In a Biofuel (Bio-liquid) heating system using a Tigerloop Bio, all fuel passes through the automatic fuel de-aerator, which effectively removes all gas/air bubbles from the system. This eliminates burner pump and nozzle problems associated with gas/air in the fuel.
Own two-pipe circulation
A burner pump delivers the same amount of fuel irrespective of what is actually needed for combustion. In the case of a normal domestic burner, only 5% of the delivered fuel is actually burned in combustion. The remaining 95% is transported by a two-pipe system back to the tank. With a Tigerloop Bio automatic de-aerator, no fuel will be transported back to the tank. The fuel that is not burned in combustion is lead back to the Tigerloop Bio where it is de-aerated again and again automatically. For this reason only the amount of fuel to be burned in combustion is sucked from the tank.
A one-pipe system with Tigerloop Bio increases the Burner pump capacity. Moreover, the fuel is actually preheated to at least room temperature as friction in the burner pump generates heat. This eliminates problems with cold fuel giving cleaner combustion and reduced fuel consumption.
The flow of fuel in a one-pipe system is minimal due to the fact that only the amount of fuel burned needs to be drawn up from the tank. For this reason very little dirt/sludge is transported from the tank. This reduces the risk for clogged filters and burner nozzles. Filtration is more effective, soot build up is reduced and filter life is extended.
