The relationship between the structures of furnace raw materials and furnace construction will be introduced in this paper.
heat transfer properties of raw materials are important factors affecting the efficiency, fuel consumption and air volume of boilers. It is necessary to choose the raw materials suitable for the boiler according to the performance of the materials and the structure of the furnace. This paper focuses on the relationship between the properties of furnace raw materials and furnace construction.
First, according to the type of boiler, the raw materials needed are different. For water tube boilers, due to the high temperature and pressure, steam and water flow between the tubes, so the raw materials must have higher heat transfer ability, namely heat transfer coefficient. Secondly, for fire tube boilers, the wall thickness and length of the tubes directly determine the heat transfer area, so the raw materials must have higher thermal conductivity.
In addition, it is important to consider how the properties of the raw material affect the construction of the furnace. For example, when selecting raw materials for furnace structure, the thermal conductivity of the raw materials is usually between 1-10 w/mk. At the same time, different raw materials also affect the combustion efficiency, fuel consumption and air volume of the furnace. For example, the highest heat transfer coefficient can be obtained by using a mixture of materials with low heat transfer coefficient and small heat capacity.
In conclusion, it is important to consider the properties of raw materials when constructing a boiler. Different properties of the raw materials will affect the boilers’ efficiency, fuel consumption and air volume, as well as the overall structure. Selecting raw materials with the right properties is key to efficient furnace design and operation.
