Wood is a collective reference to any natural material which can potentially be used as a energy source. This covers a very wide range of materials. The main examples of biomass that many people refer to are woody wood. Woody biomass has been used traditional for thousands of years by means of logs on open fires. However, this form of wood incineration is not very efficient, as very little of the energy generated from combustion is actually captured for the core use. The modern form of biomass incineration focuses on two main key principles. Firstly to decrease the amount of wood required for energy construction. This is achieve by means of rising combustion efficiency of the wood used. This refers to upgrading the wood, this can be processing the wood into a liquid or gas, or in the form of highly compressed energy pellets.

Biomass energy pellets are essentially the same raw material in a compressed form, by a much lower moisture content. Moisture is a key obstacle to efficient combustion. To get more of a complete burn where the carbon is used efficiently producing less smoke along with particulates, high combustion temperatures have to be achieved. Moisture in the fuel stops the incineration zone reaching these high temperatures. Pellet energy for case has a moisture content below 10%, and in some cases this is closer to 5%. If you compare these figures to the 50% of virgin wood timber, it is clear to see why wood combustion of energy pellets is much more efficient than simply incineration logs. The extra important factor is energy density. The compression of a energy pellet is several times that of the raw matter. This means again a much more complete burn can be achieved by way of higher combustion temperatures. Fuel pellets are a fairly easy means to upgrade biomass into a modern fuel.

Woody wood has always been the focus of wood burning, though to purely focus on woody wood would neglect a huge volume of biomass that has to be dealt by way of. A key instance of this is agricultural wastes, such as straws in addition to grasses left over from food production. These resources have conventionally been burnt in the field, producing large volumes of smoke in addition to producing no benefits at all. These resources can be collected and also processed into fuel pellets. This would help address an additional key issue of the 21st century in the cost of food. Upgrading the straw into fuel pellets would generate a secondary revenue for the crop, as well as dropping the fee of food. Upgrading biomass into a more proficient form of solid fuel is only one component of the solution. Developing more efficient ways to burn the fuel pellets is also crucial. Modern pellet stoves as well as boilers are now established as modern heating appliances. By way of direct air injection to the fire at a controlled rate, higher combustion temperatures can be achieved while dropping fuel consumption. These biomass incineration ideas can also feed the combustion zone by means of pellets at a controlled rate to maintain the desired temperature. Additional features included automatic ash cleaning.
