80T Chain Boiler Heat Supply Company PNCR Polymer De-NOx Equipment

The heating company's 80T chain boiler utilizes PNCR high polymer denitrification equipment, which effectively reduces nitrogen oxide emissions. It boasts advantages such as high efficiency, economy, and ease of maintenance. The following is a detailed analysis:

Part 1: Overview of PNCR High Molecular Nitrogen Oxide Removal Technology

PNCR polymeric denitration technology is an in-furnace denitration process that utilizes an intelligent automatic conveying system for powdery gas phase to inject solid polymeric reductant through a spray gun into the boiler combustion chamber. It sublimates into NH₃ in the appropriate reaction zone (usually 700℃-900℃) and undergoes a reduction reaction with NOx, achieving ultra-low emission standards. This technology boasts a wide temperature range for reactions (450℃-1000℃), fast reaction speed, high efficiency, and is unaffected by dust and SOx.

Section 2: 80T Chain Boiler PNCR Polymer Denitrification Equipment Composition

1. Storage System: Utilizes an external modular drug storage, made of stainless steel for easy assembly and disassembly, designed for storing high molecular weight denitrification agents.

2. Shangyu SystemUtilizing vacuum-assisted suction method to ensure complete medication particles, reducing the risk of breakage and pipeline blockage.

3. Intelligent Precise Medication Supply SystemAchieve precise drug dosage supply, stable batching, and prevent medication waste.

4. Conveying SystemConstructed with high-quality stainless steel, both inside and out polished to a mirror finish, paired with an independent chuck connection, ensuring smooth flow of medication, preventing any clogging or damage.

5. Air Duct SystemTo provide a stable airflow for the jet system, ensuring the polymer denitrification agent is evenly sprayed into the boiler.

6. Injection SystemThe nozzle is a critical component for ensuring the stable operation of the denitrification system. Typically, a 310S nozzle with a high temperature resistance of up to 1200℃ is chosen, equipped with an internal temperature sensor to real-time monitor the nozzle temperature, thereby adjusting the spray points accordingly.

7. Control SystemConnect to the online monitoring equipment to monitor NOx emission signals. Based on the signals from the boiler induced draft fan and furnace thermocouples, determine the boiler's operating status, and use this to control the dosing frequency and amount for each piece of equipment.

Section 3: Advantages of 80T Chain Boiler PNCR High Molecular Nitrogen Oxide Removal Equipment

1. EfficiencyThe PNCR High Polymer Denitrification Equipment utilizes high polymer chemical adsorption technology to generate a large number of free radicals under high pressure for the removal of NOx from exhaust gases. It boasts a high denitrification efficiency, typically reaching 80%-95%.

2. EconomicalEquipment investment and operating costs are relatively low, and the denitrification agent is in the form of solid particles, easy to store, and highly safe. Additionally, this technology does not require a separate reactor, reducing the equipment footprint and shortening construction time, further cutting costs.

3. Ease of maintenanceThe PNCR denitrification equipment does not require chemical reagents. By optimizing the particle structure and size, it can achieve long-term stable operation of the equipment, significantly reducing maintenance costs.

4. Eco-friendlinessThe entire restoration process takes place inside the boiler, ensuring no secondary pollution and compliance with environmental protection standards.
