YLW- 2400T type thermal oil boiler is horizontal square box structure, using mechanized chain grate. YLW series thermal oil boiler heating surface by φ76×4mm and φ38×3mm two specifications of 20(GB/T3087-2008) seamless steel pipe manufacturing. The inlet and outlet container of organic heat carrier furnace is made of 20(GB/T3087-2008), φ159×6mm seamless steel tube.
This series of thermal oil boiler medium is driven into the inlet header by circulating oil pump. The inlet header is connected with the inlet of 25 φ38×3mm serpentine convection tubes, and the outlet of serpentine convection tubes is connected with another convective radiation header. Rectangular radiation coil is made of 4 φ76×4mm 20(GB/T3087-2008) seamless steel tubes coiling at the same time, the inlet is connected with the convection radiation box, the outlet is connected with the furnace top tube. The top pipe system is composed of 4 φ76×4mm 20(GB/T3087-2008) seamless steel tubes, whose inlet is connected with 4 radiation tubes, and whose outlet is connected with the outlet collector box. Medium in the serpentine convection tube, rectangular radiation coil tube and furnace top tube to absorb heat into the upper outlet container tube, is sent to the heat equipment.
YLW series chain grate boiler from the oven door to incarnate in material pellet fuel into the grate, the burning in the hearth, the flue gas after combustion after door shape pipe, ceiling absorption of heat, high temperature flue gas by the chamber of a stove or furnace exit in convection bank to form a second return, finally through the smoke outlet flue gas into the back of the flue, in turn after the flue, heat exchanger, induced draft fan, dust catcher into the chimney, Finally, it is discharged into the atmosphere through the chimney. Organic heat carrier furnace furnace adopts double dense coil tube, heating surface layout is sufficient. Strengthen furnace tube heat transfer, improve thermal efficiency. The boiler adopts automatic temperature control system to achieve accurate and stable temperature regulation to meet different requirements. Boiler heat preservation performance is good, using light heat preservation material, heat dissipation loss is small.
YLW series thermal oil boiler convection section adopts unique wrong type arrangement, improve flue gas heat exchange, and is not easy to accumulate ash. Medium process reasonable heat conduction oil from low (inlet) to (outlet) in the operation of the gas is difficult to stay in the furnace, can be convenient to remove the system. The boiler arch design is reasonable, the flue gas stays in the furnace for a long time, and the combustion is more full. The heating surface is arranged in the smoke room, so that the next door can avoid the direct erosion of high temperature flue gas, and effectively prevent the short circuit phenomenon of flue gas caused by the falling off of the smoke separation wall. The heating surface of boiler body adopts single furnace or double furnace densely arranged square coil rear force serpentine convection heat exchange tube.
The tail of the chain grate thermal oil boiler is configured with air preheater, steam waste heat boiler and hot water economizer to recover waste heat, reduce the exhaust temperature, improve the heat efficiency of the pot, reduce fuel consumption and save energy. According to the characteristics of fuel, measures are adopted in the convection heat exchange section of the boiler, such as high and low stagger arrangement, large spacing and arrangement of ash blowing device and ash cleaning device, so as to reduce ash accumulation and improve boiler efficiency. Organic heat carrier furnace heating surface pipe butt to automatic gas protection welding process and equipment, real-time X-ray online detection welding. The welding quality is stable and reliable. Large boilers adopt partial integration, on-site assembly. High integration, quick and convenient site installation.
