    Emission intensity is the greenhouse gas emitted over the life of a generator per unit of electricity generated. Of the currently widely used methods of generating electricity the emission intensity of coal and oil is high, as they emit around 1000g of CO2eq for each kWh generated; natural gas is medium emission intensity at around 500g CO2eq per kWh; and all other methods are typically low emission …

    ----- 1-8 better than 90% of the SO- emitted by coal combustion. Carbon-bearing fly ash from the FBM is collected and introduced to the high-temperature CBC where further carbon burnup occurs. As a function of CBC fuel and air rates, temperature and combustion efficiency, FBM bed material circulating through the CBC is regenerated. Three benefits result: (1) A relatively SO_-rich flue gas stream is synthesized …

    Regarding the fluidized bed systems, the bed is filled with an inert bed material. The air is supplied from the bottom of the combustion chamber for the fuel combustion. Provided the air velocity is sufficiently high, the bed and fuel particles are lifted from the bed and are effectively “fluidized.” Two categories of fluidized beds are distinguished: bubbling fluidized bed (or BFB) and CFB. The first one …
