vertical assembly forced circulation coal-fired boiler description

YGL(YLL)series of organic heat-medium boiler is the vertical assembly forced circulation coal-fired boiler.The compact heating area comprises of inner and outer closely-aligned round coils.Inner coils are the radiation heating area and outer coils serve the convection heating area with external surface of inner coil. Boiler is structured into the body drum on the combustion chamber,which shall be assembled on site.Fuel burns thoroughly in the combustion chamber.Most heat is absorbed by the radiation heating area and residue hot fume flows in the convection in the air preheater. Finally it exhausts outside through chimney via the dust collector and draught fan.

vertical assembly forced circulation coal-fired boiler features

  • Easy to install, it will be enough if jointing the upper proper and bottom fire grate, short installation cycle.
  • Heating surface uses round closepacked coil, sufficient heating surface design can reduce surface thermal load, and then keep heat transfer oil safer.
  • Scientific medium flow, the heat transfer oil flows from lower(inlet) to upper(outlet), air produced in the process of traveling will be hard to stay in boiler, and can be drained away from system conveniently.
  • Combustion in combustion chamber is an adiabatic combustion, it will be easy to ignite and burn fuel, make it burn sufficiently, and improve thermal efficiency of boiler.
  • The top of boiler is designed closepacked coil, it can protect the roof of boiler well, avoid it from burning out.

vertical assembly forced circulation coal-fired boiler advantages

1. Strong adaptability of different fuels

separated design for combustion equipment and upper furnace, according to the different nature of the solid fuel, furnace can be design individually .

2. Diversity of grate structure

The structural grates has fixed and moving types, depending on the fuel nature, it can be manual or mechanical feeding .

3. Large diameter combustion chamber

Boiler combustion chamber is composed of vertical large diameter circular tube, the coil structure with series or parallel, with large fuel combustion space, complete combustion, high thermal efficiency.

4. Best coil design

Furnace internal and external spiral coil is made of bulls, small diameter steel pipe coil thermal expansion of good performance, low stress, safe and reliable.

5. Optimal process design

Three return flue gas, medium flows through the inside and outside coils, with uniform velocity, safe and stable operation

6. Sufficient output

Reasonable heating surface layout, large area, good heat transfer effect, high efficiency, stable output, sufficient.

7. Perfect automatic control measures

precision control on outlet oil temperature , multiple protection and control are set on medium temperature, pressure and smoke temperature to ensure safe and reliable operation.

8. leading technology on automatic control
Boiler controller adopts Siemens/ Schneider electric components, reliable in performance. Controller has three forms: normal, LCD display in English menu, and equipped with touch screen man-machine dialogue remote control.
