Definitions

  • US patent no. 6,269,754 discloses a steam generator for superheated steam for incineration plants with corrosive flue gases. It essentially comprises a radiation section and a convection section, having at least one superheater and having plates arranged on the inside of a wall of the radiation section, a space is being provided between the plates and the wall of the radiation section. At least a part of the superheater is being arranged as a wall superheater in the space in the radiation section.
  • This space contains a less-corrosive gaseous atmosphere, which is at a higher pressure than the pressure of the gases in the combustion chamber.
  • Bottom ash In general bottom ash is called slag.
  • Bottom ash or slag is defined as the ash removed from the bottom part of the combustion zone of the boiler. Ashes are defined as the residual products from the combustion process.
  • the sintering reactor is a reactor that heats the ash/slag so that leaching properties are improved. This means that the leaching of heavy metals from the ash/slag is re- prised.
  • the reactor is located - in the direction of the flow of the refuse - after the grate arrangement (21 ).
  • a corrosive gas flow is the result in the pre-process, and conversely at reference numeral 6, a less-corrosive gas flow is the result in the post-process.
  • the less-corrosive gas flow is the output from said reactor (16), possibly fired with a fuel (18), typically a secondary fuel (18).
  • the secondary fuel is selected to develop flue gases that are less corrosive than the flue gases from said refuse or waste.
  • an integrated bottom ash treatment and improved electrical plant efficiency may be obtained by the concepts shown in the figure. It is thus advantageous to combine the high-efficient grate firing of e.g. refuse, such as municipal solid waste, with a post- treatment of the bottom ash (by means of the reactor) in a single plant, so that the final bottom-ash and/or slag produced will fulfil the current environmental and technical restrictions necessary for reuse, and at the same time this integrated post-treatment provides a less-corrosive flue gas (6), which can be applied to increase the end super- heater (8) steam temperature and thereby the electrical efficiency of the waste-fired boiler of the plant.
  • the total process is integrated, energy-efficient and contained within a single plant without the need for transporting, storing, and subsequent handling/treatment of the bottom ash and/or slag from the grate in another plant.
  • Said less-corrosive gas is essentially free from corrosive components, such as Cl, K, Na, Zn, Pb, whereas the corrosive gas comprises corrosive components, e.g. comprises one or more of Cl, K, Na, Zn and Pb.
  • less-corrosive gas can be understood as gases that provide less corrosion on the end superheater.
  • the reactor is fired from the right-hand side with a secondary fuel (18).
  • the firing does not follow the direction of the transport of refuse in the reactor, and as a result the less-corrosive gas flow as the output from said reactor is counter current, as indicated with the arrow 6.
  • the reactor is located at the end of the transportation direction of the refuse, which is discharged directly from the grate into the reactor.
  • the firing of the reactor can take place by means of a burner (19), which can be fired with said secondary fuel (18), i.e. the burner can be fired with any combination of oil, gas, coal, biomass, air and a selected waste or refuse fraction.
  • said secondary fuel in addition, or as an alternative, is supplied directly to the reactor instead. Since the reactor is fired, it reaches a higher temperature as compared to a reactor with no firing. This heat is needed to burn out the volatiles and to sinter the waste slag, trace and heavy metal species. This can be considered as a post-treatment process, i.e. the boiler or waste incinerator is combined with the reactor.

Abstract

Chaudière (1) séchant, allumant et brûlant des déchets et produisant de la vapeur (2, 2a) par échange thermique avec des gaz de combustion (3). Ladite chaudière (1 ) comprend un réacteur (16) avec allumage de combustible secondaire (18) produisant un flux de gaz moins corrosif (6), et un surchauffeur terminal (8) se trouvant dans le flux (6) de ce gaz. Ledit réacteur (16) pourrait être un réacteur de frittage, un four rotatif, un lit fluidisé ou un lit avec giclage. Il en résulte une durée de vie accrue pour le surchauffeur, et la chaudière décrite assure une production énergétique élevée et efficace.
