Building A Culture That Leads To Success

Recent studies show that companies are restructuring their culture, steering away from the competitive work environment with minimal employee recognition, and shifting towards adapting a more team-centric and collaborative working atmosphere.

Nationwide Boiler is proud to say that we have always been a company that encourages team building, and are more than happy to recognize and reward our employees as they excel in their position. In fact, in addition to 5-year length of service awards that are presented at our annual Christmas party, we recognize employees who make a big impact with our ‘Big Kahuna’ award at each quarterly birthday celebration.

IMG_1145.JPGTo encourage camaraderie throughout our company, Nationwide Boiler coordinates multiple events for employees to take part in. This year we have a total of 6 sporting events in the lineup, including soccer, baseball, and college football. The next game we are looking forward to is the Oakland A’s vs. Texas Rangers, and of course, we will be rooting for the A’s! We also coordinate multiple barbeques & dessert socials throughout the year to satisfy our many food lovers and celebrate certain events. Most recently, we held our Independence Day barbeque the week of July 4th. We had grill masters, Larry Day and Michele Tomas, cook up some delicious burgers and hotdogs; while Holly Lepo spoiled us all with her famous and delicious chili, yum! We can’t wait for the next one.

In addition to being sports enthusiasts and foodies, we also like participating and getting in on the action. We recently hosted a bowling lunch at our local bowling alley, Cloverleaf Family Bowl. The group was split into 8 teams (with fun, creative team names), in a competition to win the title of Nationwide Boiler’s 2019 Bowling Champions. In the end, Team Vapor & Team Combustion went head to head, but Team Vapor came out on top. Congratulations to Tim McBride, Phil Blake, Nic Petty, and Sandy Nevels. Let’s see who will take home the title at our next bowling event! 

Nationwide Boiler is blessed to have a team of hard-working, dedicated individuals, which is why we like to create an environment in which they can come to work excited and motivated. Not only does a team focused and collaborative culture increase motivation, it is also proven to improve productivity, encourage creativity, and build trust between employees. And we are living proof of that.

Boiler Basics 101: Common Rental Boilers on the Market

The boiler rental business began over fifty years ago, solving multiple industries’ need for temporary and emergency steam. Nationwide Boiler was at the forefront of the boiler rental industry, starting off with one of the first mobile rental boilers; a 20,000 lb/hr, 300 psig design, O-type package watertube boiler. This boiler was designed for permanent use on a highway-legal open deck trailer, making it a true mobile boiler. This new idea allowed companies to cut capital costs, save time, and be more efficient in their operations. Now, rental boilers are available for small-scale projects to industrial sized applications.

In last month’s edition of Boiler Basics 101, we discussed why rental boilers are a great choice for boiler owners in a variety of industries. To continue the topic, we will now discuss the different types of rental boilers currently on the market.

Trailer-Mounted Boilers

  • - Permanently installed on highway-legal trailers for easy transport by truck
  • - Boilers of various sizes up to 125,000 lb/hr, both saturated and superheated steam
  • - Detachable goosenecks and booster extensions allow for easy removal when space is limited
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Skid-Mounted Boilers

  • - Shop-assembled package boilers, without any true mobility
  • - Available in capacities up to 250,000 lb/hr
  • - Depending on the size of the boiler, skid-mounted boilers can be transported on a flat-bed trailer, step-deck trailer, or by rail
  • - Cranes and/or forklifts typically required for both loading and offloading
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Containerized Mobile Boilers

  • - Typically includes a package firetube boiler, installed inside a container and mounted on a chassis for mobility
  • - Ideal for users who need a boiler-only package that is weatherproofed for outdoor operation in the wintertime
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Mobile Boiler Rooms

  • - Complete steam plants, self-contained within enclosed vans, with all equipment required to produce steam:
  •          * Package firetube boiler
  •          * Atmospheric feedwater system
    •          * Water softener
    •          * Chemical injection tank
    •          * Blowdown separator
  • - Typically available in capacities up to 1,000 hp
  • - Weatherproofed and better suited than alternatives for outdoor operation in the wintertime

Mobile Steam Plants

  • - Similar to a mobile boiler room, with all equipment required to produce steam
  • - Equipment is installed on an open, step-deck trailer
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)

Transportable Steam Plants

    • - Complete steam plant, normally built inside of a standard 20 or 40’ shipping container
    • - Available with either a vertical or a horizontal boiler arrangement depending on requirements
    • - Cranes typically required for both loading and offloading
    • - These systems accommodate less capacity than a mobile boiler room
    • - Popular for overseas and government projects, due to ease of transportation

Each type of rental boiler system explained above has their own unique advantage and may be better fit for one user over another. The requirements of operation, however, are the same: end-users must supply a fuel source (natural gas, #2 oil, propane, or other fuel), electrical power supply, and make-up water. Which type of rental system is best fit for your unique operation?

