Routine Maintenance Reminders

Routine boiler maintenance is imperative not only for safety, but also to sustain efficiency and reliability of your system. Being proactive rather than reactive is likely to increase the longevity of your boiler as well as help prevent incidents that can result in injuries, damage, or worse. Incorporating routine maintenance into your facilities day-to-day operations will prove its worth with a great deal of short- and long-term benefits.

There are certain maintenance tasks that should be performed daily, and others that should be performed periodically. Below we have provided a list of best practices to follow when putting together your routine boiler maintenance plan.

On a daily basis, you should track and keep a log of the following items:

  • Boiler pressure and temperature
  • Stack temperature, to determine operational efficiency (a well-tuned boiler should have a stack temperature range of 50 – 100 degrees above the steam or water temperature)
  • Gas pressure to the regulator, as well as downstream from it
  • Water quality and pH levels, to ensure you are meeting the recommended levels

Blowdown of the boiler (bottom blow) and water column should also be performed on a daily basis. In addition, you should observe boiler and auxiliary equipment daily to ensure proper operation and that there is no damage, leaks, or unusual behavior. 

On a weekly to monthly basis, it’s important to conduct additional visual inspections and observe the operation of certain components for areas that may need to be addressed. This includes:

  • Gauge glass
  • Fuel supply valves
  • Operating and modulating controls, water level controls
  • Flame scanner & burner flame pattern
  • High- and low-pressure switches, combustion air proving switch
  • Indicating lights and alarms

When it comes to the burner, you should inspect the valves, pilot tube, and diffuser thoroughly for any signs of wear that might call for a repair. Also, be sure to observe the entirety of the boiler system for potential hot spots (an indicator of deteriorated refractory) and again, be sure to keep an eye out for any leaks of fuel, water, or flue gas.

Lastly, there are certain items that should be performed on a semi-annual to annual basis. Many of the tasks below can be checked off during the annual inspection, when the boiler is taken offline:

  • Open access doors and inspect the fireside of the boiler
  • Inspect boiler and tubes for evidence of corrosion; clean tubes and tube sheets thoroughly
  • Examine the refractory for large cracks (greater than 1/8”) and patch as necessary
  • Conduct safety tests on the gas valves
  • Review all electrical connections for tightness, signs of wiring wear
  • Check pump alignment on all base-mount pumps

This is also a good time to fully inspect the auxiliaries that provide fuel, air, water, and chemicals to the boiler. In addition, combustion should be reset periodically with the use of a combustion analyzer, for accurate readings of NOx, CO, and O2.

While the guidelines above provide a good baseline of tasks to perform when it comes to routine maintenance, be sure to consider the boiler manufacturer’s recommendations as well.

Air Permitting for Rental Boilers in California

With California having the most stringent emissions requirements in the country, it is important to be well versed on any and all rules and regulations when buying a new boiler or renting a temporary boiler. This is our final installment of the 3-part series on air permit compliance for boilers in California (be sure to check out part 1 and part 2 if you haven’t already).

Nationwide Boiler maintains a fleet of rental units that are sub-9 ppm NOx and pre-permitted for use in the SCAQMD. We take care of the bulk of the permit work saving our customers an exponential amount of time (no waiting for the application to be approved), and we pay for any processing fees. This allows for quick installation and start-up of a temporary boiler, which is extremely valuable in an emergency outage. The only requirement of our customer is the source testing of the equipment, if the source test is due. Most of these pre-permitted boilers require source testing on an annual basis, and the source test must be done at a job site within the county’s jurisdiction.

The SJVAPCD does not allow the pre-permitting of rental boilers, but they do have a program called the Temporary Replacement Emissions Unit (TREU) which can be utilized when a rental is needed  in a pinch. This program contains an application shield provision which allows renters to install a temporary boiler in place of an existing permitted boiler that is down for repairs without having to get a new permit for the rental boiler. In order to qualify for the TREU Program, the rental boiler being installed must have a heat input equal to or less than the unit it is replacing. Plus, it must not have the potential to produce more emissions than the current permit allows. There is a time limitation to this program; the temporary boiler can be on-site for a maximum of 180 days within a 12-month period.

If you are outside of the two territories listed above, don’t fret! Nationwide Boiler can assist with the permitting process as needed. In addition, utilizing a pre-permitted boiler in a location other than the SCAQMD does have its advantages and can help expedite the permitting process.

With our headquarters being located in California, it is important to us that we are up-to-date with emissions regulations throughout the state. And with other areas of the country starting to experience a similar push for emissions reductions, we have the expertise and experience to help. Nationwide Boiler is proud to take the lead in helping customers everywhere understand and comply with current and future air regulation standards.

Ramping Up Our Stock Boiler Program

At Nationwide Boiler, we are known for our relationship with B&W as a partner and stocking distributor. The FM-120-124 B&W D-Type Package Watertube Boiler, also known as our “World Boiler”, is always in stock and has been sold to six of the seven continents in the world. In recent years, we have ramped up our stock boiler program to also include new Superior firetube boilers in a variety of configurations.

To start off, we added two specialized, factory integrated packages. These 47.5 hp and 119 hp skid-mounted package boilers are pre-piped and wired and include a duplex feedwater system and blowdown separator with after-cooler. The 47.5 hp boilers are pre-certified for use in the most stringent California air districts, while the 119 hp packages are PEER compatible for both the SCAQMD and SJVAPCD jurisdictions. Our 475 hp, 150 psi design Superior skid-mounted firetube boiler, equipped with a Webster 7ppm NOx burner, is also ideal for customers in the most stringent areas of California. All three of these systems are currently available from our shop in Fremont, CA. 

To round out our stock inventory of pacakge firetube boilers, we now have the following brand new Superior boilers available for quick ship and immediate needs: 

These stock boilers are pre-built with the burner left purposely un-mounted to allow for greater flexibility in matching the unique fuel, emissions, and combustion needs of each customer. The burner can be quickly mounted prior to delivery or installed at the site, based on customer preference. The boilers are designed for indoor and outdoor applications, with most currently being stored at the manufacturing facility in Hutchison, KS. All units are now available for immediate shipment upon customer request.

We also have our very first, zero emissions electric boiler now available for rent or for sale. This boiler, built to provide 50 hp steam at a design pressure of 150 psig, is another one of our factory integrated units, with feedwater system and blowdown separator pre-piped and wired as a skid-package.

In addition to the new boilers that we purchase specifically for our stocking program, our fleet of rental boilers and auxiliary equipment range in size and in age. We are always open to providing a solution from our rental fleet as well, if the opportunity arises. Be sure to check out or complete inventory of boilers available for sale to find a unit that fits your unique needs.
