Product Description

Product Introduction
            Chain grate bar : is a key component for combustion equipment (such as boilers, incinerators, etc.), mainly used for solid fuels (such as coal, biomass, waste, etc.) transport, distribution and combustion control. Its core feature is to achieve the active movement of the grate through mechanical or hydraulic drive devices, thereby optimizing the combustion efficiency, stabilizing the heat load, and reducing pollutant emissions.
Chain grate bar  technology significantly improves the reliability and environmental performance of solid fuel combustion equipment through precise mechanical control and aerodynamic design, and is an important solution in the field of modern energy and environmental protection.

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:
1. Basic issues
Q1: What is an active grate? What is the difference between it and a regular grate?
A: Active grate is a grate system that achieves automatic movement through motor, hydraulic or mechanical drive, and can actively push and flip fuel to improve combustion efficiency; However, ordinary grates (such as fixed grates) lack driving devices and have lower combustion efficiency.

Q2: Which boilers are suitable for active grate?
A: Mainly used for equipment that requires continuous combustion and efficient slag discharge, such as garbage incinerators, biomass boilers, and coal-fired chain furnaces.

2. Structure and operation
Q3: What are the key components of an active grate?
A: Mainly includes:
-Stove plate (made of high-temperature resistant alloy material)
-Drive device (motor, hydraulic cylinder or linkage mechanism)
-Wind chamber system (segmented air supply control)
-Supporting frame (heat-resistant steel structure)

Q4: What are the ways of active grate movement?
A: Common forms of exercise include:
-Reciprocating (alternating movement of grate plates)
-Chain type (grate plate moves slowly with the chain)
-Tilt reverse thrust type (used for garbage incineration, with fuel and grate moving in opposite directions)

Q5: How to adjust the operating speed of the active grate?
A: By adjusting the speed through a frequency converter (motor-driven) or hydraulic system, it is usually optimized based on fuel type, combustion load, and slag discharge requirements.
