Steam heating water type liquid ammonia evaporatoris widely used in DeNOx device in the coal-fired power plant. Liquid ammonia through stainless steel into hot water which is heated by steam , through heat energy transfer to liquid ammonia and then will be vaporized into ammonia.Steam inlet valve and the water temperature interlocking control the rate of vaporization , to adjust the steam flow , to ensure that the evaporated quantity of liquid ammonia.
    Electric heating type liquid ammonia evaporatoruses the electric heater to heat water,through heat energy transfer to liquid ammonia and then will be vaporized into ammonia.
