System Specification: 7 MW hot water boiler, design pressure 6 bar(g).
Fuel: 2015 – 2018 straw bales (Heston) and from 2018 olive crops.
Fuel Feed System: Stoker.
Justsen Boiler Type: Hot Water Boiler JUE-GVB.
Special Equipment: Initially, the boiler was designed to accommodate straw combustion, where straw bales are lifted with a crane from the storage room onto a straw shredder from where the cut straw is fed directly into the boiler. The inside of the combustion chamber had to be reinforced with a stainless-steel alloy SAF 2205 to eliminate low-temperature corrosion and, thus, protect the boiler from corrosion caused by Chlorine that straw contains.
Flue Gas Cleaning: Justsen designed bag filter.
