Shaft Seal 1000KW Electric Steam Heater Industrial Use

Product Specification

Shaft Seal Electric Heater of Mineral Insulated Heating Cable for Steam is a special electric heater based on mineral insulated heating cable elements for the shaft seal steam heater. 

The saturated steam can reach the process required temperature by reheating through the electric heater to get high temperature superheated steam under low pressure. When the temperature of the medium reaches the set value required by the process, the internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor at the outlet end.

Mineral Insulated Shaft Seal Electric Heater for Steam :

1. Brief introduction to Mineral Insulated Shaft Seal Electric Heater for Steam:

The saturated steam can reach the process required temperature by reheating through the electric heater to get high temperature superheated steam under low pressure. When the temperature of the medium reaches the set value required by the process, the internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor at the outlet end.

Two, Application Scope of Mineral Insulated Shaft Seal Electric Heater for Steam:

In thermal power industry, without the condition of suitable start auxiliary steam source for the shaft seal system of circulation turbine, the problem of low steam temperature of the shaft seal can be solved by the configuration of a shaft sealing steam electric heater. Therefore, start-stop times and service life of the steam turbine can be guaranteed. the boiler combined circulation start time under the conditions of cold or warm situation is greatly shortened.

Three, Characteristic of Mineral Insulated Shaft Seal Electric Heater for Steam

1, small size, large power;

Mineral insulated heating cable elements are used inside the shaft seal steam electric heater, and the maximum power of each heating element is up to 2000KW while the dimensions have been greatly compressed.

2, Fast thermal response, high temperature control accuracy and high comprehensive thermal efficiency;

3, wide application range and excellent adaptability;

Shaft seal steam electric heater can be applied to explosion-proof or ordinary occasions with explosion-proof grade up to class B and class C and pressure up to 20MPa.The cylinder can be installed vertically or horizontally according to the needs of projects.

4, high heating temperature;

The maximum working temperature of shaft seal steam electric heater can reach to 650℃ even higher, while regular electric heater cannot obtain.

5. Full automatic control;

Through the circuit design of shaft seal steam electric heater, it is convenient to realize the automatic control of outlet temperature, pressure, flow and other parameters, and can connected to computer to realize man-machine dialogue.

6, long life, high reliability;

The safety and service life of the shaft seal steam electric heater has been greatly increased because it is made of special electric heating materials, designed with conservative power load and secured with multiple protections.
