In view of the slagging problem occurring in the coal-fired boiler of Guangzhou Power Plant in recent two years for frequent changing the coal species,some reasonable suggestions are put forward sunch as coal blending and slagging mitigration based on technical reformation of the burner according to its combustion equipment structure and combustion test on various proportion of coal species.

8MW hot-water chain boiler into a CWS-fired boiler, the adjustment in combustion and the results of the coal-water fuel combustion test on the retrofitted 2.

In this paper,the design of retrofitting of a 7 MW iol-fired water boiler into aCWF-fired boiler,the modification of operation of CWF system in front of the retrofitted boilerand the results of the coal-water fule combustion test on the retrofitted 7 MW hot-water boilerare briefly introduced.

Analyses the temperature and air flow distribution and smoke flow regularity, and compares the simulation results with the results of combustion experiments.

This essay is aiming at solving the problem of the development of the aerosol cans inspecting instrument of burning test, completing the inspection of export and import aerosol cans by the same standard.
