Small capacity biomass firing steam boilers

JSC “GANDRAS ENERGOEFEKTAS” offers boilers and complete plants for biomass with high moisture content (up to 12 % on dry base or 55 % on wet base) burning. It is possible to burn in the boilers animal origin waste, such as chicken manure mixing it with wood chips. To determine possibility of burning one or another king of the waste, manufacturer make test at his factory site, during which delivered from the customer waste is burning, adding to it certain quantity of wood chips. During testing engineers are monitoring the processes inside of the boiler, temperature in the combustion chamber, emissions level and so on, analyzing received information, after what they give recommendations concerning this type of fuel burning, and, if it is required, boiler construction modifications.
