In 2015 the company UAB “Enerstena” under the contract carried out a reconstruction of boiler plant by installing a biomass (woodchip) 8MW (12t/h) steam boiler and other auxiliary equipment. As a dairy company, we consume large amount of heat for production, and this project provided us with more economical and environment friendly method of obtaining energy. The transition from the use of natural gas to renewable energy resources has substantially reduced the cost of production, which gives us an opportunity to provide greater support for local milk producers and increase the volume of our production in the nearest future. We are grateful to UAB “Enerstena” for the successful implementation of the project.

UAB Žemaitijos Energija was building and installing a 9.5 MW biofuel boiler house in Telšiai, which is connected to the Telšiai heating networks. Žemaitijos Energija operates as an independent heat producer; and UAB Enerstena was chosen by us as the general contractor for building the boiler house and producing the related technological equipment. Previously, this company had implemented other large energy projects in this region, and when choosing the supplier for the equipment we took into consideration the fact that UAB Enerstena designs and manufactures its own biofuel water heating boilers, condensing economizers and all of the other components installed in the boiler house, which is meaningful when operating and servicing the equipment. We are happy with our choice, and value the high qualifications of the experts of UAB Enerstena in the area of developing biomass combustion technologies. The company has not disappointed us – the technologies installed by Enerstena have met our expectations, and the operational costs and operation efficiency ratios conform to the limits foreseen in the planned Technical Task. The team of professionals at UAB Enerstena has completed their tasks in a timely and qualitative manner. There were no troubles at all, and we can assuredly recommend the company to others.

We are glad that our boiler houses were reconstructed by the company from Kaunas. By implementing projects for two biofuel boiler houses with a total capacity reaching up to 50 MW, we could significantly reduce the heating costs for the residents of Kaunas, which are now one of the lowest in Lithuania. By producing cheaper heat, these boiler houses (one – in the Petrašiūnai Power Plant; and the other – the Inkaras boiler house) offer serious competition to independent heat producers and prevent them from increasing their prices unreasonably.

In 2014, UAB “Enerstena” reconstructed the boiler house of PSIA “Ventspils siltums” and installed a 26 MW flue gas condenser for the biomass boilers. The installation of the flue gas condenser has made it possible for our company to save fuel, and therefore increase the efficiency of the thermal energy generated by our woodchip boilers. The humidity level of the woodchips is approximately 40-50%, which is turned into water vapour during the combustion process and is then discharged into the atmosphere. With the help of this new equipment, the heat from the vapour is returned back to the system. This means that the boiler has to operate less frequently to heat the water until the set temperature is reached for releasing it into the heating system. Thanks to the condenser installed by UAB “Enerstena”, the efficiency of our boiler house has increased by an average by 21%, which means that there is a lower consumption of the woodchips used to generate the necessary amount of heat. Also, after the implementation of the project, the amount of hard participle emissions in the flue gas was reduced and the environmental quality of the emissions was significantly improved. We are pleased with the results of this cooperation and appreciate the high quality of work carried out by the UAB “Enerstena” company.

Recently, we have completed the construction of the already second biomass plant and we intend to do without gas. In this way we will reduce the cost of heat necessary for production process. To implement both projects we have chosen ENERSTENA, because we trust the team’s professionalisms and knowledge of the works they perform. In 2010 ENERSTENA installed us 18 MW (26 t/h, 25 bar steam) biomass-fired steam boiler. The boiler itself was manufactured and bought abroad at that time. In 2014 ENERSTENA decided to be the first company in Lithuania to manufacture steam boiler. The innovative company has perfectly coped with this challenge. To produce paper and cardboard, the biomass boiler with 10 MW power (14 t/h, 20 bar steam) and 2 MW flue gas condenser were installed. ENERSTENA has proved that the equipment manufactured in Lithuania and the use of renewable energy sources is possible even in the most complex technological processes. We are proud that the first Lithuanian firetube steam boiler operates namely in our company.

The planned completion date of the project was 30 June 2014, however, ENERSTENA made the effort, found inner reserves and completed the construction works well before the planned date and the quality of work did not suffer from that. ENERSTENA manufactured, installed, tested in the State Enterprise Visagino Energija plant and launched the second 8 MW biomass-fired water boiler with furnace for production of heat and hot water on 04 April 2014. Wider use of renewable energy resources (wood chips) still cheaper at the moment than natural gas at the SE Visagino Energija biomass plant, evaluating biomass price, enables reducing the heat production costs and thus the costs of heating for Visaginas residents and significantly reducing greenhouse gas emissions,  at the same time contributing to the environment preservation. ENERSTENA carried out the works according to the approved work schedule; it performed the works in a qualitative manner and completed them prior to the deadline. All the assembled equipment complies with the strictest quality safety and reliability requirements; the relevant warranty is granted to it and its construction  works.

In 2010 “Enerstena” designed, manufactured and assembled flue gas condenser for us, which, in my opinion, is one of the most successful investments, helping to significantly increase the efficiency of thermal energy production. It produces up to 25% of thermal energy, which used to be released to the environment together with the smoke and heat the air. In 2014 “Enerstena” built a new 10 MW vertical biomass boiler. The new boiler is incomparable better than the two existing ones. Here everything is automated and controlled by computer. We only have to bring fuel on time and change the ash container.

Taking into account the increasing prices of energy resources in Lithuania, high intensity of electricity and thermal energy consumption in manufacture and caring for the surrounding environment, “Žemaitijos pienas” initiated the construction of power generation plants using the renewable energy resources. As the carried out study has revealed, currently one of the most economically based and acceptable options is wood-fuelled steam boiler. To implement this project, “Enerstena” was selected, having many years of experience in the area of manufacture of equipment for biomass plants and we are satisfied with its work. The object’s operation started from 10 April 201, although we were able to enjoy the project’s efficiency and benefit already in March, when the launching-coordination works started and the steam was released to the production process. The result of our choice is a smoothly functioning 10 MW steam boiler room fuelled with biomass, cleaner air in Telšiai and preservation of the Earth for future generations.

I started my farming activity on 21 July 1991. At the moment we specialise in floriculture and cucumber–growing, with a total area of 35000 sq. m, including 17000 sq. m of greenhouses which are used for growing short-fruited cucumbers, and 18000 sq. m used- for various potted flowers. Climate controls, fertilization and heat are all controlled by computerised equipment. The greenhouses are operated continuously throughout the year, and the heating needs specialist equipment. Following a recommendation, we chose UAB Enerstena to produce our boiler system. Professionals of the company came to me and, having analysed the situation, designed and produced a gas-combusted boiler of 4 MW, to the exact specifications of our agreement. It works perfectly in my farm, and I am very glad of it.

Both the economic aspects and ecological issues prompted to shift to biomass. We have discussed the applicability of biomass in our business, carried out economic analysis and the obtained results have shown that we can produce heat at a half price. Moreover, we will reduce the dependence on unpredictable gas prices. Another important issue was environmental – in addition to the main biomass supplier we also intend to involve local farmers. We would like to propose the region’s farmers to clean drainage ditches, forests and to sell this whole wood to our company. “Enerstena” performs the works from idea to key in the energy field. The works include design, equipment manufacture, object construction, testing, commissioning and operation works. The ability to get all this from a single source saves a lot of time and money.
