Magnesium Hydroxide
(OP)
Does anyone have any experience injecting Magnesium Hydroxide into a coal fired furnace to aid in the reduction of slag formations? Seems like it works on humans!

RE: Magnesium Hydroxide
I have been involved, some years ago now, in some demonstration work on roasting a waste material where sodium content was high. To prevent lumping due to viscous slags we added kaolin with some good results. Kaolin was cheap. We didn't consider refined MgOH. The source of the kaolin was important and I guess this will be true with the coal in your case. The minor impurities, in the kaolin, coal or MgOH, will have a big effect on the success of any additive. Also how/where it is injected.

Slagging in coal fired plants often happens when the furnace is too small and thus temperatures around the burners are very high. Here magnesium oxide can successfully be added to the coal flow to reduce this slagging.
Check out www.pentol.com for additives of this kind!

There are knock-on effects, we will reduce the carbon in ash due to a more complete combustion. This is becoming more relevant as de-NOx regulations kick in and so overfire air has to be increased (as one method of reducing NOx).
Do please look at our website or make contact with us and we would be very happy to answer direct questions.
Apologies for the solicitation!
