The flue gas recirculation device in the conventional circulating fluidized bed (CFB) oxy-fuel combustion system has been taken out and replaced with pure oxygen combustion, which is expected to reduce the overall energy consumption and CO2 capture cost of the unit. Pure oxygen combustion will bring about problems such as uneven distribution of heat load and fluidization difficulty under minimal smoke gas flow, so a new boiler design should be carried out according to the flow pattern and heating surface layout in the furnace. This paper adopts the arrangement of immersed tube heating surface in the dense phase area to solve the local over-temperature problem. At the same time, a unique furnace structure design of "wide at the bottom and narrow at the top", reducing the size of the bed material, increasing the primary air ratio and other methods are used to deal with the difficulties of material fluidization. Based on the CFB flow and heat transfer theory, a heat transfer calculation method of pure oxygen combustion CFB boiler is established, and a conceptual design of 130 t/h ultra-high pressure pure oxygen combustion CFB boiler is completed. The basic structure and overall layout scheme of boiler furnace, immersed evaporating heating tube, immersed superheater, cyclone, loop seal and economizer are given. Preliminary analysis shows that the new pure oxygen combustion CFB boiler can solve the problems of uneven distribution of heat load caused by high oxygen concentration combustion and the difficulty of material fluidization under minimal smoke gas flow. The designed boiler thermal efficiency can reach 94.83%, and the volume fraction of CO2 and H2O in the outlet flue gas is 57.1% and 38.4%, respectively. This paper lays a foundation for the future development of pure oxygen combustion CFB boiler technology and engineering practice for CCUS-EOR.

取消常规循环流化床(CFB)富氧燃烧系统中的烟气再循环装置,转为纯氧燃烧,有望降低机组整体运行能耗和CO2捕集成本。纯氧燃烧将带来热负荷分布不均和极小烟气量下流化困难等问题,因此要针对炉内流态和受热面布置等进行全新锅炉设计。采取在密相区布置埋管受热面解决局部超温问题;同时应用独特的“下宽上窄”炉膛结构设计、降低床料粒度、增大一次风率等方法应对物料流化困难。基于CFB流动和传热理论,建立了纯氧燃烧CFB锅炉传热计算方法,并据此完成了130 t/h超高压纯氧燃烧CFB锅炉的概念性设计,给出了锅炉炉膛、埋管蒸发受热面、埋管过热器、旋风分离器、返料阀及尾部烟道省煤器的基本结构和整体布置方案。分析表明,该新型纯氧燃烧CFB锅炉能够较好解决高氧浓度燃烧带来的热负荷分布不均和极小烟气量下流化困难等问题,设计锅炉热效率可达94.83%,出口烟气中CO2和H2O体积分数分别为57.1%和38.4%,可为未来开发面向碳捕集、利用与封存(CCUS)-强化采油(EOR)的纯氧燃烧CFB锅炉技术和工程实践奠定基础。

取消常规循环流化床(CFB)富氧燃烧系统中的烟气再循环装置,转为纯氧燃烧,有望降低机组整体运行能耗和CO2捕集成本。纯氧燃烧将带来热负荷分布不均和极小烟气量下流化困难等问题,因此要针对炉内流态和受热面布置等进行全新锅炉设计。采取在密相区布置埋管受热面解决局部超温问题;同时应用独特的“下宽上窄”炉膛结构设计、降低床料粒度、增大一次风率等方法应对物料流化困难。基于CFB流动和传热理论,建立了纯氧燃烧CFB锅炉传热计算方法,并据此完成了130 t/h超高压纯氧燃烧CFB锅炉的概念性设计,给出了锅炉炉膛、埋管蒸发受热面、埋管过热器、旋风分离器、返料阀及尾部烟道省煤器的基本结构和整体布置方案。分析表明,该新型纯氧燃烧CFB锅炉能够较好解决高氧浓度燃烧带来的热负荷分布不均和极小烟气量下流化困难等问题,设计锅炉热效率可达94.83%,出口烟气中CO2和H2O体积分数分别为57.1%和38.4%,可为未来开发面向碳捕集、利用与封存(CCUS)-强化采油(EOR)的纯氧燃烧CFB锅炉技术和工程实践奠定基础。

The flue gas recirculation device in the conventional circulating fluidized bed (CFB) oxy-fuel combustion system has been taken out and replaced with pure oxygen combustion, which is expected to reduce the overall energy consumption and CO2 capture cost of the unit. Pure oxygen combustion will bring about problems such as uneven distribution of heat load and fluidization difficulty under minimal smoke gas flow, so a new boiler design should be carried out according to the flow pattern and heating surface layout in the furnace. This paper adopts the arrangement of immersed tube heating surface in the dense phase area to solve the local over-temperature problem. At the same time, a unique furnace structure design of "wide at the bottom and narrow at the top", reducing the size of the bed material, increasing the primary air ratio and other methods are used to deal with the difficulties of material fluidization. Based on the CFB flow and heat transfer theory, a heat transfer calculation method of pure oxygen combustion CFB boiler is established, and a conceptual design of 130 t/h ultra-high pressure pure oxygen combustion CFB boiler is completed. The basic structure and overall layout scheme of boiler furnace, immersed evaporating heating tube, immersed superheater, cyclone, loop seal and economizer are given. Preliminary analysis shows that the new pure oxygen combustion CFB boiler can solve the problems of uneven distribution of heat load caused by high oxygen concentration combustion and the difficulty of material fluidization under minimal smoke gas flow. The designed boiler thermal efficiency can reach 94.83%, and the volume fraction of CO2 and H2O in the outlet flue gas is 57.1% and 38.4%, respectively. This paper lays a foundation for the future development of pure oxygen combustion CFB boiler technology and engineering practice for CCUS-EOR.
