摘要： The present invention relates to a multifunctional spontaneous combustion inhibitor for bituminous coal in the form of a foam concentrate, which may inhibit the spontaneous combustion of bituminous coal, prevent the scattering of bituminous coal, prevent the occurrence of problems due to spontaneous combustion, such as a power plant operation failure, bituminous coal waste, and odor generation, enables a bituminous coal power plant to be operated economically, safely and environmentally friendlily through the use of inexpensive bituminous coal, and may be used even at −20° C. by improving the pour point thereof. The present invention is characterized in that a spontaneous combustion inhibitor is prepared in the form of a water-soluble foam concentrate by using an antioxidant, a volatile fraction activation inhibitor, and an emulsifier compound, is mixed with water and air, and is distributed and applied to bituminous coal in a foamed state.

摘要： Structured composite wood pellets comprising wood pellets with a coating at least partially covering the wood pellets, where the coating reduces the generation of dust/fines of the wood pellet upon impact and/or abrasion. The coating may comprise crude tall oil, distilled tall oil, tall oil pitch, tall oil fatty acids, tall oil heads, non-food use sustainable wax, or a combination thereof. The coating may be located at the surface and/or subsurface of the wood pellets rather than throughout, and may be applied at a rate of less than 1 wt. % of the wood pellets.

摘要： A transportable and combustible gaseous suspension includes solid fuel particles suspended in a gaseous carrier. The solid fuel particles have a sufficiently small particle size so that they remain suspended during transportation. The gaseous carrier may include reactive and inert gases. The solid fuel particles may include coal-derived solid carbonaceous matter. Other examples of solid fuel particles include biomass, refined bioproducts, and combustible polymer particles. The combustible gaseous suspension can be tailored to have an energy density at atmospheric pressure which is comparable to conventional gaseous hydrocarbon fuels. The gaseous combustible fuel may be pressurized to a pressure in the range from 2 to 100 atmospheres.

摘要： 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.

摘要： A method for manufacturing dried combustible material includes: a mixing step of mixing a number of particles made of combustible material containing moisture and a dehydrating liquid made of an emulsion containing synthetic resin to form a mixture in which surfaces of the particles are made contact with the dehydrating liquid; and a drying step of forming a synthetic resin coating made of the dehydrating liquid dried on the surfaces of the particles and evaporating the moisture of the particles, to form coated particles including the particles having a reduced moisture content percentage and the synthetic resin coating that covers the surfaces of the particles, and produce dried combustible material made up of the coated particles.

摘要： Sorbent components containing halogen, calcium, alumina, and silica are used in combination during coal combustion to produce environmental benefits. Sorbents such as calcium bromide are added to the coal ahead of combustion and other components are added into the flame or downstream of the flame, preferably at minimum temperatures to assure complete formation of the refractory structures that result in various advantages of the methods. When used together, the components reduce emissions of elemental and oxidized mercury; increase the level of Hg, As, Pb, and/or Cl in the coal ash; decrease the levels of leachable heavy metals (such as Hg) in the ash, preferably to levels below the detectable limits; and make a highly cementitious ash product.

摘要： Described is a method for producing a fuel containing carbon, wherein the fuel is formed by compressing raw material containing a carbon and adding an additive that promotes thermal utilization of the fuel at a specified amount. The additive contains a chemical compound made of the elements calcium and/or magnesium and having or not having carbon. In a first method step, the raw material containing carbon is pressed and in this way a pressed article is produced. Then the additive is fed to at least one area of said pressed fuel article.
