ÖkoFEN pellet heating - 96% less particulate emissions

The use of modern pellet heating systems reduces particulate emissions!

A study undertaken by the University of Linz in Austria has found that particulate emissions are a problem exclusively of older solid fuel heating appliances. However, the proportion of these old wood heating systems in use remains very high.

Professor Reinhold Priewasser of the Institute for operational and regional environmental economy at the University of Linz said "It is obvious that we cannot equate the particulate emissions from modern pellet heaters to classic solid fuel heaters. The emissions of the new devices are over over 90% lower. If we want to reduce particulate emissions, we must replace old wood boilers with modern pellet heating systems."

The particulate output of an old wood heating might typically be 148mg/MJ, but a modern pellet boiler produces values of approx 10mg/MJ. Particularly efficient and pollution free are ÖkoFEN wood pellet heating systems: tests in Wieselburg have established that the ÖkoFEN pellet heating system produces particulate emissions of 8mg/MJ.

With the condensing wood pellet boiler technology developed by ÖkoFEN, wood pellet heaters have become even more efficient with values of 5mg/MJ being recorded. By way of comparison, an oil boiler (as measured by Austrian Federal Office for Environment Protection) produces around 3mg/MJ.

In Austria the maximum permissible particulate emissions of automatically fed small firing plants is 60mg/MJ. The particulate emissions the ÖkoFEN pellet boiler are proven to be far below the legal limit: with the standard boiler the average emissions are typically 87% under the legal limit. With the condensing boiler the average emissions are 92% under the legal limit.

Swiss investigation concludes: the particulate emissions from automatic combustion of wood is 5 times less dangerous than Diesel exhaust!

The extensive research of Dr. Norbert Klippel and Dr. Thomas Nussbaumer, ETH Zurich, provide interesting results. Fine particulate emissions from the burning of a natural material such as wood in an automatic combustion process result predominantly in the production of inorganic compounds and salts. When examined, this fine particulates were found to exhibit a cell toxicity approximately fivefold less than that of Diesel soot.
