Industrial boilers require regular and correct maintenance. When done properly, this maintenance increases safety and reliability and can cut down on the utilization of energy and water. As utility costs continue steadily to rise for commercial and institutional facilities, so do the advantages of preventative maintenance. To take pleasure from the results of any professional boiler maintenance plan, managers should understand the associated costs and benefits.

The first thing to understand is the fact professional boiler maintenance programs feature a price. A manager must consider the benefits as well as the expenses. You can find multiple advantages to implementing this kind of plan. Preventing failures decreases downtime for personnel and decreases costs for replacement parts. An industrial boiler maintenance program can also assist in improving safety and system reliability for your boiler, and help predict maintenance cycles. Most importantly, a maintenance program increases savings from water and energy usage.
In the event the failure rate for system components increases, an commercial boiler maintenance program might cost significantly less than corrective actions. However, corrective costs are difficult to determine because of their unknown nature. Such costs could include lawsuits over failure to keep safety measures. Ultimately, to understand these costs, managers must understand industrial boiler systems and their potential maintenance issues.
The two most common types of fuel-fired boilers are fire-tube and water-tube systems. In fire-tube boilers, hot gases circulate through tubes that are submerged in water. On the other hand, water-tube boilers send hot gases flowing over tubes filled with water. Both systems are being used to create steam and yield similar power, but that’s where the similarities generally end.
Each industrial boiler component can be susceptible to unique maintenance issues, so testing options for them may differ. The U.S. Department of Energy describes maintenance issues, and how to prevent them, in their manual for Operations & Maintenance Best Practices for Boilers. Inside the manual, you can learn various maintenance techniques and many other recommendations once and for all boiler practice. Nearly all these checks are done everyone to four years by contracted professionals who specialize in professional boiler maintenance.
Managers should be well versed in the various the different parts of each commercial boiler and their specific maintenance requirements. Drums will be the most expensive components of boilers, with the most frequent maintenance issue being corrosion. Headers are also vunerable to corrosion and erosion, as well as metal fatigue. Main steam piping often suffers the same damage. Certainly, the largest volume of occurrences of forced downtime for boilers result from tubing failures, that can be susceptible to flow obstructions. Other components to consider when deciding maintenance needs are de-aerators, air openings, feedwater piping, flue-gas vent systems, the pilot, and main burners.
There are many diagnostic techniques a manager should implement that can extend the life span of an professional boiler and increase its efficiency. If the machine is closed-loop, installing meters on make-up water lines helps monitor flow and find leaks. Where possible, an automated surface conductivity blowdown system can be installed to accurately control TDS and optimize energy recovery. Routine checks of the boiler’s chemical make-up and checking insulation on piping and storage tanks are also advised.
Industrial boilers should be turned regularly to optimize performance, which strongly correlates with minimal wear on components. Water tubes and fire tubes should be cleaned and inspected regularly to lessen scaling. It will also be routine to check all safety devices, including pressure controls, pressure switches, scanners, gauge glass, and primary and auxiliary low-water cutoffs.
