Contrast biomass fuel with coal

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



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

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

The solid discharge of biomass pellets is lower than coal. It can decrease the slag discharge charge and also air pollution. The strong discharge of biomass pellets are nearly ash, accounting for 0.4% ~ 7.0% of the complete weight, while the strong discharge of coal are ash, antacids, as well as recurring coal, representing 25% -40% of the complete weight.

Coal's contaminant emission and also deterioration to the central heating boiler is far more severe than biomass pellets. Coal smoke includes a lot of fragment carbons, poisonous SO2, CO and also other corrosion gas Biomass pellets is primarily made up of C-H raw materials, the gas discharge is generally C-H volatile gas, with little SO2 or CO emission. Biomass fuel is know as clean fuel. It can significantly decrease the air contamination as well as carbon exhaust.

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



Contrast biomass pellets and also natural gas.

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

Let's take a 1 bunch central heating boiler as an example. Mean it need 600,000 calories for 1 hour. I work out the required amount of natural gas and also biomass pellets. By multiplying their unit rate, we can exercise the total expense As the kind show, biomass pellets cost a lot lower than natural gas.



Kcal/kg pricerequired quantitytotal cost.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.


biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable source, like coal and oil. Biomass power is the chemical kind of solar power. It consists of wood, forestry waste, crop waste, marine plant, pet dung, plant wastes. Every year, the biomass created by photosynthesis depends on 173 billion load, equal to 10-20 times the annual international power consumption, but just 3% of them are used. As long as there is sunshine, the biomass power will certainly never go out.



In some rural areas, natural gas is not available. On the other hand, with more factories change coal-fired central heating boilers right into gas central heating boiler, the cost of gas is going to rise. By contrast, biomass power is rich in rural areas. They are simple to get and refine, which don't take much cost.




The ash residues of wood pellets after melting consists of minerals as well as carbon. It can be made use of as plant food on ranch and in garden. floating fish feed pellet machine can accumulate the ash deposits from biomass boilers for future usage.



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

Under the setting defense stress, coal boilers are limited in numerous cities. Numerous factories have actually switched to biomass central heating boiler or gas boiler. Right here I wish to compare the 3 boilers and identify which is the most effective.



Initial investment.

In term of the boilers with the same capacity, gas central heating boilers call for the greatest price, after that comes biomass central heating boiler, and coal central heating boiler for the last.



Procedure expense.

In terms of operation expense, gas central heating boiler > coal boiler > biomass boiler. The gas rate varies in different areas, more than biomass as well as coal. The rate of biomass as well as coal are similar, but as coal central heating boilers have lower effectiveness, the operation expense is higher than biomass boiler.



Setting result.

In regards to environmental protection, gas boiler > biomass boiler > coal boiler. Gas central heating boilers adopt natural gas as fuel, biomass boilers embrace biomass pellets or briquettes. Coal central heating boilers generate the highest possible contamination, consisting of SO2, CARBON MONOXIDE, ash, alkali, and so on. building a pellet mill -friendly than coals. It only create C, H unstable gases, and little ash deposits.



Application area.

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



Finally, to fulfill the atmosphere need, gas central heating boilers and biomass central heating boilers are viable. Gas central heating boilers have the least emission, however the price is the highest possible. Biomass boilers have affordable and also large application, as well as the air pollution exhaust is reduced. So it has actually been preferred in numerous areas.
