Concept of Oxyfuel Combustion

As air contains N2 and Ar by 79%, CO2 concentration in flue gas is

about 15% in combustion with air.

It is possible to condense and recover CO2 directly.

O2

N2 (+Ar)

O2

about 79%

In oxy-fuel combustion, since O2 of purity of about 96-98% which

is separated from air is used, CO2 concentration in flue gas is

Oxyfuel combustion ;

In coal fired power plant, coal combustion by oxygen in stead of air make it possible

to concentrate CO2 more than 90% theoretically in the flue gas.

Applicability and potential ・Applicable to both existing and newly-installed power plants

・Potential for the reduction of cost and auxiliary power by

scaling-up of ASU and the integration of total process

Process ・Installation of air separation unit

・Flame temperature and heat absorption are

adjusted by flue gas recirculation

・NOx emission is remarkably reduced by flue

gas recirculation

・DeNOx will not to be needed and DeSOx will

be compacted in case of new installation

Feature ・CO2 is major component in the flue gas

・The amount of flue gas to CO2 purification can be reduced

to be almost one fifth

Application to Callide A

・IHI is one of pioneers for oxyfuel development starting R&D in 1989, and basic

research and FS were performed in the 1990’s.

・FS of demonstration was performed under the collaboration with Australian partners

after 2004 and demonstration project was started in 2008.

Callide Oxyfuel Project - Objectives

1. Demonstrate a complete oxyfuel process in a retrofit

application

2. Establish the design and operating requirements for large

scale (commercial) retrofit and new-build oxy-fuel plants,

including geological storage

3. Estimate Capital and Operating Expenditures for the next

generation of oxyfuel near zero emission technology plants

4. Demonstrate CO2 storage

Injection and monitoring techniques
