- Abstract
- A large number of papers reported measures of coal char conversion rate under combustion and gasifi- 30
cation conditions carried. Measures involved a variety of coal and char types, as well as different exper- 31
imental techniques, ranging from TGA to wire mesh reactors and drop tube furnaces. For oxy-combustion 32
with flue gas recirculation the impact of CO2 on the rate of combustion of char combustion is still con- 33
troversial. 34
In the present paper the rate of carbon conversion in O2/CO2 mixtures typical of oxyfuel conditions has 35
been investigated by conventional as well as innovative experimental techniques, respectively isothermal 36
and non-isothermal thermogravimetric analysis and reaction in an aerodynamic levitator particle reactor 37
(ALPR). 38
Results show that the ALPR provides reliable results also at values of temperature and oxygen concen- 39
tration where thermogravimetric analysis fails. Experimental results have been worked out to obtain 40
simple rate expressions for oxy-fuel combustion. Commonly used kinetic laws, however, proved unable 41
to fit experimental results in the whole range of operating conditions (literal)
