GPC fines loss is much lower in a shaft calciner (typically <3%) due to the absence of a counter-current flue gas stream [2] inside the calciner. As GPC prices increase, rotary kiln calciners are incentivized to reduce GPC fines carryover. Since power prices are normally fixed, it is more favorable for a calciner to convert as much GPC

oil, and natural gas may all be fired in rotary kilns. Product coolers and kiln feed preheaters of various types are commonly used to recover heat from the hot lime product and hot exhaust gases, respectively. The next most common type of kiln in the United States is the vertical, or shaft, kiln. This kiln can

2011 Shaft Calciner TDS Trial The differences between rotary kiln and shaft calciners have been described previously [7]. Rain Carbon operated a small 20 kt/yr shaft calciner in China from 2009–2015. In 2011, a trial was carried out with two high volatile matter (VM), fine particle size GPC's. One was a very low S coke (0.4%)

Shaft technology is lower cost in terms of CAPEX and maintenance, provided the VM content in the GPC blend used is under 11 % and excessive fines do not clog the coke descent through the shaft.
