Claims
- 1. A method of providing stability of particle distribution and redispersibility in the transporting and combusting of coal in combustible liquid comprising the steps as follows:
- storing a readily pumpable, readily redispersible slurry of solids mixture in a combustible liquid which is neither a pseudo-plastic nor a thixotropic fluid, said liquid not being highly viscose such as methanol said solids mixture comprising from about 90 to about 99 weight percent coal particles and from about 1 to about 10 weight percent finely divided wood particles,
- said wood particles being of a size less than the largest coal particles and each having a particle size no larger than about 50 Tyler mesh (297 microns),
- pumping said readily pumpable and redispersible solids mixture in said combustible liquid as a slurry with substantially no fibrous matrix being formed and said wood particles remaining discrete as a stable dispersible slurry,
- injecting said stable dispersible slurry through a nozzle means for fine dispersion in a combustion zone, combusting said slurry.
- 2. The method of claim 1 wherein coal particles and said wood particles each have a particle size no larger than about 100 Tyler mesh.
