Heating the Northeast

Tuesday, May 4th, 2010

Thanks to Charlie Niebling of New England Wood Pellets and his intrepid band of organizers at BTEC, Maine Pellet Fuels Association, Pellet Fuels Institute, New York Biomass Energy Alliance, and Alliance for Green Heat, among others, the second annual Heating the Northeast Conference held last week in Manchester, NH, was an energizing event to a sold-out house.

Business representatives from all corners of the “biomass thermal” world were present to show their wares, share information, and plan for the future of the fuel and paradigm switching that must come as petroleum products become increasingly scarce and quests for them carry ever higher environmental risks.

During the event NH Senator Jeanne Shaheen made a virtual appearance throwing her support behind the important transition and behind bills that are working their ways through the Senate to incentivize the installation of renewable resource technologies for space and water heating.  In addition, the State of New Hampshire made an announcement that it would provide incentives to home owners of 30% of the cost of newly installed qualifying biomass central heating systems up to $6,000.  Oh, that all State governments were as forward-looking.

I left this year’s event with a couple of very strong feelings.  First, in two ways, this conference felt a bit like preaching to the choir.  There were few in the room who weren’t fully subscribed to the importance of a switch away from fossil fuels and toward renewable biomass alternatives.  Several who weren’t fully subscribed stood up to worry out loud about over-harvesting of regional forests demonstrating both their philosophical perspectives and their need for understanding of actual harvest patterns and fiber availability in the northeastern U.S.

Unfortunately, several of those who had various podiums used their time for infomercials we all could have been spared.  This was a small problem to be sure but one which should be addressed as next year’s speaking forces are recruited.

Second, the vendor display area represented a remarkable opportunity for the general public to begin to understand this technology which is commonplace in Europe but new to us. The organizers would do well next year to schedule one day for the general public to see the vast array of products, to talk with knowledgeable vendors about them, and to hear a session or two on the benefits of biomass used as a thermal energy.

The culminating experience for the Conference was the distribution of “A Bold Vision for 2025,” the work of the five organizing groups listed above.  The glossy summary and the more developed white paper are both available on the Maine Pellet Fuels Association website.

Growing interest

Friday, January 15th, 2010

On January 20 and 21, Maine Energy Systems will be conducting its monthly training session for installation and maintenance of its AutoPellet line of pellet-fired boilers. As is customary, Herbert Ortner, the founder and owner of OkoFEN Pelletsheizung of Niederkappel, Austria, will conduct the training as he does in ten Western European countries.

However, the participant list in this session of training is indicative of a growing awareness in our region of biomass as a heating alternative for homes, businesses, and institutions. Typically held to 15 participants, this session has swelled to more than 20 participants because of growing interest from those outside the normal ranks of installing contractors.

The coming session of training includes participants who are members of five separate heating engineering firms, two of them do project engineering only, two of them are installing engineering firms, and the fifth is a very large scale engineering, installation and service firm.

In addition, four trainees represent a large oil distributor from western Massachusetts, one is from an established alternative energy company, and two are from the New York State Energy Research and Development Authority.

Notably the Director of Technical Education for Maine Energy Markets Association, formerly Maine Oil Dealers’ Association, will also be among this month’s trainees. The group is rounded out by the traditional installing contractors who will make the products available to their customers.

The remarkable and sudden growth in interest in learning about biomass heating for buildings of all sizes in our region is a strong indicator that people are concerned about growing our local economy through consumption of “homegrown” fuel, about substantially reducing the portion of our carbon footprint attributable to space heating and about preserving oil stocks for more critical applications.

OkoFEN Training

MESys has become the first importer of the renown OkoFEN pellet boiler systems from Niederkappel, Austria. The boilers are marketed by MESys as their AutoPellet line and come in capacities ranging from 41,000 BTU/hour to 191,000 BTU/hour for stand-alone boilers and for capacities up to, and beyond, 764,000 BTU/hour for staged units.

Herbert Ortner, owner of OkoFEN and Maine Eco Pellet Heating LLC, was the first to produce a pellet boiler in Europe in 1997. Since that time, he has refined and improved his line of pellet boilers to be the most sophisticated in Europe with the deepest penetration in the European market.

During the last week in August, Herbert came to MESys headquarters in Bethel, Maine, to train regional contractors on the installation and maintenance of the OkoFEN boilers. The two day training sessions were filled to capacity. During the sessions contractors learned about the use of biomass as a residential heating fuel, began to understand global efforts to replace fossil fuels with renewable fuels, and had plenty of time with the boilers. The three demonstration boilers were disassembled and reassembled by all present and ample time was spent configuring and adjusting boilers using control box simulators created by OkoFEN for the task.

Training sessions will be held regularly to ensure there is an adequate workforce to install and service these systems.

I enjoyed the session and was stricken by the greatly increased user-friendliness of this system over those I’ve been familiar with, including my own MESys 4000. The burning technology in these systems is a bottom-fed design, which has pellets burning on a “blade,” or plate that feeds secondary air to support the combustion. Ash and other combustion by-products simply fall off the blade into the bottom of the boiler as new fuel emerges from the center of the blade to be burned. This feed system reduces burner sensitivity to unwanted combustion by-products like clinkers and slag.

Once in the bottom of the boiler, the ash is compressed into a removable container for easy user cleaning on infrequent bases determined by fuel consumption rates.

That these systems approach liquid fuel burning systems in their ease of use should help the US market find adoption easy for the economic and environmental benefits realized by conversion to regionally produced, renewable fuels.
