Triple shaft lime kiln

Apr 14, 2021

lime kiln gas made the solid fuel mixed feed lime kiln the num-ber one choice for the sugar industry. In case of lime kilns, the switch from coke/anthracite to natural gas is an option used to reduce CO 2 emissions. In North Africa and North America the situation has already changed and natural gas as lime kiln fuel is gaining more and more
