G. Please provide a list of characteristics that are critical for pellet
fuels used in the units you manufacture (e.g., moisture content, ash
content, dimensions, etc.) and why you think so.

Ash Content, Moisture Content, Fines, Species of Wood, and Overall
dimensions are all important to the operation of our pellet units.
Variability of these characteristics has no doubt been the biggest
challenge to our end users (and therefore the manufacturers) over the
last several years. When the customer becomes accustomed to the
performance, heat output and maintenance intervals required by a
specific fuel…and then those qualities change, the customer is forced
to modify or alter how they use and maintain their appliance. This
isn’t necessarily the issue between “West Coast” and “East
Coast” fuel which we’ve dealt with for years, but variability of
quality and consistency within regions and sometimes within brands which
makes it difficult to keep up with. We’ve done all we can do to
educate our customers on visual cues which might suggest they need to
alter the operation of the units or increase the maintenance intervals
but more consistency and control of the composition and performance of
the fuel would:

greatly increase the satisfaction of our customers

greatly reduce warranty/customer service cost for manufacturers

result in finer tuned, cleaner burning more efficient appliances

Reduce the R&D costs of developing new units 

 

 LHV- the heat value of a combustion process assuming all the water
component is in vapor state at the end of combustion, so that its latent
heat is not available.

 HHV- the heat value of a combustion process assuming all the water
component is in liquid form of the combustion gas, the HHV takes into
account the latent heat of vaporization of water in the combustion
products.
