FIRING DEVICE FOR SOLID FUEL BOILER

摘要

PURPOSE: A combustion device for a solid-fuel boiler is provided to combust solid fuel in a short time by simultaneously discharging sludge and supplying air using a transfer screw. CONSTITUTION: A combustion device for a solid-fuel boiler comprises a fuel supply part(110), air house(120), a combustion chamber(140), a screw assembly(130), and an ignition nozzle(150). The fuel supply part delivers high pressure oxygen and solid fuel. A turbo-blower(122) of the air house supplies high pressure oxygen to the fuel supply part. One end of the combustion chamber is built in the air house. The combustion chamber is combined with the fuel supply part in order to burn the solid fuel . A coolant water feeder cools the transfer screw. The drive part supplies the drive power of the transfer screw. The ignition nozzle is connected to a power supply assembly(170) and is installed in the combustion chamber. The ignition nozzle burns the solid fuel .
