Wood Stove And Wood Pellets Along With Incineration Pellets
January 28, 2010 by Go Green Tips
The common interpretation of a wood stove, is a log stove. Incineration logs as a source of heat in a living room or open plan living space has been done for hundreds even thousands of years. Though, for many years the humble log stove has been seen more as one more heat source for one room or even a style option, rather than a complete solution to house heating. There are quite a few reasons for this, firstly a log stove is a lot of work for people by a busy modern lifestyle. The stove will also not generate a lot of useable heat, it may create the living room very warm, but the rest of the property will not benefit from the heat. A modern biomass stove which can meet the users demands must generate more useable temperature plus at the same time be low maintenance. Yet biomass logs are the predominant interpretation of biomass, there are many other forms of biomass which can also be used as wood energy. Wood simply refers to any form of organic material which can be used as a energy source. This includes wood logs, but also biomass chips along with sawdust from biomass processing operations. There are other sources of wood such as agricultural waste such as grass in addition to other waste from food production. This wood supply is particularly under utilized along with has very little value. Most wood resources though cannot be used as energy in their raw form. Efficient burning is down to energy density and fuel moisture content. To process wood into the most efficient form of solid fuel, the most practical process is to upgrade the wood into pellets. Pellets have a much higher density, along with also have a low moisture content, producing more heat.

The properties of pellets mean they flow well through feed hoppers along with can light quite easily plus quickly. This method that pellets can easily be used in automatic as well as sophisticated heating systems. Biomass burners therefore can be restricted via a thermostat the same as any other oil or gas heating system. When the thermostat demands more heat the auger system on the wood stove will feed more pellets into the fire. If the fire is not lit, then a hot rod igniter will start the fire with a higher fan speed. Once the fire is lit the fan speed will lower to achieve the correct combustion temperature to maximise heat generated while keeping fuel consumption to a minimum. It is these features which makes biomass pellet stoves more of a realistic full heating solution.

The biomass stove can be used to provide temperature for a single room, or by way of a boiler can be used to feed into your existing central heating system. The amount of maintenance required for the pellet stove will depend the features included in addition to the size of the fuel hopper. Generally the size of pellet energy hopper on the biomass stove will hold ample fuel for at least a day, which is already much greater than a log stove, which will need fuel loading quite a lot of times a day. However some wood pellet stoves can have energy hopper extensions so the stove can run for a week or even quite a lot of weeks without the require to refuel. To minimise energy loading, it is likely to link a wood stove by way of an large external fuel hopper which will feed the smaller hopper on the stove. The large external hopper can hold up to year worth of fuel, in addition to be loaded by way of a pellet fuel tanker which blows in pellets.
