    Abstract: There is provided a process for operating a coal- fired furnace to generate heat. The process has the steps of a) providing the coal to the furnace and b) combusting the coal in the presence of a first slag- reducing ingredient and a second slag-reducing ingredient in amounts effective to reduce slag formation in the furnace. The first slag-reducing ingredient and the second slag-reducing ingredient are different substances. The first slag-reducing ingredient is selected from the group consisting of magnesium carbonate, magnesium hydroxide, magnesium oxide, magnesium sulfate, and combinations thereof. The second slag-reducing ingredient is selected from the group consisting of copper acetate, copper nitrate, aluminum nitrate, aluminum oxide, aluminum hydroxide, and ammonium phosphate. There is also provided a method for reducing slag formation in a coal-fired furnace.

    Abstract: A process for burning coal or other carbonaceous fuels captures sulfur and other undesirable compounds are captured and retained in non-reactive ceramic-like form after the combustion phase. The process involves addition of multiple element alkali powders and/or sorbents preferably containing oxidizing anions such as nitrates and nitrites, preferably based on calcium. In various embodiments, the remediation materials when applied in a complex powder and/or liquid containing multiple elements, result in higher sulfur capture than the materials would otherwise achieve on an individual basis. In a preferred embodiment, the sorbents contain elements that minimize or lower the melting point of the ash. This leads to lowered cohesiveness and toughness of the ash so that less ash builds up on the boiler and better heat transfer is obtained.

    Abstract: A method for preventing the sintering of bed material caused by the alkali metal alloys of low melting points contained in the fuel of a circulating fluidized-bed boiler or a fluidized-bed boiler. In the method, an auxiliary admixed with water is added to the fuel before feeding the fuel into the furnace, the auxiliary reacting with the alkali metal mixtures of low melting points contained in the fuel. The auxiliary is introduced admixed with water either in the form of a clearly aqueous solution or a damp slurry which mixes well with the fuel. There are many ways of determining the amount of auxiliary needed.

    Abstract: A process is provided using non-food or limited-feed agricultural residue and energy crops for energy production, such as ethanol or electricity generation. The agricultural plant material is harvested and baled. The bales are transported to the processing site for storage or immediate processing. The bale strings are first removed, and then the broken bales are shredded. The shredded plant material is then ground to a small size. The ground material is then pelletized to produce densified pellets of the agricultural plant material. The pellets are cooled and then stored or transported to an end user.

    Abstract: Methods involve adding sorbent components, such as calcium oxide, alumina, and silica, as well as optional halogens as part of environmental control. Use of the sorbents leads to significant reductions in sulfur and mercury emissions that otherwise would result from burning coal. Use of the sorbents leads to production of waste coal ash that, while higher in mercury, is nevertheless usable as a commercial product because the mercury in the ash is non-leaching and because the coal ash has a higher cementitious nature by virtue of the increased content of the sorbent components in the ash. Thus, the methods involve adding powders having qualities that lead to the production of a cementitious coal ash while at the same time reducing emissions from a coal burning facility.
