BLOG ON INDUSTRIAL HEAT EXCHANGERS
The BOIXAC blog is a technical space specialized in industrial heat exchangers, designed for professionals seeking practical knowledge for demanding thermal processes. Here, we share content on industry updates, regulations, design criteria, energy optimization, and real-world industrial applications.
We analyze how heat exchangers operate in cooling processes, energy recovery, and the treatment of gases, liquids, and bulk solids, delivering efficiency, sustainability, and operational reliability. The content is tailored to help process engineers, plant managers, EPC contractors, and OEMs make informed decisions based on technical expertise and real use cases.
From practical guides to industry trends, this blog is a trusted resource for optimizing thermal performance in industrial processes and integrating advanced heat exchange solutions.

The economiser is the component that converts the residual heat from boiler exhaust gases into a measurable reduction in fuel consumption. This guide analyses its operation, constructive types, main industrial applications and the technical parameters that determine its selection.
Questions and answers
We provide answers to the main questions about heat exchangers, all just a click away.
Energize your heat
BOIXAC is interviewed on the technical outreach podcast, Con G, to talk about industrial heat recovery.
Heat exchangers in the paper industry
We focus on the processes of the paper industry and our contribution through BOIXAC heat exchangers.
What is a Heat Recovery Steam Generator?
Heat Recovery Steam Generator (HRSG) systems depend on the quality of their heat transfer components. This guide analyses the role of economisers and heat exchangers in optimising these systems, the determining design parameters and the selection criteria for demanding industrial applications.
Thermodynamics in nature
We observe the nature and how the forms of heat exchange such as radiation, convection and conduction are applied.
