What characterizes a dual-fuel boiler?

A dual-fuel boiler is characterized by its ability to utilize two different fuel sources for combustion. This versatility allows the operator to switch between fuels, often to optimize efficiency or response to fuel availability and cost. For instance, a dual-fuel boiler might use natural gas as its primary fuel and switch to oil when gas supply is interrupted or when oil is more economical.

This feature provides significant operational flexibility and can enhance reliability, particularly in industries where consistent steam generation is crucial. The design of dual-fuel systems often includes separate fuel delivery systems and controls to manage combustion processes for each fuel type, ensuring optimal performance under varying conditions.

In contrast to other options, this definition does not relate to renewable energy sources, operational pressures, or specific use cases, focusing instead on fuel capability and the strategic advantages that come with it.
