KWB And Hcib present his official certification for the use of the bone of olive in the boilers of biomass

KWB has become the first company that manufactures biomass boilers that officially guarantees the use of the olive bone on their computers. To have a proper combustion and minimal emissions, the company made a classification of the main components that must have the bone of the olive.

To certify it, a group of representatives from HC engineering and KWB have toured the South of Spain to meet olive groves and analyze the operation of the boilers that already use this system. In addition, KWB Austrian facilities has studied olive bone for four years to take advantage of all the resources offered.

As a result of the collaboration between HC engineering and KWB was an exchange of information on the performance of biomass boilers that finally began to study in Austria in the year 2008 with the completion of several tests.

Two years later decided to starting up this study with a project of field in actual installations in Andalusia. So 15 monitors were installed in facilities that consume various types of bone in different models of KWB biomass boilers. In addition, also chemical studies of bone is often done to try to establish some parameters of its characteristics and its quality.

"The conditions of olives make it very easy to work with them, how difficult is to control the quality of the bone. We try to explain to the client what is good and what is bad, since the market right now is very broad and difficult to standardize. Bone dry and clearly is very good while dark and smelling bone creates problems, "said Miguel González, Manager of Hcib.

The year past KWB contrasted results with the entities responsible for the Biomasaud project in order to ensure the quality of the bone to be used safely. Finally, in June of this year has been certifying the use of the bone of the olive as fuel in biomass boilers, joining burning wood chips and pellets in such boilers.

“Have checked that the bone of the olive works with some standards of quality. The certificate that give is very tested and based. We look for the hygiene of the customer first of all”, affirmed Miguel González, that recognised that the prudence has been the basic pillar of his gestión.

The studies realised have had like consequence the typification of the components that has to have the bone of the olive for a suitable combustion and some minimum broadcasts. In said typifications have stood out the content of fat, the humidity, the fusibilidad of the ashes and the content in fine, chlorine and sulphur.

HC engineering and KWB objectives have focused on establishing minimum standards of quality and sustainability that provide security to the customer and guarantee a good result from the use of the bone of the olive in biomass boilers.

To llevar the normalisation of the bone of the olive transferred the results obtained in the investigations to the technical committee of solid biofuels of Aenor to develop a norm JOINS on specifications and classes of bone and shells. The final aim has been the creation of a stamp of quality.

Although Spain resists to the innovations, as it explained Miguel González, the biomass is opening way little by little thanks to his advantages, since it treats of a clean power, near, comfortable and economic.

Harald Krasser, KWB representative, explained the importance that Spain take advantage of their resources. "We have a great potential in the South of Spain and it is necessary to use it. Normally olive bone is used in large boilers to produce electricity and we seek to use in small boilers. You have to move the market of the bone,"he said.

Regarding the economic saving, the own Harald Krasser explained that in Spain produce near of 600.000 tonnes of bone of olive and that by each kilogram save until 0,80 cents, what supposes a saving until 50.000 euros to the year. “Two kilos of huesode olive generate the same heat that a litre of diesel. Two kilos of bone cost 0,20 cents, the litre of diesel, a euro”, explained Miguel González.

KWB and HC engineering representatives highlighted the convenience of this type of boilers, since we only require a single cleaning of ash per year (on two occasions), and new technologies allow its control through a Smartphone, offering the possibility to the customer manage it without being physically in the place where the boiler is installed. "It's more environmentally friendly. The initial investment to install these boilers is greater, but is able to pay for itself in just five years,"said Miguel González.
