Choosing one of the different types of boilers for your facility can be confusing. It's important to understand each of the different types of systems as well as their pros and cons. Fortunately, you don't have to go at it alone.
The experts at Applied Technologies of New York offer decades of experience helping pharmaceutical firms, universities and educational facilities, hospitals and medical facilities, hotel and lodging facilities, and large residential properties.
Our factory-trained technician and sales engineers will guide you through the process to ensure you make the most intelligible decision. In the meantime, use the following information to for an overview of the different types of boilers.
If your facility has hot water applications, high-pressure steam applications, or low-pressure steam applications, you may able to utilize a non-condensing firetube boiler. Firetube boilers are commonly used for applications ranging from 51 up to 2,200 horsepower.
These types of boilers use a cylindrical vessel with the combustion gases inside of the tubes and the flame located in the furnace. In addition to housing the tubes and furnace, the vessel also houses the steam and water. Firetube boilers achieve optimal efficiency when the burner, boiler, and control scheme are engineered and designed to function as an integrated system.
Wetback Design vs Dryback Design
Firetube boilers can be purchased in either a wetback or dryback design. In the wetback design, the boiler has a water-cooled turnaround chamber used to funnel flue gases from the furnace into the tube banks.
The dryback boiler design features a larger and swingable refractory-lined rear door integrated with the vessel. This door is used to direct gases for combustion from the furnace into several tube banks. In general, the wetback design needs significantly less refractory maintenance. However, tube removal and cleaning can be much more difficult.
The watertube boiler produces hot water or steam for industrial or commercial applications. Watertube types of boilers are extensively used for comfort heating applications. With this type of boiler, tubes house water and/or steam. At the same time, the combustion products are circulated through the tubes.
In most instances, the watertube design includes several drums. The lower mud drum and upper steam drum are connected by tubes that form the furnace area and convection section. These systems have a BTU input ranging anywhere from 500,000 to over 20,000,000. As a result, watertube boilers are able to provide exceptionally fast steam capabilities and fast response to changing demands due to the relatively low water content.
Industrial Watertube Boiler
Industrial watertube boilers are mainly steam boilers used for a wide array of applications requiring large amounts of steam and higher pressures. These types of boilers have the ability to provide extra heat through the use of superheaters that are integrally mounted.
Commercial boilers are designed with a firetube, small water tube, and electric resistance. They work ideally for universities, libraries, office buildings, schools, laundries, hospitals, and other similar facilities,
Among the different types of boilers, commercial boilers are some of the most diverse. These units can use propane, natural gas, non-fueled electric only, or light oil to provide hot water or steam for process requirements or comfort heating. Based on the commercial boiler selected and application, these systems boast a fuel efficiency as high as 99%.
Essentially, condensing boilers are water heaters fueled by oil or gas. These units can achieve an exceptionally high level of thermal efficiency up to 98%. This high level of efficiency is achieved through the condensing of water vapor in the exhaust gases.
With the condensing design, the boiler recovers a portion of the latent heat of vaporization, which would otherwise be wasted. Most models boast efficiencies over 90% when the temperature of the return water is at or below 110 ºF. As the temperature of the return water decreases, your efficiency gain will increase.
Most notably, electric boilers are known for being quiet, clean, compact, and easy to install. Without combustion considerations, these types of boilers have no exhaust stack, no fuel handling equipment, and no fuels, which means they have minimal complexity.
Among the different types of boilers, electric units are ideally the perfect solution for overcoming stringent low NOx and emissions regulations. Clients choose electric boilers in areas where the cost of electricity is favorable. These boilers range anywhere from 9kW up to 3,375 kW output.
Electrode Types of Boilers
One of the different types of electric boilers are electrode-type boilers. These units utilize water to generate steam and carry electrical current. With this type of system, electric current is transferred through water, which converts it into steam or hot water. Electrode-type boilers can achieve almost 100% efficiency.
