Design of a partially premixed burner for biogas-fired

Aug 11, 2020 · Therefore, the biogas-fired wall-mounted boiler is suitable for the biogas containing 40–60% of the CH 4 when the excess air coefficient is 1.7. As can be seen from Figure 8, the emission of NO x also increased with the increase of CH 4 because the generation of NO x is closely related to the combustion temperature whose rise can promote NO x .

Specific NOx briefing

SNCR on lignite boilers SNCR is a standalone NOx control technique and is combined with other primary techniques such as combustion controls. Conceptually, it is quite a simple technology, where a reduction agent (urea/ammonia) is injected directly in the boiler chamber and reduce NOx formation trough a chemical reaction.

Before the boiler is atomized or injected into the boiler, it is atomized by the heat in the furnace. Sprayed into the furnace temperature range of 800 ℃ ~ 1100 ℃, the reducing agent quickly thermally decomposed into NH3 and other by-products, and then NHCR and NOx in the flue gas undergo SNCR reaction to generate N2.
