Abstract

PURPOSE: To reduce CO2 in the exhaust gas to CO and to convert it into a material useful as a fuel, by fringing the high temperature exhaust gas of a lime furnace into contact with a reducing material.
CONSTITUTION: The burning of lime stone 2 in the lime furnace 1 gives quick lime 3. On the other hand, exhaust gas G goes up and moves through a pipe line 6 to a reducing furnace 7. At that time, the temperature of the exhaust gas at an outlet from the furnace top becomes about 1,000W1,200°C. The exhaust gas G is brought into contact with powder coke in a reducing furnace 7 to be converted into CO gas. The temperature of exhaust gas at an outlet 17 from the reducing furnace 7 is as low as about 300W400°C for the heat energy of the exhaust gas has been used to preheat new powder coke charged from a charging aperture 16 for the reducing material. A part of the recovered CO gas is fed from a feed mouth 9 into the lime furnace 1 and the remainder from a feed mouth 10 into the reducing furnace 7.
