摘要： Mineral additives and a method for operating a waste-to-energy furnace are provided in order to improve its operational performance and availability, increase the lifetime of the combustor building materials (refractory walls and heat-exchanger metallic tubes) and flue gas treatment equipment, improve ash quality, reduce emissions and avoid combustion problems such as agglomeration, slagging, deposition, and corrosion. A method for operating a waste-to-energy furnace, such as a fluidized bed reactor, pulverized-fuel combustor, grate combustor includes introducing mineral additive into the furnace. The method further includes heating at least a portion of the mineral additive either intimately in contact with the fuel, such that the ability of mineral additive to induce crystallization of the surface of forming ashes is enhanced, or minimizing the contact of the mineral additive with the fuel and the forming ashes, such that the solid-gas reactions between the mineral additive and the volatile compounds in the flue gas are favored and the mineral additive power to capture at least a portion of the inorganic volatile compounds present in the furnace is enhanced.

摘要： A fire grate assembly for stoker incinerators. A plurality of stationary and movable grate members are alternately arranged in the assembly. The assembly also has a preventing member, such as a liner plate, which is detachably mounted to an end of each of the movable grate members for preventing the stationary grate members and the movable grate members from directly contacting each other, while allowing the movable grate members to be linearly movable relative to the stationary grate members. The preventing member is replaceable and can have a countersunk hole, thus being adapted for bolting the end of each of the movable grate members.

摘要： In a process for the thermal treatment of solid materials (3), in particular refuse, in which the solid materials (3) are burnt/gasified or pyrolized in a first step (5) with a lack of oxygen, and then, in an afterburning zone (14), the flue gases (6) from the first step (5) are mixed with an oxygen-containing gaseous medium (15) and are burnt with complete burn-off, the flue gases (6) emerging from the first step (5) are firstly actively homogenized in a mixing zone (7) with the addition of a gaseous oxygen-free or low-oxygen medium (8) before they are mixed with the oxygen-containing medium (15). Then, the homogenized flue-gas stream flows through a holding zone (13), in which it stays for at least 0.5 second, before, in an afterburning zone (14), the medium (15) which serves to ensure complete burn-off of the flue gas is added. The process according to the invention is distinguished by simple process steps and by a reduced level of pollutant emissions, in particular NOx, compared to the prior art.

摘要： A coincineration process whereby sewage sludge or other toxic liquid chemical waste is incinerated with a supplemental fuel such as municipal refuse, coal, sawdust, tire chips and the like involves introducing the sewage sludge into the incineration zone by means of a pressure spray nozzle or a spinning cone or disc atomizer. In the form of ultrafine solids, liquid or gas, a supplemental fuel may be introduced with the sewage sludge. Supplemental fuel may also be introduced into the incinerator by conventional means. Addition of tire chips in the feed provides in a higher incineration zone temperature and significantly reduces dioxin compounds present in the incineration zone off gas. Also, to reduce the scaling and fouling of the boiler tubes and incinerator, to increase the density and pumpability of the sewage sludge, and to eliminate metal salt deposits from the incinerator, the boiler feedwater and the sewage sludge are each contacted with an electromagnetic field device prior to heating.

摘要： A method and apparatus are provided for enhancing the efficiency of combustion in a combustion chamber with the use of acoustic energy. A means for generating acoustic energy (34) is located in relation to a combustion chamber (12) such that acoustic energy is transmitted into the combustion chamber (12) resulting in excitation of particulate and gases flowing therein and increased combustion efficiency. In the preferred embodiment, increased combustion efficiency is accomplished by operation of a horn (34) located at substantially the top of the combustion chamber (12) for generating acoustic energy into the chamber (12).

摘要： A method for burning fuels, particularly garbage, in incinerators with a stoker grate, for which the primary air is supplied below the stoker grate into the fuel layer and the secondary air is supplied above the fuel layer, is controlled in such a way that the intensity of the combustion of the fuel on the stoker grate is increased by increasing the oxygen content of the primary air and the intensity of the combustion in the secondary combustion zone is choked by decreasing the oxygen content in the secondary air. Flue gas, preferably from the combustion process, is recirculated in order to reduce the oxygen content of the secondary air.

摘要： A method for controlling combustion in a furnace into which combustible material, e.g., urban refuse, industrial waste, and a controlled quantity of combustion air are fed. The furnace includes a mixing/stirring region where unburnt gas and secondary combustion air are mixed and stirred. A part of exhaust gas derived from the furnace is blown into the mixing/stirring region depending on variation in the quantity of the secondary combustion air, and a flow rate of mixture gas consists of the exhaust gas and the secondary combustion air to be fed into the mixing/stirring region is maintained within a predetermined region so that effective combustion takes place.
