YLW series coal-fired thermal fluid heater

Fuel falls on the grate from coal bucket during operating and burning, high temperature smoke enters furnace by passing combustion arch, after radiation heat exchange, smoke enters convection heating surface for convection heat exchange, then goes to waste heat boiler and air heater, at last enters dust collector then is vented into the atmosphere through chimney by induced draft fan.

Technical advantages

Digitized manufacture

• The laying-off of steel tube adopts CNC 3D laser cutting machine.

• The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.

• The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.

full argon arc welding

• Square coil tube and coil tube all adopt argon arc welding technique,which guarantees tubes are 100% qualified.

Long life span

• The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;
