High Efficiency Pulverized Coal Boiler for Power Plant
Our high efficiency pulverized coal boiler for power plant delivers reliable steam generation while minimizing fuel consumption and emissions. Engineered for large‑scale utilities, the unit integrates advanced combustion technology, robust heat‑transfer surfaces, and smart control systems to meet the demanding operational cycles of modern power stations.
How It Works
Pulverized coal is atomized into a fine powder and injected into the furnace where a high‑velocity air stream creates a perfectly mixed flame. The intensified turbulence ensures complete combustion at lower excess‑air levels, raising the furnace temperature and boosting overall boiler efficiency. Heat from the flame is transferred through a cascade of water‑cooled tubes, producing superheated steam ready for turbine drive.
The integrated control panel continuously monitors key parameters—combustion temperature, oxygen content, and steam pressure—and automatically adjusts fuel feed and air flow to keep the system operating at its optimal point, even during load swings.
Technical Specifications
The following table outlines the typical specification range. All parameters are fully customizable to match project‑specific requirements.

| Net Boiler Efficiency | 38 – 44 | % |
| Design Pressure | 12 – 20 | MPa |
| Design Temperature | 540 – 580 | °C |
| Fuel Feed Rate | 30 – 150 | kg/s |
| Water‑side Superheat Surface | 45 – 70 | % of total tube area |
Competitive Advantages
- **Fuel‑Savings Engine:** Optimized pulverizing and low‑excess‑air combustion cut coal consumption by up to 6 % compared with conventional drum‑type units.
- **Reduced Emissions:** Integrated low‑NOx burners and flue‑gas recirculation keep SOx and NOx within the most stringent EU‑III/China III limits without after‑treatment.
- **Extended Life‑Cycle:** High‑strength alloy tubes and a corrosion‑resistant furnace lining provide a 30‑year design life with minimal tube‑sheet replacement.
- **Rapid Start‑up:** Advanced automation shortens warm‑up time to under 30 minutes, enabling flexible load management for intermittent renewable integration.
- **Modular Design:** Factory‑fabricated modules allow on‑site assembly within 60‑90 days, reducing construction risk and capital exposure.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a customized boiler?
We typically require a single unit as the MOQ because each boiler is engineered to the buyer’s specification. Larger projects can benefit from volume discounts on accessories and spare‑parts packages.
Can the design be adapted for lower or higher steam capacities?
Absolutely. Our engineering team can scale the furnace volume, turbine‑driven fans, and heat‑transfer surfaces to match capacities from 100 t/h up to 1 000 t/h while preserving the high‑efficiency combustion profile.
What is the typical lead time from order to delivery?
Standard projects ship within 15‑45 days after final design approval and receipt of the initial deposit. Complex configurations or special material requests may extend the timeline, which we communicate early in the quotation phase.
What warranty and after‑sales support are provided?
All units come with a 24‑month comprehensive warranty covering material defects and workmanship. Our global service network offers on‑site commissioning, routine maintenance contracts, and spare‑part logistics to keep the boiler operating at peak performance.
