Long-term experience of Swedish and Finnish energy producers demonstrates that the use of wood and peat mixture as fuel slows down the wear and tear of boilers, compared to using wood chips only. Therefore, such a mixture is chosen in order to improve and prolong the longevity of boilers.
The energy value of wood and peat is very similar:

“Vapo Oy”, one of the founders of “Bioenergija LT”, has been working with great success in Scandinavian countries for many years. Finland and Sweden are among the leaders of bioenergy generation, therefore industrial production of this type of energy has much older traditions in these countries than in Lithuania. Various types of boilers are used in these countries, and their installed capacity can be as high as 100 MW. Some of the boiler types are known and used successfully by Lithuanian heat producers. One of the most popular is the “fluidised bed” boiler, used for combusting the mixture of milled energy peat and wood chips. Many of the boilers designed to be used with biofuel on the basis of wood chips can introduce energy sod peat to such mixture with high efficiency. Experience shows that such a modified mixture increases the amount of generated energy.
