SOLID FUEL COMBUSTION DEVICE, SOLID FUEL COMBUSTION METHOD, GAS HEATING DEVICE, LIQUID HEATING DEVICE, POWER GENERATION SYSTEM, AND COOLING SYSTEM

摘要

Provided are a burning apparatus of a solid fuel and a burning method of a solid fuel with improved burning efficiency, as well as a gas heating apparatus, a liquid heating apparatus, a power generation system and a cooling system. A burning apparatus 100 of a solid fuel includes a burning furnace 20 which burns the solid fuel, a gas feeding device 40 which feeds a gas containing oxygen to the burning furnace 20, and an exhaust device 42 which exhausts a flue gas discharged from a discharge port 24 of the burning furnace 20. The burning apparatus 100 further includes a control unit 46 which simultaneously controls the gas feeding device 40 and exhaust device 44 and controls a furnace pressure of the burning furnace 20.
