The strategy involves a staged combustion, where a hydrocarbon fuel added in the second, fuel-rich stage provides hydrocarbon radicals which can react with and finally reduce the NOx formed in the first, fuel-lean stage, such that NOx formed in the first stage reacts with small hydrocarbon radicals present in the second stage combustion, finally leading to N〓, and to HCN which in turn is converted to NO or N〓. Understanding of the chemistry in this second reburning stage is clearly a key to understanding and optimizing reburn technology.

目前消除NOx的主要方法是向燃烧的废气中加入某些化学物质使其重新燃烧(Selective Noncatalytic Reduction of NO processes，SNCR)，RAPRENOx过程是SNCR的主要方式之一，其实施是向燃烧产生的废气中加入异氰酸，异氰酸在高温下经一系列包括NCO的自由基反应，可以从燃烧的废气中迅速除去NOx化合物。
