Product Certification
Product packaging 
1. Principles of Packaging Design
Protection Shock proof and buffering: precision accessories (such as instruments and valves) need to be filled with foam, bubble film, pearl cotton, etc. to avoid damage caused by transportation shock.
Moisture and rust prevention: Metal components (such as pipelines and flanges) need to be coated with rust prevention oil and packaged with moisture-proof film or vacuum. Desiccant should be added during sea transportation.
Anti pressure and anti drop: Heavy accessories (such as burners and drums) are reinforced with wooden boxes or steel frames, indicating the load-bearing direction and stacking layer limits.

2. Standardization and identification
Comply with international transportation standards (such as ISO, ISTA), indicate weight, size, lifting point, "fragile", "moisture-proof", "upward" and other markings.
Dangerous accessories (such as fuel injectors) must be labeled with UN certification and comply with the International Maritime Dangerous Goods Code (IMDG).

3. Container division strategy
Small items (bolts, washers) should be packaged in a uniform size box to avoid loose parts; Large items (heat exchangers) are individually customized in wooden boxes with supporting frames inside.

Product transportation
Transportation mode selection
1. Shipping by sea
Suitable for bulk accessories such as steel plates and large pipelines, pay attention to container size (20GP/40HQ) and load balance.Sea freight requires anti salt spray treatment, with moisture-proof agents placed inside the container and sealed.

2. Land transportation
Heavy accessories (over 3 tons) require flatbed trucks or low chassis vehicles, and routes should be planned in advance to avoid height/weight restrictions.Cross border transportation inspection of various countries' requirements for wooden packaging (such as ISPM15 fumigation certificate).

3. Air freight
Urgent small items (electronic controllers) should be prioritized for air transportation, and the weight of each item should be controlled (usually<100kg) to reduce packaging weight and save costs.

FAQ:
Frequently Asked Questions about Boiler Accessories Chain (Chain Stove) (Q&A)

Q1: Why does the chain grate deviate during operation? How to adjust?
A1:  
reason:
The tension of the chain is uneven (loose on one side and tight on the other).
The sprocket is worn or misaligned (left or right offset).
The grate plate is damaged or stuck with foreign objects, resulting in uneven force distribution.
resolvent:
Adjust the tensioning device to ensure that the tension of the chains on both sides is consistent.
Check the wear of the sprocket and replace or correct it if necessary.
Clean up the accumulated dust or foreign objects on the grate, and replace the damaged grate pieces.

Q2: What should I do if the chain grate wears out too quickly?
A2:  
Possible reasons:
Fuel has high ash content and strong abrasion resistance (such as inferior coal or high ash biomass).
The chain material does not meet the standard (ordinary carbon steel is not wear-resistant).
The grate runs too fast, exacerbating friction.
Solution:
Choose wear-resistant materials (such as ZG40Cr high chromium cast iron or surface carburizing treated chains).
Reduce the operating speed of the grate and minimize wear and tear.
Regularly clean the ash residue to prevent hard particles from getting stuck.

Q3: What is the reason for the chain grate getting stuck (not moving)? How to deal with it?
A3:  
Common reasons:
Large pieces of coal slag or foreign objects stuck on the grate plate.
The chain is too loose or too tight, causing gear jumping or jamming.
Drive device malfunction (such as damaged gearbox, motor overload).
Handling method:
Emergency stop, manually reverse the grate, and clear any blockages.
Adjust the tension of the chain to the appropriate range.
Check if the drive system (motor, reducer, bearings) is functioning properly.

Q4: How to solve the serious coal leakage in the chain grate?
A4:  
Possible reasons:
The gap between the grate plates is too large (worn or deformed).
Fuel particles that are too small (such as crushed coal or powdery biomass).
The sealing performance of the scale grate is poor.
Improvement measures:
Replace worn grate plates and adjust the gap (usually 1-3mm).
Optimize fuel particle size (recommended 10-50mm).
Choose a scale grate with better sealing or install a leak proof device.

Q5: What should I do if there is a loud noise during the operation of the chain grate?
A5:  
Noise source:
Poor meshing between the chain and sprocket (wear or insufficient lubrication).
The grate plate is loose and produces abnormal noise due to collision.
Bearing or gearbox malfunction.
resolvent:
Lubricate the chain (using high-temperature resistant grease).
Tighten or replace loose grate plates.
Check the bearings and gearbox, and replace them if necessary.
