    The Pros and Cons of Coal Gasification

    -05-02 1 The heart of gasification lies in (shocker) the gasifier, which takes coal, water and air and applies heat under high pressure to make "syngas"-a mixture of carbon monoxide and hydrogenCoal companies are using Air Products Syngas Solutions Solids Gasification Technology to convert coal to syngas for the production of high-value products and clean power The technology can handle high-ash coal and provides an alternative to the costly transport or relatively high-emissions burning of coal Companies can also take advantage of petcoke and biomass opportuniti.

    What is Plasma Gasification and what are the advantages ,Environmental Benefits

    Plasma gasification is a process which converts organic matter into synthetic gas, electricity, and slag using plasma Inside the gasifier, the hot gases from the plasma torch or arc contact the feedstock, such as municipal solid waste, auto shredder wastes, medical waste, biomass or hazardous waste, heating it to more than 3,000 degrees .A further benefit of gasification compared to the use of coal or direct-fired hog fuel boilers is the reduced particulate matter that exits the boiler entrained in the flue gas In certain cases, an ESP is not required to clean the flue gases from boilers fired with syngas.
