Application of High-Specific-Surface-Area Calcium Hydroxide in Flue-Gas Desulfurization in the Heating Industry
Urban district heating systems and industrial heating boilers are typically operated seasonally: running at full load during the winter months and idling at low load during the rest of the year. This results in frequent start–stop cycles, significant fluctuations in flue‑gas sulfur content, and pronounced intermittent emissions. Moreover, small and medium‑sized heating boilers are often installed in confined spaces, making it impractical to deploy large-scale wet‑scrubbing desulfurization units. High‑specific‑surface calcium hydroxide, when paired with compact dry‑scrubbing systems, represents an economical and practical desulfurization agent for the heating sector.

Application of High-Specific-Surface-Area Calcium Hydroxide in Flue-Gas Desulfurization in the Glass and Ceramic Industry
The glass and ceramics industries rely on high‑temperature kiln firing to melt raw materials. Fuel combustion and the thermal decomposition of these materials generate sulfur‑containing flue gases that are both hot and highly viscous, while also containing silicate dust. This dust readily adheres to the surface of desulfurization agents, deactivating their catalytic performance. As a result, conventional agents have short service lives and require frequent replacement. High‑specific‑surface‑area calcium hydroxide, with its well‑developed porosity and strong anti‑adhesion properties, is ideally suited to the unique flue‑gas conditions found in glass and ceramic kilns.

Efficient Purification, Contributing to Blue Skies: Innovative Application of Wanda Tech's High-Specific-Surface Calcium Hydroxide in Flue Gas Desulfurization
With the continuous tightening of national environmental policies and the advancement of the "Dual Carbon" goals, industrial flue gas treatment, particularly the reduction of sulfur dioxide (SO₂), has become a critical challenge for many energy-intensive industries. Among various desulfurization technologies, dry/semi-dry flue gas desulfurization (FGD) is widely used in sectors like steel, building materials, and waste incineration due to its simple process, no wastewater discharge, and relatively lower investment costs. The quality of calcium hydroxide (Ca(OH)₂), the core reagent in this technology, directly determines the final efficiency of the desulfurization system. Wanda Technology, deeply engaged in the field of environmental protection materials, produces high-specific-surface-area calcium hydroxide through dedicated R&D. This product is becoming a key force in promoting clean flue gas emissions due to its exceptional performance.
