I came across a strange video the other day, of a pot of wood pellets burning away, and then a collection of fuel sells are placed on the fire. The heat energy is then converted into electrical energy to charge the phone. Interesting stuff, and in the future such technologies may be able to be integrated into the pellet stoves and boilers so they can run without main supply.

I’ve recently come across a really nice video of a wood pellet plant in the US. The video contains quite a bit of detail on their operation. They are currently producing premium pellets, and aiming for the 0.5-1% ash bracket. However they do wish to move into producing a more standard pellet in the future. The standard pellet will produce higher ash content, however it will be cheaper to produce. Currently there is a lot of wood residue, which cannot be processed into fuel pellets because it is not suitable to produce a premium grade of pellet. However many pellet stoves and boilers can only burn a premium standard of pellet fuel. This is where is it an advantage to purchase a more fuel flexible pellet stove or boiler to be able to use a cheaper standard pellet, instead of only premium pellets.

The video shows their process from start to finish. They have chips delivered by truck, and they go through the first hammer mill. These chips then get dried to probably around 10% moisture content, and then they go through a second hammer mill to reduce the particles ready for the pellet mill. They are using a series of ring die pellet mills to produce the pellets, which are then cooled and sent to a large storage silo.

Small-scale pellet production is a rapidly growing pellet fuel sector. Below is a video of a portable bagging solution than can be used along with wood pellets to quickly package the wood pellets for the domestic pellet fuel market.

Torrefaction is a process not very well known, however this is the future of the biomass sold fuels market. Torrefaction is a thermal process to increase the energy density of the raw material, and give it several other benefits.
The video below is from New York State University carrying out Torrefaction tests on wood. Basically the wood is heated to around 300 degrees. At this temperature the wood looses almost all moisture and other volatiles. The benefits of Torrefaction include:
1. A very low moisture content
2. A smokeless fuel which also has no smell
3. A water resistant fuel
Through then creating pellets from Torrefaction materials means the energy density of the fuel can be increased further. For example one torrefied pellet provides the same heat as two normal wood pellets. For example if you usually use 3 tonnes of pellets a year that is reduced to 1.5 tonnes of torrefied pellets. There will be more on torrefied fuel pellets in the future.

Many European countries are now heavily participating in wood pellet production and Switzerland is no different. The video below provides a brief introduction to large-scale wood pellet production in Switzerland.
As you can see from the video, using only natural and uncontaminated wood residue is suitable for wood pellet fuel production. Producing wood pellets from contaminated wood waste with paints and resins can produce harmful emissions during combustion, which is bad for people and the environment.
Modified cornstarch is referenced as been added to the mix before the pellets are produced. Modified cornstarch is a recognized pellet binder, and lubricant for the pellet production process to increase productivity and lower energy demands.

Due to currently low prices of natural gas and oil, the growth of wood pellet stoves would not be expected to be as large as last year. However as part of the economic stimulus package a 30% tax credit up to the value of $1500 is available to help to pay for the stove and installation. The scheme is set to run to the end of 2010.
As many people will realise the current low oil and gas prices are only temporary. As we are in an economic recession the prices of oil and gas drop also. However prices of oil and gas are already on the rise and will continue to rise in a general trend.
Purchasing a pellet stove now and taking advantage of the tax credit scheme will make the payback time of the stove even less.

Wood pellets maybe seen only as a type of home heating fuel for pellet stoves and boilers. However developments are now taking place to see wood pellet fuel provide more of the energy we use. Cyclone Technologies have developed the WHE engine. The WHE engine is a self-contained steam engine, however this design is completely different to any steam engines that have existed before and is highly efficient.
In the video below you can see a demonstration of the engine being powered by a wood pellet fuel fire. Each engine can generate around 10KW of electricity, meaning just one of these engines can cope with the average power demands of the average sized home.
The WHE engine running from a pellet burner does open up many exciting opportunities for the use of wood pellets. As small-scale power generators could set-up powering the local town and community, generating local jobs. Homeowners could also set-up a generator, with any excess energy going back to the grid in return for credits.

In Illinois farmers are experimenting with growing various different types of energy grasses to be produced locally into pellets to be used as home heating fuels. Switchgrass and Miscanthus are their current main focus for energy crops. They currently feel Miscanthus has the edge on productivity, however Switchgrass has other advantages including providing a habitat for local wildlife.
The farmers and University understand the benefits of local energy loops, as we do at PelHeat. Locally producing crops and pellets for local use has multiple advantages. It supports the local economy on several levels. And reducing transportation of raw material and pellets is better for the environment and means a cheaper fuel for the end user.
In the video the furnace that burns the pellets is shown, however very little detail is provided on the furnace its self. From our own experience here at PelHeat, we know what its like to burn energy crops, and which pellet stoves and boilers can burn the pellets efficiently. Therefore we have created a guide detailing what to look out for when buying a pellet stove or boiler to make sure it has the most features for the money, and which can burn other biomass pellets such as grass pellets.

Ben from Victory Gasworks has finished development of their first small-scale gasifier to go on sale. The product is called the Woody ESP, which stands for emergency and secondary power. In the video below Ben gives a summary of the features on the Woody ESP, and shows the unit in operation.
To begin with Ben shows the lid to the hopper where the fuel is loaded. The hopper and combustion zone on the Woody ESP is highly insulated. The reasons for this is so the unit can reduce tar formation as much as possible to generate cleaner gas, which means the filters will not have to be cleaned as often and produces a more reliable operation.
Secondly Ben shows the various ports on the unit for it to breath, ignition port, ash clean out and ejector port. Ben has replaced the cyclone for initial gas cleaning and gone for a coarse filter, as stated this will still have some cyclone benefits. Ben then shows the condensate drain, this is where the moisture in terms of steam is released from the process. The final filter goes through a cooling system and then finally through an after market filter. The process should produce very clean gas for use in a combustion engine.
Within two minutes the gasifier is producing gas, Ben then shows the high operating temperatures of the woody gasifier before sending the gas to the small generator. The small tank is a final condensate tank to remove as much moisture from the gas as possible before it enters the engine. Ben also shows how clear the water condensate from the process is, this illustrates the high filtration of the gasifier.
Using Biomass Pellets in the Woody
Currently Ben mainly uses wood blocks in the Woody, however he has had successful trials with wood pellets. However there are some issues with this design of gasifier when using biomass pellets, which I will talk about in the next post.
