NITROGEN OXIDES FORMATION in combustion processes

Mar 16, 2012 · Recent regulations have required reductions in emissions of nitrogen oxides (NO x) from electric utility boilers. To comply with these regulatory requirements, it is increasingly important to implement state-of-the-art NO x control technologies on coal-fired utility boilers. This paper reviews NO x control options for these boilers. It discusses the established commercial primary and secondary …

The main sources of nitrogen oxides in boiler flue gas are

Mar 30, 2021 · The main sources of nitrogen oxides in boiler flue gas are mainly composed of two parts: Mar 30, 2021. The main sources of nitrogen oxides in boiler flue gas are mainly composed of two parts: 1. The combustion of nitrogen-containing compounds in the coal is produced; 2. The combustion temperature of the boiler is too high, causing the N2 in the air to be oxidized to NOX. 1 The analysis of Zhongyuan Coal Industry does not test the nitrogen content, but according to the actual production …

1.2 Anthracite Coal Combustion

Feb 01, 2016 · When brown high-moisture coals are burnt in the medium power boilers, generally fuel nitrogen oxides are produced. It is possible to reduce their production by two ways: lowering the temperature in the core of the torch or decreasing the excess-air factor in the boiler furnace.

Nitrogen Oxides - an overview | ScienceDirect Topics

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.

of nitrogen in the fuel.16 In pulverized coal combustion in a utility boiler, fuel NO x may typically contribute up to 80% of the NO x emissions.14 Formation of fuel NO x depends on the nitrogen content in the fuel and the amount of oxygen available to react with the nitrogen during coal devolatilization in the early stages of com-bustion. Accordingly, fuel NO
