Compare biomass fuel with coal as well as gas<br>
Contrast biomass fuel with coal

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



The calorific value of biomass pellets is 10% less than tool coal. However biomass pellets can burn out, while coals have 10-15% flammable component left in the coal slag. So in real use, their calorific value are the same.


Biomass pellets are simpler to spark than coals, which can shorten the starting time mainly.

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

Coal's pollutant emission and also rust to the boiler is even more serious than biomass pellets. Coal smoke contains a lot of particle carbons, poisonous SO2, carbon monoxide as well as other corrosion gas Biomass pellets is mostly composed of C-H organic matters, the gas emission is primarily C-H unpredictable gas, with little SO2 or carbon monoxide emission. Biomass fuel is know as tidy fuel. It can considerably reduce the air pollution and carbon emission.

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



Compare biomass pellets as well as natural gas.

Cost of biomass pellets as well as natural gas in boilers

Allow's take a 1 lot boiler as an example. Expect it require 600,000 calories for 1 hour. I exercise the called for quantity of natural gas and also biomass pellets. By increasing their system cost, we can exercise the total cost As the form show, biomass pellets cost much less than gas.



Kcal/kg pricerequired quantitytotal cost.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable source, like coal as well as oil. Biomass energy is the chemical form of solar energy. It includes wood, forestry waste, crop waste, marine plant, pet dung, plant wastes. wood pellet mill machine , the biomass produced by photosynthesis depends on 173 billion load, equal to 10-20 times the yearly international power consumption, yet only 3% of them are utilized. As long as there is sunlight, the biomass energy will certainly never ever go out.



In some backwoods, natural gas is not readily available. At the same time, with even more manufacturing facilities change coal-fired central heating boilers right into gas boiler, the price of natural gas is mosting likely to rise. By contrast, biomass energy is rich in rural areas. bio pellet machine are simple to acquire and process, which don't take much price.



The ash deposits of wood pellets after shedding has minerals as well as carbon. It can be utilized as fertilizer on ranch as well as in yard. You can accumulate the ash deposits from biomass boilers for future use.



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

Under the atmosphere security pressure, coal boilers are restricted in lots of cities. Lots of manufacturing facilities have switched to biomass boiler or gas central heating boiler. Here I want to compare the 3 central heating boilers and identify which is the very best.



First financial investment.

In regard to the boilers with the same capability, gas boilers call for the greatest expense, then comes biomass central heating boiler, as well as coal boiler for the last.



Procedure expense.

In regards to procedure cost, gas boiler > coal central heating boiler > biomass boiler. The gas price differs in various areas, more than biomass and also coal. richi machinery of biomass and coal are comparable, however as coal boilers have reduced effectiveness, the operation price is greater than biomass boiler.



Setting result.

In regards to environmental management, gas boiler > biomass central heating boiler > coal boiler. Gas central heating boilers embrace gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal central heating boilers create the highest possible air pollution, including SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It just produce C, H unstable gases, and little ash deposits.



Application area.

Coal boilers have been restricted in lots of cities, or need to be outfitted with desulfurizer. Gas supply is not uniform in various areas. Some regions don't have natural gas offered, so biomass central heating boilers become their ideal selection.




To conclude, to satisfy the atmosphere demand, gas central heating boilers and biomass central heating boilers are feasible. Gas central heating boilers have the least exhaust, yet the price is the highest. Biomass central heating boilers have inexpensive and also wide application, and the contamination discharge is low. So it has actually been preferred in many locations.
