COAL GAS FIRE POT SALG TAP HEAT SYSTEM

摘要

PURPOSE: A system for heating slag tap of coal gas generating apparatus is provided for effectively removing slag solidified around the slag tap by supplying determined amount of oxygen into the apparatus through the slag tap heating nozzle in order to maintain the temperature of slag tap above the pour point. CONSTITUTION: The system for heating slag tap of the coal gas generating apparatus comprising the gas generating apparatus (110) to transfer coal into combustible gas; the slag tap (112) equipped at the inside of the apparatus to flow out and treat the slag; and the supplying line (114) to provide oxygen, nitrogen and fine coal into the apparatus has at least one of heating nozzles (140) placed at lower portion of the slag tap and passed through the gas generating system in order to continuously maintain the temperature of slag tap above the pour point and control it by regulating the amount of oxygen flowing into the apparatus via the heating nozzles.
