Compare biomass fuel with coal

The burning performance of biomass fuel is comparable with tool coal, however it have such advantages over coal:



The calorific worth of biomass pellets is 10% less than medium coal. But biomass pellets can wear out, while coals have 10-15% flammable element left in the coal slag. So in real use, their calorific worth coincide.

Biomass pellets are easier to stir up than coals, which can reduce the starting time largely.

The strong discharge of biomass pellets is less than coal. It can reduce the slag discharge fee as well as air pollution. The strong exhaust of biomass pellets are nearly ash, making up 0.4% ~ 7.0% of the total weight, while the strong exhaust of coal are ash, alkali, and also recurring coal, representing 25% -40% of the complete weight.

Coal's toxin exhaust and rust to the central heating boiler is far more severe than biomass pellets. Coal smoke contains a lot of bit carbons, hazardous SO2, carbon monoxide as well as other rust gas Biomass pellets is mostly made up of C-H raw materials, the gas discharge is mainly C-H unpredictable gas, with little SO2 or carbon monoxide emission. Biomass fuel is referred to as clean fuel. It can significantly reduce the air contamination and also carbon discharge.

Fostering of biomass fuel in boilers can conserve time and also expense than coals. A 0.5 t central heating boiler can save 10% fuel cost as well as 16% time with biomass pellets than coal.



Compare biomass pellets and also gas.

Price of biomass pellets and also natural gas in central heating boilers

Let's take a 1 bunch boiler for instance. Suppose it need 600,000 calories for 1 hr. I exercise the called for quantity of natural gas and biomass pellets. By increasing their unit price, we can work out the complete expense As the form show, biomass pellets cost much lower than gas.



Kcal/kg pricerequired quantitytotal price.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.


biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable resource, like coal and also oil. Biomass power is the chemical type of solar power. It consists of timber, forestry waste, plant waste, aquatic plant, pet dung, plant wastes. Each year, the biomass created by photosynthesis depends on 173 billion ton, equal to 10-20 times the annual international power usage, yet only 3% of them are utilized. As long as there is sunlight, the biomass power will never go out.



In some backwoods, gas is not offered. Meanwhile, with more manufacturing facilities transform coal-fired central heating boilers right into natural gas central heating boiler, the cost of natural gas is mosting likely to rise up. By comparison, biomass power is rich in rural areas. They are simple to get and also refine, which do not take much cost.



The ash deposits of wood pellets after burning contains minerals and also carbon. It can be made use of as plant food on ranch and in yard. You can gather the ash residues from biomass central heating boilers for future use.



Comparison of biomass central heating boiler, gas central heating boiler, and also coal central heating boiler.

Under the setting protection pressure, coal boilers are limited in many cities. Lots of manufacturing facilities have switched to biomass central heating boiler or gas boiler. Right here I want to compare the 3 boilers and also identify which is the best.



Preliminary investment.

In term of the central heating boilers with the exact same capacity, gas boilers need the highest possible cost, after that comes biomass central heating boiler, as well as coal central heating boiler for the last.



Operation expense.

In terms of procedure cost, gas boiler > coal central heating boiler > biomass boiler. The gas rate varies in different areas, higher than biomass as well as coal. The price of biomass as well as coal are similar, however as coal central heating boilers have lower efficiency, the procedure cost is greater than biomass boiler.



Atmosphere result.

In terms of environmental protection, gas boiler > biomass boiler > coal boiler. Gas boilers adopt gas as fuel, biomass central heating boilers embrace biomass pellets or briquettes. Coal central heating boilers create the highest contamination, including SO2, CARBON MONOXIDE, ash, alkali, and so on. Biomass central heating boilers arere environmental-friendly than coals. hydraulic pellet press create C, H volatile gases, as well as little ash deposits.



Application location.

Coal boilers have been limited in several cities, or require to be outfitted with desulfurizer. Natural gas supply is not uniform in different areas. Some regions do not have gas offered, so biomass boilers become their best selection.



To conclude, to fulfill the atmosphere requirement, gas central heating boilers as well as biomass central heating boilers are viable. Gas boilers have the least emission, yet the cost is the highest. look what i found have inexpensive and broad application, as well as the pollution exhaust is low. So it has been preferred in numerous locations.
