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 Wind Hats

1. Question: What is the main function of the boiler air cap?
Answer: The main function of a hood is to:
-Uniform air distribution: evenly distribute high-pressure primary air to the bottom of the furnace to ensure that bed materials (such as quartz sand and coal ash) are fully fluidized.
-Prevent material leakage: Block the bed material from leaking into the air chamber through the air distribution board, while allowing air to pass through.
-Promote combustion: Enhance the mixing of fuel and oxygen through airflow disturbance to improve combustion efficiency.

2. Question: What are the reasons for the rapid wear of the hood? How to solve it?
Answer:
reason:-High hardness of bed materials (such as gangue coal, slag).
-The material is not wear-resistant (such as ordinary carbon steel used for high wear conditions).
-Excessive wind speed exacerbates airflow erosion.
solve:
 Replace with high chromium cast iron (KmTBCr26) or tungsten carbide wind cap welded.
 Adjust the wind pressure once (usually 0.8~1.5kPa) and reduce the wind speed.

3. Question: What should I do if the hood is blocked? How to clean?
Answer:
Reason for blockage:
-Ash residue adhesion (which is prone to occur in biomass boilers).
-The bed material particles are too fine (such as<0.1mm).

Cleaning method:
 Mechanical dredging: Clean the air vent with wire or steel needle.
 Compressed air blowback: Use a high-pressure air gun to blow during shutdown.
 Preventive measures: Use large-diameter air caps (diameter 8~10mm) or bell shaped structures instead.

4. Question: How to determine if the hood needs to be replaced?
Answer: If the following situations occur, replacement is required:
Wear and tear ≥ 30% thickness (e.g. original thickness of 15mm, remaining ≤ 10mm).
-Expansion or deformation of air vents (affecting airflow distribution).
-Fracture or severe erosion.
-Uneven air distribution (poor local fluidization).

5. Question: What should be noted when installing the hood?
Answer:-Horizontal calibration: All hood heights have an error of ≤± 2mm to ensure even air distribution.
-Tightening method: Welding or threaded connections should be firm to prevent loosening and detachment.
-Consistent spacing: usually 80-150mm, refer to boiler design drawings.
-Trial operation inspection: Conduct a no-load test to check if the wind pressure is balanced.
