625 Cladding 310 Stainless Steel Superheater And Reheater ASME Standard

The role of cladding

(1) Can effectively improve wear resistance and corrosion resistance, so as to prolong the life of parts.

(2) easy to make a very hard metal surface on a good toughness base metal, from where to obtain the best performance.

(3) The economical use of precious alloy materials, reduce manufacturing costs.

(4) Can save the cost of maintenance and replacement of parts for enterprises.

Superheater Description

Super heaters are the one of the most important boiler sapre parts that improves the thermal efficiency. High temperature steam boiler radiant super heater is usually applied in high pressure power plant boiler. In the boiler, the role of super heater is to heat the saturated steam to a certain temperature of superheated steam to increase power plant efficiency. Repeater essentially further improves the thermal power plant cycle efficiency. Steam Super heater Coils: Super heater coils are used in a boiler to generate saturated steam. The super heater coils are specially used in Boilers of Power plant. We manufacture Super heater coils in various grades of Alloy steel and in stain less steel tubes with or without support & Header as per customer's drawing.

Superheaters are a set of tubes located in the boiler. Steam from the water walls passes to the superheaters where it is heated above its saturation temperature until the maximum required operating temperature is achieved. The superheated steam then flows through the main steam piping to the high-pressure turbine. Exhaust steam from the high-pressure turbine is guided to the boiler for reheating and from there to the intermediate and low-pressure turbines. High reheating temperatures improve the output and efficiency of a power plant.

Classification

Super Heater Types:

A radiant superheater is placed directly in the combustion chamber.

A convection superheater is located in the path of the hot gases.

A separately fired superheater, as its name implies, is totally separated from the boiler.

Radiant superheaters are located directly within the combustion chamber of the boiler itself. This arrangement allows for the burner from the boiler to heat both the boiler tubing and the superheater tubes, making radiant superheaters highly effective devices. These are most commonly found in steam power plants and also were widely used in steam automobiles.

Convection superheaters are most commonly found on locomotives. Much like a convection oven, this type of superheater utilizes the hot gases from the burner to reheat the steam. A convection superheater can be extremely efficient, because most of the thermal energy is given only to the boiler tubing. These are also found in power plants, but they were mostly implemented in steam locomotives.
