Working principle

YY (Q) W series thermal oil boiler (organic heat carrier furnace) is a fast loading horizontal forced circulation oil (gas) thermal oil boiler (organic heat carrier furnace). The fuel is burned and released in the combustion chamber composed of inner tubes. After most of the heat is absorbed by the radiant heating surface, the high temperature flue gas enters the convective heating surface for heat exchange. The flue gas after heat exchange is discharged through the flue gas outlet of the furnace body, enters the air preheater, and fully exchanges heat with the air. The flue gas after heat exchange enters the condenser for heat exchange with water. Finally, the flue gas temperature is reduced to below 100℃ and discharged into the atmosphere through the chimney.
