Sodium bicarbonate desulfurization powder pneumatic conveying systems are widely used in flue gas treatment projects where dry sorbent injection is required. This solution handles sodium bicarbonate powder safely, continuously, and accurately from storage silos to injection lances. Our customized conveying systems are designed for power plants, waste incinerators, cement plants, glass furnaces, and industrial boilers that need efficient SO2 and acid gas removal.

With years of engineering experience, we provide complete sodium bicarbonate deSOx powder conveying solutions integrating silo storage, discharge devices, pneumatic conveying pipelines, injection equipment, control instrumentation, and compressors. Each system is tailored to the customer's site layout, conveying distance, material characteristics, and process requirements. We support both dilute phase and dense phase conveying modes to meet different capacity and energy-saving targets.

System design and customization: Our engineering team evaluates material bulk density, particle size, moisture content, and flowability before selecting the conveying method. Sodium bicarbonate powder is cohesive and slightly abrasive; therefore, the system design must avoid bridges, agglomeration, and unstable feed rates. We design hopper discharge aids, rotary valves, screw feeders, and mixing nozzles to ensure uniform injection into the duct. The conveying gas is usually compressed air or nitrogen, and the pipeline route is optimized to minimize bends and pressure drop.

Core components: We offer a full range of high-quality equipment, including storage silos, bin vent filters, level indicators, safety valves, discharge stations, rotary feeder valves, blow pots, air compressors, moisture separators, pressure transmitters, flow control valves, static mixers, and injection lances. All parts in contact with sodium bicarbonate are manufactured with wear-resistant materials and sealing solutions to prevent dust leakage. A PLC-based control system automatically sequences conveying cycles, monitors pressure and flow, and alerts operators in case of abnormal conditions.

Pneumatic conveying process: Sodium bicarbonate powder is delivered by tanker or bulk bag to the storage silo. From the silo, the powder is discharged through a rotary valve or vibrating feeder into the conveying line. High-pressure air pushes or carries the powder through the pipeline to the injection point. At the injection lance, compressed air disperses the powder into the hot flue gas stream. The rapid thermal decomposition of sodium bicarbonate creates a large surface area for acid gas neutralization, maximizing desulfurization efficiency.

Advantages: This conveying solution offers stable feeding, closed operation, low maintenance, flexible layout, and high automation. Compared with belt conveyors or manual feeding, pneumatic conveying avoids dust pollution and material loss. The system can be arranged horizontally, vertically, or with multiple branch lines. Our customized equipment ensures high conveying accuracy and reliable non-stop operation for continuous desulfurization processes.

Applications: The system is suitable for municipal solid waste incineration, biomass power generation, coal-fired boilers, industrial waste gas treatment, steel sintering, cement kilns, glass melting furnaces, and chemical plants. It is also used for emergency sorbent injection and semi-dry flue gas cleaning systems. By selecting sodium bicarbonate as an alternative to lime or hydrated lime, users can reduce waste residue and improve acid gas removal performance.
