CONTINUOUS FLOW STEAM GENERATOR WITH A VERTICAL GAS FLUE OF SUBSTANTIALLY VERTICALLY FITTED PIPES. |
摘要 |
<p>A once-through steam generator includes tubes together forming combustion chamber walls and carrying fossil fuel burners. The tubes are frequently provided on their inner surfaces with fins forming a multiple thread and are connected parallel to one another for conducting a coolant flow. According to the invention, the internal tube diameter is a function of a quotient, and points determined by pairs of values of the internal tube diameter and of the quotient lie in a coordinate system between a curve and a straight line. A summated mass throughput of all of the tubes at 100% steam output divided by the circumference of the gas flue in a horizontal section through the combustion chamber is used to form the quotient, and four defined points then lie on the curve which has a steady ascending slope. Application of this configuration is advantageously possible even for once-through steam generators having nominal outputs down to far below 500 MW.</p> |
