Estimating the term…
According to a process for the combustion of organic substances, such as domestic or industrial waste and the like, in a fluidized incineration bed (1) at a mean combustion temperature of 800.degree. C., the flue gased emitted by the fluidized bed (1) are heated with the associated flue dust to a temperature of at least 900.degree. C., preferably 1000.degree. C. to 1200.degree. C., in a subsequent combustion zone (23), in order to destroy toxic substances are burnt. To this effect, the flue gases are introduced in the incinerating chamber of an industrial furnace, for example a steam generator (2) of a coal-operated power plant. By connecting in the gas supply line a fluidized bed (1) upstream of a steam generator (2) fired with coal, a substantial reduction in NOx formation is achieved.
Process for the combusion of coal and/or organic substances, like home garbage, industrial refuse and similar matter, utilizing a fluidized bed combustion unit with a medium combustion temperature of approximately 800.degree. C., comprising the step of introducing into a combustion chamber of a steam generator, flue gases exiting from the fluidized bed combustion unit, together with airborne coal dust.
A combustion unit for a power plant comprising an integrated, coal heated steam generator, a fresh air blower, a dust removal device and a device for removal of sulfur from flue gases, and on a gas side of the steam generator, a fluidized bed combustion unit without built-in heat exchange heating surfaces, wherein the fluidized bed combustion unit is connected to the steam generator, and wherein the operating temperature of the fluidized bed combustion unit is regulated by adjusting reaction materials introduced into the fluidized bed.
