One more key aspect of the quality of premium grade pellets are their mechanical durability. This simply refers to the density of the pellets, plus how well they hold their shape. A premium pellet formed under enough pressure in addition to heat should have a smooth surface plus shine. The pellets should not easily crumble, and should not make excessive fines. Mechanical durability is an important feature for efficient incineration. Pellets by way of a low mechanical durability will separate during combustion causing increased smoke, lower heat values in addition to higher ash content, as complete combustion was not achieved. Fines are particles from the production process which did not form pellets, or are particles which have broken off pellets. Premium pellets must have a low fines percentage, as fines can lessen incineration efficiency along with amplify ash formed during incineration.

So what is alternative fuel, in addition to what isn’t. Fossil fuels, for instance oil and gas are not forms of renewable energy. For any fuel to be regarded as alternative the rate of consumption must be comparable to rate of replacement. Oil and gas take thousands of years owing to heat in addition to pressure under the earth to form. Our rate of use of oil in addition to gas far out weighs the rate of unrefined replacement, therefore they are none alternative forms of fuel. There are a mixture of forms of renewable energies, these include wind, solar, wave and more than a few others. At PelHeat our focus is on biomass as a alternative energy source. Biomass is any recently dead organic matter which can be used as a fuel source. This includes more than a few purpose grown energy crops, but also many resources today which are regarded as wastes. A lot of virgin wood waste, from tree surgery for instance is still sent to landfill. In the landfill the wood will decade and produce methane, a gas which is a key cause of climate change. This virgin biomass waste yet is an ideal alternative energy resource. Owing to basic processing the biomass chips can be upgraded into high value biomass pellets. These wood pellets can be used in direct burning or used to develop synthesis gas owing to gasification. Below is a video of our boiler at PelHeat combustion a range of pellets, including some biomass chip pellets.

Biomass is just one form of a biomass renewable energy. There are purpose grown energy crops such as miscanthus, reed canary grass, switchgrass along with hemp. These crops have high yields by means of low fertilizer inputs. On the other hand by way of the exception of hemp, the other crops are none food crops. On the other hand waste agricultural residues are also an ideal alternative energy resource as both food along with energy can be sourced from one crop.
