In this paper,the author introduced the problems occurred when blending refinery gas in coal-burning boiler,analyzed the causes,put forward countermeasures.

In China,only very few plants implemented low proportion dry gas mixing into coal for burning in fluidized -bed combustion boilers,there is no successful experience and precedent in the high proportion mixing technology.

Pilot study of oil refining wastewater reuse by ozone-biological activated carbon process;

introduced principle and technology of Treating Waste Gas from Incinerator,analyzed the principle of dust removal,HCl removal and denitrification in the waste gas from incinerator,probe into the influencing factors of treatment efficiency on the basis of the experimental result to treat the waste gas from incinerator.
