Sodium based dry desulfurization for Steel Plant

Service country: Indonesia
Capacity: 2*75t/h Alumina circulating fluidized bed boiler
Method: Adopted desulfurization by calcium injection in boiler and limestone- gypsum outside boiler (high temperature and high pressure boiler matching electric bag compound desulfurization system)
Technology requirements:
(1) The emission concentration of SO2 < 200mg/Nm3 (the guaranteed efficiency of desulfurization in furnace is 40%). The particulate emission concentration< 50mg/m3.
(2) Total desulfurization efficiency: ≥98.5%;
(3) Dust removal efficiency: ≥99%;
(4) System air leakage rate: ≤ 2%; (5) Mature management technology, low project investment, high cost performance, small area, easy operation and maintenance, low operating cost and long service life.
Cooperation Type: EP(Engineering&Procurement)
