Frequently Asked Questions

Who is manufacturing pellet stoves specifically to burn grass?

GrassBioenergy.org: Frequently Asked Questions
No company is doing this, but several are attempting to modify their stoves to better manage high ash fuels.

How much routine maintenance is required to burn grass in pellet stoves?

GrassBioenergy.org: Frequently Asked Questions
Routine (weekly) maintenance is recommended for burning any type of pelleted material (including wood pellets) in any pellet stove. Aside from dumping ash at necessary intervals, the heat exchanger and burn pot area will need cleaning at least once a week. The flue pipes should be inspected for buildup at regular intervals.

Can I burn grass pellets in my pellet stove?

GrassBioenergy.org: Frequently Asked Questions
Most likely not. Average pellet stoves with a standard burn pot are not designed to cope with high ash content. In general, corn stoves will have more potential to handle grass pellets because they are designed to deal with a somewhat messy residue. This is no guarantee that corn stoves will burn grass, corn stoves sometimes have difficulty dealing with corn.

Can pellet boilers burn grass pellets?

GrassBioenergy.org: Frequently Asked Questions
Not yet. The major advantage of boilers over stoves is that they provide hot water and central hot water heating. Commercially available pellet boilers are designed to burn wood pellets and possibly corn pellets. They have no means of dealing with high ash content. They can successfully burn grass pellets, but will generate a large clinker that would need to be removed from the burn chamber every 6 hours or so, in order for the boiler to continue functioning.

What are the disadvantages of grass pellet fuel?

GrassBioenergy.org: Frequently Asked Questions
As with coal or wood stoves, and wood pellet stoves, routine maintenance is required. Pellet handling and ash removal make this less convenient than fossil fuels. There are some emissions as is the case with burning anything, but nothing like the wood stoves of the past.

What materials and products can be used to vent pellet stoves?

Frequently Asked Questions
The product specifically tested and listed for use with pellet stoves is PL vent pipe, labeled as tested to UL 641. PL vent pipe is double wall pipe; the stainless steel inner pipe that carries the exhaust products is separated from the outer wall by an air space. Pipe joints must be sealed gas tight to prevent exhaust products moving through the vent under pressure from leaking into the home. Stoves tested and listed with PL vent requirements cannot safely be vented with substitute materials.

Who is burning grass pellets in stoves at this time?

What species are acceptable for grass pellet biofuel?

GrassBioenergy.org: Frequently Asked Questions
All grass species and mixtures. Legumes may not work quite as well but also may be acceptable. Grass crop selection should match the soil type, for maximum sustainability and productivity.

Where in the US does grass pellet biofuel have the most potential?

GrassBioenergy.org: Frequently Asked Questions
The Northeast. For many decades the Northeastern US has been officially labeled as the “Hay & Pasture” Region of the country. Like much of Europe, the temperate humid climate is not so hot for corn, but perfect for grass.

What would it take to get a grass pellet biofuel industry up and running?

Will the nutrient burn the grass if I have a blow-out or a head sticks on?

FertiGator - Automatic Fertilization for Irrigation Systems
Unlike other systems, the FertiGator only works when the irrigation system timer is intentionally opening zones. In addition, "the micro-dosing injection rate of the system is designed to prevent this from ever happening. This means the fertilizer in that water will be very diluted. You will have a greener area, but you will not burn or damage the turf."

How do I implant the pellet?

Innovative Research of America - Frequently Asked Questions
For pellets up to 5mg we recommend using one of our precision trochars. Detailed instructions for implantation using the trochar or for pellets larger than 5mg can be found on our website, click here. Also, if you are implanting both placebo pellets and pellets containing the active product concurrently and you are using a trochar, implant the placebos first to avoid any residual active product contaminating the placebo pellets.
