CFB High fuel flexibility

1. The main advantage of our boiler is its superb fuel flexibility. Most of the over 90 references around the world are multifuel boilers that combust biomasses and fossil fuels in continuously varying proportions.
2. Cocombustion is an environmentally benign method of combining excellent reliability and availability with great potential to optimize operational costs by allowing several fuel alternatives.
CFB Boiler Low environmental impact

1. As for temperatures inside the furnace, while a regular boiler reaches 1,400-1,500°C, temperatures inside a CFB are in the low range of 800-900°C, thus inhibiting the generation of thermal nitrogen oxides (NOx whose production is dependent on combustion temperature).
2. Further, with the use of two-stage combustion, NOx generation can be limited to less than 100 ppm. When limestone is supplied to the furnace, furnace desulfurization can take place as illustrated by the following chemical equations.
Advantage

1. High burning efficiency, good gas and coal particle mixing,the unburned big particles can be recycled to the hearth and be reused efficiently.
2. De-sulfur efficiency is high,and the burning temperature is low,so,the NOX emission is low.
3. The load can be adjusted in a wide range and with a high speed.
4. The pretreatment system is simple(comparing to the coal powder boiler),the coal residue can be synthetically used.
