1. Abundant Resource:wide range of biomass resources from agricultural waste, forestry, etc.
2. Convenient:the only renewable energy that can be stored and transported; easy to process and use.
3. Low Emission:biomass combustion is carbon neutral, nearly zero CO2 emission and low SO2 emission.
4. Cost-Effective:biomass fuel is abundant and plants like sugar mill, paper plant can use the by-product biomass waste as fuel; governments supply subsidies for biomass power plants.
1. Thermal Power:Coal based thermal power is the most conventional source of electric power.
2. Hydro Power:large investment cost, has a higher requirement of geographical environment, and the water source cannot be guaranteed.
3. Nuclear Power:Nuclear leakage may causes nuclear radiation, and the equipment costs and other costs are much higher than the thermal power;
4. Wind Power:occupy a larger land area, wind speed is instability, wind energy conversion efficiency is low, high cost, equipment is immaturity, etc.
5. Natural Gas Power: higher cost and natural gas shortage
Biomass power is poised to occupy a significant share in the global renewable energy and solid biomass is increasingly being used for electricity production, either in dedicated biomass power plants or co-fired in coal power plants to reduce CO2 emissions. US DOE pre-dicts that by 2025 biomass power generation will dominate among renewable energy sources.
Generating power through the use of biomass represents the cost-effective and cleanest way to provide renewable electricity in biomass potential regions with high levels of biomass resources and its processing activity. Furthermore, use of this resource helps become more energy independent and use of a locally derived fuel provides employment and direct economic benefit to local communities.
The capacity of biomass power generation installed in US has reached 1610 kilo-watts, ranking NO1 in the world. By 2020, the United States is estimated to have a maximum of 7.1 quadrillion Btu of biomass available at prices of $5 per million Btu or lower.
Boiler is a device used to transform the biomass energy into electricity, and it is the core device of power equipment. ZBG’s biomass boiler has a heritage of more than 70 years, and our installed or under construction utility/power plant boilers are making up a bigger and bigger share worldwide.

Supply
01corner tube, self-supporting structure, solving the boiler bulge and support problem.
02full welding membrane water cooling wall structure, good sealing and less heat losses.
03box-type leaving the factory, shorten installation period and strengthen the sealing property of the back-end flue gas dust.
04arrange flag type convection heating surface in front of high temperature superheater, making it long-term stable running under the bad circumstance caused by burning biomass fuel.
05cross-girder grate, with less running resistance, better grate cooling effect, lower breakdown rate and less fuel leakage.
06layer combustion + suspension combustion, higher efficiency
