Suppressing pollutant emissions from boilers firing stone coal
- Univ. of Mining and Metallurgy, Ostrava (Czechoslovakia)
Industrial plants are often unaware that simple adjustment of the combustion process can significantly reduce the NO{sub x}, SO{sub 2}, and fly ash emissions. A systematic approach to the problem indicates that the character and adjustment of the combustion process not only can create favorable conditions for binding solid combustion residues and minimizing their amounts at the point of combustion, but can also modify their physical, chemical, and/or electrical properties to make them easier to trap in electrostatic precipitators. Similarly, gaseous pollutants such as SO{sub 2}, NO{sub x}, F, Cl{sub 2}, HCl, and HF, as well as heavy metals and simple hydrocarbons, can be bound more easily by aerodynamic interventions, which also allow further reductions of pollutant emissions by suitably dosed additions of limestone and dolomite. This work covered the measurement methods employed in the furnaces, mathematical three-dimensional modeling of the furnaces, and isothermal two-component modeling of the burners. In order to cover as many types of pollution-generating combustion equipment as possible and to define the fundamental measures needed to limit their contaminating effect to a bare minimum, the work was divided into four areas: stroke-fired boilers, fluid bed boilers, pulverized coal boilers, and flue gas cleaning.
