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)|
|Gas natural||8,18 kWh/m3|
|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|
|Serrín||3,84 kWh/kg||2mm – 20mm|
AKTUA recommends specialist advice , both when buying a biomass boiler as for the choice of fuel.
