Commercial Boiler Industry

Today’s industrial companies are moving more of their manufacturing operations into automation and robotics — with new facilities and production lines designed to maximize space, as well as to reduce production time and labor costs. To meet this demand, the Commercial Boiler Industry is responding to thousands of companies who are moving to more technically advanced facilities or making the changes necessary to introduce the newer technologies in current plants.

Boilers are a key component of every heating system that provides warmth throughout entire manufacturing facilities. It is estimated that more than 60,000 industrial boilers exist in the US today with thousands of them needing to be updated. This need combined with the onslaught of automation and robotic manufacturing applications indicates the future holds many opportunities for the boiler manufacturing industry.

In this issue of EVERYTHING UNDER CONTROL, we will talk about the basics of what commercial boilers are, how they operate, and how new technology will affect the industry.

Industrial Boilers Today and Tomorrow

Industrial boilers are used by all manufacturing industries — including automotive, major appliances, food and beverage, petrochemical, power, chemical, and many more. Commercial office and multi-family buildings often use boilers for heating as well.

There are two types of boilers — one that produces hot water and one that produces steam, which is then used to carry out the heating process. The hot water or steam produced is transferred to all areas of the plant or commercial facility through a custom designed piping system.

In order to heat the water or produce the steam, boilers use different types of fuels — including both fossil and non-fossil — as well as biomass, which is carbon-based materials contained in living organisms. The water or steam enters radiators or other components that then disperse the heat needed to keep indoor spaces comfortable. Natural gas is the most common fuel used in commercial boilers. There are also other kinds of boilers available that burn fuel oil or use electric resistance coils to produce heating from electricity.

Boiler Room

Some reported studies indicate that the US commercial boiler market is on pace to reach more than $1.5 billion by 2024 — and is expected to expand at a compound annual growth rate (CAGR) of nearly 5.0% from 2021 to 2028. The rapid move to automation and robotics throughout the manufacturing sector is expected to drive this growth in the US and global markets.

Many new boilers will be designed and manufactured to meet the needs of these companies that are moving manufacturing operations to more technically advanced facilities or making the changes necessary to introduce the newer technologies in current plants. In addition, there will be thousands of current boilers that will need to be replaced or upgraded with new technology as well.

Keeping the right amount of extra air in a boiler is important for it to run well and efficiently. When fuel mixes with the right amount of air, it burns better, creating more heat and wasting less energy.

If there’s not enough air, the fuel doesn’t burn completely, which wastes fuel and can produce harmful gases. But if there’s too much air, it cools the system and makes it less efficient. Tools like oxygen sensors help control the air levels, so the boiler runs safely, smoothly, and saves money.

Innovative Boiler Industry Trends

During the past decade, a wide variety of innovative boiler industry trends have emerged at a rapid pace. As the demand for low NOx (Nitrogen Oxide) performance systems, higher efficiency units, and reduced carbon footprints increases, companies have access to the most cutting-edge and advanced systems ever designed with more innovations to come.

Advantages of Low-Mass Boilers

Low-mass boilers have many advantages over older, high-mass ones. One big benefit is that they heat up much faster. Traditional boilers take a lot of time and fuel to reach the right temperature, but low-mass boilers warm up quickly—saving energy and money.

They can also turn on and off more easily without needing to stay hot all the time. This helps reduce energy use when heating isn’t needed and makes each heating cycle more efficient. For places with changing heating needs, like factories or plants, low-mass boilers offer better control and lower costs.

Low NOx Boilers

Newly emerging low NOx regulations are designed to reduce the harmful effects of Nitrogen Oxide (NOx) gases on the environment. These reactive highly toxic gases are produced when fuel is combusted at high temperatures, such as with water heaters, boilers and furnaces.

Because of the harmful effects of NOx on the environment, a growing number of boiler manufacturers are working to get prepared for the coming regulations. In addition to lowered NOx and carbon monoxide emissions, the benefits of low NOx burners also include increased energy efficiency, improved product quality, reduced maintenance costs, and greater return on investment.

Commercial Water Equipment

Packaged Skid Solution

A growing trend in process heating is the installation of ‘point-of-use’ steam or hot water generation equipment. In contrast to the central plant method, a smaller boiler system can deliver the needed energy transfer right at the process location. These smaller steam or hot water systems, often referred to as packaged skid solutions, are self-contained boiler plants.

A packaged boiler skid consists of a boiler, or multiple boilers, and the requisite accessories to complete steam or hot water generation and distribution. All essential equipment is packaged on a common skid base and is prepiped and wired during the manufacturing process at the builder’s facility, eliminating the need to perform these tasks at installation.

