OxyFuel combustion of Coal and Biomass - DTU Orbit

Additionally, the combustion of a coal/straw blend with a straw share of 50 wt% has added valuable understanding to the trends in ash and deposits chemistry for coal/straw co-firing. Recirculation of untreated flue gas in oxyfuel plants will increase the in-boiler levels of NO and SO2 significantly.

Oxyfuel Technology | The Linde Group

When coal or natural gas is burned with the addition of normal ambient air, a great deal of flue gas is created. These volumes can be reduced by removing the nitrogen present in air upstream from the furnace, leaving only oxygen. Engineers use this principle for the oxyfuel process. Here, coal is combusted with pure oxygen instead of ...

CO2 Reduction by Oxy-Fuel Combustion

CO2 Reduction By Oxy-Fuel Combustion - Summary oxy-fuel firing of coal fired boilers is feasible for CO2 sequestration. Stand alone oxygen generation plant consumes 10 to 20% of the power plant output and is not economically attractive "Oxy-fuel combustion" without producing pure O2 appears promising for CO2 sequestration.

Ignition and combustion of pulverized coal and biomass ...

Oxy-fuel combustion is a 'clean-coal' process that takes place in O2/CO2 environments, which are achieved by removing nitrogen from the intake gases and recirculating large amounts of flue gases to the boiler. Removal of nitrogen from the combustion gases generates a high CO2-content, sequestrationready gas at the boiler effluent.

The project will retrofit oxyfuel technology to one of the Callide A boilers. That involves burning of pulverised coal in a boiler with a mixture of oxygen and recirculated waste gases to create a high concentration of CO2 in the gases exiting the boiler. The CO2 will then be captured, purified and compressed to liquid form.
