Factory Price 2ton Gas Fire Tube Steam Boiler for Paper Mills Industry
Application of Fire Tube Steam Boiler
1. Brewery / Brewhouse
In brewery, steam is used for drying green malt,
gelatinizing/saccharifing raw materials, boiling wort, fermenting
beer, and pasteurizing bottles. Otherwise, hot water is also used
for sanitization. Generally, the steam boiler with 0.5ton~2ton
capacity is enough for a brewery, while, based on the production
ability, the steam capacity is a little different. Sitong Boiler
provides various models of industrial steam boiler and hot water
that necessary to the brewery.
2. Rice Mill
In rice mill, industrial steam boiler is used for starch
liquidation and pasting. The needed steam pressure is between
0.3MPa and 0.6MPa. The best fuel for steam boiler is rice husk,
which can save cost. Sitong Boiler products different types of rice
husk boilers, including both horizontal type and vertical type
boilers with chain grate, moving grate, fixed grate, and
reciprocating grate.
3. Paper Processing Industry
In paper processing industry, there are many processes (drying,
corrugating, boiling, etc.) that need steam. For example, steam is
necessary for drying, after squeezing, the paper still contain a
large amount of water (53%~70%), then steam boiler is used for
drying paper, and combine used with the cast iron dryer.During the
processes of drying, boiling, and corrugating in paper industry,
steam is extremely necessary. 9 bar pressure steam boiler is used
for pulp boiling to decompose the plant fiber and change color.
Otherwise, accompanied used with cast iron dryer, steam boiler is
used for paper drying, to improve the paper strength.
Special design features of Fire Tube Steam Boiler
1. Adopt domestic and foreign advanced large furnace design
Increase the diametre of furnace on the basis of original
traditional design.expand the surface of radiant heat
exchange,mainly center on radiant heat exchange ,reduce the heat
exchange burden during the second and third return,and make the
fuel burning efficiently,reduce the harmful gas production.
Besides,the spiral hearth in the high temperature area not only
increase the area of radiant heat exchange, but also make a
resistance to the smoke movement.have a obvious effect about
radiation heat exchange.
2. Research PCL control board independently
Strontg conpatibility,PLC intelligent touch screen equipmet,10-inch
touch screen,fool-type operation,safe and reliable,automatic
ignition/flame-out/fire switch,high fired gas,low pressure
protection,gas leakage protection,filling and stopping pump
automatically,high and low water warning,ultra low water-level
interlock,alarm when the temperature of smoke exhaust is too high
and stop furnace operating.
3. Large load imported burner configuration
80% configuration ratio,light load drive,enough thermal energy
import,guaranteed output,reduce equipment use fatigue,extend the
service life,the quality of inlet valve group is steady and
reliable.
