Biogas Plant Glass Fused Steel Tanks High Performance 6.0 Mohs Hardness
Glass Lined Steel Tank Used As Continuously Stirred Tank Reactor (Cstr) In Biogas Plant
The CSTR is a conventional digester design consisting of an above-ground tank with a fixed pitched roof. Biogas is collected at the top of the tank and is pumped to a separate gas holder. Digestate is removed from the base of the digester tank.
Center Enamel Biogas CSTR tanks are manufactured from glass fused steel and are insulated externally with 100mm of polyrthene board and protected with plastic-coated steel panels. There is no mechanical equipment within the digester tank.
Why use glass lined steel tank other than others ?
Think about these advantages :
* superior performance in corrosion resistance and against rust
* factory fabrication tank . No painting or spray on erection site .
* minimal maintenance cost
* No need crane or other large equipment during erection
* not subjected to severe weather and environment.
* can be designed to future expansion, dismantle or re-movement.
* free service for technical drawings
* turn key service from proposal to tank commissioning .

Glass Lined Steel Digesters And Reactors For Various Environmental Industrial
Center Enamel’s glass lined steel tank is designed to service a wide range of applications like water treatment , municipal and industrial waste water treatment , land filling plant, biogas plant , fire and rescue system , dairy effluent treatment, sewage and slurry treatment , ect. Center Enamel Co. Ltd delivers tailored tank proposals which are suitable for all types of storage or digester system.
Glass lined steel tanks represent the very latest developments in steel tank coating technology. This has provided significant engineering and cost benefits to users across a range of applications since the early 2000s.
The benefits of glass lined steel tanks against more traditional tank coatings include higher durability to impact, lower cost manufacturing, lower carbon footprint and more efficient design principles.
The glass lining is coated to steel plates in high temperature furnace i.e. Spraying and firing process. Before the spraying and firing process , the plates are properly pre-treatment : CNC cutting , shot-blasting , curving , ect . it forms very strong adhesion strength between the coating and the steel plate. The protective coat can prevent corrosion, can withstand strong acid and alkali. It is superior in corrosion resistant .
