METHOD APPLICABLE TO CONTINUOUS STEAM GENERATOR, AND STEAM GENERATOR NEEDED FOR APPLYING SAME

摘要

PURPOSE: A method is provided a continuous steam generator to use method and operation method of a continuous steam generator which has a great friction pressure loss and a high degree of efficiency in refrigeration term of evaporating tube. CONSTITUTION: A steam generator operating method has a flow medium fed through vertical pipes enclosing a combustion chamber, with the mass flow-rate (m) of the flow medium defined by a given equation in terms of the outer dia. of the pipes, their wall thickness, the permissible max. temp. of the pipe material and the heat flow density (q). Pref. the max. permissible temp. is calculated from a given equation in terms of the critical temp.corresponding to the temp. of the flow medium at a critical pressure, the permissible stress, the thermic expansion coefficient and the elasticity modulus of the pipe material.
