The electrically heated water bath liquid ammonia evaporator is used to supply ammonia gas in the flue gas denitrification system of thermal power plants and chemical plants. Liquid ammonia enters the electrically heated water bath evaporator through a stainless steel heat exchange coil. Through the heat exchange of the heat medium, the liquid ammonia is heated and evaporated to around 40C, forming gaseous ammonia and supplied to the denitrification system. The heating source of the heat medium is a controllable and efficient explosion-proof electric heater. The explosion-proof electric heater continuously changes the power of the heater through temperature feedback inside the container, ensuring that the temperature inside the container remains within the set range without significant temperature deviation, Ensure the provision of stable heat sources.
■Equipment Composition
The electrically heated water bath ammonia evaporator is composed of
1、Stainless steel heat exchange coil (the heat exchanger is made of seamless stainless steel pipes without circumferential seams, with a design pressure of 1.6MPa and liquid ammonia inlet)
2、External shell container (non pressure container for storing heat medium)
3、Explosion proof electric heater
4、Gas ammonia separator
5、Other related accessories (valves, temperature sensors, pneumatic control valves, temperature switches, etc.).
6、Composition of temperature control cabinet, auxiliary equipment, etc.
The container is equipped with on-site display of the liquid level of the heating medium, remote transmission of the temperature of the heating medium, and other related signal collection points.
