Embodiment
[0017] Embodiment: by implementing table 1 proportioning (component unit is wt%), first MMT is dissolved in xylene and / or diesel oil, then add sulfonate type anionic surfactant and water successively, under lucifuge condition Stir and mix evenly to obtain the liquid composition of the present invention.
[0018] The compositions of Examples and Comparative Examples were respectively added with Shenmu anthracite coal powder (see Table 3 for ingredients) with a coal powder amount of 1.2wt% and sprayed and stirred, stirred and mixed for more than 1 hour, and then sent to the combustion furnace, and the amount of coal fed was increased every hour. The sample size is 40kg, and under the conditions of primary wind speed 80Pa and secondary wind speed 300Pa, the influence of each sample on the carbon content and denitrification efficiency of the fly ash during the coal combustion process is shown in Table 2.
[0019] Note: The experiment was carried out on the one-dimensional furnace ...
