  • 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.Learn More

  • MSAPR Part 1 – Boilers and Heaters

    Mar 30, 2020 · MSAPR establishes a process for registering, monitoring, testing and reporting of oxides of nitrogen (NOX) emissions and provides NOX emission intensity limits (g NOX/GJ). These limits are phased in over time for pre-existing boilers and heaters based on the determined classification and the timing of trigger events or major modifications Learn More

If a Generation Unit has multiple stacks, each serving one or a discrete number of boilers, then the size range and emission limit would apply to each stack separately.Learn More

  • Cast-Iron Steam Boilers - Certified Commercial Property

    Cast-iron boilers are often found in residential applications and small commercial installations. These boilers are compact and function exclusively in low-pressure steam or hot-water applications. The physical size of a cast-iron steam boiler can be quite large, with the sections visible, since it has no casing. Cast-iron is basically steel.Learn More

  • Reducing emissions and improving boiler efficiency through

    Feb 14, 2019 · Variables which will promote CO and NOx reduction are choosing a larger boiler or adding more residual oxygen. Unfortunately, burner manufacturers are unable to do this and there are some downsides, such as associated investment and operational costs. Instead, burner manufacturers set out to find an optimal balance between CO and NOx formation.Learn More

  • 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 .Learn More
