25 Ton Pulverized Coal Boiler – High‑Performance Steam Generator
Our 25 ton pulverized coal boiler is engineered for continuous, high‑capacity steam production in power‑generation, petrochemical, and large‑scale industrial facilities. Whether you are updating an existing plant or building a new cogeneration unit, the 25 ton pulverized coal boiler price list provides transparent cost benchmarks for a turnkey solution that meets stringent efficiency and emission standards. Designed for a nominal output of 25 tons of steam per hour, the system integrates advanced combustion control, low‑NOx burners, and modular construction for rapid on‑site assembly.
How It Works – Pulverized Coal Combustion Cycle
Pulverized coal is ground to a fine powder (30–80 µm) and injected into the furnace where it mixes with preheated secondary air. The high surface‑to‑volume ratio ensures rapid ignition and a stable flame front, delivering a uniform heat flux across the boiler tubes. Precise air‑fuel ratio control, managed by a digital PLC system, maximizes combustion efficiency (typically > 90 %) while keeping nitrogen oxide emissions below regulatory limits. The generated heat transfers to the water‑wall tubes, producing saturated steam that can be superheated on demand.

Competitive Advantages
- Modular Design: Factory‑built sub‑assemblies allow installation in confined spaces and reduce on‑site construction time by up to 40 %.
- Energy‑Saving Controls: Adaptive load‑following algorithms automatically adjust air‑fuel ratios, minimizing coal waste and fuel cost.
- Compliance Ready: The boiler meets ISO 9001, ISO 14001, and ASME Section III standards; documentation for CE and IECEx is available on request.
- Robust After‑Sales Support: 24 × 7 remote monitoring, spare‑parts inventory in major ports, and on‑site commissioning assistance.
- Transparent Pricing: Our 25 ton pulverized coal boiler price list is published per unit, with clear cost breakdowns for optional accessories, making budgeting straightforward for EPC contractors.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a 25 ton pulverized coal boiler?
Our standard MOQ is one complete boiler package, which includes the furnace, water‑wall, burners, and control panel. Smaller pilot‑scale units can be fabricated on request, but lead times will increase.
How does the 25 ton pulverized coal boiler price list reflect optional upgrades?
The base price covers the core boiler and standard controls. Options such as low‑NOx burners, alloy‑enhanced tubes, or DCS integration are itemized separately in the price list, allowing you to select only the features that align with your project budget.
What is the typical lead time from order confirmation to shipment?
Standard units are shipped within 15‑45 days, depending on the selected options and current production schedule. Custom‑engineered variants may require up to 90 days.
What warranty and after‑sale services are included?
All boilers carry a 12‑month warranty covering material defects and workmanship. Extended warranty packages (up to 36 months) and a full maintenance contract can be added at the time of purchase.
