Compare biomass fuel with coal

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



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

Biomass pellets are much easier to ignite than coals, which can reduce the starting time mostly.

The strong discharge of biomass pellets is less than coal. It can decrease the slag discharge charge and air pollution. The solid emission of biomass pellets are almost ash, accounting for 0.4% ~ 7.0% of the total weight, while the solid emission of coal are ash, antacids, and also recurring coal, making up 25% -40% of the complete weight.

Coal's contaminant exhaust and also rust to the central heating boiler is much more severe than biomass pellets. Coal smoke includes a lot of particle carbons, poisonous SO2, CO and various other deterioration gas Biomass pellets is mainly made up of C-H organic matters, the gas exhaust is primarily C-H volatile gas, with little SO2 or CO discharge. Biomass fuel is called tidy fuel. It can significantly decrease the air contamination and also carbon emission.

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



Contrast biomass pellets and natural gas.

Cost of biomass pellets and also gas in central heating boilers

Let's take a 1 ton central heating boiler for example. Intend it need 600,000 calories for 1 hour. I work out the called for amount of natural gas as well as biomass pellets. By multiplying their system price, we can exercise the overall expense As the kind show, biomass pellets set you back a lot less than natural gas.



Kcal/kg pricerequired quantitytotal price.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable source, like coal and also oil. Biomass power is the chemical kind of solar power. It consists of timber, forestry waste, plant waste, marine plant, animal dung, plant wastes. Each year, the biomass created by photosynthesis is up to 173 billion heap, equal to 10-20 times the annual international power consumption, but only 3% of them are utilized. As long as there is sunlight, the biomass power will never run out.



In some backwoods, natural gas is not offered. At the same time, with more manufacturing facilities change coal-fired central heating boilers right into gas central heating boiler, the price of gas is mosting likely to rise up. By comparison, biomass power is rich in rural areas. They are easy to obtain as well as refine, which do not take much price.




The ash deposits of wood pellets after burning has minerals and also carbon. https://joyrulez.com/blogs/164337/Do-you-find-out-about-biomass-pellet-maker can be made use of as fertilizer on farm and also in yard. richi pellet can gather the ash residues from biomass central heating boilers for future use.



Comparison of biomass boiler, gas central heating boiler, as well as coal boiler.

Under the setting defense pressure, coal central heating boilers are restricted in many cities. Several factories have actually switched to biomass boiler or gas boiler. Right here I wish to compare the 3 central heating boilers and figure out which is the very best.



Initial financial investment.

In term of the boilers with the very same capability, gas boilers require the highest possible price, after that comes biomass boiler, and also coal boiler for the last.



Operation cost.

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



Environment impact.


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



Application area.

Coal central heating boilers have been limited in lots of cities, or require to be geared up with desulfurizer. Gas supply is not uniform in different areas. Some areas don't have gas available, so biomass boilers become their finest choice.



In conclusion, to fulfill the environment need, gas central heating boilers as well as biomass boilers are practical. Gas boilers have the least exhaust, however the cost is the highest. Biomass central heating boilers have low cost as well as vast application, as well as the air pollution exhaust is low. So it has actually been preferred in lots of areas.
