What causes abnormal noise during grate operation?

Noise may result from scale detachment, worn sprocket teeth, or lack of lubrication in guide rails. Solutions include tightening bolts, replacing worn sprockets, and replenishing lubricating oil.

How to extend the service life of the scale grate?

Extend life through regular maintenance (cleaning dust/coke), standardized operation (avoiding overload), using high-quality wear-resistant materials, monitoring combustion status, and contacting professional engineering teams for support.

AI-Powered supplier vetting

SummaryShandong Jiaguang International Trade Co., Ltd. is identified as a Chinese manufacturer/factory specializing in boiler accessories, with stated manufacturing experience, a modern production base, and a senior technical team. The supplier reports ISO9001, CE, and SGS origin certifications, and offers 3D design, ODM, OEM, and multiple customization options. However, the evidence also shows no valid manufacturing-capacity contract with related subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Quality procedures exist, but approved-supplier records, corrective/preventive-action records, and complaint-handling records are incomplete. Financial credibility cannot be established from the provided data because the reported financial figures are zero and no further verification is available. Customer cases are not specifically documented.

Supplier typeThe supplier is identified as a manufacturer/factory and a high-tech enterprise specializing in the R&D, production, sales, and service of boiler accessories. Its company type is also recorded as combined, with operations in manufacturing and industrial equipment-related sectors.

CertificationsThe company states that it has passed ISO9001 international quality system certification, CE certification, and SGS origin certification. Quality assurance is also reported in its quality-control processes, although several supporting quality records are incomplete.

R&D capabilityThe supplier is described as a professional technical supplier with R&D capability, 3D software design services, ODM services, and a senior technical team. However, it reported no new products in the past year and has no available SDK, so evidence of recent product innovation is limited.

Customization capabilityThe supplier provides 3D software design services and supports customization from designs, samples, full customization, minor customization, and flexible customization. It also reports ODM and OEM capabilities, directly supporting a broad customization offering.

Product Q&A

Q:What causes jamming or freezing of the scale grate?

Causes include deformation or wear of grate plates, foreign object blockage, insufficient lubrication, or installation deviation. Solutions involve cleaning foreign objects, replacing deformed plates, strengthening lubrication, and correcting installation levels.

Q:How to solve serious coal leakage in the scale grate?

Leakage is often caused by excessive gaps between grate plates, poor coal quality (too fine or dry), or poor scale closure. Solutions include adjusting or replacing grate plate gaps, controlling coal particle size (10-25mm), and checking the closure mechanism.

Q:Why does the scale grate chain elongate or break?

Causes include long-term high-temperature fatigue, overload operation, and poor lubrication. Solutions involve replacing with high-temperature resistant alloy chains, controlling load, and regular lubrication with high-temperature grease.

Q:How to prevent grate burning or rapid oxidation?

Prevention requires using heat-resistant materials (not ordinary cast iron), ensuring uniform air distribution, and avoiding rapid cooling after shutdown. Slowly cool down the furnace to prevent cold air oxidation.

Q:What causes deviation or unilateral wear in the scale grate?

Causes include uneven chain tension, worn or offset guide rails, and non-parallel drive shafts. Solutions involve adjusting chain tension, repairing or replacing guide rails, and correcting drive shaft parallelism.
