A short but thorough explanation of high emissivity coating.
How much the skin temperature of refractory will increase with emissivity coating?
It does not impact skin temperature. The coating allows more energy to be absorbed by the refractory and re-radiated back into the radiant section since the newly coated higher emissivity surface acts like a black body.
