  • Low sulfur coal additive for improved furnace operation
    Patent number: 11168274
    Abstract: 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.

  • Fly-ash slurry with solidification retardant
    Patent number: 6221001
    Abstract: 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.
