YLL / YGL vertical coal-fired thermal oil furnace

Product Range

Heat supply: (60-200) × 104Kcal / h, design pressure: 1.1MPa

YLL (YGL) series organic heat carrier furnace is an assembled forced circulation vertical coal-fired boiler. The heating surface of this series of boiler body has a compact structure. The heating surface is composed of inner and outer close-packed circular coils. The inner coil is a radiant heating surface. The boiler consists of an upper body and a lower combustion chamber, which are assembled on site. After the fuel is fully combusted in the combustion chamber, the radiant heating surface absorbs most of the heat, and the high-temperature flue gas enters the convection heating surface for heat exchange. After exiting the boiler, the air required by the boiler is heated in the air preheater, and then the dust collector is used. Induced draft fan sends the flue gas to the chimney and discharges it into the atmosphere

Easy installation, as long as the upper body and the lower combustion chamber are closed, the installation cycle is short.

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 medium flow is reasonable, and the heat transfer oil is from low (import) to high (export). The gas generated during operation is difficult to stay in the furnace and can be conveniently discharged from the system.

The absolute combustion of fuel in the combustion chamber makes it easier for the fuel to catch fire and burns more fully, which improves the thermal efficiency of the boiler.

The top of the boiler is equipped with close-packed coils, which can better protect the top of the boiler and avoid the phenomenon of burnout of the top of the boiler.
