The invention discloses an environmental-protection energy-saving drum biomass coal making process. The coal making process comprises the steps of: obtaining high-temperature fume by combusting associated gas generated during biomass coal making process for discharging heat; exchanging heat with the high-temperature fume by using a drum carbonization device to form low-temperature fume; discharging the low-temperature fume after the low-temperature fume is processed by a drum drying device; after starting a system, providing heat energy for biomass coal making by combusting the associated gas; and directing pressing biomass into coal at high temperature after the biomass is processed by a carbonization device. The biomass coal making process is completely automatically controlled. An environmental-protection energy-saving drum biomass coal making device comprises a material transmission system, a material drying system, a material carbonization system and an associated gas combustion waste heat recovery system, which are connected mutually, as well as an automatic control system which is connected with the systems electrically. The invention has the advantages of reasonable structure, high energy utilization and conversion rate, no external energy supply in the biomass carbonization process, no harmful gas emission, energy saving, environmental protection, obtained high-quality biomass coal, no overburning, no half baking, high heat value, complete automatically-controlled process and the like. The invention can be widely used in biomass coal making processes.
