Fluidized boiler assembly and method of burning at least two types of fuels in a fluidized boiler

摘要

The fluidized bed boiler assembly (1) comprises: a fluidized bed boiler (1) comprising a combustion chamber, a first conveyor (5) for supplying fuel mixture to the fluidized bed boiler (1) and / or for introducing fuel mixture into the combustion chamber, a first fuel dispenser (12) and a second fuel dispenser (13), wherein the first outlet of the first dispenser (12) and the first outlet of the second dispenser (13) open onto or into the first conveyor (5) side by side or at a distance from each other. A method of simultaneous combustion of at least two types of fuels in a fluidized bed boiler, in which a fluidizing medium is injected into the fluidized bed boiler (1), the first fuel being metered by a first metering device (12) onto or into the first conveyor (5) and transported by the first conveyor (5). ) to the fluidized bed boiler (1), and the second fuel is metered by the second metering device (13) onto or into the first conveyor (5) next to or at a distance from the first fuel supply area, and subsequently the first and second fuels are introduced together into the combustion chamber. boilers (1).
