Product Description

Product Introduction
           AB active core grate is a key component commonly used in thermal equipment such as biomass boilers and waste incinerators. It is mainly used to support fuels (such as biomass pellets, waste, coal, etc.) and ensure ventilation, slag discharge, and optimized combustion efficiency during the combustion process. Its core features are modular design and movable grate plates, which can automatically adjust the combustion zone, improve combustion stability and thermal efficiency.

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:
AB Active Core Stove Frequently Asked Questions (Q&A)

Q1: What could be the possible reason for the AB active core grate getting stuck during operation? How to solve it?
A1: 
Possible reasons:
1. Excessive accumulation of ash and slag hinders the movement of the grate.
2. Drive system (hydraulic cylinder/motor) malfunction or insufficient lubrication.
3. The deformation or fracture of the grate plate causes mechanical jamming.
resolvent:
1. Stop the machine to clean the ash and check if the slag discharge system is functioning properly.
2. Check the hydraulic oil pressure or motor current, and replenish lubricating oil.
3. Replace damaged grate plates and adjust grate clearances.

Q2: How to extend the service life of grate plates that burn out too quickly?
A2:  
reason:
1. Fuel with high calorific value or local high temperature (such as garbage containing plastic).
2. Uneven air distribution leads to excessive combustion in some areas.
3. Material mismatch (such as biomass grate used for garbage incineration).
Improvement measures:
1. Choose high-temperature resistant materials (such as ZG40Cr30Ni20).
2. Optimize air distribution to ensure even combustion.
3. Regularly flip the fuel layer to avoid local overheating.

Q3: What should be done if there is severe air leakage in the grate, which affects combustion efficiency?
A3: 
reason:
1. Wear of grate plates or aging of sealing strips.
2. The installation gap is too large or deformed.
Solution:
1. Replace the sealing strip (made of silicone or ceramic fiber material).
2. Adjust the installation accuracy of grate plates and replace deformed parts if necessary.

Q4: How to troubleshoot the slow movement of the AB active core grate driven by hydraulic pressure?
A4:
Inspection steps:
1. Hydraulic system: Check whether the oil pressure meets the standard (such as ABH-50 requiring ≥ 10MPa) and whether the oil is contaminated.
2. Valves and pipelines: Check whether the solenoid valve is blocked and whether the oil pipe is leaking.
3. Load resistance: Confirm whether the grate is stuck by ash or foreign objects.

Q5: How to adjust the insufficient combustion of biomass fuel on the grate?
A5:  
Optimization method:
1. Increase the frequency of grate movement (e.g. from 5 times/minute to 8 times/minute).
2. Adjust the air distribution: The primary air (bottom) accounts for 60%~70%, and the secondary air (top) supplements oxygen.
3. Control fuel thickness: It is recommended to maintain a biomass layer thickness of 200-300mm.
