coal-water slurry fired steam/hot water boiler is the
new-generation environmental-protection product. It features Iow
fuel cost and less contamination emission. Therefore it is the
ideal substitution of oil and coal boiler. It is the
free-circulation, inside combustion, water tube steam boiler that
makes the combustion at little negative pressure and balanced
ventilation. There are two boiler cylinders at the upper and lower
levels longitudinally. Burner is mounted on the front wall and
coal-water slurry fires sufficiently in the hearth (combustion
efficiency >*8%). Generated hot fume flushes the convection tube
bank adversely via the hearth outlet. Heat of hot fume is exchanged
in the air pre-heater at the rear of boiler. Then hot fume is
treated with desulfurization dust collector and drained outside
with chimney via the draught fan.? High
combustion efficiency of coal-water slurry (>*8%) and design
heating efficiency (close to *0%).? Emission
conforms to the environmental-protection requirements for Class I
zone, Emission Standard of Boiler Contaminates.? Adopt
the front stable-combustion hearth and reasonable section and
volume so that boiler is applicable for various coal-water slurries
and hearth is protected effectively against coking.
