Reducing Calcination Energy through Dispersant Optimization

This whitepaper walks through the thermodynamics of water removal in a gypsum board kiln (enthalpy of vaporization of water: 2,257 kJ/kg at 100 °C, NIST), the economics of natural-gas burn per square metre, and the practical realities of pushing a modern PCE system toward deeper water reduction without losing line stability.

Topics covered: - Heat balance framework for a representative board line - PCE chemistry decision tree: short side chain vs long side chain - Coupling with foam stability — where savings can be silently lost - A line-trial protocol structure - A worked energy-saving calculation template (inputs supplied by the plant)

Available on request via the contact form with your line speed and current dispersant chemistry. The document is a framework, not a case study, and requires plant-specific inputs to produce a defensible number.
