Principle of NOx formation and reduction technology and stabilization of NOx emission

Abstract

An example of the inappropriate facilities management of the Air Pollution Control Law and the Water Pollution Prevention Law had occurred in a part of enterprise which installed boiler facilities for electricity and power in 2007, and it became the socially big concern. From the viewpoint of laws and ordinances observance enforcement, investigating Committee of Ministry of the Environment and investigation of every enterprise have been performed, and analysis of the example and a future action guidance have been reported. A nitrogen oxide (it is called as NOx) is a material regulated as one of the soot of the Air Pollution Control Law. In the reports of investigating Committee of Ministry of the Environment and investigation of every enterprise, there are many inappropriate example of NOx emission. Although a principle of the NOx generation and the NOx reduction technology have been published by boiler makers and reported as various public intellect documents in the past, in this document, we will present here in order to help to obey the laws and environment subject from now on.
