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

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



The calorific worth of biomass pellets is 10% lower than tool coal. Yet biomass pellets can wear out, while coals have 10-15% flammable component left in the coal slag. So in actual use, their calorific value coincide.

Biomass pellets are less complicated to stir up than coals, which can reduce the starting time greatly.

The solid discharge of biomass pellets is less than coal. It can minimize the slag discharge cost and air pollution. The solid discharge of biomass pellets are practically ash, making up 0.4% ~ 7.0% of the complete weight, while the strong discharge of coal are ash, antacids, and also recurring coal, making up 25% -40% of the complete weight.

Coal's toxin exhaust and rust to the central heating boiler is even more severe than biomass pellets. Coal smoke consists of a great deal of fragment carbons, toxic SO2, CO and various other corrosion gas Biomass pellets is mostly made up of C-H raw materials, the gas discharge is mainly C-H volatile gas, with little SO2 or CO emission. Biomass fuel is called tidy fuel. It can considerably decrease the air pollution as well as 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 and also 16% time with biomass pellets than coal.



Compare biomass pellets and natural gas.

Expense of biomass pellets as well as gas in central heating boilers


Allow's take a 1 ton boiler for example. Expect it need 600,000 calories for 1 hour. I exercise the required quantity of gas and biomass pellets. By increasing their unit rate, we can exercise the total price As the type show, biomass pellets cost much less than gas.



Kcal/kg pricerequired quantitytotal expense.

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 type of solar power. It includes wood, forestry waste, crop waste, marine plant, animal dung, plant wastes. Yearly, the biomass generated by photosynthesis depends on 173 billion load, equal to 10-20 times the yearly international power intake, but just 3% of them are made use of. As long as there is sunshine, the biomass power will certainly never go out.



In some backwoods, natural gas is not available. Meanwhile, with even more manufacturing facilities change coal-fired central heating boilers into gas boiler, the rate of gas is going to rise up. By contrast, biomass power is abundant in backwoods. They are easy to get as well as process, which don't take much price.



The ash deposits of wood pellets after melting consists of minerals as well as carbon. It can be utilized as plant food on farm and in garden. You can collect the ash residues from biomass boilers for future usage.



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

Under the setting protection stress, coal central heating boilers are limited in many cities. Numerous factories have actually switched to biomass boiler or gas central heating boiler. Right here I would love to contrast the 3 boilers and also figure out which is the very best.




Initial financial investment.

In regard to the boilers with the same capability, gas central heating boilers require the highest expense, after that comes biomass boiler, and also coal central heating boiler for the last.



Operation price.

In terms of procedure expense, gas boiler > coal boiler > biomass boiler. The gas rate differs in different areas, higher than biomass and also coal. The cost of biomass and coal are similar, yet as coal central heating boilers have reduced effectiveness, the procedure expense is more than biomass central heating boiler.



Atmosphere effect.

In regards to environmental management, gas central heating boiler > biomass boiler > coal boiler. Gas boilers adopt natural gas as fuel, biomass boilers take on biomass pellets or briquettes. chicken manure pelletizer create the greatest contamination, consisting of SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It only produce C, H unstable gases, as well as little ash deposits.



Application area.

Coal boilers have been limited in several cities, or require to be equipped with desulfurizer. Natural gas supply is not uniform in various areas. pellet extruder 3d don't have natural gas available, so biomass central heating boilers become their finest selection.



To conclude, to fulfill the environment requirement, gas central heating boilers and also biomass central heating boilers are feasible. Gas central heating boilers have the least exhaust, but the expense is the greatest. Biomass boilers have low cost as well as broad application, as well as the pollution exhaust is low. So it has been prominent in numerous locations.
