[0079]

[0080] With regard to oxygen carriers, it is preferred that the reaction upon reducing them is endothermic.

[0081] In another preferred embodiment, the oxygen carrier is abrasion resistant.

[0082]In another preferred embodiment, the oxygen carrier is resistant to poisoning by fuel components, including ash and sulfur species.

[0083] Under atmospheric pressure or high pressure, fuel and desulfurization adsorbent are injected into the oxy-combustion fluidized bed combustor using motive gas or buffer gas, which transports fuel and desulfurization adsorption through multiple injectors in the form of air action agent. Motive gas or buffer gas can be in CO 2 Purified carbon dioxide produced in the treatment plant.

[0084] At atmospheric or elevated pressure, oxygen (O 2 ) and mainly carbon dioxide (CO 2 ) composed of recirculated flue gas combined. Will O 2 Mixing with recirculated flue gas is to avoid localized hot spots within the burner; injection of pur...

Abstract

An oxygen fired fluidized bed combustor system (Oxy-FBC) is provided. The system provides means of producing a nearly pure stream of carbon dioxide for storage at high efficiency by controlling the oxygen content within certain regions of the combustor to control the rate of heat release allowing efficient transfer of heat from the combustor to the boiler tubes while avoiding excessively high temperatures that will cause ash melting, and simultaneously remove sulphur from the combustor via sorbents such as limestone and dolomite. The system utilizes a coarse oxygen carrier bed material to distribute heat and oxygen throughout an Oxy-FBC, while injecting fine sulphur sorbent that will continuously be removed from the bed.

Description

technical field [0001] The present invention relates to an oxygen fired fluidized bed combusting system. The system is used to combust fuel to generate heat for applications such as steam and power production, while producing a stream of pure carbon dioxide that can be geologically sequestered, avoiding the introduction of greenhouse gases and pollutants, including sulfur oxides , nitrogen oxides, fine particulate matter and trace elements) are emitted into the atmosphere. The systems and methods disclosed herein incorporate oxygen carriers and sulfur capture to enhance combustion performance. Background technique [0002] CO 2 Increased emissions, such as the burning of fossil fuels, contribute to climate change. Therefore, measures to reduce carbon dioxide emissions are required. Carbon capture and storage (CCS), which can capture up to 90% of carbon dioxide emissions from fossil fuel combustion facilities, has been proposed as a major climate change mitigation technol...
