Industrial Water Tube Boiler Design: Formulas in Practice

Description

This book consists of steps for the thermal & mechanical design of d-type water tube boilers. It provides the reader with guidance for burner, fan size, and capacity selection, furnace thermal and dimensional design, super heater primary thermal and mechanical design, and boiler bank and economizer design. Calculations of the methods and efficiency are also described.
