Results of experimental investigation of the influence of 
the operating time of a heating surface on the intensity of heat transfer 
in the kerosene and water boiling on it are presented. The experimental 
data on the heat transfer in the indicated liquids boiling on unrun 
heating surfaces have been generalized using different relations.
