Below is a video from Auburn University on their biomass gasifier. The biomass gasifier can use many different types of biomass to produce heat and gas. The biomass is burned in a combustion chamber where air is injected at several different layers. The biomass passes through several stages of combustion eventually to create wood gas or singas as it maybe called. This gas can be used to run internal combustion engines and heating systems. The Auburn application uses the gas to run an internal combustion engine, which then powers a generator.

Biomass pellets are commonly used to run gasifiers due to their uniform size and moisture content. The size of the gasifier can be kept to a minimum, as raw material processing is not required. As biomass pellets do not require drying all the heat generated from cooling the gas can go to heating buildings. Therefore a biomass pellet gasifier becomes a combined heat and power unit (CHP). The PelHeat Mobile Pelletizer could be used to create pellets to be used in small-scale biomass gasifiers. The gasifier could then be used to generate heat and electricity.

At PelHeat we often talk about the advantages of our small-scale mobile pelletizer, in using local resources to produce energy for the local community. A small island near to Denmark has taken this philosophy on board, and put it to good use. Through this approach they have given themselves fuel independence will stable prices.

The islanders believe as we do that decentralised energy production has both environmental and economic advantages. We believe the PelHeat mobile pelletizer can contribute to local energy production solutions.

We have completed the first prototype of the mobile pelletizer; with this we will continue our development and testing to design the finished unit for sale.

We collected the unit from our engineering partners in Sheffield; we then towed the unit over the Peak District National Park. This was as good a test as any for the road handling of the unit, as the roads over the park are a favourite of many motorcyclists. The unit handled the winding roads with ease, and our Nissan X-Trail, which is not the most powerful of cars, had no problems towing the unit over the hills of the Peak District.

We are very happy with how the mobile pelletizer is shaping up, and we are also happy that the Perkins diesel engines are the right choice for the finished products. We have based the unit on an Indespension trailer, which is very rugged with a strong support frame and the ‘SuperRide’ suspension handles the weight of the equipment very well. As well as the PelHeat Mobile Pelletizer been made in Sheffield, both the Perkins diesel engine and the Indespension trailer are also made in the UK.

Now we have our first prototype we can continue to test the unit and design the final product. There will be more pictures and some videos of the unit appearing soon. If you would like to register your interest in the product please contact us at:

In the PelHeat Mobile Pelletizer we are using flat die pellet mills. These pellet mills consist of a die, which is horizontal mounted with rollers resting on the die applying vertical pressure down onto the die surface. Below is a diagram to demonstrate the process.

A = Raw Material
B = Die
C = Material Carpet
D = Pellet Compression
E = Pellet

There are two main types of pellet mill used to produce pellets, and they are ring die and flat die, the reasons we are adopting a flat die pellet mill are as follows.

Size and Weight
Flat die pellet mills are a lot more compact than ring die pellet mills. Building a mobile pelletizer on a trailer platform space to place the equipment is very limited. Therefore a flat die pellet mill is better suited for the application on this scale.

Maintenance
In designing the mobile pelletizer we are focused on making the unit as easy to maintain and clean as possible. This includes the pellet mill, for example on how easy it is to disassemble the pellet mill to change or clean the die. Ring die pellet mills are notoriously awkward to access to clean and change the die. However with the flat die pellet mill the die can be removed within a couple of minutes.

Visibility
As stated in the PelHeat Making Pellets Guide and throughout the website and blog I indicate that producing pellets from multiple biomass raw materials is a skilled process. As such not every material when placed in the pellet mill will create good pellets first time. With ring die pellet mills the pelletizing chamber is sealed and covered. With the flat die pellet mill it is possible to view directly into the pelletizing chamber. By viewing how the material performs in the chamber and what quality of pellets are produce the user can use that information to alter the material. A view of the pelletizing chamber also gives an indication if the die has become blocked, so it can be cleaned or changed as quickly as possible.

Summary
Ring die pellet mills have their place in the industry, particularly large scale pelletizing, however flat die pellet mills are more suitable for small scale applications.

A PelHeat we wish to encourage users of our mobile pelletizer to upgrade their local biomass and biomass waste resources into pellets, to meet their own heating needs and the needs of local like-minded individuals. To do this we are constantly on the look out for suitable biomass pellet burning applications that can utilize the various biomass pellets effectively.

Bixby Energy also believes in this philosophy and has developed systems to burn such pellets, as in the Bixby MaxFire and UBB, and they are continuing to develop biomass pellet burning appliances. The following video states the importance of biomass pellets, and the positive benefits they can bring to the national and local economy.

If you have biomass or waste biomass, which you wish to pelletize for your own heating needs and the needs of the local community, please visit www.pelheat.com for more information on the PelHeat Mobile Pelletizer.

As you know, at PelHeat we wish to encourage a wide variety of biomass resources for pellet production with the PelHeat Mobile Pelletizer. The main issue with this is to source units that will effectively and efficiently burn a wide variety of fuels. Pellets made from biomass such as Switch grass, Reed Canary Grass, Miscanthus and various straws have always interested us. GrassBioenery.org have completed a test of various pellets stoves on their abilities to burn grass pellets. Compared to wood pellets, grass pellets generally produce more ash, more corrosion and are more likely to produce clinker/sinter and slag around the heat exchanger tubes. So only certain types of stoves have the ability to burn grass pellets effectively.

Traditional Wood Pellet Stoves

In a traditional wood pellet stove design, the pellets are top feed and fall into a burn pot. A fan blows the ash from the burn pot into the ash draw and more pellets are feed into the burn pot.

This design does not cope with grass pellets because of the following reasons:

1. The blower is designed to blow away wood pellet ash with is generally around 0.5-3%. With grass pellets producing on average above 3% the blower does not remove enough ash, and this eventually extinguishes the fire.

2.Grass pellets can produce a clinker/sinter, which is a dense mass of melted ash. Therefore the blower cannot remove this clinker/sinter from the burn pot into the ash draw, which again will eventually extinguish the fire.

Multi-fuel Pellet Stoves

For a stove to burn grass pellets it must be able to address the issue of the increased ash content and clinker/sinter. The flowing stove designs work more effectively with grass pellets than traditional wood pellet stoves.

Bottom Feed

With the bottom feed design, pellets are auger feed from the bottom of the burn pot to the top. The burning of the pellets takes place on the lip of the burn pot, as new pellets are feed in from below, the ash or clinker, which is on the lip of the burn pot, is pushed over into the ash draw. The design is very simple, but effective.

Mixing Auger

This design is similar to the bottom feed design, but in this case there is an additional mechanical auger. This mechanical mixing auger can agitate the material in the burn pot; so can brake up any ash or clinker issues. Again a simple principle, but effective, also GrassBioenergy.org believe that this design of stove may work with pellets with an ash content exceeding 5.2%.

Summary

When producing pellets with the PelHeat unit, your raw material will generally produce pellets with a higher ash content than premium wood pellets and may cause a clinker with grass pellets. Purchasing a pellet stove with a bottom feed or mixing auger design will give you a better chance of been able to burn a wide variety of biomass pellets.
