Biomass combustion in fluidized bed boilers: Potential

Jan 01, 2009 · Fig. 4 shows the superheater tube corrosion at a 100 MW th facility fired with high chlorine (> 1%) biomass with bituminous coal (CFB boiler located in Germany). The biomass share was 6–10% on heat basis and the gas temperature in the superheater region varied between 450–900 °C.

The results show that in the first winter the pipeline goes into production when the water content is more than 150 mg/kg the hydrate formation risk exists in the pipeline. Hydrate accumulates mainly in the ascending part of the low-lying pipe section, and the greater the height difference of the pipe section, the more hydrate accumulation.

WSSC Water is Winter Ready | WSSC Water

Water is introduced into the hydronic system in one way, flowing down the piping and out the boiler drain, carrying the air with it. The process of isolating and filling is repeated until the hydronic system is full of water and the air removed. Flushing the hydronic system works in reverse, replacing the old water …

Figure 1 and an inside view of a stuck, low-water cutoff in a boiler. As we enter the heart of winter and turn our attention toward cold weather conditions where freezing water can wreak havoc on commercial and residential property, the threat of catastrophic failure to boilers looms large (as seen in Figure 1).. Although failsafes against significant boiler failures do exist and continue to
