Eligible Technologies

FortisBC offers rebates for steam boilers for four key technologies that can either be factory fitted on a new steam boiler or retrofitted onto an existing steam boiler as an upgrade: 

  • Parallel positioning burner controls
  • Oxygen (O2) trim
  • TDS (conductivity based) automatic blowdown controls
  • Economizers (condensing or non-condensing).

Parallel Positioning

Steam Boiler Rebate Value – $9,000 – $16,000

Parallel positioning (often referred to as “linkage-less” control) is a precise, repeatable method of controlling the flow of fuel and air through a modulating burner. The fuel control valve and air damper are each moved by their own dedicated stepper motor actuators, each of which is electronically controlled by an air-fuel ratio controller. 

On the other hand, a “linkage” burner uses a single servo motor to modulate both the fuel valve and air damper which are mechanically connected together by a series of adjustable jackshafts and linkage arms. The difference is similar to how modern electronic fuel injection systems compare to carburetors in automotive engines.

When air and fuel flow are parallel position systems, so when these elements are accurately controlled, a well-designed burner can be precisely tuned to minimize leftover oxygen in the exhaust throughout the full turndown range. This leftover oxygen in the exhaust is referred to as  “excess air” and is inversely proportional to combustion efficiency. That means that lower excess air means lower fuel consumption. 

There are many factors that can affect the net fuel savings realized by switching to parallel positioning controls. A typical estimate would be 5%, although savings of 15% or more are quite possible in certain circumstances. Linkage-less platforms like the Weishaupt W-FM and Siemens LMV are generally known to be safer, more reliable, and require less maintenance over time than conventional burner controls. 

Between Parallel Position and Oxygen Trim

Oxygen Trim

Steam Boiler Rebate Value -$16,000 – $18,000

Oxygen trim is an additional control feature that works in conjunction with parallel positioning. A sensor installed in the flue stack provides the burner controller with continuous closed-loop feedback of the O2 concentration in the flue gas, allowing it to automatically make fine adjustments to the air/fuel actuators as needed for optimal combustion. This makes the burner adaptive to changes in air temperature, atmospheric pressure, or other factors that may affect combustion. Net annual fuel savings of 1-2% are typical when this technology is correctly applied.

Total Dissolved Solids Blowdown Control

Steam Boiler Rebate Value – $4,000

In addition to bottom blowdowns, a commercial or industrial steam boiler needs regular surface blowdowns to be performed in order to flush out excess treatment chemicals, debris, and other impurities that may naturally collect at the water surface during operation. In practice, we associate the concentration of impurities with electrical conductivity, which is relatively easy to measure with current technology. A total dissolved solids (TDS) automatic blowdown system monitors the water conductivity and automatically performs blowdowns only when required. This ensures minimal water is wasted while maintaining good water chemistry, which contributes to both energy efficiency and equipment longevity.  

Economizer

Economizers

Steam Boiler Rebate Value- $10,000 – 25,000

A stack economizer is a heat exchanger that extracts additional energy from a boiler’s flue gas and transfers it another medium which could be boiler feedwater, domestic water, or a hydronic heating loop. Economizers are typically found on larger boilers, usually mounted on top of the flue collector outlet. They offer the most energy savings in systems that consume a reasonably high percentage of cold make-up water, or where there is another consistent and substantial demand for water heating, such as a large domestic or process hot water load. Although economizers may add some complexity and space requirements to the system, they can produce significant energy savings when used in the right application. 

 

Boiler Controls- An Overview

Burner/Burner Control Retrofit (existing steam boiler upgrade)

 

Steam Boiler Rebate Value- Up to $49,000

Upgrading your existing steam boiler by upgrading the burner is a great way to increase fuel efficiency, improve reliability, improve overall boiler performance, and reduce maintenance/downtime expenses. Depending on the total project cost, FortisBC will offer up to $49,000 as an incentive for adding parallel positioning and oxygen trim to your existing boiler. In many cases, a burner retrofit can be completed within a few days, with minimal impact on the rest of your operations. Contact us to find out if your boiler is a good candidate for an upgrade!

