Research on the Gas Reburning in a Circulating

2012-6-12·N2O emissions from coal fired fluidized-bed combustion are approximately 30360 mg/Nm3, much higher than that from pulverized coal combustion (less than 30 mg/Nm3). One approach to reduce the N2O is to reburn the biomass gasification gas in the coal-fired fluidized bed. In this paper, the effects of gasified biomass reburning on the integrated boiler system were investigated by both

CFB boiler bed temperature's improved fuzzy control

Keeping the regular bed temperature is the key point of making the circulating fluidized bed boiler work stably. The difficult part of the CFB bed temperature control system lies in: there are many influence factors, little tunable factors, large time delay, big inertia and strong coupling between bed temperature and the main steam pressure.

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
