摘要： Disclosed are novel engineered fuel feed stocks, feed stocks produced by the described processes, methods of making the fuel feed stocks, methods of producing energy from the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles and contain a sorbent. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels. In addition, one or more sorbents can be added to the feed stocks in order to reduce the amount of a variety of pollutants present in traditional fuel and feed stocks, including, but not limited, sulfur and chlorine. Further, these feed stocks with added sorbent can mitigate corrosion, improve fuel conversion, extend power generating plant lifetime, reduce ash slagging, and reduced operating temperature.

摘要： Combustion residue can be partially melted and/or sintered in the combustion bed of a grate furnace system. By returning the unmelted and/or unsintered combustion residue, completely sintered inert granulates are obtained. To control the melting and/or sintering processes, at least one of the following process steps is implemented: the residues are returned only as long as, and only in such an amount that the changes thus caused in the essential combustion parameters remain within previously defined tolerance limits; the combustion conditions of the combustion process are changed in such a way as to counteract the changes in the combustion parameters produced by the return; the material composition of the combustion residue is changed by the return of selected fractions of the combustion residue so that the melting and/or sintering process of the combustion residue is influenced; and the material composition of the combustion residue is changed by the addition of additives is that the melting and/or sintering process of the combustion residue is influenced.

摘要： Methods and apparatus for generating a vapor to be injected into a flue gas stream are described. The apparatus includes a fluid vaporization and injection assembly including an input for receiving a non-flue gas, e.g., clean, fluid heat transfer medium, e.g., air; a first sealed coil having an input and an output through which a fluid, such as ammonia, to be vaporized is passed; and a second sealed coil having an input and an output through which a heated second fluid, such as water or steam, is passed. The second sealed coil is arranged to transfer heat from the heated second fluid to the non-flue gas fluid heat transfer medium. The first sealed coil is arranged to absorb heat from the non-flue gas fluid heat transfer medium. An injection unit is coupled to an output of the first sealed coil for injecting the vaporized fluid into a flue gas stream.

摘要： One or more auxiliary plasma torches are provided to a waste processing plant at strategic locations within the chamber and directed towards the waste column. When a bridge forms within the chamber the auxiliary plasma torches may be operated such as to provide an additional heat source where needed, quickly heating the organic solids, which thus pass through the bituminsation and charcoal formation stages quickly. The additional heat source may be in the neighborhood of the bridge, but may also be near the bottom end of the chamber, in which case the additional temperature at the bottom of the chamber effectively moves the combustion and gasification zones for the charcoal to a higher part of the chamber, altering the temperature profile. The heat source also enables the inorganic wastes to be heated rapidly to pass beyond the melting stage relatively quickly. The debridging process may be further enhanced by providing secondary plasma torches at various levels upwards of the primary torches, the secondary torches at any level being operated as and when needed to achieve the desired effect.

摘要： A process for incinerating combustible materials including the steps of: delivering combustible material and inlet gases to a primary combustion chamber, the inlet gases having an oxygen content of at least 50 vol %; burning the combustible material with the oxygen of the inlet gases in the primary combustion chamber producing flue gases and solid particulates as thermal decomposition products of the burnt combustible material; passing the flue gases and particulates to a secondary combustion chamber where further combustion occurs; cooling the flue gases exiting the secondary combustion chamber; returning a portion of the cooled flue gases to at least one of the combustion chambers where the cooled gases moderate the temperature in the at least one chamber; and passing the remaining portion of cooled flue gases on to a flue gas purification system where pollutants in the flue gases and particulates are substantially converted to benign compounds or removed entirely before the flue gases are emitted into the atmosphere.

摘要： The invention relates to a process for combusting black liquor in recovery boilers where the intention is to obtain flue gases which have a low content of nitrogen oxides (NO.sub.x). The invention is characterized in that ammonia is supplied to a part of the combustion air, which part is then supplied to the recovery boiler, as the final portion, at a high level, so that a reducing atmosphere is created in a very large part of the recovery boiler and for a long time, of at least 2.5-5 seconds or more. The invention also includes a recovery boiler for implementing the above mentioned process.

摘要： A pulsating hearth for an incinerator wherein the hearth is suspended on a fixed frame for movement in a limited short arc to urge random size particles burning in a pile on the hearth in a predetermined path intermittently across the surface of the hearth. Movement is imparted to the hearth in periodic pulses preferably by inflating sets of air bags mounted on the frame, which stroke the hearth to move it a short distance from an initial position and jar it against the frame, thus impelling the burning particles a short distance by inertia and concurrently stoking the burning pile upon each stroke, and then returning the hearth to its initial position. The hearth may also have a plurality of nozzles connected to a source of air for delivering gently flowing air to the burning pile on the hearth.
