Solid Hydrocarbons: Coal, Petcoke or Biomass via gasification process

In the dryfeed process, pulverized coal is transported pneumatically using an inert carrier gas into the gasifier, where it contacts oxygen and steam. To protect against the high gasification temperatures of up to 1600°C, a membrane wall that consists of highpressure water/steam tubes is used. ... High and mediumpressure steam production ...

Carbon Dioxide Capture Approaches |

Postcombustion CO 2 capture is primarily applicable to conventional natural gas and pulverized coalfired (PC) power generation. In a typical PC power plant, fuel is burned with air in a boiler to produce steam, which drives a turbine to generate electricity. The boiler exhaust, or flue gas, consists mostly of nitrogen (N 2 ), and CO 2.

Emissions Advantages of Gasification |

This can be traced to the fundamental difference between gasification and combustion: in combustion, air and fuel are mixed, combusted and then exhausted at near atmospheric pressure, while in gasification oxygen is normally supplied to the gasifiers and just enough fuel is combusted to provide the heat to gasify the rest.

Why pulverised coal is used? Explained by FAQ Blog

At which following process coal is pulverised? In conventional coalfired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C . This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C.

Conversion pulverized coal boiler to burn 100% biomass

100% wood firing would not have the extreme corrosion issues expected with a 50% coal/ 50% wood firing in that latter case the combination of SO2 (from coal) with hi CO ( from unburned wood fuel in upper furnace) leads to high temp liquid phase coal ash corrosion at superheater tubes, but this can be avoided at 100% wood.
