YLW series boiler is a square coil horizontal chain grate assembly boiler, chain grate and boiler body separate from the factory, after the site is in place, just put the oil, electricity can be put into operation, the furnace using chain grate Mechanical coal, equipped with drums, induced draft fan for mechanical ventilation, and equipped with slag machine to achieve mechanical slag.
During the operation, the fuel falls from the coal hopper to the grate for combustion. The high-temperature flue gas passes through the rear arch and enters the furnace in front of the furnace. After radiative heat exchange on the radiant heating surface, it enters the convection heating surface for convection heat transfer, and then leads to waste heat. The boiler enters the air preheater and enters the precipitator. After the dust is removed, the exhaust gas is drawn by the induced draft fan through the chimney to the atmosphere.
The boiler heating surface consists of four parts: the radiant heating surface of the furnace, the convection tube bundle heating surface, the waste heat boiler, and the air preheater (economizer).
- Adopt advanced structural style to optimize radiation heating surface and reduce the formation and discharge of flue gas dust in combustion room
- According to the characteristices of organic heat carrier boiler and various kinds of coal,design various kinds of combustion room adapt to II,III bituminous coal, anthracite,sorts of biomass fuel.
- Set up effective flue gas partition for convection heating surface and cast partition to make it work longer and more effectively
Coal-fired heat-conducting oil furnaces are widely used in petrochemical industry, textile printing and dyeing industry, plastics and rubber industry, paper industry, grease industry, synthetic fiber industry, timber industry, man-made board, fiberboard hot pressing molding, drying, uninterrupted steaming all year round, building materials Industry mineral wool board processing, gypsum board drying, asphalt heating, candy processing, candied fruit processing, dried noodle drying, food industry, biscuit drying, oil pressing and beverage drying, paint and other heat sources below 350 degrees Celsius, food processing , wood processing, asphalt heating, carton production, vegetable dehydration, paint, sand mold drying and so on.
- With low pressure and high temperature characteristics.
- Stable heating, precise control of temperature.
- Keep thermal efficiency at an optimal level.
- Complete operation control and safety monitoring device.
- Reduce other consumption, save electricity, water and oil
- Each welding seam has undergone rigorous polishing and rust removal before welding to ensure that the weld is 100% qualified at one time. (Plumbing end polishing, head machining, barrel ring joint, longitudinal joint, pipe hole, derusting map)
- Fully digitally controlled four-roller coiler, completes a roll-to-roll system in 1 minute and 30 seconds, and the out-of-roundness and angular misalignment are accurately controlled within 1, mm. (with roll plate video or picture
- 28 submerged arc automatic welding, matching different diameters and thickness of the cylinder, so that each weld has a precise welding parameter corresponds.
- The patented threaded tobacco tube machine uses infra-red to measure the thread depth to ensure proper thread taste depth and strict guarantee of heat transfer coefficient and service life.
