A method of introducing carbon to an Electric Arc Furnace (EAF) used for melting steel, and a composition of matter including carbon, and made in a briquette form. The composition comprises between 45 and 96 weight percent of a carbon-containing material, between 2 and 30 weight percent of a basic oxide, and between 2 and 25 weight percent of a binder material. The method comprises mixing between 45 and 96 weight percent of a carbon-containing material, between 2 and 30 weight percent of a basic oxide, and between 2 and 25 weight percent of a binder material to form a solid material mixture; compressing individual portions of the solid material mixture into compressed briquettes; curing the compressed briquettes into solid briquettes; and adding the solid briquettes into the molten steel in the electric arc steelmaking furnace.

Proposed is a method of emulsifying fuel oil and a desulfurization agent. The method includes (a) a step of adding a desulfurization agent to fuel oil for line mixing thereof, (b) a step of generating droplets in the resulting mixture of step (a), (c) a step of causing the resulting mixture of step (b) to pass through a magnetic field so that the mixture can be magnetized, (d) a step of subjecting the resulting mixture of step (c) to vortex mixing, and (e) a step of causing collision of the resulting mixture of step (d). The method uses fuel oil as a continuous phase and a water-based desulfurization agent as a disperse phase and emulsifies the desulfurization agent in the fuel oil through water-in-oil (W/o) emulsification so that the desulfurization agent can be stably dispersed in the fuel oil. Since the fuel oil and the desulfurization agent are burned together during combustion, sulfur oxides that may occur during the combustion are removed, whereby sulfur oxide emissions are reduced.

A diesel fuel additive includes a cetane number improver and an at least one organometallic combustion catalyst in solution and/or at least one metal-oxide combustion catalyst in suspension.

Biomass based fuel configured to reduce chemical and/or mechanical effects of flue gas on heat transfer surfaces. The biomass based fuel comprises steam-exploded biomass and some combustion additive. The combustion additive is selected from a group of additives that are capable of reducing chemical and/or mechanical effects of flue gas on heat transfer surfaces. The combustion additive may comprise fouling-reducing additive and/or an additive reducing corrosion potential. In addition, a method for manufacturing biomass based fuel configured to reduce chemical and/or mechanical effects of flue gas on heat transfer surfaces. The method comprises providing biomass and steam into a reactor; maintaining said biomass and said steam simultaneously in the reactor, in a pressure of at least 10 bar(a) and at a temperature from 180 C. to 250 C. for at least 2 minutes; and decreasing the pressure in the reactor and/or conveying biomass out of the reactor such that the pressure of the environment of the biomass decreases below 5 bar(a), to produce steam-exploded biomass. The method further comprises adding some combustion additive to the biomass and/or the steam-exploded biomass.

A method for fractionating biomass material according to ash content, the method comprising: grinding the biomass material to produce a ground biomass and sieving the ground biomass through a first screen to yield: a) a first fraction of biomass particles that does not pass through the first screen and which has a first particle size, and b) a second fraction of biomass particles that passes through the first screen and which has a second particle size, wherein the second particle size is smaller than the first particle size, and wherein the second fraction of biomass particles has a higher ash content than the first fraction of biomass particles; and optionally further comprising: passing the second fraction of biomass particles through a second screen having a finer mesh size to produce a third fraction having a smaller particle size and a higher ash content than the second fraction of biomass particles.

Some embodiments are directed to a method to avoid the negative effect of both sulphur and vanadium presence contained in solid fuel used in cement clinker manufacturing line (build-up, kiln rings, etc.). Some embodiments are methods to prepare, dose and use a fuel additive based on an alkaline earth metal to allow the combination of vanadium and sulphur with said added alkaline earth metal, so that corrosion, build-up, crusts and ring formation in cement pre-heaters and kilns due to the presence of those components are avoided.