Many times, lengthy distribution piping in large facilities results in lost energy due to pressure drop, as well as radiation and convection losses. The self-contained, packaged boiler skid minimizes or eliminates this lengthy distribution and return piping or pumping requirements.

Another advantage of a packaged boiler skid is the ability to size the boiler system to match any specific process load. Many times, the compact footprint enables boiler plants to be located right on the factory floor. Facility owners may benefit from the flexibility and reduced capital investment provided by point-of-use boiler systems.

Advantages of Modular Boiler Systems in Variable-Load Commercial Buildings

In places where heating needs change during the day or across seasons, modular boiler systems are a smart option. Instead of using one large boiler all the time, these systems use several smaller boilers that turn on only when needed. This helps match energy use to the building’s actual demand.

These smaller boilers can start and stop based on what's required. When demand is low, some boilers can stay off, which saves energy and avoids wear and tear. Each working boiler runs more efficiently, helping reduce energy bills and extend the system’s life.

For businesses like offices, hotels, or factories, where heating needs can change often, modular boilers make it easier to manage heating while keeping things reliable and cost-effective.

Plug-and-Play Boiler Installation

No longer are commercial boilers mammoth in size and made of cast iron. Many of today’s slimmer, more flexible, smaller units can be installed and transported with minimal effort. The mere compact size of today’s condensing boilers makes them easier to install, but many manufacturers are going a step further to make installation as simple as plug-and-play. Features like integrated low-loss headers work to streamline installation by significantly reducing the time required for system piping.

Blowdown Systems

Today, boiler efficiency includes discussing water quality which can also have a critical impact on the lifespan of the hydronic system. As a result, manufacturers are beginning to focus more on packaged solutions that include blowdown systems that intentionally wastes water from a boiler to avoid the concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler.

Water Quality Treatment

Water softener treatment systems eliminate scaling from forming in process equipment piping, as well as heat exchange systems. These solutions are also an effective way to bolster the effectiveness of rinsing and cleaning processes. Smaller boilers have narrower waterways and are more likely to become clogged or blocked with a combination of scale and magnetite. Blockages may affect the heat exchangers and circulators while coating the inner surface of the iron piping. Builders and installers are turning to the addition of water softener treatment systems as one of the steps taken to protect the health of the system by preventing buildup over time.

Annual Cleaning and Maintenance

In addition to ongoing water treatment, it’s essential to ensure both the waterside and fireside surfaces of the boiler are cleaned annually. Regular cleaning not only helps prolong boiler life, but also increases overall efficiency. By attending to both water quality and scheduled maintenance, operators can significantly reduce the risk of costly repairs, system downtime, and premature equipment failure.

Commercial Boiler Industry

Industrial Internet of Things

The Industrial Internet of Things (IIoT) has impacted virtually every industry around the world and the boiler industry is no exception. Many boilers now offer some form of Wi-Fi capability with the ability to control the unit from virtually anywhere through an internet connection. The boiler industry can expect to see more progress in this area in the coming years. Companies will increasingly gain the ability to control and monitor their boiler from apps on their devices. Boiler manufacturers have also begun to use the IIoT to research new components to ensure customers have the most up to date systems available.

Remote Monitoring

Remote monitoring provides an opportunity for users to be in control of their boiler 24 hours a day, even if they are not physically on-site. This technology has evolved over the years and today remote monitoring can be accomplished using any internet connected device. With the implementation of data-driven modems, many cybersecurity concerns associated with boiler management systems (BMS) being connected via the client’s server have been widely overcome.

Beyond convenience, remote monitoring capability is invaluable for managing boiler operation and detecting any malfunctions on time. Early detection of issues allows facilities to address problems before they escalate, minimizing downtime and protecting critical infrastructure. As remote monitoring tools become more sophisticated, they provide real-time alerts and detailed performance analytics, empowering facilities managers and technicians to make informed decisions and maintain optimal system efficiency.

Online Computing Services

  • Platform as a Service (PaaS) is a category of cloud computing services that allows companies to provision, instantiate, run and manage a modular bundle comprising a computing platform and one or more applications. This can be accomplished without the complexity of building and maintaining the infrastructure typically associated with developing and launching the application(s) — and to allow developers to create, develop and package such software bundles.
  • Software as a Service (SaaS) is a software distribution and licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. SaaS is sometimes referred to as “on-demand software.” A service provider gives customers access through the internet to applications that are developed and owned by the provider. This service allows each user to access programs via the internet instead of having to install the software on the user’s computer. Using SaaS gives users a greater degree of control and knowledge over their project and results in a more efficient and accurate system.
  • Optimum Start Control is keeping the right amount of extra air in a boiler is important for it to run well and efficiently.
