Aitesa will supply pressure vessels for the modification of boiler 621F501A at the Industrial Complex of Repsol Puertollano.
The modification will allow to reduce of flue gas temperature at outlet to 130ºC, improving the efficiency of the boiler and producing low pressure steam.
The modification consists of:
• the replacement of the current economizer and medium pressure vaporizer with a new medium pressure vaporizer and a new low pressure vaporizer, installed on the space available due to dismantling of the previous equipments.
• the installation of a new economizer at the impulsion of the flue gas fan at the boiler outlet in order to preheat the boiler water.
