Product Description Product Introduction Fixed grate is a non movable grate structure in boiler combustion systems, mainly used in layered combustion boilers (such as hand fired furnaces, chain furnaces, etc.). Its core function is to:-Carrying fuel (coal, biomass, etc.) and providing air channels required for combustion.-Stable combustion ensures that the fuel is fully burned on the grate, reducing coal leakage losses.-Adapt to low volatile fuels (such as anthracite, coke, etc.) Product parametersproduct name Fixed gratematerialHeat-resistant Steel,Cast Iron,Cast Steel,Mild steel,Carbon Steel,Alloy Steel, etc.Material standardsASME,SAE,NF EN,DIN EN,ISO,BS EN,etcportQingdao Port, Tianjin Port, Guangdong Port.delivery time7~15 dayscountry of originShandong, ChinaSpecification drawing softwarePDF, Auto CAD,Solidworks,JPG, ProE,etc.Main production equipmentWax injection, CNc-machine-center, Lathe, Miling machine,Driling machine,Boring Lathe,Grinding Machine, Heattreatment Furnace.Heat treatment machineMesh-Belt-Furnace,Carburizing Quench Furnace,Chamer Furnace,etc.Surface TreatmentCold/Hot zn Plating,Blackening Treatment,Ni Plating,cr plating,Spraying Undercoat,Anti.Rust Paint,Surface Paint,Plastic Paint,Coated Anti-Rust Water,Anti-oil,etc.Surface Heat TreatmentMedium Frequence Quenching,High Frequence Quenching and Carburizing and Quenching,Oil Quenching,Waterquenching,Normalizing,Temper,Annealing,etc.Dimensional InspectionCalipers,Height Laugue,Micrometer Calipers,Inside Caliper Gauge,Angle and R Gauge,four coordinates measuringinstrument.productivity50000 tons /yearpackageWooden boxes, iron boxes, and othersCompany Profile Shandong Jiaguang International is a high-tech enterprise focusing on the research and development, production, sales and service of boiler parts.

Principles of Packaging DesignProtection 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 identificationComply 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 strategySmall 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 transportationTransportation mode selection1. Shipping by seaSuitable 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 transportationHeavy 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 freightUrgent 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 Fixed Boiler Grates (Q&A)Q1: Fixed grate is prone to blockage, how to clean it?A1: -Reason: Ash accumulation, high impurities in fuel, and small ventilation gap.-Solution:-Manual slag cleaning: After shutting down the furnace, use an iron hook to clean the gaps in the grate.-Adjust fuel: Use uniformly sized lump coal to reduce coal fragmentation.-Optimize ventilation: Check whether the air distribution in the air chamber is uniform to avoid local blockage.Q2: What should I do if the fixed grate burns, deforms or cracks?A2: -Reason: High temperature oxidation, material is not heat-resistant, and the combustion temperature is too high.-Solution:-Replace heat-resistant materials: Choose RQTSi4Mo or ZG40Cr25Ni20 heat-resistant cast iron/steel.-Control furnace temperature: avoid long-term overload operation.-Regular inspection: Observe the grate for cracks or deformation when shutting down the furnace.Q3: How to solve the serious coal leakage in the fixed grate?A3: -Reason: Excessive grate clearance, small fuel particles, and grate wear.-Solution:-Adjust grate plates: Replace grate plates with smaller gaps (such as narrow gaps in strip grate plates).-Use grate gaskets: Install heat-resistant gaskets under the grate to reduce coal leakage.-Optimize fuel: mix lump coal and crushed coal to improve combustion efficiency.Q4: What should be done if the ventilation of the fixed grate is poor and the combustion is insufficient?A4: -Reason: Thick ash layer, blocked air chamber, uneven air distribution.-Solution:-Strengthen dust cleaning: Regularly clean the accumulated dust in the air chamber below the grate.-Check the air door: Adjust the air volume once to ensure even air supply.-Manual slag turning: During the combustion process, adjust the fuel layer appropriately to improve breathability.Q5: How to extend the short service life of fixed grate?A5: -Reason: Poor material quality, high temperature oxidation, mechanical wear.-Solution:-Choose heat-resistant materials: RQTSi4Mo or high chromium cast iron is preferred.-Avoid rapid cooling and heating: cool naturally after shutdown, and do not splash water to cool down.-Regular maintenance: Check if the fixing bolts of the grate are loose to prevent deformation.Contact our professional engineering team promptly when encountering any questions!
