The task of investigation was development of main approaches for biomass preparing and processing for use it in industrial furnaces and boilers instead of natural gas. The direct combustion of sawdust and sunflower husks and gasification of different kinds of biomass were studied. The burnout time of sawdust and sunflower husks particles was defined and demands for fuel preparing for use it in rotary kilns were elaborated. Special burners and heat regimes for sunflower husks combustion in rotary kilns were developed and implemented. Original technology of biomass air gasification was proposed and studied. It was shown, that producer gas has low calorific value sufficient for use it in boilers and engines. Industrial gas generator of 1,8 MW capacity and dual fuel burners for joint or separate combustion of producer and natural gas were developed and implemented at steam boiler. Technical solutions piloted in industrial scale could be efficiently applied in manufacturing sectors and energy sector.
