Description

Steam superheater convenient to maintain

Technical Field

The utility model relates to a waste heat recovery equipment technical field specifically is a steam over heater convenient to maintain.

Background

The superheater is a part in the boiler that further heats steam from a saturation temperature to a superheat temperature, and is also called a steam superheater. The superheater can be divided into a convection type, a radiation type and a semi-radiation type according to the heat transfer mode, and can be divided into a serpentine tube type, a screen type, a wall type and a wall-wrapping type according to the structural characteristics. They are all composed of a plurality of parallel pipes and inlet and outlet headers. Most industrial boilers are not equipped with superheaters, since many industrial processes and living facilities only require saturated steam. In power stations, locomotives and marine boilers, superheaters are generally installed to improve the cycle thermal efficiency of the entire steam power plant. The water content in the exhaust steam of the steam turbine can be reduced by adopting superheated steam. The temperature of the superheated steam depends on factors such as the pressure of the boiler, the evaporation capacity, the high temperature resistance of steel, the fuel-steel ratio and the like, and for a power station boiler, a boiler with four megapascals is generally about four hundred fifty degrees centigrade, and a boiler with more than ten megapascals is from five hundred forty degrees centigrade to five hundred seventy degrees centigrade. A few utility boilers also use higher superheated steam temperatures.

Most of steam superheaters used in the current market are fixed in structure, the pipeline inside the steam superheater is fixed with the shell structure of the superheater, the disassembly is difficult, when partial pipelines of the steam superheater are blocked or damaged, the pipeline is fixed with other pipeline structures or is not convenient to disassemble, so that the whole steam superheater is difficult to maintain, the resource waste is caused, and the practicability of the steam superheater is reduced.
