Coal desulfurizer for desulfurization and card increase

Coal desulfurizer is a chemical agent that converts sulfur elements in coal into harmless substances through chemical reactions, thereby reducing pollutant emissions. The main technical principles include:

Coal blending and sulfur fixation technology: Mix the sulfur fixation agent evenly with coal and enter the boiler for combustion. The oxides in sulfur fixing agents (such as Al ₂ O3, SiO ₂, MgO, Fe ₂ O3, TiO ₂, CaO, etc.) form silicate solid solutions with sulfur at high temperatures, preventing the re decomposition of sulfur products and improving sulfur fixing efficiency

Pre combustion desulfurization technology: including physical desulfurization (gravity coal selection can reduce sulfur by 49.7%) and chemical methods (molten caustic alkali leaching, chemical oxidation, and solvent extraction)

Combustion desulfurization technology: such as coal based sulfur fixation and fluidized bed combustion desulfurization technology

Post combustion desulfurization technology: covering wet (limestone gypsum method), dry and semi dry processes

New desulfurizers such as hydroxylated iron oxide desulfurizers have a 40% increase in sulfur capacity compared to traditional products, and their active sites are three times that of ordinary desulfurizers
