Abstract
Nowadays, global warming is the main environmental problems all over the world. The air pollutants mainly from the burning of fossil fuels and coal in power plants, transportation, and automobiles. There are release major point emission of the atmosphere. The nitrogen oxides are the most relevant for air pollution that contribute to the formation of photochemical smog and acid rain. Numerous methods have been studied to eliminate the nitrogen oxides such as the use low-nitrogen fuels technology, the selective catalytic reduction (SCR), wet scrubbing. The aim of this research is investigated non-thermal plasma (NTP) techniques offer an innovation to eliminate both nitrogen oxide (NOx) and soot emissions from combustion. This study is used to selectively transfer input electrical energy to electrons without expending this in heating the entire gas flow which creates free radicals in the flue gases. The simulated flue gas from combustion process is applied to the system. The results showed that the prototype of nonthermal plasma system is shown the highly efficient of NOx removal was achieved. However, the optimised of NTP operating conditions are required to enhance the NOx reduction activities.

Summary
Nitrogen oxides are toxic emissions produced from diesel combustion and consist of nitric oxide (NO) and nitrogen dioxide (NO2). The nitrogen oxides from combustions are mainly air pollution generated by fuel combustion from stationary and mobile sources in the atmosphere. NOx emission can cause a series of health and problems such as eye and throat irritation and headache and environment issues such as toxic chemical smog and acid rain [1]. The post combustion technologies, selective catalytic reduction (SCR) has become dominant in controlling NOx emission from industries i.e., utility boilers and industrial furnace stacks [2,3]. There are many improvements aimed to reducing the SCR systems cost have been achieved, due to the space requirements and operating cost are still high cost [4]. The generation of ammonia emissions and the fouling of equipment with ammonium sulphate
