Therefore, fuels are burned with a mixture of CO2-rich recycled flue gas or steam (to act as diluents replacing nitrogen in order to moderate the temperature) in addition to the oxygen from an air separation unit. In the current design of the oxyfuel combustion for pulverised coal fired boilers, the CO2-rich recycled flue gas is used as the diluent. This report will be limited to that design.

Pulverised-fuel ash. This is covered by the British Standard BS 3892: Part 1: 1993 (Specification for pulverised-fuel ash for use with Portland cement). The solid waste product extracted from power station flue gases by electrostatic precipitation is selected and, where necessary, processed. An upper limit is placed on SO 3 level of 2.0 per cent.

The combustion of pulverised fuel in a mixture of recycled flue gas (RFG) and oxygen, however, presents new challenges to combustion specialists. Several experimental investigations with oxy-firing pulverised coal burners report that flame temperature and stability are strongly affected [1–5] 1 2 3 4 5 .

Fuel blending can achieve desired characteristics that can be effectively and successfully fired in PC boilers. Furthermore, the use of lower-quality fuels such as PRB coals or opportunity fuels such as petroleum coke or biomass fuels has been successfully demonstrated. In PC firing, attention must be given to particle size and its consequence ...

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
