The operation of the Urid incinerator is highly complex due to the varying nature of the combustion materials, which may not necessarily be acidic or alkaline. Consequently, the refractory lining of the furnace is subject to severe erosion, and its service life is affected by uncertain factors.

Each item has a finite lifespan and will eventually become unusable due to damage over time, and incinerators are no exception. The operation of incinerators is highly complex, as the properties of the material after incineration can vary, not necessarily being acidic or alkaline. Consequently, the refractory material used for the lining is subject to severe erosion, and its lifespan is affected by unpredictable factors.

The erosion of the atmosphere within the incinerator, operational temperatures, and uncertainty of the melt pose certain requirements for refractory materials.

What are the specific factors that affect the lifespan of incinerators?

Firstly, the effect of furnace atmosphere on refractory materials. Generally, incinerators are in an oxidizing atmosphere, but occasionally the height of the gas flow can slightly alter the temperature and pressure. Silicon carbide materials exhibit superior corrosion resistance in reducing atmospheres, making the selection of silicon carbide an excellent choice.

Next, there's the impact of temperature. Incinerator temperatures can reach up to 1400°C, with increasing temperatures leading to greater corrosiveness. Generally, incinerator temperatures hover around 1100°C, yet the corrosiveness should not be overlooked. Clay bricks and high-alumina bricks are more sensitive to temperature. However, high-alumina bricks can still be a good choice when temperatures do not exceed 1200°C.

There is also the impact of silicon dioxide. Incinerators tend to produce slag, primarily alkaline in composition, but sometimes it also contains unknown substances, which could be acidic. This means neutral materials can be affected. If calcium and silicon dioxide increase, so does the corrosiveness, hence the need for silicon carbide bricks for corrosion prevention.

In summary, service life is greatly related to temperature and corrosion. If the temperature is below 1200°C, high-alumina series can be used, as can silicon carbide castables or bricks. Of course, the insulation material should be chosen based on the situation. Fiberboard or insulating castables can be utilized.

Daily cleaning of equipment is essential. Although these devices assist businesses in achieving a secondary pollution-free treatment of waste and by-products, they require timely cleaning of the furnace for reuse. Of course, the cleaning process must be carried out meticulously by staff. Besides cleaning the interior furnace, the exterior surface should not be overlooked. More importantly, regular cleaning of both the interior and exterior of the equipment plays a crucial role in its specific usage.
