The Enerstena Company Group Heating Your Business! The Enerstena Company Group, operating in the energy market, actively follows the pollution reduction policy, and creates solutions for efficient heat generation while protecting the surrounding environment. The biomass combustion equipment manufactured by the company has always conformed to and has even exceeded the requirements of the directives of the European Union regarding the concentration of pollutants contained in combustion products. The biomass combustion equipment which is designed and manufactured by the Enerstena Company Group features the full combustion of biomass, i.e. materials with a particularly low emission of nitrogen oxygen and carbon monoxides (NO X and CO). All of the solutions designed by the Enerstena Company Group for the purpose of efficient heat generation are directed towards caring for a green environment. The projects to be carried out by the Enerstena Company Group are realised from the initial idea to the key. Moreover, the company provides operation and automation services. Our clients are heat suppliers and industrial companies. We are proud of the projects we have realised and our clients are satisfied that they possess a competitive energy source.

4 CALIDUM EMBER FURNACES The furnaces of the Enerstena Company Group are designed in accordance with the latest technologies. The biomass combustion furnaces operate under the gas generation principle, with inclined moving grates. The combustion process in the furnace is controlled according to the amount of oxygen in the flue gases. The furnace masonry is made from heat-resistant materials. ADVANTAGES OF THE CALIDUM EMBER FURNACES: the furnaces are designed for the combustion of both dry and moist (humidity of up to 55 percent) fuel; the furnace frame is water cooled; low emissions of nitrogen oxide and carbon monoxide (NO X and CO) due to complete combustion of biomass; the combustion is controlled according to measurements of the CO and O 2 in the flue gases; suitable for burning various types of biomass.

6 UP TO 150 MW ECONERG FLUE GAS CONDENSERS The Enerstena Company Group designs and manufactures flue gas condensers for biomass boilers with a capacity of up to 150 MW. Using the flue gas condensers, manufactured from stainless steel, it is possible to essentially increase the heat generation while burning the same amount of fuel. This is due to the deep cooling of the flue gas and the condensation of water vapour in the flue gas condenser. Through this process, additional heat amounting up to percent can be obtained. Such operational indicators of the flue gas condenser are reached due to the non-dried wood that is combusted in the biomass boilers, so that the major part of the combustion heat is used for the evaporation of the fuel s moisture. In the flue gas condensers, contrary to the boiler, the heat is recovered and is used. BIOMASS BOILER HEAT CONSUMERS BIOMASS ADVANTAGES OF THE ECONERG FLUE GAS CONDENSERS: low hydraulic and aerodynamic resistance low electricity costs; efficient heat exchange in the flue gas condenser; flue gas condensers are easily adjustable to all types of boilers; district heating water is heated without an intermediary heat exchanger; additional heat can be obtained amounting up to 30 percent of the boiler s capacity; efficient condensate cleaning system.

EFFICIENCY OF THE BIOMASS BOILER PLANT WITH THE FLUE GAS CONDENSER BIOMASS BOILER PLANT FLUE GAS CONDENSER BIOMASS BOILER PLANT WITH THE FLUE GAS CONDERSER EFFICIENCY 85 % EFFICIENCY % EFFICIENCY 115 % Heat obtained in the flue gas condenser. We guarantee a temperature difference of up to 3 C between the incoming water and the outgoing flue gas. The main indicators of the flue gas condenser are as follows: the thermal power and electricity consumption necessary for the generation of 1 MWh of heat are recovered from the flue gas; these indicators are always visible on the operator s PC. The flue gas condenser s control system is fully automated, so that the equipment operates automatically without the permanent supervision of the operator. All of the technological measurements, the state of the equipment, events, failures and faults are displayed on the operator s control panel and the operator s workplace PC, where all of the data is archived. The flue gas condenser is equipped with a condensate treatment and neutralisation system, with drainage of the formed sediments. The condensate treatment, neutralisation and drainage system has been developed by the specialists of the Enerstena Company Group and operates in automated mode. The company s long-time experience has enabled this filtration system to be designed so that it will operate reliable and require minimal maintenance from the servicing staff.
