hi, this usually occurs not only in coal combustion but also in species transport reactions. i that if you have given the any wrong values of preexponential factor, activation energy and heat of formation. you may get that thing. check weather the above values are correct. all the best.

well, you might wanna change the default values of those parameters sumanth suggested. at times it do occurs for early iterations and dies off later. also you might want to consider switching your initialisation zone. I do had if initialised it from certain zone. check your grid too. just make tripple check to see you've the right information for particular parameters or variables.
