Wood Pellet Fuel

Wood pellet fuel is made from sawdust and ground up wood chips, which are biomass waste materials from trees used to make furniture, lumber, and other such products. Therefore very environmentally friendly as only waste products are used.

Typically wood pellet fuel have alow moisture content of approx. 5%–10% compared to 15% for
fuel shelled corn and around 20% for seasoned fire wood.

Some wood pellet fuels contain either petroleum or non-petroleum lignin used as a lubricant in the pellet production process, though most contain no additives. Pellets made from agricultural waste contain more ash, but can produce more heat than wood pellet fuel.

Under the PFI standards, there are two pellet fuel grades:

premium and standard.

The main difference between grades is in the inorganic ash content, premium pellet fuels [...] Continue Reading...

Pellet Stove Shut Down Operation

What are signs of performance problems?

Properly operated and well maintained pellet stoves experience few, if any problems. Most of pellet stove operation is automatic, but sometimes combustion air adjustment is needed.

Signs like a lazy, orange, sooty flame or dark smoke coming out of the vent (after startup and before shutdown) may indicate the need for more air or an overactive, "blow torch" flame calls for less air." Performance problems are more likely to be caused by neglected maintenance than by operation. Lazy flame, dark smoke, unusual sooting of glass, unexplained smoke spillage, and reduced heat output all point to the need for maintenance of appliance components and/or the venting system or for remedies for house depressurization. Problems related to mechanical failure usually result in safety switches shutting the [...] Continue Reading...

Other factors for Venting System for Pellet stoves

Besides appliance requirements, what other factors may be considered in specifying pellet venting systems?
The following factors may play a role in the designation of the venting system:

Altitude: Sounds funny but the higher the altitude installations, generally higher than 2500 feet above sea level, may require special venting options to provide adequate combustion air and/or draft.
House Pressure: Extremely tight house construction or strong kitchen, bath, or other exhaust fans may create a negative pressure within the home that decreases venting effectiveness. May necessitate an approved outside air source.
Windy Conditions. Unpredictable effects of high winds or prevailing wind conditions may necessitate the addition of vertical venting extending above the roof [...] Continue Reading...

Pellet stove venting layout

Options for venting layout?
Mechanical Exhaust:

Sidewall horizontal venting (Figure 9). Is the least expensive venting system. Disadvantage of potential smoke spilling into the house in the event of a power outage or component failure, or house depressurization , also can leave an ugly black smoke mark on the wall.
Horizontal vent with backup vertical venting (see Figure 10). Preferred horizontal method that avoids venting problems associated with unexpected appliance shutdown. Smoke mark will still occur.
Vertical venting through the ceiling and roof (Figure 11). Has the advantages of keeping vent gases warm and of providing natural draft to prevent problems in an unexpected shutdown.
Venting into existing chimney. Stove [...] Continue Reading...

Pellet stove Ventilation

What are the purposes of venting systems?

Proper ventialation is an essential for proper appliance performance, dwelling safety, maintenance frequency, and general indoor environment. Pellet stoves appliances will produce little or no visible smoke after startup, but water vapour,exhaust gases and fine ash must be removed safely from the appliance to the outdoors.

The purpose of all vents is to remove combustion by-products during normal pellet stove operation. For most pellet stove designs the exhaust is mechanical by means of blowing the combustion by-products out and pulling air needed for combustion into the fire, nowdays few pellet stoves operate without a combustion air fan and use natural draft both for exhaust and combustion air intake. Protection of nearby combustibles is essential. The minimum clearance between the vent and combustibles, as [...] Continue Reading...

Pellet Stove Starting Operation

Where do we start?

The obvious would be the instructions that accompany the pellet stove appliance, generally operating a pellet stove is not difficult, but it maybe new technology so it calls for some basic knowledge.

Training vides accompany some stoves, and hands on demonstrations are done by many dealers and installers.

How do I start a fire?
Most designs make start up easy by using Small dry pellet fuel and combustion air. Operating instructions provided with the stove give the specific steps to follow.

Manual ignition stoves call for the owner to apply an approved gel or solid starter material (no liquids), light the pellets, and monitor the fire to see that the fire catches and the flame gradually grows. On the automatic ignition pellet stoves, pushing the start button feeds pellets [...] Continue Reading...
