Simply compacted wood. Wood pellets are generally made from compacted sawdust by an
Of course. Currently, over 10 million certified tons of ENPlus pellets are produced in 45 countries from Canada to Malaysia.
Certainly, this unstoppable global trend may vary locally.
Certainly, it will remain far more stable than the price of fossil fuels, or will have only moderate increases. Precisely the large number of quality certified manufacturers, as well as distributors, allow competition and price stability.
The marketing of fossil fuels (gas, oil) is in the hands of a handful of companies, a fact which prevents fair competition in the market.
Of course. Certified pellet must show ENplus label, the only European label that guarantees a stable quality according to EN14961-2 standards.
ENplus A1 superior quality pellets have lower percentage of ash, lower moisture and come from debarked and untreated wood. It is inexpensive and available in many establishments, from bags of 15 kg in retailers to home delivery tanker.
Skimping a couple of cents in the quality of pellet, burning uncontrolled fuel that may contain chlorine, sulfur or tar, is like filling with agro diesel the tank of a gasoline vehicle.
Exactly like a fossil fuel boiler, with slight differences:
– It is much more environmentally friendly: no CO2 is added into the atmosphere and, if combustion and fuel quality are good, hardly produces particulate emissions
– It is much cheaper: the kWh generated by biomass costs half of that produced by fuel oil or propane
– It generates ash, which must be removed at certain intervals. In the case of BioCurve boilers up to 50 kW, we recommend emptying the ash once a month or every 500 kg of pellets burned, while it is desirable to verify, once a week, that ash generated has fine grain. This ash is a natural product, and may even be used as fertilizer
– is required, like fossil fuel boilers, annual maintenance by qualified personnel, that takes slightly more
A biomass boiler, when burning a solid fuel, requires a little more maintenance than a fossil fuel boiler. It is advisable a periodic visual inspection, to verify that the generated ash is fine.
Likewise, we remind you that a maintenance book, supplied with the boiler, must be filled out by the corresponding technical service with the operations developed according to the terms established in it. The guarantee, among other conditions, is valid if the maintenance is carried out
following the instructions supplied with the boiler.
If burning of wood pellets certified to EN 14961-2 class A1 (e.g. ENplus A1), there is no requirement to specify the chemical composition of the condensate, according to British Standard MCS008 issue 2.2.
In most of local legislations, it can be disposed to the domestic sink without any further treatment (pH~7;LI=-0.8 ).
