2 KOVAN Ekoline with its headquarters in Gračanica (BIH) where the heart of Balkans steel production is situated, was founded in 1996 founded by Said Karalić. Upon its establishment, the company had only 2 employees and now employs over 300 people. The company s main production is stretched over its purpose built factory on 17,000m2 of which incorporates its own development and research centre and offices whilst the factory covers most of the area with specialist steel forming & welding machines. The company is engaged in the manufacturing of biomass pellet boilers and stoves and the production and installation of complete lines for the production and milling of biomass fuel pellets. In the last two years KOVAN Ekoline also established its own production of wood pellets near the town of Olovo, where every day there is in excess of 70 tons of pellets are produced. The production of boilers and stoves is enabled with the use of modern technology such as laser cut sheet metal and special machines for sheet metal curving, whilst extensive research and development contributes to electronic innovations in control systems and vigorous quality control and testing ensures both high quality build quality and boiler reliability and efficiency. The company is certified & recognised internationally with standards TUV, standard of ISO and all products have the CE mark and provide the latest standards EN class 5 which ensures high European quality. With our commercial service Ekoline sales cover the entire Balkans region and with a network of agents, the products are exported to all EU countries. In 2007, a subsidiary company EKOLINE international was founded specifically for marketing, technical support and spare parts distribution across the EU countries. Based in Maribor, Slovenia, the company has a dedicated 24hr/7 day customer service line available to 9 different languages. The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and electricity with less effect on the environment than fossil fuels. Using biomass fuel has a limited long term effect on the environment because the carbon in biomass is part of the natural carbon cycle; while the carbon in fossil fuels is not and permanently adds carbon to the environment when burned. 2

3 EKOLINE boilers have been designed specifically for the purpose of heating water to temperatures of up 95 C and are constructed in such a way to achieve a high degree of combustion efficiency and a optimum utilisation of heat which is produced in the boiler. The combustion efficiency degree of 96,4 % is achieved as following: The Ekoline burner is designed so that all parameters which influence the burning process of pellet can be controlled and by constructing the boilers with fire-resistant steel which resist very high temperatures adding to boiler life span. Ekoline s specially designed burner is design to operate with temperatures of up to 1200 C which contributes to the boiler high efficiency rate. ( compared to most other boilers at 600 C C ) To capture nearly all of the available heat the Ekoline boiler features a secondary burn where combustion gases re-pass the main burner in a reversible flame effect, passing the water jacket 5 times and passing through a row of heat exchangers and turbulators before exiting the boiler through with assistance of exhaust fan. The entire process of combustion the pellet fuel is controlled by specially designed electronics, which regulates all parameters that influence combustion The high degree of heat utilisation gained in the burner is achieved with the design: The construction of the boiler contains four chambers design to transfer almost all of the heat produced. The speed of the combustion of the fuel and exhaust throughput is controlled through the chambers. exchanger for 5 years but user can benefit from extended guarantees of up to 8 or 10 years subject to approval and terms and conditions. The Ekoline boiler is equipped with a digital controller that is capable of monitoring and regulating several parameters within the boiler such as, desired water temperature, flue gas temperature, fuel dosage and combustible air settings. In addition to the standard control settings user can now benefit from additional options such Lambda Probe technology which gives the user a greater level of automatic control by means of selfadjusting primary air by detecting oxygen content in the flue gases. Other devices includes the possibility to use in conjunction with Smart Phone app control, Web remote control and GMS control & error alarming as well as using with remote thermostat control. Ekoline boilers are also constructed with a purpose of eliminating condensation in the boiler and flue which is a common problem in solid fuel appliances and contributes towards decreasing the life span of the boiler construction and poor performance. The aim is to keep the produced combustion heat in the boiler for as long as it is possible, because that way more time is gained to enable heat transfer the into the water jacket more efficiently. The boilers are made of steel which is designed to operate at elevated and high temperatures, and the result is the longevity of the boilers. The Kovan standard warranty covers the user for the protection of the steel parts of the boiler and heat 3

5 IndustryLine Boilers Ekoline boilers are suitable for central heating of larger residential, business and industrial buildings as well as for heating of apartment blocks. Ekoline boilers are the perfect solution for all industry processes that use large amounts of hot water. The design of the Ekoline boilers is truly excellent and therefore its installation and subsequent use is very easy. Everyday use of the boiler is completely automated which decreases servicing time. The boiler contains a digital panel used for setting parameters for Ekoline boilers operation. Optimal combustion process achieves a high degree of utilization (96.4%) and low emissions. Unlike classic industrial boilers on solid fuels, Ekoline boilers do not require every day maintenance, so that at the very beginning, while still considering the idea of introducing central heating into industrial processes, you can count on true financial savings. Cleaning and maintenance of Ekoline boilers is simplified when compared to other boilers on solid fuels, mainly because of the high degree of energy utilization (96,4 %) the total amount of ash, after completed combustion process is negligible and it can be removed with a vacuum cleaner, which is included in the additional equipment package. How combustion works. The combustion process in the boiler starts with the input of a certain amount of pellet into the burner pot. Subsequently the igniter is activated. When heating pellets a gas is produced in the burner that ignites due to the heat produced by the igniter. After the first activation the igniter turns off and further production of gas and combustion of pellets is achieved through the heat gained from combustion of pellet bio gas and air passed by the primary air fan. Addition of pellet and air depends on the desired water temperature. 5

7 PELLET FEED SYSTEMS Pellet Feed systems are meant to transport wood pellets from bigger to smaller (integrated) reservoir. The Ekoline feed Dosing system is based on two technological features vacuum transporting and transporting with dosing screw. The system offers easy assembly, great safety features, reliability and easy operating. All devices are compatible with all pellet boilers. Pellet silo is made of special material, which prevents silo from dangerous static charge. The silo is made of two elements metal construction and special anti-static fabric. Technical details: Material: polyester, steel Dosing of pellets is manually or with blowing Measurements: 2200 x 2200 mm Height: 2000 mm Minimal space height: 2150 mm Diameter of bottom hole: 250 mm Volume: it provides storage space for up to 3.5 tons of pellets 3 Feed Systems available: Vacuum Boot Turbine with 15m Anti-Static Vacuum Tube 3.0m Rigid Screw Conveyor Floor Mounted Screw with vacuum feed Pellets are supplied via pneumatic or rigid tubes from the main fuel silo where it is possible to store up to 1 year or more of pellets and from here the pellets move to the boilers burner. The dosing system maintains a sufficient amount of pellets in the intermediate container to ensure a smooth operation of the boiler over a longer period. Silo Boiler Room Main silo available in three versions, 16m³, 31m³ & 46m³. The Ekoline silo provides cost effective and very reliable operation with low maintenance and down time caused by blockages. 7
