Superheater - Wikipedia

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet

dongguan high pressure boiler tube offer

High pressure boilers use water-tubes since fire-tubes are not sufficient in regards to pressure or temperature even if the boiler were larger and burned more fuel. In order for fire-tube boilers to create the same amount of pressure the system would require thicker walls and bigger tubes but still would not be able to reach high enough

Is superheated steam pressure and temperature the same as

No it isn't. Superheated steam cannot exist in a boiler drum, it can only exist in a moving fluid. This is why the superheater tubes are separate from the rest of the boiler tubes, where the steam has to be moving to have heat imparted to it. If t
