Title: Denitration control system for incinerator of waste
Inventor: KIM GYU SIK
IPC: F23G5/00
Filed: 1998-11-13
Abstract: PURPOSE: A denitration control system of an incinerator is provided to prevent the environmental pollution by developing the control technology to remove nitrogenous compounds(NOx) in a process of incinerating industrial waste and waste matters from home.
