Rice husk fired steam boiler application
Food Industry Industry steam boiler for food & beverage industry is used in the
processes of distillation, sterilization, disinfect, extraction,
drying, and curing, etc. The boiler should be clean and
environmental protection, so, it is better to use the clean energy
as the fuel, such as natural gas, biomass fuel, and electricity.
The suitable boiler could be horizontal type oil gas fired fire
tube boiler, biomass fired chain grate water tube boiler. During
the process of distillation, disinfect, drying, sterilization and
curing in food processing industry, industrial steam boiler is the
significant heating equipment.
|
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. Yuanda Boiler
provides various models of industrial steam boiler and hot water
that necessary to the brewery. |
Sugar Mill In sugar mill, steam plays a significant role for the processes of
heating, gelatinization, and saccharify. The temperature needed is
from about 30℃ to 80℃.There is a heating equipment under the mash
kettle, steam enter into the heating equipment and then heat the
raw material in mash kettle. Steam boiler is used for heating,
gelatinization, and saccharify, etc. Heating equipment is equipped
under mash kettle, and then steam produced by boiler enter into the
heating equipment, and then heat the raw materials for starch
hydrolysis.
|
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. Yuanda 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.
|
Textile Industry Industrial boiler plays a significant role in the textile industry,
the steam boiler is used for different processes, such as dyeing
and drying, and support the use of resing finishing stenter, dyeing
machine, drying room, and mixing mill, etc. The needed temperature
of textile process is 60~180℃.
Yuanda boiler developed a wide range of industrial boilers that
could be used for textile industry. During the process of dyeing
and drying in textile industry, steam plays an significant role,
the industrial boilers is used combined with resing finishing
stenter, dyeing machine, drying room and mixing mill. The
temperature range is 60~180℃, thermal oil boiler is available for
textile industry, which achieves high working temperature
(<330℃) under low working pressure (<10 bar). Except hot oil
boiler, oil gas fired steam boiler and biomass water tube steam
boiler is also suitable for textile factories.
|
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. |
Wood Processing Industry In wood industry (plywood mill, carboard factory, fiberboard,
etc.), steam is significant for the processes of preservation,
drying, digestion, and hot processing. While, the hot oil also
could be used as the heat transfer medium instead of stem. Thermal
oil heater is a kind of energy saving boiler with high working
temperature (320℃) and low working pressure (0.8Mpa). Within recent
years, thermal oil heater is very popular in wood industry.
