Sugimat San Miguel Arcángel caldera vapor biomasa

Europe’s largest olive marc factory is already working at full capacity with the steam boiler supplied by Sugimat

The boiler has a thermal power of 11 MW and uses the plant’s own olive cake as fuel.

PRESS RELEASE_Sugimat has designed, manufactured and supplied for San Miguel Arcángel, the biggest olive marc factory in Europe, a turnkey installation in Villanueva del Arzobispo (Jaén) formed, among other elements, by a water-tube steam boiler for the combustion of olive cake. This biomass boiler, with a production of 15 Tn/h of industrial steam and an equivalent thermal power of 11 MW, has a design of the German firm ERK, of which Sugimat has the only licence in Spain.

San Miguel Arcángel, the biggest olive marc producer in Europe, has trusted in Sugimat to develop its plant in Villanueva del Arzobispo (Jaén), to design, manufacture and install a turnkey water-tube steam boiler for the combustion of biomass, specifically olive marc. This biomass, derived from the process of extracting oil from olives, is characterised by its high calorific value.

However, this waste also presents a problem related to its ash content and its low melting point, so a specific design of an industrial multi-pass water-tube steam boiler has been developed to counteract the effect of fouling on the heat exchange body.

The boiler, with a steam output of 15 Tn/h and an equivalent thermal output of 11 MW, is based on the Eckrohrkessel design, a model of the leading German engineering and technology company ERK.  Sugimat is the only licensee of the company in Spain.

This boiler, with an operating guarantee of 8,000 hours per year, has replaced the previous equipment and allows to save an important consumption of diesel oil, since it uses the by-product of the plant itself, the olive cake, as fuel for the generation of process steam, turning the installation into a success case of circular economy.

In addition to the boiler, Sugimat has supplied the combustion system with step grate, the company’s own technology, the control system and the smoke treatment to guarantee the quality of the emissions to the atmosphere, according to 2015/2193 directive.
