鼓泡床锅炉富氧焚烧含油污泥技术
Oxygen-enriched combustion technology of oil sludge in bubbling fluidized bed
摘要
Abstract
A new type of oily sludge incineration with flue-gas near-zero emissions was put forward.This method uses oxygen-enriched combustion technology to incinerate oily sludge where drying is not required,and CO2 can be recycled to be used in oil field flooding,achieving near-zero CO2 emissions.In this study,oil sludge (200 t · d-1) was incinerated via oxygen-enriched combustion in a fluidized bed,serving as fuel for a boiler.The sys tem was constructed from a conceptual design considering the heating surfaces of dense segments,dilute segments,and the tail section of the boiler.Considering the characteristics of oxygen-enriched combustion and the design principles of a fluidized bed boiler,an oxygen-enriched fluidized bed boiler was designed.The design parameters and structural layout of this fluidized bed boiler are shown in detail.Results indicated that the boiler efficiency of oxygen-enriched combustion of oily sludge can reach 92.59％.Additionally,heat transfer in the furnace was much higher with fluidized bed oxygen enriched combustion.关键词
