fuels such as coal. McDonald's Lime in Otorohanga, New Zealand operate two pulverised coal fired, rotary lime kilns producing burnt and hydrated lime for a variety of customer bases including the gold, steel, roading and water treatment industries. Each kiln uses approximately 100 tonnes of coal per day producing in excess of 400 tonnes of carbon
According to Charles Ophardt, "In the system known as atmospheric fluidized-bed combustion, a turbulent bed of pulverized coal and limestone is suspended by an upward blast of air. The combustion chamber has many boiler tubes which convert water into steam. The turbulent mixing of coal and air allows the combustion to occur at a lower ...
Pulverized Coal Injection for Blast Furnace Used in Ironmaking field The PCI is one of the major measures to considerably reduce the coke ratio and improve indirect reduction. The substitution with cheaper coal for expensive coke can lower the cost of hot metal making.

The unit is rated at 117 MW(e) (net) and is front wall fired with a pulverized bituminous coal blend. The goal of the project was to reduce emissions of NO{sub x} by 60%, from the ``as found`` baseline of 0.98 lb/MBtu (420 mg/MJ), and to reduce emissions of S0{sub 2} by 50%.
Coal combustion products ( CCP 's) are the inorganic residues that remain after pulverized coal is burned. Coarse particles (bottom ash and boiler slag) settle to the bottom of the combustion chamber), and the fine portion (fly ash, fig. 1) is removed from the flue gas by electrostatic precipitators or other gas-scrubbing systems. Figure 1.
