YYL type vertical fuel (gas) heat transfer oil furnace
Heat supply: (300-1500) × 104Kcal / h, design pressure: 1.1MPa
YYL (YYW) series organic heat carrier furnace is a fast-installed forced circulation fuel (gas) boiler. The heating surface of this series of boiler body has a compact structure. The heating surface is composed of inner, middle, and outer (or inside and outside) close-packed circular coils. The inner coil is a radiant heating surface. The surface forms a convective heating surface. The fuel emits heat in the combustion chamber composed of inner coils. After absorbing most of the heat through the radiant heating surface, the high-temperature flue gas enters the convection heating surface for heat exchange. After exiting the boiler, the air required for the boiler combustion is heated in the air preheater , And then the dust is sent to the chimney by the induced draft fan and discharged into the atmosphere.
Installation is extremely convenient and flexible, as long as the boiler is on its foundation.
The heating surface adopts close-packed coiled tubes. The heating surface is adequately arranged to reduce the heat load on the surface of the tube. It is safer to use heat transfer oil.
The size of the furnace is matched with the combustion flame. Positive pressure combustion is used, and the radiation heat transfer efficiency is high.
The compact structure of the boiler greatly saves the floor space of the boiler room.
An air preheater is installed at the rear of large boilers to improve boiler efficiency.
