ALTA technology was one of the first to prove that NO x emissions can be achieved below 0.15 lb/MMBtu on a coal-fired cyclone boiler when it was tested at AmarenUEs Sioux Unit 1
Utility boilers are far from isothermal, and adding biomass to a pulverized coal-fired boiler can significantly change the flame structure and characteristics. The addition of biomass has been shown to reduce NOx emissions in most commercial facilities, usually beyond the reductions expected because of a lower overall fuel-bound nitrogen content.

How is NOx Formed. In industrial boilers, NOx is primarily formed in two ways: thermal NOx; fuel NOx . Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the high temperatures in a flame. Thermal NOx makes up the majority of NOx formed during the combustion of gases and light oils.
PILOT-SCALE NOx AND SOx REMOVAL FROM BOILER EMISSION USING RADICAL INJECTION AND CHEMICAL HYBRID PROCESS and 70 ppm of NOx and 35 ppm of SOx for heavy oil, respectively. The radical gas generated from a 200 MW coal fired-boiler. The
bustion were not fully studied. In this paper, The NOx emission characteristics of volumetric combustion were studied thermodynamically based on a pulverized coal boiler. Moreover, the emission characteristics of another important pollutant, Sox, were also studied. Emission of Sox in coal-fired boiler is mainly determined by fuel types

Coal is an energy source with abundant reserves and the demand for coal-fired boilers is expected to continue in the coming years. Compared with gas or oil, on the other hand, coal produces higher CO2 emissions per unit of combustion energy and contains larger amounts of nitrogen, making environmental measures more important.
2 zThe role of coal in key figures Coal is a large contributor to EU energy supplywith a share of around 18 % of EU-27 total energy consumption; one third of power generation in the EU is based . on coal EU remains the third biggest consumer of coal worldwide despite rapid increases in coal
The effects of flue gas recirculation ratio, air preheating temperature, oxygen concentration, and fuel types on pollutants emission in the volumetric combustion system were investigated. According to the results, it was concluded the higher substitution ratio of biomass in a co-firing boiler, the lower emissions of NOx and SOx.
NOX emission reductions of about 5-25 percent and increases in boiler efficiency of 1 percent can be ex- pected with LEA. if fuel burnout does not change during the process. Residual-Oil-Fired Boilers As with coal-fired boilers, combustion modification NOX controls have been applied only to a limited number of oil- fired boilers.

High Functionality (Low SO2 Oxidation Catalyst) Flue gas generated when coal is burned contains SO2 (sulfur-dioxide) gas at a concentration of several hundred to a several thousand ppm (parts per million).
