석탄화력 발전용 순환유동층 보일러 내 고온 증기부 운전의 동특성 이해와 응용

다국어 초록 (Multilingual Abstract)

In a thermal plant for power generation, transient behavior caused by load changes is largely controlled by a firing rate of fuel and a feeding rate of water. Different time constants in the boiler system which is composed of the complex configuration of heating surfaces lead considerable response time. The CFB boiler is one of the alternatives for environmental regulations aimed at controlling air emissions at coal-fired power plants. According to the previous presentation results associated with air/gas side in the CFB furnace, this paper reports dynamic simulation and analysis results for thermal process design of water/steam side in the back-pass part of the CFB boiler. The deviation between simulated results and design values is acceptable in engineering application. Finally, the CFB boiler module will be connected on the computational domain of our own dynamic plant simulation tool. It may provide strong support for the furnace and back-pass design in ultra-supercritical CFB boiler system ultimately.
