Several methods for distinguishing contamination properties of coal at home and abroad have been presented.In order to seek for distinguishing index concerning contamination properties of coal more conformable to real situation of contamination on heating surface of boilers in China,through 200 kW area-dividing test stand concerning contamination of coal ash,the contamination situation on different heating surfaces and the contamination variation in the whole process of combustion have been perfectly simulated.Combined with the results of test,the characteristic parameters reflecting contamination situation in different areas of heating surface have been put forward,determining adoption of the contamination coeficient F1 as basis for distinguishing contamination tendency of coal ash.The result of study can provide reference and basis for design and layout of heating surfaces in boilers.
