At Nationwide Boiler, we consistently evaluate our customers to determine how we can better serve their needs. Most recently, we determined that there is a need for additional Nationwide Boiler rental units on the East Coast, which drove a recent project converting an existing open-trailer unit to an enclosed mobile boiler room. 

Upon inspection of the existing 300 hp mobile steam plant, we found that majority of the equipment, including the boiler, feedwater system, water softener and blowdown separator, was in good condition.  The burner, however, needed to be replaced due to old age. A new Webster low NOx burner was installed on the boiler, capable of firing natural gas or #2 oil with 10:1 turndown. 

Nationwide mechanics decommissioned the 300 hp mobile steam plant, mounted all equipment inside a new container, and piped and wired the system. The complete conversion from mobile steam plant to mobile boiler room, including the new burner install, took just three months to complete.

One advantage of mobile boiler rooms is that no additional structures are required to protect the equipment from rain or freezing temperatures. Mobile boiler rooms are popular during the winter months in the Midwest and in the East where customers experience inclement weather. 

If you are in need of a temporary steam solution, check out our large inventory of mobile boiler rooms.

Every year when winter arrives, Nationwide Boiler takes extra care to inform customers of the importance of protecting their equipment in severe weather conditions. With colder weather, especially temperatures that are freezing and below, extra protection on rental boilers is necessary to avoid operational difficulties and costly repairs.

We have compiled a list of freeze protection recommendations to follow this winter for outdoor installations:

  1. Enclose both the front and rear of the boiler area and use an external heat source.
  2. Utilize an appropriate heat tracing method (electric or steam tracing) to all exposed stagnant water lines, as well as the main lines and piping components. This includes sensing lines (steam drum to CMR, high steam, and steam gauge), auxiliary low water cut-off, water column, level control blowdown, and main continuous blowdown (depending on the length of piping runs).
  3. In addition to heat tracing on stagnant sensing lines, drain the lines and fill them with a 50/50 (water/glycol) solution, making sure to re-connect the line.
  4. When an extended boiler down time is expected, or once the equipment is decommissioned and ready to ship back, completely drain the boiler and stagnant water lines.

Also, keep in mind the following:

  • The lines mentioned above are considered stagnant lines and should be heat traced regardless of whether the boiler is in operation or not.
  • The above are recommendations; use sound engineering judgement calls when there are concerns of possible freeze damage to equipment.
  • The lessee is responsible for all freeze damage to rental equipment, so be sure to care for the equipment properly.

When water freezes, it expands and can damage the boiler lines and piping. Know the correct steps and take precaution when operating boiler equipment in inclement weather.

Nationwide Boiler recently completed production of the world's first 1,000 hp mobile boiler room, designed at 290 psig for a larger range of operating pressures. We are proud of this collaborative effort between Nationwide Boiler and Superior Boiler Works, which came about in response to customer requests for a larger capacity and small footprint.
