Systems for controlling Nox from coal combustion

The report provides basic information on different systems to reduce NOx emissions from coal combustion. The systems cover NOx reduction during combustion, by flue gas denitrification and by combined denitrification and desulphurisation. NOx control systems commercially available by various manufacturers and those presently under development by private or governmental research organizations worldwide are included. Each system is presented with the following data: information on the system; process applications; pollution reduction capability. Information on the supplier/manufacturer is also provided in order to assist in obtaining further data if necessary. Each NOx system is described with a process diagram (where available), except for the selective catalytic reduction systems, where only one diagram describing the process is included for reference. The data have been extracted from the IEA Coal Research NOx systems database. The report has worldwide coverage comprising 115 systems for NOx reduction in total. These are 33 combustion systems, 25 selective catalytic reduction systems, 23 catalyst manufacturers, 8 selective non catalytic reduction systems and 26 combined SOx/NOx removal systems.
