The post How a Sequenced Changeover Approach for a Plant Upgrade Minimizes Downtime first appeared on the ISA Interchange blog site.
With the help of a consulting engineering firm and system integrator, a major Midwest steel producer successfully upgraded the main blast furnace and stove control system with no interruption in overall blast furnace or stove control system operations. The challenge was to create a transition plan and minimal-risk implementation (with no impact to production or […]
The post AutoQuiz: What Is the Standard for Embedded Software for a SIL 3 Certified Safety System? first appeared on the ISA Interchange blog site.
Today’s automation industry quiz question comes from the ISA Certified Automation Professional certification program. ISA CAP certification provides a non-biased, third-party, objective assessment and confirmation of an automation professional’s skills.

The post Applications of Thermoelectric Modules on Heat Flow Detection first appeared on the ISA Interchange blog site.
Abstract: This paper presents quantitative analysis and practical scenarios of implementation of the thermoelectric module for heat flow detection. Mathematical models of the thermoelectric effects are derived to describe the heat flow from/to the detected media. It is observed that the amount of the heat flow through the thermoelectric module proportionally induces the conduction heat owing […]
The post What Are the Benefits of Oxygen-Based Fuel Controllers for Biomass Plants first appeared on the ISA Interchange blog site.
Fuel delivery is a common problem in biomass plants. Wood fuel is not uniform in shape, density, moisture content, ash content, or energy content. In plants operating in manual mode, an operator makes a fuel adjustment every 5 minutes. More often than not, the adjustment is excessive, causing predictable system oscillations, which cause decreased efficiency, […]
