Basic knowledge of tube heating furnace

 What is combustion? What are the basic conditions for combustion? Answer: Combustion is a process in which substances combine with each other and produce light and heat. What we usually call combustion refers to the violent chemical reaction between combustibles and oxygen in the air. A certain temperature is required when a combustible material burns. The minimum temperature required when a combustible material begins to burn is called the ignition point or ignition point of the material.Application of sintering technology in semiconductors The basic conditions for material combustion: first, combustibles, such as fuel oil, gas, etc.; second, there must be combustion accelerants, such as air, oxygen; third, there must be an open flame or a high enough temperature. Combustion cannot occur without one of the three. This is the "three conditions of combustion" or the "three elements of combustion".Effect of vacuum heat treatment on the properties of powder metallurgy products What are radiation heat transfer and convective heat transfer? Answer: Radiation heat transfer is a process of transferring energy by electromagnetic waves. The energy transferred is called radiant energy. Radiation has dual properties of particulate (photons) and wave (electromagnetic waves).
