A process for improving the operation of combustors includes the steps of burning a carbonaceous fuel in a combustor system and determining combustion conditions within the combustor system that can benefit from a targeted treatment additive, wherein the determinations are made by calculation including computational fluid dynamics and observation. The process further includes locating introduction points in the combustor system where introduction of the targeted treatment additive could be accomplished. Based on the previous steps, a treatment regimen for introducing the targeted treatment additive to locations within the combustor system results in one or more benefits selected from the group consisting of reducing the opacity of plume, improving combustion, reducing slag, reducing LOI and/or unburned carbon, reducing corrosion, and improving electrostatic precipitator performance. The targeted treatment additive comprises an alloy represented by the following generic formula (Aa)n(Bb)n(Cc)n(Dd)n(. . .)n, wherein each capital letter and (. . .) is a metal, wherein A is a combustion modifier, B is a deposit modifier; C is a corrosion inhibitor; and D is a combustion co-modifier/electrostatic precipitator enhancer, wherein each subscript letter represents compositional stoichiometry, wherein n is greater than or equal to zero and the sum of n's is greater than zero, and wherein the alloy comprises at least two different metals, with the proviso that if the metal is cerium, then its compositional stoichiometry is less than about 0.7.

摘要:
A method and system for clean burning organic or synthetic material, particularly vulcanized rubber, where fuel is ignited and the heat and smoke by-product is maximized by controlling the amount of oxygen available to the fire. The smoke by-product in an afterburner is reacted with steam, producing hydrogen and carbon monoxide, the products may be collected and stored. The extreme heat in the afterburner reduces the amount of pollutants and toxins in the air. Excess heat generated by burning the fuel may be used to power an engine.

摘要:
A method for removing foreign material such as paints and coatings from workpieces using a mobile furnace. The workpieces are flash heated so that only the surface is heated to remove the coatings without heating the core of the workpieces. Deformation of the workpiece and degradation of the thermal treatment of the workpiece material is thereby avoided.

摘要:
The invention relates to a process and apparatus for treating biogenic residues, particularly sludges, preferably in the area of a clarification plant. Biogenic residues with a variable dry substance are subjected to aerobic drying until an energy-independent thermal treatment can be carried out. During the drying process, evaporated water is discharged in an odor-free condition without releasing freely volatile components, the dried sludge is intermediately stored a number of times and then utilized in preferably a number of successive thermal treatment steps. The two-stage cleaning of the stream of waste gas includes a dust collection unit and an adsorption unit. The waste heat is recycled through a heat exchanger to generate heat and electricity. The apparatus for carrying out the process includes a wet sludge storage container (1), a low temperature drying system (2), storage containers (3, 5) for intermediate storage of the dried biogenic residues, and a thermal treatment system with one or more thermal treatment steps (7, 8). Cleaning of the flue gas takes place preferably by means of a primary cleaning step (10) and a secondary cleaning step (11) for adsorption, for example, with clarified water. Energy recovery (9) from the hot waste gas is ideally carried out before the flue gas cleaning.
摘要:
This invention relates to a furnace device for eliminating volatile organic compounds in exhaust gas. The furnace device has a hollow body (10) with a gas inlet (13) and a gas outlet (11), a positioning device (20) mounted inside the body (10) and an arc generator (30) attached to the positioning device (20). The arc generator (30) has multiple cylindrical chambers (31) for accommodating the exhaust gas and multiple central rods (32) respectively penetrating through the multiple cylindrical chambers (31). In each chamber (31), an inner periphery of the chamber (31) serves as an electrode, and the central rod (32) serves as another electrode. When an effective potential difference is applied to the electrodes, arcs are generated between the inner periphery of the chamber (31) and the central rod (32) inside the chamber (31). Thereby, volatile organic compounds in the exhaust gas are burned and decomposed effectively and completely by the generated arcs.
