Application of gas oil fired 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 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.
