Boiler – Fundamentals and Best Practices

A three pass design provides three opportunities for heat transfer. The stack temperature of 3 pass will be lower than that of 2 pass boiler, of the same design and operating pressure. Efficiency is more than two pass boiler. Each pass in boiler should be designed with cross sectional area to achieve optimal flue gas velocity, which in turn
