What type of burners are utilized for small heating and power boilers under 500 kW?

Atmospheric burners are specifically designed for smaller heating and power boilers, typically those with capacities under 500 kW. These burners operate by mixing gas and air in a way that utilizes the natural movement of air and gas flow to achieve combustion. The key advantage of atmospheric burners is their simplicity, efficiency, and relatively low cost, making them an ideal choice for smaller systems.

They rely on the natural draft created by the combustion process, which helps to ensure that the combustion gases are safely vented. The ability to operate with only basic mechanical components makes them easier to maintain and more reliable for smaller-scale operations.

In contrast, gas and oil burners typically require more complex systems to control combustion and handle fuel delivery, while electric burners are less common for applications under 500 kW due to their higher operational costs and typically greater electrical demands.
