High Temperature And High Voltage Electric Heater Heat Transfer Area Margin
Sep 27, 2017



High-temperature high-voltage electric heater is connected to the high-pressure feed pump after the heating water supply hybrid heater, used to improve the water supply temperature and improve economic efficiency.

Structural Characteristics of High Temperature and High Voltage Electric Heater

The high-temperature and high-voltage electric heater is composed of two parts of the shell and the pipe system. The steam condensation section is arranged in the upper part of the shell cavity, High Temperature And High Pressure Explosion-proof Electric Heater and the lower part is provided with the water supply and the water outlet at the top of the outlet pipe. When the superheated steam from the inlet into the shell after the upper part of the main pipe can be heated to the water, the steam condensed into water, High Temperature And High Pressure Explosion-proof Electric Heater the condensed hot water can be part of the lower part of the cold water pipe heating water, after the use of condensate The hydrophobic outlet flows out of the body. The device has the advantages of low energy consumption, compact structure, small occupied area, consumption of materials and other significant advantages, and can be more strictly control the hydrophobic water level, hydrophobic flow rate and reduce the hydrophobic end difference.

When the superheated steam from the inlet into the shell after the upper part of the main pipe can be heated to the water, the steam condensed into water, the condensed hot water can be part of the lower part of the cold water pipe heating water, after the use of condensate The hydrophobic outlet was spilled out of the body. High Temperature And High Pressure Explosion-proof Electric Heater The device has the advantages of low energy consumption, compact structure, small occupied area, consumption of materials and other significant advantages, and can be more strictly control the hydrophobic water level, hydrophobic flow rate and reduce the hydrophobic end difference.

First, the high temperature and high pressure electric heater is how to heat

High-temperature high-voltage electric heater is a tube plate heater, the flow of water in the tube, the steam turbine pumping in the tube outside the flow, High Temperature And High Pressure Explosion-proof Electric Heater relying on the flow of the two flow and heat will heat. The condensate (hydrophobic) after exotherm is removed by the trap to maintain a certain water level.

Yes, the high water pipe is a serpentine tube.

Second, the use of high temperature and high voltage electric heater:

High-pressure feed water heater is introduced from the steam turbine out of the steam to heat the boiler feed water, so that water to meet the required temperature, so as to ensure the unit's output and improve the thermal efficiency of power plant cycle.

Third, the high temperature and high voltage electric heater structure:

High pressure water supply heater in various forms, there are inverted vertical spiral pipe, vertical U-shaped pipe, horizontal U-shaped tube, heat transfer structure according to the different parameters were used one or two or three sections of heat transfer (superheated steam condensation Section, High Temperature And High Pressure Explosion-proof Electric Heater saturated steam condensing section and hydrophobic cooling section), and configure the security protection control equipment.

Fourth, the characteristics of high temperature and high voltage electric heater:

1, the temperature difference is small

2, heat transfer area margin

3, anti-red device with stainless steel baffle

4, tube with anti-vibration measures

5, High Temperature And High Pressure Explosion-proof Electric Heater the strength of reliable

6, tube and tube plate expansion and welding quality and high efficiency

7, tube plate surfacing

8, High Temperature And High Pressure Explosion-proof Electric Heater the end of the heat transfer tube with stainless steel anti-wear casing

9, nitrogen protection
