How Sitong Coal Fired CFB Boiler Anti-Wear

Date:2016-04-21share us:

Abrasion might occur and affect the boiler efficiency, then what we can do to realize anti-wear during coal fired circulating fluidized bed boiler operating? New technology is used in circulating fluidized bed boilers manufactured by Sitong.

1.Superheater and economizer.

High temperature separator is set in front of the superheater and economizer to largely reduce the inlet flue gas density and refine the particle size. This can reduce the fly ash particle in washing and wearing superheater and economizer. 

2.Submerged tubes

The lowest place for submerged tubes should be 450mm, and the flue gas speed should no high than 5.5m/s. The tubes adopt stainless steel anti-wear fins and its service life is long. For instance, if we use 4000Kcal/kg bituminous coal in the CFB boiler, the submerged tube life can be 4 years or longer.

3.Boiler furnace, separator

All the separator inlet, separator wall, separator outlet, and return feed device use corundum wear castable or plastic material. Due to high quality materials and reasonable design, the coal fired CFB boiler manufactured by Sitong Boiler is anti-wear and have long service life.

Circulating fluidized bed boiler can burn various fuels, such as lignite coal, bituminous coal, anthracite coal, furnace slag, MSW, biomass, etc. And this kind of boiler is efficient and environmental.
