Peat briquettes
Briquettes are another form of the peat fuel. They are produced by specialized peat briquettes plants. The size of the briquette is abt 170 x 70 X 35 mm. Total moisture of the briquettes has to be below 16% and ash - below 13%. NCV of the briquettes is usually about 16,0- 16,5 GJ per mt. It has always been difficult to achieve NCV at 17,0 GJ per mt, which nevertheless has been asked by the end users. Sulphur has to be below 3% and Nitrogen - below 2,6%. Ash melting temperature is abt 1200 degr C. At the moment peat briquettes are produced and used in Finland, Sweden, Ireland, Byelorussia and Russia. Quite a lot of peat briquettes and sod peat was produced in Estonia, but after Estonian peat lands and peat production has changed the owner the energy peat production in the country was practically stopped. Some quantities of peat briquettes are exported from Byelorussia to Sweden. Logistics chain in this case is transportation of the briquettes by hopper wagons to Lithuania or Latvia and after that the briquettes are taken by sea to Swedish ports. It is very important for the briquettes to be treated by gasoil in order to decrease the dust formation during loading and unloading.
