GASIFIER BURNER FOR DRY COAL

摘要

PURPOSE: A gasifier burner using dry coal is provided to prevent refractory damage of a gasifier by inserting a pipe with a variable length and caliber into an oxidant supply path to adjust flame length in the gasifier. CONSTITUTION: A gasifier burner(100) using dry coal comprises a body(110) and a nozzle tip(120). Cooling water flows into the body. The nozzle tip forms the supply path of oxidant and pulverized coal. The nozzle tip comprises a discharging line(121) and an oxidant supply pipe(126). The discharging line comprises a pulverized coal moving path(122) and an oxidant supply path(123). The oxidant supply path supplies oxidant to the pulverized coal discharged through the pulverized coal moving path.
