Austrian firm KWB pioneers the use of pits in production of domestic heating
Olive pit fuel has excellent properties due to its high density, humidity of 15 percent and elevated calorific content. Because of these qualities olive pits are gaining greater importance in the domestic and residential sectors in the supply of hot water and central heating. An Austrian firm, KWB, has now become the first supplier of biomass boilers to officially guarantee customers over the use of pits in its Multifire brand apparatus.
„Other brands are using pits as well, and the makers allow for the use of pits in their apparatus, but only KWB offers a guarantee with the corresponding technical data, thanks to the excellent results achieved in their research,“ says Miguel González, director of HCIB Engineering and Biomass, official distributor for KWB boilers in Spain.
KWB offers a three-year full-service maintenance guarantee and up to eight years for the replacement of heat exchangers.
The Austrian company has been working to develop olive pits since 2005, when it began to install its first biomass boilers. Members of the board and journalists from Austria, Germany and Italy recently traveled to Jaén, the Andalusian city at the heart of the country´s foremost olive-producing region, to see how the use of pits in biomass heating units works.
This year, a residential home for senior citizens in Matamala de Almazán, Soria, installed two KWB biomass boilers that will allow it to meet its energy needs for heating and sanitary hot water.
As well as olive oil production, Jaén is the leader in Spain in the use of thermic energy produced via biomass, with 26 percent of Andalusia´s entire consumption (158.52 kilotons of biomass) and more than 4,000 thermic installations, 20 percent of the regional total.
One of the newest such plants has been opened by Probiosur, in Baeza, a cooperation between Aceites del Sur, Coosur – which provides the pits – and García-Munté Energía, which has a long history in the renewables market and is now promoting olive fuel for heating. Its processing capacity is 50,000 tons of pits a year and investment now totals over a million euros, 25 percent of which has come through a regional government subsidy.
„Olive pits present an opportunity for employment that is not delocatable, that is to say it has to be carried out in our mountains and in this sea of olive groves in Jaén,“ says the provincial assembly leader, Francisco Reyes.
