The type of viewing port is determined by the design of the furnace. Flat, square viewing ports are commonly used on boilers, while rotary, circular viewing ports are used in other cases; there are also slide-door types, among others. Negative-pressure furnaces have lower requirements regarding viewing ports, whereas positive-pressure furnaces have higher requirements. On one hand, the safety of the operators must be taken into account, and on the other hand, the sealing performance of the furnace must also be considered； Additionally, industrial furnaces also have mica viewing ports, etc.; the specifics depend on the conditions of the furnace!
