Project Description
Project Description:		CANMET CO2 Consortium-O2/CO2 Recycle Combustion
Project Background:		Project is supported through IEA Greenhouse Gas Task. The project will perform experimental and modeling work; the two interacting with each other. The experimental work is used to initially extract the main features of a coal flame at high O2 and CO2 concentration. It is done on an instrumented pilot-scale process; a down-fired vertical combustor (cylindrical) with a rated firing capacity of up to 0.3 MW and can burn solid; gaseous and liquid fuels. The flue gas can be recycled in the combustor thereby icnreasing the concentration of the CO2 in the gas stream and it uses oxygen either separately or mixed with air for the combustion oxidant.
Project Accomplishments: [NOTE: Updated information not available beginning 2004]		07-Jan-02: Accomplishment: Phase 5 completion Description: Matrix of combustion trials -generate data for optimizing O2/CO2 burner conditions needed to retrofit natural gas and pc fired processes Evaluate performance of CHX (removal of S,Hg,moisture, and superfine flyash) Develop oxygen enhanced firing techniques that are retrofittable Integration of promising air pollution control strategy Advanced process simulation work O2/CO2 burner development The combustion and related emissions trials conducted under Phase 5 demonstrated that: a) The two burner designs provided stable combustion, essentially complete fuel burnout and low NO levels while burning natural gas, EB coal and WS coal with air, O2-enriched air or O2/CO2/FGR mixtures at nominal excess O2 levels of 2%. The furnace conditions for air and recycle combustion were comparable. b) The NO levels from natural gas were zero with O2/CO2/FGR combustion. The highest NO levels were produced with O2-enriched air. c) Axially injected coal resulted in lower NO levels than tangentially injected coal for a given oxidant, with the lowest NO levels being generated by O2/CO2/FGR combustion. d) Virtually the entire sulfur and most of the oxidized mercury was removed from the flue gas by the sodium carbonate sorbent in the CHX®. Elemental mercury comprising 20% of the total input was unabated. e) Preliminary bench-scale screening tests have indicated that up to 70% of the elemental mercury in flue gas may be removed in the CHX® using a solution of H2O2 with a ferric salt catalyst. f) Mass balances across the VCRF for sulfur and mercury yielded closures of about 86% for both elements. Priority trace elements including mercury tended to accumulate in ash between the furnace exit and the main heat exchanger exit and in the first hopper of the ESP.
