SZL packaged water-tube steam boiler is the
double-cylinder,water-tube assembly,chain grate boiler.Two
cylinders are laid at the upper and lower level of boiler
longitudinally along the center.Front section of the upper cylinder
and water-cooled tubes at side walls form the radiation-heating
area in the hearth.While the rear section and tube bank in the
lower cylinder serve as convection-heating area.Coal econnomizer is
mounted at the rear of bolier.Some heat of hot combustion fume is
absorbed by the hearth.Then hot combustion heat flows to the
convection heating area through cooling chamber and exhausts
outside with the chimney via coal economizer,dust collector and
draught fan.
Great assembily level,short installation period and cheap
installation.
Sufficient and reasonable heating area,quick
temperature/pressure-rise of boiler,satisfactory productivity and
high heating efficiency.
Introduce the air with air distribution chambers of grate.All air
distribution chambers can adjust the air flow indepedently and
grate speed can be regualated in the stepless way.Wide range of
applicable coals.Thorough combustion.
Electrical cabinet is equipped with complete automatic control and
monitor instruments featuring high automation,safety,reliability
and simple operation.
