Boiler Spare Parts Superheater For Utility Power Station High Efficiency Heat Exchanger hot water boiler

Boiler Spare Parts Superheater Features

1. As outstanding features, Heat Efficiency Improving boiler parts reheater for Steam Boiler have beautiful appearance, accurate sizes, advanced bending and welding technique, first-lass testing equipment and guaranteed quality.

2. The function of Super heater in the thermal power plant is to remove the last traces of moisture from the saturated steam coming out of boiler and to increase its temperature above saturation temperature as per requirement at inlet of steam turbine.

Brief Introduction

1. Generally 30 ~ 60 mm.The most common type of flow superheater is serpentine tube.It has a more intensive tube group, decorate in 450 ~ 1000 ℃ flue of the flue gas temperature, flue gas of vertical and lateral erosion.The flue gas mainly transfers the heat to the pipe by convection, and some of the heat is absorbed by radiation.

2. The plate-type superheater consists of a plurality of tube screens, arranged in the upper part of the furnace or at the outlet, belonging to the radiation or semi-radiation type superheater.The former absorbs radiant heat from the furnace flame, while the latter also absorbs some convection heat.
