The service life of the ceramic fiber blanket is closely related to the fuel of the kiln. The type of fuel and the combustion mode of the kiln will directly affect the temperature and atmosphere in the kiln, which will affect the service temperature and service life of the ceramic fiber blanket.
First of all, the type of fuel in the kiln has an important influence on the service temperature of the ceramic fiber blanket. Different fuels have different calorific values and combustion characteristics, so the heat and temperature produced are also different. For example, when using clean fuels such as natural gas or liquefied petroleum gas, the temperature in the kiln is relatively low and the temperature fluctuations are small, which helps to extend the service life of ceramic fiber blankets. When using solid fuels such as coal and coke, the temperature in the kiln is relatively high and the temperature fluctuates greatly, which will adversely affect the service life of the ceramic fiber blanket.
Secondly, the way the kiln burns will also affect the service temperature and service life of the ceramic fiber blanket. Different combustion methods produce different flame and hot gas distributions, which affect the temperature and atmosphere inside the kiln. For example, when using advanced combustion methods such as preheated air or oxy-fuel combustion, temperature fluctuations in the kiln can be reduced, and the occurrence of high temperature spots can be reduced, which is conducive to extending the service life of ceramic fiber blankets. However, when the traditional combustion method is adopted, due to the uneven distribution of flame and hot airflow, it will lead to local high temperature spots in the kiln, which will accelerate the aging process of ceramic fiber blanket.
In addition, the fuel combustion efficiency and heat recovery efficiency of the kiln will also affect the service temperature and service life of the ceramic fiber blanket. If the fuel combustion efficiency is low or the heat recovery efficiency is low, the temperature in the kiln will be too high or fluctuate too much, which will accelerate the aging process of the ceramic fiber blanket. Therefore, when selecting kiln fuel, it is necessary to comprehensively consider its calorific value, combustion characteristics, combustion mode, fuel combustion efficiency and heat recovery efficiency and other factors to select the appropriate fuel and combustion method, so as to prolong the service life of ceramic fiber blanket.
In summary, the use temperature of ceramic fiber blanket is closely related to the fuel of the kiln. In order to extend the service life and improve the safety of ceramic fiber blankets, it is necessary to choose the right fuel and combustion method, and optimize the design and control of the kiln. At the same time, appropriate measures need to be taken according to the actual situation to improve its service life and safety during use.
