Product Overview
Our dumping grate stoker coal boiler wholesale is engineered for heavy‑duty industrial heating applications where reliability, fuel flexibility, and low operating cost are non‑negotiable. The unit combines a robust dumping grate mechanism with a high‑efficiency stoker, delivering stable combustion across a wide range of coal qualities. Designed for easy integration into existing plant layouts, the boiler is supplied in bulk to distributors, OEMs, and large‑scale power‑generation projects seeking a proven, low‑maintenance solution.
Technical Specifications
| Parameter | Typical Range | Units |
|---|---|---|
| Steam Output | 5 – 150 | t/h |
| Rated Boiler Pressure | 0.6 – 2.5 | MPa |
| Thermal Efficiency | 85 % ± 2 % | – |
| Fuel Feed Rate | 1 – 25 | t/h |
| Maximum Coal Size | 35 – 75 | mm |
| Operating Temperature | 300 – 520 | °C |
All figures are typical values; each order can be tailored to meet specific pressure, capacity, or fuel‑quality requirements. The modular design allows for quick scaling—add or remove stoker modules without major re‑engineering, a decisive advantage for projects with phased expansion plans.
Application Scenarios
The dumping grate stoker configuration excels in environments where coal quality fluctuates or where ash handling must be automated. Typical deployments include:
- Thermal power plants (up to 150 t/h steam) requiring continuous, low‑maintenance operation.
- Industrial process heating for cement, steel, and chemical facilities where high‑temperature steam is a process driver.
- District heating networks in regions with abundant low‑grade coal reserves.
- Remote mining camps where fuel logistics demand a robust, self‑cleaning combustion system.
Because the grate automatically dumps ash at preset intervals, manual ash removal is eliminated, reducing labor costs and downtime. The stoker’s precise fuel metering maintains stable flame conditions, which translates into consistent steam output—critical for process continuity.
Competitive Advantages
When sourcing dumping grate stoker coal boiler wholesale, buyers look for three decisive factors: operational reliability, total cost of ownership, and compliance with international safety standards. Our boiler delivers on all three:
- Proven durability: Heavy‑gauge steel frame and wear‑resistant cast iron grate plates give a service life of 20 + years under continuous operation.
- Low O&M expense: Automatic ash discharge and a self‑cleaning stoker reduce routine maintenance visits by up to 40 % compared with conventional fire‑tube boilers.
- Flexibility: The system accepts coal with moisture content up to 30 % and particle size up to 75 mm, minimizing pre‑processing costs.
- Regulatory compliance: Designed to meet EN 12952, ISO 9001, and relevant EPA emission guidelines; certification documents are provided with every shipment.
FAQ
What is the minimum order quantity for wholesale purchases?
We accept orders as low as a single unit for pilot installations, but bulk discounts start at 5 units. Custom pricing tiers are available for larger consignments.
Can the boiler be adapted for alternative solid fuels?
Yes. The stoker and grate geometry can be re‑engineered for biomass pellets, petcoke, or a coal‑biomass blend. Engineering changes are handled by our OEM team at no extra tooling cost for orders above 10 units.
What are the typical lead times?
Standard models ship within 15–30 days after order confirmation. Fully customized configurations require 30–45 days, depending on the complexity of the modifications.
Is there a warranty or after‑sales support?
All units come with a 24‑month comprehensive warranty covering manufacturing defects and on‑site commissioning assistance. Extended service contracts are available for up to five years.
