Compare biomass fuel with coal and also gas<br>
Contrast biomass fuel with coal

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



The calorific worth of biomass pellets is 10% lower than medium coal. But biomass pellets can burn out, while coals have 10-15% flammable component left in the coal slag. So in real usage, their calorific value are the same.

Biomass pellets are simpler to ignite than coals, which can shorten the starting time mostly.

The strong discharge of biomass pellets is less than coal. It can lower the slag discharge charge and air pollution. The strong emission of biomass pellets are almost ash, representing 0.4% ~ 7.0% of the total weight, while the strong discharge of coal are ash, antacids, and also residual coal, representing 25% -40% of the overall weight.

Coal's pollutant emission as well as rust to the central heating boiler is even more severe than biomass pellets. Coal smoke contains a lot of fragment carbons, harmful SO2, CO and also other rust gas Biomass pellets is mostly composed of C-H raw materials, the gas emission is primarily C-H unstable gas, with little SO2 or carbon monoxide emission. Biomass fuel is called clean fuel. It can substantially reduce the air contamination and also carbon emission.

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



Contrast biomass pellets and also gas.

Price of biomass pellets as well as natural gas in central heating boilers

Allow's take a 1 heap central heating boiler for example. Suppose it need 600,000 calories for 1 hour. I exercise the required amount of natural gas and also biomass pellets. By multiplying their device rate, we can exercise the complete expense As the kind show, biomass pellets set you back much lower than natural gas.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

Gas is a non-renewable source, like coal as well as oil. Biomass energy is the chemical kind of solar energy. It includes wood, forestry waste, plant waste, aquatic plant, pet dung, plant wastes. Annually, feed pellet mill for sale produced by photosynthesis depends on 173 billion lot, equal to 10-20 times the annual worldwide power intake, yet only 3% of them are made use of. As long as there is sunlight, the biomass power will never ever run out.



In some rural areas, gas is not readily available. Meanwhile, with even more manufacturing facilities transform coal-fired central heating boilers right into natural gas boiler, the price of gas is mosting likely to rise. By comparison, biomass power is abundant in rural areas. They are easy to obtain and refine, which do not take much price.



The ash deposits of timber pellets after burning includes minerals and also carbon. It can be used as fertilizer on ranch as well as in garden. You can collect the ash residues from biomass central heating boilers for future usage.




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

Under the environment protection pressure, coal boilers are limited in several cities. Numerous factories have changed to biomass boiler or gas boiler. hop over to this site would love to compare the 3 central heating boilers as well as figure out which is the best.



Preliminary investment.

In term of the boilers with the very same capability, gas central heating boilers call for the greatest cost, after that comes biomass boiler, and also coal boiler for the last.



Procedure price.

In terms of operation cost, gas central heating boiler > coal central heating boiler > biomass boiler. The gas rate differs in different locations, more than biomass as well as coal. The cost of biomass as well as coal are similar, however as coal boilers have lower efficiency, the operation cost is greater than biomass central heating boiler.



Environment impact.

In terms of environmental management, gas boiler > biomass central heating boiler > coal central heating boiler. Gas boilers take on natural gas as fuel, biomass central heating boilers adopt biomass pellets or briquettes. Coal boilers produce the highest pollution, including SO2, CO, ash, alkali, etc. Biomass central heating boilers arere environmental-friendly than coals. It just generate C, H volatile gases, and also little ash residues.




Application location.

Coal central heating boilers have actually been restricted in several cities, or need to be furnished with desulfurizer. Gas supply is not uniform in different locations. Some regions don't have natural gas offered, so biomass central heating boilers become their ideal choice.



To conclude, to satisfy the atmosphere need, gas boilers and biomass boilers are sensible. Gas boilers have the least emission, but the price is the greatest. Biomass central heating boilers have low cost and vast application, and the pollution discharge is low. So it has actually been prominent in numerous areas.
