Experimental Study on CO2 Tracing Method for Semi-coke Combustion in O2/CO2 Atmosphere
In order to study the combustion performance of semi-coke under the condition of oxygen enrichment,a self-made constant temperature vertical tube furnace was used to conduct the constant temperature combustion performance of semi-coke by CO2 tracking method.The results show that the combustion path of semi-coke is obviously changed under the condition of oxygen enrichment.Compared with the conventional air atmosphere,the combustion time is extended by about 100s,and the CO2 production also changes obviously.In the process of constant temperature combustion,the total amount of CO2 produced decreases with the increase of oxygen concentration.This conclusion provides a new idea for emission reduction in the process of blast furnace injection semi-coke iron making and"double carbon"under the condition of oxygen enrichment.
