conversion factor of ton feed per ton clinker. Qk = The exhaust flow of the kiln (dscf/ton feed). Qc = The exhaust flow of the clinker cooler (dscf/ton feed). Qab = The exhaust flow of the alkali bypass (dscf/ton feed). Qcm = The exhaust flow of the coal mill (dscf/ton feed). 7000 = The conversion factor for grains (gr) per lb.
