Modeling of fire-tube boilers - ScienceDirect

Highlights A dynamic model has been developed for the analysis of boiler performance. The mathematical model is based on the first principles. The model gives the dynamic performance during nominal operation and the start-up. The model proposed is useful to assist plant engineers and for training operators. A case study of an 800 HP fire-tube boiler was simulated using pulse and step …