Aldrich Steam Boilers

Aldrich Classic firetube boiler fitted with a Weishaupt burner

Here at Raven, we have been looking for a manufacturer that specializes in steam boilers for low pressure applications. Luckily, we found Aldrich, who does just that and more!

Established in 1936, Aldrich Company serves the global market as a premier manufacturer of firetube boilers and water heaters. Aldrich Company researches, engineers, manufactures and sells quality boilers and water heaters for a wide range of commercial and industrial applications.

The Classic Series 3-pass horizontal “scotch box” firetube boiler is available in sizes from 12 to 250 horsepower, with configurations as either low-pressure steam (15 PSI) or up to 80 PSI hot water boilers. The design is a hybrid between a 3-pass scotch marine firetube and a firebox boiler. It has the slim profile, easy maintenance, and economical cost of a firebox coupled with the durability, efficiency, and high-water volume of a horizontal firetube. Aldrich offers extra-thick flared tubes and tube sheets, making it a workhorse that is built to last for generations. This type of boiler is especially well suited in breweries, distilleries, and agricultural applications.

Linna and Bennett’s Trip to Maxi-Therm

Maxi-Therm joined the Raven product line only a few short months ago. They offer innovative solutions for steam applications, including steam to hot water, clean steam and many more. Linna and Bennett were the first of the Raven team to visit Maxi-Therm in Montreal!

Both Bennett and Linna were very impressed by Maxi-Therm’s innovative designs.  Bennett got the chance to take an up-close look at their approach to high pressure steam to hot water generation, which saves mechanical room footprint space and reduces energy consumption by 5-20% by eliminating all flash steam loss! They were also fascinated by the design of Maxi-Therm’s heaters. Not only are they compact, but they are also skid packaged that comes with required control valves and electronic controls for a simple plug and play install. Bennett and Linna got to see the various industries that have benefited from installing a Maxi-Therm package, including universities, hospitals, food processors, and many more.

The Maxi-Therm Facility has a state of the art research and development laboratory. This is where Bennett got a peak at Maxi-Therm’s most current energy-saving innovation – a micro steam powered motor that can both convert high pressure steam to low pressure steam and harvest lost superheat into electricity!

Aside from a great visit at Maxi-Therm, Bennett and Linna also enjoyed exploring Montreal. They visited Parc Maisonneuve, Mount Royal Park, and the Redpath Museum at McGill University. Even though the meals with the manufacturers were delicious, they couldn’t leave Montreal without trying a smoked meat sandwich and poutine.

Linna and Bennett also got the chance to head over to Security Chimney’s Facility in Laval. This was Linnas first time at Security, so she was happy to finally meet everyone and be able to put a face to everyone’s name. Linna expected most of the manufacturing to be automated but was surprised at the great deal of manual work and coordination required for each order. Now she has a much greater appreciation for all the custom pieces that Security manufactures for us!

Linna Heads to Fulton

Last month, Linna attended Fulton’s Sales Training in Pulaski, New York. This training covered Fulton’s hot water boilers, steam boilers, and thermal fluid boilers over the course of three days. Linna had very high expectations going into training, and Fulton did not disappoint!

Along with building boilers Rugged, Robust, and Reliable, it will not be long until the Fulton name becomes synonymous with innovation. Even after producing boilers that are known for their quality, they continue to find ways to make their boilers even more Rugged, Robust, and Reliable. During her training, Linna had the opportunity to see Fulton’s new Endura+ (Condensing Hydronic Boiler) and VSRT (Vertical Spiral Rib Tubeless Steam Boiler). Together, these products have no less than 50 patents pending worldwide!

Although seeing the construction of the boilers was a very interesting part of the training, Linna was most impressed with the team they have at Fulton. Every individual she met shared two common attributes: They were eager to learn, and always ready to share their knowledge. With a team that values continuous growth and has the ability to effectively pass on their wealth of knowledge, it is no wonder Fulton is able to attract and retain bright individuals capable of keeping Fulton the most innovative company in the boiler industry.
