Alberta Boilers Safety Association (ABSA) Practice Test

The use of electricity or natural gas to operate larger boilers is common because these energy sources provide a reliable and consistent means of generating the heat necessary for efficient boiler operation.

Electricity is widely used in many industrial applications for powering pumps, controls, and other mechanical components that support the boiler's operation. Additionally, electric boilers can offer quick response times and precise control over heating, making them suitable for various commercial and industrial needs.

Natural gas, on the other hand, is favored for its high energy content and efficiency in generating heat. Many larger boilers are designed to burn natural gas, which allows for effective heating with lower emissions compared to other fossil fuels. The infrastructure for natural gas is also well-established in many regions, making it a practical choice for large-scale boiler operations.

In contrast, using solar energy may not provide the immediate and consistent heat output required by larger boilers due to its dependence on sunlight and weather conditions. Batteries offer an energy source, but their storage capacity may be insufficient for the scale of energy required by large boilers. Hydropower, while a renewable energy source, typically involves a significant infrastructure setup and may not be directly linked to the functioning of most industrial boilers.
