Sustainable architecture: biomass boilers choice

When designing and constructing sustainable architecture, one of the most important challenges is the HVAC system .
In sustainable architecture as important is the orientation, isolate well as producing heat / cool efficiently using a renewable energy source .

Biomass boilers , they are particularly suitable for sustainable houses, for the production of heat. These are composed of a burner , just like gas or diesel boilers , which burn only natural products, biomass, and like her sisters, conventional gas or diesel boilers , there are multiple productions.


Caldera Diesel, GLP (propano, butano, gas natural) 90 %
Caldera condensación Gas natural, GLP 106-109 %
Caldera biomasa Pellets, hueso oliva 75 %
Caldera de gasificación de leña Vigas de leña 92 %

Another important feature is the product burn. When we use gas boiler or diesel fuel has a virtually homogeneous properties regardless of where and how we buy it , because its composition is similar , all the diesels have the same calorific value , so does when comparing different sources of natural gas , or butane .

They are derived from a raffinate homogenized properties , including heating value, ie the amount of energy we get in combustion.

Combustible PCI (poder calorífico)
Gasóleo 9,98 kWh/l
Gas natural 8,18 kWh/m3
Butano 12,78 kWh/kg
Propano 12,93 kWh/kg
Pellets (promedio) 5,23 kWh/kg

And this is where there is a big difference with the combustion of biomass , depending on its composition vary significantly calorific value and therefore performance, and ultimately their economic performance. The pellets are not all the same , since the woods of which are composed neither are , so a pellet produced pine will not have the same calorific another oak wood composite .

An effective way to avoid mistakes is biomass produced from olive stones , first because its shape is different from any pellet is distinguished by the naked eye , second because it has one of the highest specific heats ( heat potential kcal/m3 contained therein ) . Other advantage is that we make sure that it is a sustainable product , it is a product derived : they will not cut down trees or burn them to manufacture olive peles bone .

Hueso aceituna 5,58 kWh/kg 2mm – 5 mm
Cáscara de almendra 4,07 kWh/kg  25mm-30mm
Pellet 5,00 kWh/kg 6mm
Serrín 3,84 kWh/kg 2mm – 20mm
Orujo 4,54 kWh/kg 1mm-5mm
Astillas 4,07 kWh/kg 10mm-50mm

AKTUA recommends specialist advice , both when buying a biomass boiler as for the choice of fuel.
