What factors should be considered when purchasing circulating fluidized bed furnace lining refractory materials?

The circulating fluidized bed boiler has strong fuel adaptability, good combustion stability, a simple preparation system, and a long service life. Widely used in metallurgy, chemical industry, electric power, construction, and other fields. The normal operation of a circulating fluidized bed boiler is inseparable from the lining with reasonable structure, wear resistance, and fire resistance. How to choose circulating fluidized bed furnace lining refractory materials? What factors should be considered when purchasing circulating fluidized bed furnace lining refractory materials? RS refractory material manufacturer has material supply and construction experience in multiple circulating fluidized bed projects and can provide high-quality refractory castables and other refractory material products for circulating fluidized bed boilers.

First, determine the use environment and needs, and select suitable refractory materials.

Depending on the kiln type, combustion material, high temperature, acid and alkali properties, and other conditions, the applicable refractory materials are also different. Generally speaking, high-aluminum or corundum products can be selected for neutral environments, and magnesium products can be selected for alkaline environments. When the combustion temperature is around 1,000 degrees, clay products should be selected, between 1,200 and 1,400 degrees, high aluminum products should be selected, at around 1,600 and 1,700 degrees, corundum products should be selected, and above 2,000 degrees, special refractory materials should be selected.

Then, refractory materials are combined and applied according to the use location.

Different refractory materials are suitable for different parts of circulating fluidized bed boilers. The instantaneous temperature of the ignition air duct is high, so it is suitable for materials with high refractoriness and high thermal shock resistance. The temperature of the steering chamber in the dense phase area of the furnace, the furnace outlet, the furnace top, and the superheater is high, and the thermal shock is strong. Suitable for refractory materials with high wear resistance, high thermal conductivity, and low refire line change rate. The temperature at the inlet of the separator is high and the smoke velocity is high. The refractory materials in this part need stronger wear resistance and thermal shock resistance.

Finally, consider cost and performance-to-price ratio and choose affordable refractory materials.

The prices of refractory materials with different qualities and properties vary greatly. When selecting materials, the cost-effectiveness of the materials should be considered, and higher-quality refractory materials should be selected in high-temperature sections, ultra-high-temperature sections, and areas with severe corrosion. In the medium and low-temperature sections and parts that are weakly eroded, more economical and affordable refractory materials can be selected while meeting the needs of the working conditions.

It can be seen that when selecting refractory materials, more comparisons should be made in terms of material type, quality, cost, etc. Then choose a company with strong comprehensive strength.
