The present invention is directed to additives for coal-fired furnaces, particularly furnaces using a layer of slag to capture coal particles for combustion. The additive(s) include iron, mineralizer(s), handling aid(s), flow aid(s), and/or abrasive material(s). The iron and mineralizers can lower the melting temperature of ash in low-iron, high alkali coals, leading to improved furnace performance.

Low sulfur coal additive for improved furnace operation

The present invention is directed to an additive, primarily for low sulfur and high alkali coals, that includes a transition metal and optionally a halogen to effect mercury oxidation.

Additives for mercury oxidation in coal-fired power plants

A method using retardant to inhibit solidification of slurried fly ash particles that were collected on a collection surface. The slurried particles are transported in a pipeline to a collection or disposal site during or after the addition of the retardant to the slurry. The retardant can be a dispersant, a deflocculant, a scale inhibitor or a sequestering agent such as a phosphate, organic phosphate, polymer, and mixtures thereof.
