Product Description

Product Introduction
             Link scraper (also known as chain scraper or grate scraper) is a key component in coal-fired boilers, biomass boilers, and slag removal systems, mainly used for fuel transportation (such as coal and biomass particles) and ash removal. They are usually installed on chain grate, reciprocating grate or scraper slag remover to ensure stable operation of the boiler.

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:
Boiler Link Scraper Frequently Asked Questions (Q&A)
Q1: What is the main function of the link scraper?
A1:  
-In a chain grate boiler, it is used to push coal or biomass fuel into the combustion zone.
-In the slag removal machine, it is used to scrape off ash and prevent accumulation from affecting the operation of the boiler.
-Ensure uniform distribution of fuel and improve combustion efficiency.

Q2: What are the common types of link scrapers?
A2:  
1. Classified by purpose:
-Stove scraper (used for fuel conveying)
-Slag scraper (used for ash removal)
-Biomass specific scraper (anti entanglement design)
2. Divided by structure:
-Single chain scraper (single-sided drive, simple structure)
-Double chain scraper (double-sided drive, more stable operation)
-Combination scraper (modular, easy to replace)
3. Classified by material:
-Carbon steel (Q235, economical type)
-Alloy steel (65Mn, wear-resistant)
-High chromium cast iron (Cr26, resistant to high temperature corrosion)

Q3: How to determine if the link scraper needs to be replaced?
A3:  
-Severe wear: The thickness of the scraper decreases by more than 30%, or the edges become thinner.
-Deformation/fracture: Scraper bending, cracking, affecting operation.
-Chain looseness: Chain jumping or falling off due to scraper wear.
-Decreased slag removal efficiency: An increase in ash accumulation may be due to wear or damage to the scraper.

Q4: What are the reasons for the rapid wear of the link scraper?
A4:  
-High fuel hardness (such as gangue coal, high ash coal).
-Material mismatch (ordinary carbon steel is used for high wear conditions).
-Poor lubrication leads to increased friction between the chain and scraper.
-Improper installation, such as inclined scraper or uneven force distribution.

Q5: How to extend the service life of the link scraper?
A5:  
-Choose suitable materials: alloy steel or high chromium cast iron for high wear environments.
-Regular lubrication: Keep the connection between the chain and scraper lubricated.
-Check fasteners: prevent bolt loosening from causing scraper displacement.
-Clean up debris: Avoid large pieces of coal slag or metal foreign objects getting stuck on the scraper.
