Verify that there is a solid earth ground wire brought to the panel that the Fireye base is mounted to. The failures are usually, though not necessarily, associated with a heavy scale on the tube surface. Among the common methods used to test steam traps are sight, sound, temperature, and conductivity. Corrosion-resistant thermal sprays may also be considered for this application. If combustion is complete, carbon dioxide is produced. The ash characteristics are considered in the boiler design when establishing the size, geometry and materials used in the boiler. Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. If this drops over time, it generally means the flame scanner lens needs to be cleaned, or the pilot assembly serviced. Heres how to do it: If all else fails, call a professional heating technician for help. Please enter the name by which you would like to log-in and be known on this site. The main problem now is that the burners will lock out intermittantly on flame failure.

Unable to process your form submission, please try again later. Since the damage develops over longer periods, tube surfaces tend to develop appearances described as elephant hide, alligator hide or craze cracking. One of the major worries is that incoming electrical power from the utility will fail, be interrupted, or have the wrong current, voltage, or phase. Optimize sootblowing operations to minimize damaging impingement. A thermal imager can show the temperature difference on either side of the valve, indicating a leak. If a boiler flame fails to ignite, or if it extinguishes during operation, the consequences can be severe. Condensate trap plugged. Without neutralizing the acid, it will cause overall thinning of the metal inside a boiler. A shutoff valve may leak through slightly, which will affect system operation. The boiler desk operator immediate action. In this article we will learn about the most common reasons for not starting of boiler. Replace. Identifying and correcting the root cause of tube failures is essential to help lessen the chance of future problems. During normal operation, alloy superheater tubes will experience increasing temperature and strain over the life of the tube until the creep life is expended. Check your gas pressure on high & low firing, and check it while there are any other gas appliances in the building running simultaneously. Solutions: Prevention of scale on the water side of the tubing, as well as tight control of the water chemistry, can help prevent hydrogen damage. Do you have any advice?

Delayed ignition can be caused by a range of problems, including a restricted or weak pilot light. Solutions: For fly ash erosion, distribute flow evenly through the boiler and consider burning a lower ash fuel. Water chemistry upset, such as what can occur from condenser leaks, particularly with salt water cooling medium. Ultimate failure results from rupture due to increasing strain as tube material erodes away. The advantage of infrared cameras is that they can be easily used from the floor of the mechanical room, which avoids the use of catwalks and ladders.