Nationwide Boiler maintains an inventory inclusive of all types of boilers listed above, ranging in size from 47.5 hp to 200,000 lb/hr. Visit our website to find a complete listing of rental boilers available, and contact a Nationwide Boiler Sales Representative for additional details and pricing. 1-800-227-1966

RENTAL RUNDOWN: WHY USERS NEED RENTAL BOILERS, AND HOW NBI CAN HELP

Established in 1967 by late founder and pioneer Dick Bliss, Nationwide Boiler began with a mission to provide mobile, temporary boilers to steam users during planned and unplanned boiler outages. At the time, our rental fleet wasn’t much of a ‘fleet’ and consisted of just one 20,000 lb/hr trailer-mounted, O-type watertube boiler. Throughout the years, our inventory has grown to consist of over 100 rental boilers and related equipment, all with various specifications and capabilities. And with multiple storage locations throughout the country, we are capable of shipping our boilers to customers not just nationwide, but worldwide.

With a goal of being the #1 emergency boiler supplier, we understand the importance of educating steam users on emergency preparedness and the benefits of utilizing a rental boiler not just during emergencies, but also during planned outages and periods of high demand.

Reasons to Rent a Boiler

  • Unforeseeable Situations
    • -   A boiler shuts down unexpectedly, needing maintenance and/or repairs
    • -   Disasters and natural causes that lead to a temporary steam need

Nationwide Boiler has come to the rescue in many emergency situations. One notable instance was the tragedy on September 11th, 2001, where we responded quickly to assist ConEd with the supply of heat to New York city. 

  • Increase in Demand
    • -   Companies face periods of increased demand due to varying factors, requiring additional steam capacity

Nationwide Boiler has a great deal of experience renting boilers when additional steam is needed. In fact, we have an annual rental with a tomato processing company to support their seasonal increase in demand.

  • Planned Outages or Repairs
    • -   Annual boiler inspections or routine repairs that require a temporary steam source while a facility boiler is taken offline

Nationwide Boiler has over 50 years of experience in providing boilers and related equipment for companies that have planned outages and need temporary steam.

  • Capital Resources
    • -   A company has budgetary restrictions and is unable to invest in a new boiler
    • Nationwide Boiler has a large inventory of 100+ rental boilers. We provide rental programs that are flexible to a company’s budget, and can assist with financing options.

 Whatever the reason for renting a boiler may be, make sure to rent from the best. Nationwide Boiler provides value with reliable equipment and top-notch customer service, and customer needs are always our priority.

Boiler Basics 101: Superheat vs. Saturated Steam

Playing off our last topic, some might argue that there is another boiler type, or classification, to consider. In today’s article, we will discuss the difference between saturated and superheated steam boilers, and the applications that they are most commonly used for.

Let’s begin by talking about the science behind these two types of steam. Simply put, when water is heated to its boiling point, it will begin to vaporize and saturated steam is produced. Superheated steam occurs when the water is continually heated to temperatures beyond the boiling point, without any increase in pressure. Also known as dry steam, superheated steam has a much lower density and produces zero condensate.

As with the other types of boilers previously discussed, saturated and superheated steam boilers each have their own unique advantages and disadvantages and are better geared for certain applications over others. Saturated steam has a high density and is an excellent heating source. Commonly utilized in food processing, sterilization, district heating, and pulp & paper processing, saturated steam has the following advantages: 

  • - Produces fast and even heating due to latent heat transfer
  • - The temperature can quickly be established through the control of pressure
  • - Has a high heat transfer coefficient, which requires a smaller heat transfer surface and in turn, allows for reduced initial
  •   equipment costs

Superheated steam is not typically utilized in heat transfer applications. However, due to its dry composition and ability to cool while remaining in the same physical state, it can be extremely versatile and is most commonly utilized in refineries, for generating electricity, and for powering turbines.

Superheated steam is ideal for powering turbines for the following reasons:

  • - The dry steam allows for steam-driven equipment to function effectively and efficiently (while condensate from wet steam
  •   would negatively affect performance of the equipment)
  • - Improves thermal efficiency and work capabilities of turbines
  • - Contains zero condensate, minimizing the risk of corrosion and erosion damage

With a low heat transfer coefficient that is equivalent to that of air, superheated steam has more energy and can work harder than saturated steam, but the heat content is less useful. In addition, boilers that are built to produce superheated steam require more expensive components on the boiler system, in comparison to a saturated steam boiler. Therefore, it is extremely important to do your homework ahead of time to determine which type of steam is best suited for your particular application.

Did you know that Nationwide Boiler maintains a fleet of both saturated and superheated steam boilers for rent and for sale? In fact, we own the World’s Largest 125,000 lb/hr saturated steam mobile boiler, and the World’s Largest 110,000 lb/hr superheated steam mobile boiler!  Visit our website at nationwideboiler.com to learn more.
