The plan, which Vattenfall's engineers have decided to call MaxBio, will replace up to 724,000 tons of coal per year, starting in 2018. As a result, it will prevent at least million tons of carbon dioxide from being released into the atmosphere. That corresponds to a 27 percent decrease.

Fig. 1 illustrates the primary components at WAC in a process flow diagram. The plant design is based on the Shell Coal Gasification Process (SCGP) in which pulverized fuel mix is converted to synthesis gas (syngas) under substoichiometric conditions in a dry feed slagging entrained flow gasifier at elevated temperatures between 1500 and 1800 °C.. The gas is subsequently cooled for cleaning ...

The study object is a 35 MWth oxyfuel combustion power plant coalfired boiler, which consists of a medium temperature and medium pressure boiler (main specifications in Table 1), ASU and flue gas purification system (FGP). The cold wet and cold dry recycle mode could be realized by selecting the location of recycled flue gas (shown in Fig. 1).

Bituminous. The next stage of coal is hard and a shiny, smooth black color, with a high Btu rating. It also contains a sticky substance known as bitumen, which is used when making asphalt, but this sticky coal makes it tricky to undergo coal drying processes before being burned. Much of this coal is used for energy production as it does not ...

This involves the simultaneous milling and drying of raw coal immediately before combustion in a beatertype mill, aerated by the hot flue gas drawn off at 900 1000°C from the upper levels of the furnace chamber. Such predrying requires a boiler substantially larger to cope with the large quantity of evaporated water.
