Wood Pellet Boiler

There are various different form of solid biomass fuel heating, including basic logs stoves, wood chip systems and pellet stoves. However for larger properties a wood pellet stove generally isn't sufficient to meet the heating demands of the property. Therefore a wood pellet boiler is a more suitable alternative. The wood pellet boiler shares many of the same internal component features of wood pellet stoves, the main differences are how a wood pellet boiler captures heat from wood pellet combustion. Wood pellet stoves generally provide heat via hot air and heat radiation from the stove its self. However, this only generally provides sufficient heat the room in which the stove is located. Some pellet stoves do have back boilers fitted. Here the heat generated from the wood pellet stove is split, usually 20% via hot air and 80% through the back boiler. The back boiler can then be connected up to your existing central heating system to provide heat via radiators or under floor heating. For large properties, a dedicated wood pellet boiler is used. The positioning of the wood pellet boiler is generally in the basement, in the garage or out-building. This means the wood pellet boiler can be located closed to the fuel source and also makes daily maintenance easier.

Wood Pellet Heating and Pellet Stoves

When purchasing a wood pellet stove or wood pellet boiler, it is important to remember that not all pellet burners are equal. Some wood pellet boilers are heavily focused on only premium grade fuels, and high automation with several maintenance saving features. These features include springs which clean the heat exchanger tubes at regular intervals. Also, some systems come complete with ash compression systems. Here, the ash will be compressed into a brick. This means the owner has the remove the ash less often and in its compressed form, is cleaner to remove. Though these features are very useful, they do however severely limit the abilities of the pellet burner.

Wood Fuel Pellet and Ash Contents

Different sources of wood, produces wood pellet fuel of various ash contents. Premium grade fuel produces a very low ash content of only 0.5%, where lower grades of wood pellets produce ash content around 2-3%. Though many consumers choose only premium grade fuel, the cost of these pellets is only set to increase. There simply isn't enough resources to meet future market demand with premium grade pellets. Therefore as demand increases and supply reduces, the price will inevitably increase. This will prove a particular issue for consumers who purchased wood pellet boilers which can only burn low ash premium fuel.

Wood Pellet Making Machine and Facts

More people are interested in getting involved in producing their own pellets, either to start their own pellet company or just to produce enough pellets for their own needs and maybe that of friends and family. Well it all starts with choosing a suitable raw material. This raw material will then needs to be processed through a chipper/shredder and finally by a hammer mill to produce a consistent particle size for the pellet machine. The particles are then compressed.
