  • Process and apparatus for burning coal instead of oil
    Patent number: 8250996
    Abstract: The present invention provides a process for burning coal instead of oil comprising the stages of coal gasification, gas combustion and optionally gas purification, utilization of residual heat of flue gas and flue gas discharge. The present invention further provides an apparatus for burning coal instead of oil. By present invention, the fuel cost for an oil-burning apparatus can be reduced by about four-fifths, so the resources of oil and natural gas can be saved either. Furthermore, the present invention has the advantages such as good reliability, high heat efficiency, high level of automation, high return on investment and good environmental benefits.

  • Process for reducing sulphur dioxide emission from burning coal containing sulphur
    Patent number: 5049163
    Abstract: This invention discloses a process for reducing sulphur dioxide emission from burning coal containing sulphur. In the disclosed process, pulverized combustible materials, such as coal, wood flour, combustible plant, charcoal, etc., and a sulphur trapping agent composition are mixed homogeneously to form an admixture which is ground to powder with dimension from about 30 mesh to about 60 mesh. With an improved roll briquetter of the present invention, briquettes with a microporous surface layer of said admixture powder can be prepared. In such briquettes, the atomic ratio of calcium in the sulphur trapping agent composition to sulphur in the pulverized coal is within the range of from about 1.0 to about 2.0. Microporous pellets of said admixture having opening-porosity are also prepared with conventional roll briquetter. The diameter of the prepared pellets is within the range from about 8 mm to about 20 mm. A layer of said pellets covers the surface of pulverized coal in a burner for combustion.
