With abundant biomass resource, the biomass fired boiler, as the alternatives of the coal fired boiler, enjoys a great popularity in the current international and domestic market.as biomass fuel, the straw, the residue of agrotechny as well as the forestry residue equals 0.4 billion ton coal. According to statics, the total amount of the 65 ton boiler is about 460,000 sets,of which output is 4.3million ton/hour. If these are replaced by biomass fuel,or even 2% of them, the utilization rate of the biomass fuel is over 5000ton. Currently, the annual utilization rate is about 8milliom ton. The rate is much higher in developed areas.
The biomass fired boiler is an eco-friendly and low caborn energy-produced boiler. Its fuel is produced from agricultural residue and it is very clean.
otherwise, the characters of biomass fired boiler are listed as follows:
1. The technology is matured, the manufacturing fuel is simple to produce,the specialized boiler is chain grate boiler or CFB boiler.
2. the biomass boiler will produce less pollutant . The So2 concentration discharged from boiler is much lower than gas, after a dedusting facilities is installed, the blowdown of gas fire will reach the gas fired standard.
3. Economy. When gas price will exceed 3.5yuan per cube. Biomass boiler will reveal its cost advantage, especially in the industrial supply heating. A ton of steam
produced by biomass boiler is 100yuan cheaper than that produced by gas fired boiler.
Distributed heat supplying. This kind of boiler has good distribution layer, flexible operation and good adaptability,which an meet the multiple heat needs.
