Portage & Main Outdoor Wood Boilers

Welcome to Strawbale Farms, Inc
Portage & Main Outdoor Boilers

Strawbale Farms is a renewable energy company that focuses on biomass heating and energy efficiency. With many years of experience in the renewable energy industry, we know efficiency " RESULTS " when we see it. It is our pleasure to offer our customers the most efficient and innovative line of Conventional Outdoor Boilers, Wood Gasification Boilers and Automated Woodchip Boilers made today. Known as the "Original Efficient One" since 1973, PORTAGE & MAIN BOILERS are the best built, longest lasting and most efficient boilers in the industry. PORTAGE & MAIN BOILERS Burn one third to one half less wood than any other brand of outdoor boiler.



Great News!

Under new EPA regulations conventional outdoor boilers are still legal for farm and commercial use. Shaker grate models that are rated to burn coal or wood/coal (Canada) are legal for residential use until 2020!


Portage and Main has taken the best design in the outdoor boiler industry and made it better with our revolutionary Ultimizer series. Proper combustion in a boiler requires heat, fuel, and oxygen. To provide the most heat, PORTAGE & MAIN BOILERS incorporate the use of refractory cement in the fire box. 2.5 inches of stainless steel reinforced precast refractory cement line the bottom of the fire chamber on all four sides. This is the most important major innovation in outdoor boiler design to date.



The reinforced refractory cement surrounding the fire provides;

  • Much Hotter Burn Temperatures for Proper combustion.
  • Hotter Temperatures Allow for the Most Complete Combustion Within Any Conventional Outdoor Boiler.
  • More Complete Combustion Means a Cleaner, More Efficient Burn.
  • Hotter Combustion Temperatures Eliminate Creosote, Moisture, and Their Damaging Effects.
  • Hotter Combustion Temperatures Equal A Cleaner, Dryer, Longer-Lasting Outdoor Boiler.


Built like an industrial boiler the PORTAGE & MAIN Ultimizer series is by far the best value of any conventional or gasification boiler on the market today, giving our customers a much higher return on investment.
Features include :

  • Only Boiler With Double Welded Joints (Boiler Style Welding).
  • Dry Refractory Lined Bottom For A Hotter Cleaner Burn.
  • Preheated Under Fire and Over Fire Air For Better Combustion.
  • Unique Independent 180 Degree Reverse Turn Heat Exchanger With Horizontal Flues For High Efficiency.
  • Unique Modular Design.
  • Twice the Lifespan of an Average Boiler.
  • Burns 1/3 to 1/2 Less Wood Then Other Conventional Boilers.
  • Efficiency and Longevity Without The High Cost of A Gasification Boiler.

Dare to Compare PORTAGE & MAIN BOILERS To Other Brands And You Will See There Is Only One Choice for Your Heating Needs, PORTAGE and MAIN!

PORTAGE & MAIN OPTIMIZER EGR 100 and EGR 250

Wood Gasification at Its Best!

Again, PORTAGE & MAIN sets the standard for efficiency and longevity with our industry leading Optimizer EGR series. The key to efficiency and longevity in any boiler is refractory and heat exchange, the Optimizer EGR delivers both. The Optimizer EGR is built with more refractory than any of our competitors. Refractory is a special type of cement that is used in high temperature applications such as large commercial coal and biomass boilers, steel mills, brass and bronze foundries, and many other high temperature applications.
Refractory:

  • Creates Much Hotter Burn Temperatures.
  • Does Not Corrode.
  • Last Longer Than Steel in High Temperature Applications.
  • Retains More Heat Than the Same Volume of Water- OVER TEN TIMES MORE!
  • Keeps the Boiler Hotter Longer for Easier Refire and in Power Outages.
  • Keeps the boiler dry and corrosion Free.
  • More Refractory = Better Longer Lasting Boiler.
Most gasification boilers use little to no refractory. All large commercial boilers are refractory lined and have been for over 200 years, For a Reason!


HEAT EXCHANGE

EPA New Source Performance Standards regulate emissions, not efficiency. Most manufacturers responded by building the least expensive boilers they could to meet the new emission standard, without regard to efficiency. These types of boilers have vertical heat exchange tubes only, and are much easier to build.


The PORTAGE & MAIN Optimizer EGR is built to a much higher standard. Like all large commercial boilers the EGR has horizontal and vertical flues for maximum efficiency and longevity. The EGR is the only boiler to have a series of water jacketed horizontal flues in the base of the boiler next to the reaction chamber for maximum contact between the superheated exhaust gases and the heat exchange tubes. When the flue gases leave the reaction chamber they must immediately turned 180 degrees and pass through a series of horizontal flues then turn other 90 degrees to pass through the vertical flues. This design is much more efficient, gives you quicker recovery times and lower stack temperatures which equals less wood and a better return on investment over time.


SO WHY BUY HALF A BOILER WHEN YOU CAN BUY A WHOLE ONE?

PORTAGE & MAIN does not skimp! Because of our double welded joints (exclusive to portage and Main), generous use of refractory in the firebox and water jacketed horizontal flues in the base, PORTAGE & MAIN BOILERS generally weigh 20% to 35% more than our competitors, which makes a better boiler.


PORTAGE & MAIN BOILERS, Setting New Standards for Efficiency, Quality And Longevity!
