Which type of fuel is commonly used in low-pressure boilers?

Natural gas is commonly used in low-pressure boilers due to several key advantages it offers over other fuel types. It is highly efficient, providing good combustion properties which result in lower emissions of pollutants compared to coal and oil. The combustion of natural gas generates a significant amount of energy with fewer by-products, making it a cleaner alternative, which is particularly important for meeting environmental regulations.

Additionally, natural gas is readily available through existing pipeline infrastructure in many areas, providing a consistent and reliable source of fuel for heating applications in low-pressure boilers. This accessibility often makes it a more economical choice than other fuel types, as it typically has lower costs associated with storage and transportation.

While oil and propane are also used in certain applications, natural gas tends to be the preferred standard for many low-pressure boiler operations, particularly in residential and commercial settings. Coal is less commonly used in low-pressure boiler applications today due to environmental concerns and more stringent regulations around its combustion.
