A biomass gasification system for producing aqueous or water gases after biomass has been carbonized is disclosed. Temperatures of a thermal decomposition and gasification furnace can be quickly and uniformly stabilized with smaller thermal loss. Reaction residuals after thermal decomposition and gasification are prevented from adhering on the inner surface of the system. The biomass gasification system comprises: a main body, a first cylindrical member, a first cut-out member, a first cylinder accommodating therein a first screw conveyor, a second cylindrical member, a second cut-out member, a second cylinder accommodating therein a second screw conveyor. The first cylinder is so constructed that it penetrates the main body, the first cylindrical member and the first cut-out member in an axial direction. The first screw conveyor, the second screw conveyor and the second cut-out member have a plurality of gasifying agent ports, respectively.

One or more techniques and/or systems are disclosed for a pellet stove system that incorporates a thermoelectric generator for efficient electricity generation. The system features a combustion chamber for burning pellet fuel, a heat exchanger to transfer generated heat to an external environment, a heat sink to transfer a portion of the generated heat to a thermoelectric generator comprising a first portion thermally coupled to the heat sink and a second portion designed to maintain a lower temperature. This arrangement allows the generation of electricity through the temperature difference, powering stove components. Additionally, the system can include mechanisms for remote monitoring and control, optimizing fuel consumption, and enhancing heat distribution, facilitated by a control unit and wireless communication module.
