New biomass boiler heats greenhouses while reducing greenhouse gas emissions

Axis Technologies, a subsidiary of Lithuania-headed Axis Industries Group, has announced that it has installed a 6 MW biomass boiler for Ūkininkas Audrius Juška at its new greenhouse installation in Anykščiai, Lithuania. It is the second order for Axis Technologies from the same company.

Worth around EUR 2.5 million, the new biomass boiler plant will heat 6 hectares (ha) of newly installed greenhouses for Ūkininkas Audrius Juška in Anykščiai. The company is a major Lithuanian producer of fruit and vegetables.

This is the second biofuel energy project we’ve implemented at this farm. We’re glad that the farmer, whose business is expanding and whom we can confidently call our partner, once again trusted us to provide him with specific greenhouse heating solutions. We installed a comprehensive biofuel energy solution that will save money and keep the environment healthy, said Giedrius Vaitkevičius, CEO, Axis Technologies.

The connection of the 2 MW biomass boiler plant, built several years ago by Axis Technologies and the new 6 MW plant will ensure integrated heating infrastructure management. The new boiler plant runs on shredded wood and logging residue. These are fed into the plant from a fuel storage unit equipped with moving floors and adjacent the boiler house. An emergency fueling system has been installed as well.

In addition to the boiler plant, a 1 200 m3 buffer tank was also built to guarantee the stable operation of the plants. The buffer tank enables the storage of heating energy during the day when the greenhouses need it the least and for its use when the greenhouses need more heat. The company also installed two economizers that have enabled increases in plant output by 0.3 MW while consuming the same amount of fuel.

According to Vaitkevičius, one could also say that Axis Technologies’ products now indirectly impact a majority of Lithuanian people, who purchase Juška’s products from major retail chains.

Both the ecological and economic benefits of the plant are clear. Natural gas energy prices are currently at EUR 27 per MWh, while prices for biofuel energy are only EUR 12 per MWh, said Vaitkevičius.
