SZS series boiler is double drums, longitudinal arranged, "D" type chamber structure. Furnace is on right side and convection tube bundle is on the left, super heater is arranged at convection tube bundle. The body is fixed on the basement by middle and both end flexible supports and make the boiler to expand horizontally to sideways. Around furnace is membrane wall. Furnace and tube bundle is totally separated by the membrane wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, bundle area, and then from left front part enters spiral fin coil economizer and condenser, finally discharged to atmosphere through chimney.
CFBC technology is a new, efficient, and low-pollution clean coal method. This low-temperature combustion significantly reduces Nitrogen Oxide emissions and enables direct, high-efficiency desulfurization. Economically straightforward, CFBC lowers costs compared to other methods and accommodates various fuels, including low-calorific, low-quality coal. The resulting ash is reusable, eliminating secondary pollution. Moreover, CFBC supports wide load adjustments, operating down to about 30% of full load.
