“…Moreover, higher concentration of CO indicates preferential condition for NO x reduction by the reburning process. Hrycko and co-workers noticed that NO x emissions were approximately 40% higher (or more) from automatic coal-fired boilers than from traditional manually operated boilers . The fuel-NO mechanism is the main source of NO x emissions from solid fuel-fired boilers.…”

Nevertheless, the NO formation from volatiles constitutes most of the fuel-NO, while char-N oxidation is a minor source of NO x emission.…”

The emission of gaseous pollutants and particulates from domestic heating sources, DHS, can be especially troublesome in winter when the smog effect is enhanced. One of the possible ways to solve this problem is the use of fuel that emits significantly lower gaseous pollutants and particulates compared to hard coal. A major feature of this solution is the possibility of its immediate effect compared with other solutions that need more time to move toward a system change. This paper presents the findings from a laboratory and a full-scale operational pilot investigation into a smokeless fuel application (charcoal known as “Błękitny Węgiel”, BW) that is used for residential heating. Pilot experiments in users’ homes were carried out using 34 heating devices. A significant decrease of gaseous pollutants [NO x , SO2, total organic carbon, PAHs, and B(a)P] and particulate emissions from the heating devices was obtained when BW was applied, and this was even the case for boilers with outdated constructions.

“…The fluidized bed gasification, particularly with bubbling fluidized beds and circulating fluidized beds, is the most widely adopted method. , In terms of the cocombustion technology, the biogas is injected into the coal-fired boiler furnace, offering advantages such as accommodating a wide range of fuel types and preventing slag formation and corrosion within the furnace . Research indicates that cocombustion of biogas and coal influences the characteristics of ignition and combustion . Simultaneously, coal combustion enhances the stability of biogas combustion, fostering an interactive relationship with the furnace.…”

To further explore cocombustion technology with biogas and coal, a series of numerical simulations have been carried out to analyze the effects of the cocombustion ratio ξ, height of biogas nozzle H GN , and tilt angle of burner θ BN on combustion characteristics in a 300 MW four-corner tangential boiler furnace. Three types of biogas are gasified from straw, sawdust, and raw wood when air serves as the gasification agent. The velocity field, temperature field, and NO emissions have been comprehensively analyzed when the values of ξ, H GN , and θ BN range, respectively, from 0.02 to 0.12, from 17.3 to 20.3 m, and from −15°to +15°. Results showed that the NO concentration at the furnace outlet monotonously decreased with ξ. The injection of biogas reduces both the peak temperature of the entire boiler furnace and the NO concentration at the furnace outlet. The NO emission concentration decreases with the increased ξ value for all types of biogases. The cocombustion with sawdust biogas indicates the least NO emission at a fixed cocombustion ratio. Furthermore, reducing the furnace height at H GN = 17.3 m or titling down the burner at θ BN = −15°contributed to a greater NO concentration at the furnace outlet.
