Adynamic model about the double casing pipes structure of double-face heat transfer is accepted in new type once-through steam generator(OTSG)is established. The model, which can be applied to any steady and dynamic conditions of OSTG in different flowing and heat transferring characteristic, is developed. It provides the bases for the design and operation of control system, analysis and treatment of abnormal conditions and faults, and development of operation rules.
