Abstract: A new method for researching the influence of the soot blower steam parameters on the temperature field and the pressure field near the heatabsorbing surface tube sections was introduced. Taking a certain soot blower as research object, under the certain range of the soot blower steam parameters, the relations between the pressure and the temperature of the soot blower steam and the pressure field and the temperature field near the tube sections of the heatabsorbing surface were analyzed. 

Key words: computational fluid dynamics (CFD), soot blower steam, tube sections of heat-absorbing surface, temperature field, pressure field
