ROOF-MOUNTED INSTALLATION FOR CLEANING AND RECYCLING OF FLUE GASES Russian patent published in 2023 - IPC E04H12/28 F23J15/02 

FIELD: thermal power engineering.

SUBSTANCE: invention can be used to clean the flue gases of rooftop boiler houses from harmful impurities and utilize their heat and water vapour condensate. The roof-mounted installation for cleaning and recycling of flue gases ensures the purification of the flue gases of the heat generator of a roof-top boiler house from harmful components without the use of expensive and dangerous chemicals, using slag pumice granules as an adsorbent, made from basic metallurgical slags with a basicity module M>1, and water for adsorbent regeneration as a flushing agent, due to the fact that the box is perforated with holes, partially covered from below by inclined strips, connected on one side with the above-mentioned holes with an angle of inclination of the opposite side relative to the roof plane equal to 45° and directed in the direction of flue gas movement, water from atmospheric precipitation is used, it allows you to simultaneously utilize the heat of flue gases and water vapour condensate, which reduces the load on the chemical water treatment unit, provides an autonomous water supply to the boiler room for replenishing the steam generator and regenerating the adsorbent, and also allows for adsorbent regeneration processes to be carried out with high reliability and efficiency without stopping the heat generator.

EFFECT: increase in the reliability and efficiency of a roof-mounted installation for cleaning and recycling flue gases.
