ELECTRICAL ENERGY GENERATION UNIT

摘要

FIELD: converting energy of air flow through underground workings and surface pipelines into electrical energy. ^ SUBSTANCE: proposed double-stage electrical energy generation unit designed to generate electrical energy dispensing with raw materials has underground working accommodating air heater and first-stage turbogenerator disposed on air flow path. Unit has four first-stage turbogenerators; air streams conflow upon passing through them and single stream arrives at inlet of second-stage turbogenerator. Diaphragms are installed at turbogenerator inlet to control air flow. ^ EFFECT: enhanced environmental friendliness of unit. ^ 1 cl, 4 dwg
