An analysis of the temperature distribution in the main drum of a boiler during the process of raising to steam from cold is presented. Recommendations are made for determining the rate of this process in high-pressure drum-type boilers. The main factors limiting further progress in this direction are uneven heating of the main drum, and the resultant stresses. In view of the complexity of the temperature field in the drum during the process of raising steam, it is treated as a resultant of the superposition of two fields: one in the wall thickness and another on the perimeter and length of the drum. The maximum permissible temperature difference in the wall thickness is assumed to be 50 deg C. The temperature distribution in the wall thickness of the drum les considered, and the method of determining the temperature distribution in the ends of the drum is explained. The t~n:odlerc
