Product Introduction
The YLW series thermal oil boiler is a horizontal chain grate assembly boiler with a square coil design. The chain grate and the boiler body are separated at the factory. This boiler utilizes a chain grate for mechanical coal feeding, equipped with blowers and induced draft fans for mechanical ventilation, and features a slag removal machine for mechanical slag discharge. During operation, fuel falls from the coal hopper onto the grate for combustion. The high-temperature flue gas is reflected to the front of the furnace after passing through the arch, then undergoes radiant heat exchange over the radiant heating surface. It subsequently enters the convective heating surface for convective heat exchange, and is then directed to the waste heat boiler. Afterward, it moves to the air preheater, and finally enters the dust collector. Once cleaned, the flue gas is drawn by the induced draft fan through the chimney and released into the atmosphere.
Technical Advantages:
Digital Manufacturing
The down-sloping steel pipes are cut using a CNC three-dimensional laser cutting machine.
The square pipe is manufactured using CNC 3D bending machines, without forced assembly.
The manufacturing of serpentine tubes is done using an automatic serpentine tube production line, forming in one go.
Full Argon Arc Welding
Serpentine pipes and square pipe baskets are both焊接 using the argon arc welding process, ensuring compliance with quality standards.
Long lifespan
Optimized radiant and convective heating surfaces, with a more rational medium flow, which won't reduce lifespan due to overheating of the carrier.
The heating surface utilizes an effective fixation and support structure, extending its service life.
Effective smoke isolation is set for the heated surface of the heat exchanger, ensuring a longer lifespan for the partition walls.
Operation is simpler
Patented arch structure, suitable for various coal types, including anthracite, which burns just as well.
Fuel斗 cover, effectively prevents biomass fuel斗 from burning and coking.
Establish an effective dust removal structure for easy maintenance, operation, and cleaning.
Fuel more efficient
Fired with refractory bricks, filled with perlite in the middle, the furnace body temperature is maintained below 50°C, with minimal heat loss.
The furnace adopts double-density tray pipes for the heating surface arrangement.
