The use of ceramic fiber module in the insulation layer of the exhaust gas incinerator mainly reflects its characteristics of high efficiency, light weight, high temperature resistance and easy construction. Here's how to use it:
1. Material selection and preparation
Ceramic fiber modules: Choose high-purity ceramic fiber modules that are suitable for high-temperature environments, usually these modules have good thermal insulation properties and chemical stability.
Supporting materials: such as ceramic fiber blankets (which may be used to tile or fill gaps), high-temperature curing agents (used to enhance the erosion resistance and extend the service life of fiber modules), U-nails or heat-resistant steel anchors (used to secure modules), etc.
2. The installation steps
Furnace preparation: Before installation, the furnace should be thoroughly cleaned to ensure that there is no debris and no corrosion, and the integrity and tightness of the furnace structure should be checked.
Measurement & Cutting: Accurately measure and cut the ceramic fiber modules according to the furnace size and design requirements to ensure a tight fit between the modules and reduce the thermal bridging effect.
Laying & Fixing:
Bottom laying: Ceramic fiber modules are usually laid from the bottom of the furnace chamber, either tiled or staggered to ensure that the joints between the modules are uniform and minimal.
Fix the module: Use U-nails or heat-resistant steel anchors to fix the module on the inner wall of the furnace to ensure that it is firmly fixed and avoid loosening or falling off at high temperatures. For the top or special parts, a special fixation method may be required, such as temporary fixation with a quick card fit bolt.
Filling gaps: In the gaps between modules, a layer of ceramic fiber blanket can be laid to fill them to improve the insulation effect.
Surface Treatment: Brush or spray a high-temperature curing agent on the surface of the ceramic fiber module to enhance its erosion resistance and extend its service life. Pay attention to the selection of a hardener that is compatible with the module material and ensure that the application is evenly applied.
3. Precautions
Installation sequence: Follow the principle of laying from the bottom of the furnace upwards and from both sides to the middle to ensure that the installation sequence is reasonable.
Safety protection: During the installation process, the operator should wear appropriate protective equipment, such as dust masks, protective glasses and protective clothing, to ensure the safety of the operation. At the same time, the ventilation of the workplace should be strengthened to reduce the accumulation of dust and harmful gases.
Temperature management: In the process of heating and cooling, the heating rate and cooling rate should be strictly controlled to avoid excessive thermal stress and damage to the aluminum silicate ceramic fiber module.
Regular inspection and maintenance: During use, the integrity and thermal insulation performance of the aluminum silicate ceramic fiber module should be checked regularly, and the damaged module should be repaired or replaced in time. At the same time, keep the atmosphere in the furnace clean and stable to avoid the erosion of harmful gases.
Through the above steps and precautions, the aluminum silicate ceramic fiber module can effectively play a role in the insulation layer of the exhaust gas incinerator and improve the thermal insulation performance and service life of the furnace body.
