National Board Shares Jurisdiction Regulatory Changes Due to COVID-19

Businesses across the globe are being affected by the current state of the COVID-19 pandemic. Today the National Board posted a supplement to NB-370, The National Board Synopsis of Boiler and Pressure Vessel Laws, Rules and Regulations, which contains temporary changes being made by individual National Board member jurisdictions.

The newly curated webpage provides important and up-to-date policies for installation and inservice inspections, for each jurisdiction that has implemented temporary changes. The database will be updated continually as the crisis evolves.

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. 

Please give us a call at 800-227-1966 if you have an immediate boiler need that can be fulfilled from our stock of brand new boilers, reconditioned boilers, or equipment from our rental fleet.

Boiler Basics 101: What is Steam?

To kick-off our ‘Boiler Basics 101’ series, we are starting at the very beginning. The extremely useful resource, produced by the commercial and industrial boilers that we rent, sell, service and maintain… that resource is steam.

Our business, and the boiler industry as a whole, revolves around steam. We provide boilers and related equipment for both temporary and permanent applications; equipment that works together to produce the valuable resource of steam, utilized in an abundance of processes across many different industries. So, what exactly is steam and what is it used for?

Let’s start with the chemical composition of steam. Water can exist in three physical states; solid, liquid, and vapor. These physical states, in more common terms, are referred to as ice, water, and steam. When water is heated at atmospheric pressure, its temperature rises until it reaches the highest temperature at which water can exist at this pressure. This temperature, 212F or 100C, is the saturation temperature, or boiling point. As water boils and temperature continues to increase, water particles begin to form small bubbles that rise to the surface and vaporize. This is how steam is formed.

Traditionally, steam was associated with locomotives and the Industrial Revolution. However, now steam is an integral part of modern-day technology. Not only is it an excellent source of energy and heat, but it is also sterile, which makes it ideal for use in the food, pharmaceutical, and health industries. Many other industries also utilize steam for processing, petroleum refining, utility and power, and manufacturing.

Steam has become an invaluable part of our world.  Without it, many of the advances and technologies in today’s time would not be as effective or efficient as they are now.

Stay tuned for the next article in our Boiler Basics 101 series to learn about the basic anatomy of a boiler system.

Boiler Basics 101: Basic Anatomy of a Boiler

Boilers are designed to produce steam to accomplish a multitude of tasks; from powering a plant to sterilizing hospital equipment. In simple terms, a boiler is a closed container in which water is heated to its boiling point to produce usable steam. In order to produce steam, there are two key items that must be involved: water and heat.

A boiler is comprised of two seperate systems: the steam-water system (waterside), and the fuel-air-flue system (fireside). As you might have guessed, water is first introduced into the waterside of the boiler. Alternatively, the fireside of the boiler provides heat, produced through the combustion of fuel (commonly natural gas or fuel oil, but can be another source) and air, which is controlled by the burner.  The heat that is created within the fireside is transferred to the waterside to produce steam.

To complete a boiler system, additional elements are required. This typically includes the following major components:

  •  Burner: a mechanical device that supplies the required fuel and air for proper combustion.
  •  Controls: the BMS (burner management system) protects the equipment and personnel from safety issues.
        The CCS (combustion control system) controls the air and fuel for proper combustion.
  •  Fan: supplies air for the combustion to take place.
  •  Water Softener: pre-treats the boiler feedwater for removal of hardness, which would otherwise cause detrimental scale
     inside the boiler system.
  •  Deaerator / Feedwater System: removes oxygen and gases from boiler feedwater supply (which will also damage boiler
    internals), and feeds it to the boiler system via high pressure feedwater pumps.

All of these elements come together to create a robust steam supply system that is utilized in an abundance of processes throughout many different industries. Boilers truly are a work of art, with many pieces working as one system to make something extremely powerful and impactful, which is why we at Nationwide Boiler are so passionate about what we do.
