Compare biomass fuel with coal

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



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

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

The solid discharge of biomass pellets is lower than coal. wood pelletizer can lower the slag discharge cost and air contamination. The solid discharge of biomass pellets are virtually ash, accounting for 0.4% ~ 7.0% of the total weight, while the strong exhaust of coal are ash, antacids, as well as residual coal, representing 25% -40% of the complete weight.

Coal's contaminant discharge and rust to the boiler is much more significant than biomass pellets. Coal smoke has a lot of fragment carbons, harmful SO2, carbon monoxide as well as other deterioration gas Biomass pellets is mostly made up of C-H raw materials, the gas exhaust is primarily C-H unpredictable gas, with little SO2 or CO exhaust. Biomass fuel is know as clean fuel. poultry feed machine can greatly lower the air pollution and also carbon emission.

Adoption of biomass fuel in boilers can conserve time and price than coals. A 0.5 t boiler can conserve 10% fuel cost as well as 16% time with biomass pellets than coal.



Compare biomass pellets as well as gas.

Expense of biomass pellets as well as natural gas in boilers

Allow's take a 1 heap boiler for instance. Intend it need 600,000 calories for 1 hr. I exercise the called for amount of gas and also biomass pellets. By increasing their device rate, we can work out the complete expense As the form show, biomass pellets cost a lot lower than natural gas.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

Gas is a non-renewable resource, like coal and also oil. Biomass power is the chemical form of solar power. It consists of wood, forestry waste, crop waste, aquatic plant, pet dung, plant wastes. Every year, the biomass generated by photosynthesis is up to 173 billion heap, equal to 10-20 times the yearly global power intake, however only 3% of them are used. As long as there is sunlight, the biomass energy will certainly never ever go out.



In some rural areas, natural gas is not readily available. At the same time, with even more factories transform coal-fired boilers right into natural gas central heating boiler, the cost of natural gas is mosting likely to rise. By comparison, biomass energy is abundant in backwoods. They are easy to obtain and refine, which don't take much cost.



The ash deposits of timber pellets after burning contains minerals and also carbon. It can be made use of as plant food on ranch as well as in garden. You can accumulate the ash residues from biomass boilers for future usage.



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

Under the environment security pressure, coal central heating boilers are limited in lots of cities. Several manufacturing facilities have changed to biomass boiler or gas boiler. Right here I would love to contrast the 3 boilers and also identify which is the very best.



First financial investment.

In regard to the central heating boilers with the very same capacity, gas boilers need the greatest expense, after that comes biomass central heating boiler, and coal boiler for the last.



Operation cost.

In regards to operation expense, gas boiler > coal boiler > biomass central heating boiler. The gas price varies in various locations, greater than biomass as well as coal. The cost of biomass as well as coal are similar, yet as coal central heating boilers have lower effectiveness, the procedure expense is more than biomass central heating boiler.



Setting impact.

In terms of environmental management, gas central heating boiler > biomass boiler > coal boiler. Gas central heating boilers adopt natural gas as fuel, biomass central heating boilers embrace biomass pellets or briquettes. Coal boilers generate the highest contamination, including SO2, CO, ash, alkali, etc. Biomass central heating boilers arere environmental-friendly than coals. It just produce C, H unpredictable gases, as well as little ash deposits.



Application area.

Coal boilers have been limited in many cities, or require to be outfitted with desulfurizer. Natural gas supply is not uniform in various areas. Some areas don't have natural gas offered, so biomass central heating boilers become their ideal selection.



In conclusion, to fulfill the environment requirement, gas central heating boilers and biomass central heating boilers are practical. Gas central heating boilers have the least emission, but the expense is the highest. Biomass central heating boilers have inexpensive as well as wide application, as well as the contamination emission is low. So it has actually been prominent in numerous areas.
