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

Natural gas is the most commonly used fuel in low-pressure boilers for several reasons. One of the primary advantages of natural gas is its efficiency and cleaner combustion compared to other fossil fuels. It produces fewer emissions of harmful pollutants such as sulfur dioxide and particulate matter, making it a more environmentally friendly option.

Additionally, natural gas systems are typically easier to maintain and operate than those that utilize solid fuels like coal or wood pellets. The infrastructure for distributing natural gas is well-established in many areas, further facilitating its use in boiler systems. This availability, combined with its cost-effectiveness and efficiency, has led to widespread adoption of natural gas in heating applications, including low-pressure boilers.

In consideration of alternatives, while coal can provide a significant amount of heat, its use is declining due to environmental concerns and regulatory issues. Electricity, although a viable option for heating, is generally more expensive and may not provide the same level of efficiency as natural gas when used in boilers. Wood pellets have gained popularity in certain applications, particularly in eco-friendly initiatives, but they are not as commonly used in industrial low-pressure boilers as natural gas.
