Jul 25, 2016 To enable Conch Tongling Cement to burn a higher rate of alternative fuels, an integrated gasification system was installed and duly tested. The system converts organic or fossil fuel-derived carbonaceous materials into CO, H and CO 2 and without combustion, produces a fuel that can be used in cement production.

On average, conventional waste-to-energy plants that use mass-burn incineration can convert one ton of MSW to about 550 kilowatt-hours of electricity. With gasification technology, one ton of MSW can be used to produce up to 1,000 kilowatt-hours of electricity, a much more efficient and cleaner way to utilize this source of energy

Jan 01, 2013 Gasification can be described as a three-step process where the first step is dehydration, followed by pyrolysis of volatiles and finally gasification of char. 11 This can be understood by observing the mass loss of a solid material during gasification. Figure 9.2 shows the results of gasification of a wood chip where a small mass loss from dehydration is observed at temperatures below 200C
