High Pressure Water Tube Coal Fired Boiler – Engineered for Heavy‑Duty Industrial Power
Why This Boiler Stands Apart
In large‑scale power generation, process heating, and district heating networks, reliability is non‑negotiable. Our high pressure water tube coal fired boiler delivers continuous steam output at pressures up to 16 MPa while maintaining a compact footprint. Designed for plants that demand 30–150 t/h steam capacity, the unit integrates advanced water‑tube technology with proven coal combustion systems, giving you the efficiency of modern engineering and the fuel flexibility of traditional sources.
Competitive Edge – What Sets Our Boiler Apart
- Optimized water‑tube layout reduces fouling and extends tube life beyond 10 years under continuous operation.
- Low‑NOx combustion chamber meets stringent environmental regulations without additional after‑treatment.
- Modular design enables rapid onsite assembly—typical erection time 4–6 weeks.
- Full compatibility with ISO 9001, ISO 14001, and ASME‑Section VIII pressure vessel standards.
- Customizable feed‑water treatment packages and control panels to match existing plant automation.
Real‑World Applications
The versatility of a high pressure water tube coal fired boiler makes it a go‑to solution across multiple sectors:
- Thermal Power Plants: Generates high‑grade steam for turbine drives, supporting baseload and peak‑load operations.
- Chemical & Petrochemical: Provides process steam for distillation, reforming, and catalytic cracking.
- District Heating Networks: Supplies pressurized hot water to municipal heating grids, reducing reliance on imported fuels.
- Paper & Pulp Mills: Meets the high steam demand for drying and pulping processes with stable pressure control.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑built boiler?
We produce each unit to order. The MOQ is a single fully configured boiler, which includes the furnace, water‑tube bank, control system, and optional auxiliary equipment. This approach keeps inventory costs low for our customers.
Can the design be adapted for low‑sulfur coal or alternative solid fuels?
Yes. Our combustion chamber can be re‑engineered to handle low‑sulfur, high‑ash, or blended solid fuels. Modifications include adjusted grate spacing, enhanced slag‑removal systems, and optional flue‑gas desulfurization interfaces.
What is the typical lead time from order confirmation to shipment?
Standard lead time ranges from 15 to 45 days, depending on the selected configuration and any special material certifications required. Expedited production is available upon request.
What warranty and after‑sales support are provided?
All boilers are covered by a 24‑month parts warranty and a 12‑month on‑site service guarantee. Our technical support team is reachable 24 hours a day, 7 days a week, and we maintain a global spare‑parts network to minimise downtime.
