Gasification as incomplete combustion Gasification is most simply thought of as choked combustion or incomplete combustion It is burning solid fuels like wood or coal without enough air to complete combustion, so the output gas still has combustion potential The unburned gas is then piped away to burn elsewhere as needed Gas produced by this method goes by a variety of names wood gas ....

Coal gasification The term coal gasification refers to any process by which coal is converted into some gaseous form that can then be burned as a fuel Coal gasification technology was relatively well known before World War II, but it fell out of favor after the war because of the low cost of oil and natural gas Source for information on Coal Gasification Environmental Encyclopedia dictionary...

Slag and Ash As discussed in the Background, solid waste from conventional pulverized coal-fired power plants is a significant environmental issue due to the large quantities produced, chiefly of coal fly ash, and the potential for leaching of toxic substances eg heavy metals such as lead and arsenic into the soil and groundwater at disposal sites, and accidental releases from coal ash ponds...

May 02, 2009 0183 32 Pennsylvania hopes to replace many of its filthy coal-fired power plants with IGCC plants You could put a million scrubbers on an old coal-fired power plant and never even approach the environmental performance of a coal gasification plant, says Kathleen McGinty, secretary of Pennsylvania s Department of Environmental Protection...

Aug 29, 2012 0183 32 Coal gasification is said to have greater efficiency than conventional coal-burning because it can effectively use the gases twice the coal gases are first cleansed of impurities and fired in a turbine to generate electricity Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbine-generator...

In addition to the advantages the traditional coal gasification technology has, it also has the following advantages 1 The technology is simple and low cost 2 In the partial gasification process, raw coal containing phosphorus, chlorine, alkali metals, and other pollutants are ,...

Feedstocks enter the gasifier at the top, while steam and oxygen enter from below Any kind of carbon-containing material can be a feedstock, but coal gasification, of course, requires coal A typical gasification plant could use 16,000 tons 14,515 metric tons of lignite, a brownish type of coal, daily...

the challenges and benefits of coal gasification process aUtoMation T he United States has enough coal to provide energy for the next 200 years with a recoverable reserve base of nearly 475 billion tons With oil prices continuously rising and unrest in the Middle East, utilizing our coal reserves seems a likely option for the United Stat...

However, I am not clear on whether or not the gasification process itself releases CO2, and, whether or not the volume of coal-per-GWhr used to for these generation plants is higher than you would need for the same MWhrs from a coal plant which would defeat the CO2 savings it seems to me...
