Title:
WASTE INCINERATION FACILITY
Document Type and Number:
WIPO Patent Application WO/2023/223591
Kind Code:
A1
Abstract:
A waste incineration facility (1) comprises: a recirculated exhaust gas line (6) for extracting a portion of exhaust gas flowing through an exhaust gas flow path (4) as recirculated exhaust gas, and supplying the same into an incinerator (3); an oxygen mixing unit (5) for mixing high-concentration oxygen gas having a higher oxygen concentration than air into the recirculated exhaust gas flowing through the recirculated exhaust gas line (6); mixing ratio modifying units (81 to 83) for modifying a mixing ratio of the recirculated exhaust gas and the high-concentration oxygen gas to be supplied into an incinerator (3) from predetermined gas supply positions in the incinerator (3); quantity of interest measuring units (36 to 38) for measuring at least one of an amount of vapor generated by heat of the exhaust gas, a temperature inside the incinerator (3), and an oxygen concentration at an outlet of the incinerator (3), as quantities of interest; and a control unit (10) for controlling the mixing ratio modifying units (81 to 83) such that measured values of the quantities of interest approach predetermined target values. A main gas of a combustion gas supplied into the incinerator (3) via a gas pipe is the recirculated exhaust gas to which the high-concentration oxygen gas has been mixed.
