FAQ

Our company is committed to providing comprehensive boiler grate warranty and training services to ensure that customers have an in-depth understanding and support for our products.

By systematically mastering the core technical knowledge such as grate structural characteristics, ash accumulation diagnosis, ash cleaning maintenance, wear repair and parts replacement, trainees will be able to accurately deal with typical faults such as grate jamming and transmission failure, significantly improve the operating efficiency of the combustion system and extend the service life of the equipment.

Q What payment terms apply for orders over $50,000?

A 30% prepayment, 70% payment upon shipment. 5% discount available for bulk orders.
Q Do you offer CFD (Computational Fluid Dynamics) analysis to optimize furnace exhaust airflow?

A CFD analysis is available as an additional service to ensure uniform combustion and reduce hot spots.
Q What is the coverage of your global logistics network for the transportation of boiler equipment?

A We work with more than 50 certified carriers in 30 countries, ensuring coverage of major industrial areas (EU, North America, Southeast Asia) by air, sea and rail.
Q What packaging standards do you follow to ensure that boiler grates and components are not damaged during transportation?

A We use crates that meet ISO 2206 standards, using shock-absorbing materials, waterproof packaging, and reinforced wooden pallets. Hazardous parts are marked as per IATA/IMDG guidelines (where applicable).
Q What is the recommended maintenance interval for the moving grate bearings?

A
Lubricate every 400 operating hours and perform a full inspection every 2,000 hours for optimal performance.

Q Do your grates include thermal expansion compensation mechanisms?

A Yes, our designs feature sliding/flexible joints to accommodate thermal expansion of ±15mm at 500°C.
Q What is the lead time for manufacturing a replacement chain grate system?

A Standard sizes are in stock year-round and ready for shipment. Customized items take about 2-4 weeks.
Q What boiler grate material grades do you offer (e.g., heat-resistant cast iron, alloy steel)?

A We offer ASTM A48 Grade 35B cast iron, SA-515 Grade 70 carbon steel, and 310S stainless steel options.
Q Do your boiler grates comply with ASME Section I or ISO 5730 standards?

A
Yes, all grates comply with ASME Section I and ISO 5730 requirements, and certification is available upon request.
Q What is the maximum boiler capacity (in MW or tons/hour) that your cast iron/steel boiler grates can support?

A
Our standard grates support capacities up to 50 MW (or 150 tons/hour). Custom designs can expand this to 100 MW (300 tons/hour).
