Advanced combustion zone retrofitting Lidkoeping BFB establishes a state-of-the-art design for waste firing
The oil crisis in 1973 gave an impetus to the development of the fluidized bed combustion technology for power and heat generation with local, often low quality, fuels. Kvaerner delivered the first Bubbling Fluidized Bed (BFB) for Municipal Solid Waste (MSW) firing in 1979 and the first waste fired Circulating Fluidized Bed (CFB) in 1984. Since this introduction Kvaerner has delivered 13 fluidized beds based on MSW out of a total of over 60 BFB and CFB delivers (in the range 5--165 MW{sub ht}). The ever more stringent demands on emissions performance, efficiency and availability have induced a continuous series of design enhancements culminating in the state-of-the-art BFB boilers at Lidkoeping BFB (in operation since 1985 on shredded MSW) was induced by new emission standards and need for increased output. The modified design was based on learning experience from Kvaerner Waste To Energy (WTE) BFB installations and an extensive R and D program. The design has fulfilled all expectations and established a third generation design for MSW fueled BFB-boilers. The green field installation at BCH Energy will commence operation in 1995. Design features include the Advanced Combustion Zone with an air swept fuel inlet spout, an asymmetrical overfire air (OFA) system installed in a double arch arrangement and directional bottom air nozzles. Also included are an integrated ash classifier, an improved back pass surface arrangement and a SNCR-system based on NH{sub 3}.
