Title:
酸素分離燃焼装置とその方法
Document Type and Number:
Japanese Patent JP2004516446
Kind Code:
A
Abstract:
An oxygen separation and combustion apparatus such as a boiler or a nitrogen generator in which a plurality of fluid passages and oxygen transport membranes are located within a combustion chamber. The oxygen transport membranes separate oxygen from an oxygen containing gas, thereby to provide the oxygen within the combustion chamber to support combustion of a fuel and thereby to generate heat. The fluid passages are positioned to allow a portion of the heat to be transferred from the combustion to the oxygen transport membranes to heat said oxygen transport membranes to an operational temperature and a further portion of the heat to be transferred from the combustion to the fluid, thereby to heat the fluid and also, to help stabilize the operational temperature of said oxygen transport membranes. Fuel is introduced into the combustion chamber by injection or as a mixture with circulated flue gas. The fuel is introduced into the combustion chamber and the combustion products are discharged so that said combustion products flow in a direction predominantly parallel to said membranes.
