NOVELTY - The apparatus (100) has a stem structure that is pressed in a container where the biomass compost of the billet state is compressed in the container, and extruded to a pellet form from the dice hole. A manual handle is provided for inserting the stem structure in the container so that biomass compost is packed into the container. The stem structure is attached to the container through a spring where stem structure is returned to an original position according to the elastic force and deflection force of the spring after stem structure is packed into the container.    USE - Biomass compost fuel-pellet manufacturing apparatus for use in home.    ADVANTAGE - The household garbage can be easily made into a dry compost pellet. The manufacturing cost of the biomass compost fuel-pellet manufacturing apparatus is reduced. The safety of the biomass compost fuel-pellet manufacturing apparatus is ensured. The structure of the biomass compost fuel-pellet manufacturing apparatus is simplified. The biomass compost fuel-pellet manufacturing apparatus is environment-friendly.    DETAILED DESCRIPTION - A piston-shaped stem structure is packed into a container in a billet state so that the biomass compost is pressed, and injected in the container along the specific direction. A double structure fermentation unit is provided with an inner case container having a perforated filtration type stirrer. An organic refuse and humus are mixed in the inner case container so that pulverization element is formed where 50 to 80 weight% of water content is fermented. The obtained fermented material is taken out of the inner case container with a perforated filtration type stirrer, and dried. A dummy block structure is positioned at the front portion of the stem structure. The biomass compost is injected in an insertion opening structure (20). The injected biomass compost is maintained in a billet state. A pellet is extruded to a cylinder structure through a dice hole. A disposer performs radioactive decontamination process of organic refuse and biomass. The pulverization element and humus are washed with water, and decontaminated where decontaminated pulverization element and humus are pulverized by the disposer. A heat-resistant outer container is provided with a cock stopper having an outer wall where outer wall is made of heat resistant material. An ignition unit is provided for accommodating the polypropylene raw material in a perforated metal pellet-form capsule. A boiler is provided for driving steam turbine at the high temperature and vapor pressure. A private power generator is provided for converting high velocity revolution kinetic energy generated with the steam turbine, into the high output electrical energy. A heat exchanger is connected with the vapor discharge port of the steam turbine. The heater is provided with a built-in boiler.
