What type of pressure is recommended for soot blowers using compressed air?

The appropriate pressure for soot blowers using compressed air is typically in the range of 100-125 psi. This pressure level is effective for ensuring that the soot blowers can adequately clear the accumulated soot from the surfaces of heat exchange equipment such as boilers and economizers. Operating at this pressure provides a good balance between sufficient force to remove soot and the safe operation of the system components.

Using lower pressures, like those in the 50-70 psi or 80-100 psi ranges, may not generate enough force to effectively dislodge soot, leading to reduced efficiency and potential risk of increased temperatures in the boiler, which can cause operational issues. On the other hand, exceeding 125 psi, as seen in the 130-150 psi option, could pose safety risks, such as damaging the soot blower apparatus or causing leaks due to excessive pressure. Therefore, the range of 100-125 psi is recommended as it provides optimal performance while maintaining safety and equipment integrity.
