Coal-fired thermal oil boiler is an assembled forced circulation chain grate boiler. The front part of the boiler body is the radiant heating surface of the furnace, which is composed of double square coil tubes. The rear part is convection. The middle brush heating surface consists of a serpentine tube bundle. Thermal oil boiler feature prominent, easy installation, as long as the upper body and the lower grate closed, short installation cycle.
YLW series industrial boiler by the upper body and the lower chain grate composition, site combination. The air preheater is arranged behind the boiler. The high temperature flue gas generated by combustion is absorbed part of the heat in the furnace, and enters the convection heating surface for heat exchange through the smoke chamber. Then, the flue gas is heated in the air preheater and sent to the chimney by the induced draft fan through the dust collector and discharged into the atmosphere.
Thermal oil boiler feature has obvious, the furnace adopts double close row coil tube, and the heating surface arrangement is sufficient. The boiler can reduce the heat load on the surface of the pipe, so that the heat conducting oil can be used. The medium flow is reasonable, the heat conduction oil is from low (inlet) to high (outlet), the gas produced by operation is difficult to stay in the furnace, and can be conveniently discharged from the system. The design of the furnace arch of this series of thermal oil boilers is reasonable, the flue gas stays in the furnace for a long time and burns fully.
This series of boiler products to smoke chamber layout heating surface, so that the partition wall to avoid high temperature flue gas directly scour, effectively prevent the flue gas short circuit phenomenon caused by the falling off of the wall. The whole boiler is made by digital manufacturing, and the steel tube is made by CNC 3D laser cutting machine. Square plate control machine adopts numerical control three-dimensional pipe bender, no forced assembly. Serpentine tube automatic production line, one – time forming.
Coal fired thermal oil boiler can adopt full argon arc welding mode, serpent tube and square coil tube all adopt argon arc welding technology, to ensure 100% qualified. Optimized radiation heating surface and convection heating surface, more reasonable medium flow, will not reduce the life of the carrier due to overheating. Convection heating surface with effective fixed and support structure, so that the service life is longer. Effective flue gas isolation is set on convection heating surface, and the service life of pouring partition wall is longer.
Thermal oil boiler feature prominent, the use of patented furnace arch structure, suitable for different kinds of coal, anthracite is also good to burn. Prevent fuel hopper is set to effectively prevent biomass burning hopper and coking. Equipped with effective dust removal structure, convenient maintenance, operation and cleaning. Adopt high quality firebrick masonry, with high quality perlite in the middle, the furnace temperature is controlled below 50℃, and the heat loss is minimum. The furnace adopts double close row coil tube, and the heating surface is sufficiently arranged. Zozen Boilers specialize in producing high quality boiler products, mainly providing customers with high quality boiler service.
