  • Comparative investigation of coal- and oil-fired boilers

    Jun 01, 2020 · In this study, VOC emission factors, O 3 and SOA formation potentials were estimated for two types of industrial boilers: coal-fired boilers (n = 3) and oil-fired boilers (n = 3). Results showed that ∑VOCs concentrations were more than nine times higher for oil-fired boilers compared to those for coal-fired boilers.Learn More

  • Lowering Nitrogen Oxide Emissions in a Coal-Powered 1000

    According to new environmental standards in China, the emission of nitrogen oxide (NO x) pollutants from boilers fueled by burning coal must be below 50 milligrams (mg) per standard or normal cubic meters (Nm 3) with a reference oxygen (O 2) content of 6%. Therefore, a new operation mode for reducing NO x emissions should be proposed. Most of Learn More
