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

The burning efficiency of biomass fuel is comparable with tool coal, however it have such advantages over coal:



The calorific worth of biomass pellets is 10% less than tool coal. Yet biomass pellets can burn out, while coals have 10-15% flammable part left in the coal slag. So in real usage, their calorific value coincide.

Biomass pellets are simpler to ignite than coals, which can reduce the starting time largely.

The strong discharge of biomass pellets is lower than coal. It can reduce the slag discharge cost as well as air pollution. The strong discharge of biomass pellets are almost ash, making up 0.4% ~ 7.0% of the complete weight, while the strong emission of coal are ash, antacids, and also residual coal, representing 25% -40% of the total weight.

Coal's contaminant exhaust and also rust to the boiler is far more severe than biomass pellets. Coal smoke has a great deal of fragment carbons, toxic SO2, CO as well as other deterioration gas Biomass pellets is primarily composed of C-H raw materials, the gas emission is generally C-H unstable gas, with little SO2 or CO emission. Biomass fuel is called tidy fuel. It can significantly lower the air pollution and carbon emission.

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



Contrast biomass pellets as well as gas.

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

Allow's take a 1 lot boiler for instance. Expect it require 600,000 calories for 1 hour. I exercise the needed amount of gas and biomass pellets. By multiplying their device price, we can work out the overall expense As the form show, biomass pellets cost much lower than gas.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable resource, like coal and oil. Biomass power is the chemical type of solar energy. It consists of wood, forestry waste, plant waste, marine plant, animal dung, plant wastes. Yearly, the biomass produced by photosynthesis is up to 173 billion lot, equal to 10-20 times the annual worldwide power intake, yet just 3% of them are used. As long as there is sunlight, the biomass power will never run out.



In some backwoods, natural gas is not offered. Meanwhile, with more manufacturing facilities change coal-fired boilers right into natural gas boiler, the price of natural gas is going to rise. By comparison, biomass power is rich in backwoods. They are simple to get and also refine, which do not take much expense.



The ash deposits of wood pellets after shedding has minerals and carbon. It can be utilized as fertilizer on farm and also in garden. You can accumulate the ash deposits from biomass boilers for future usage.



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

Under the atmosphere protection stress, coal boilers are restricted in lots of cities. Numerous factories have actually switched over to biomass central heating boiler or gas boiler. Here wood pelletizer equipment want to compare the 3 central heating boilers and figure out which is the very best.



First investment.

In regard to the boilers with the same capability, gas boilers need the highest expense, then comes biomass central heating boiler, and coal central heating boiler for the last.



Procedure expense.


In terms of procedure expense, gas boiler > coal central heating boiler > biomass central heating boiler. The gas rate varies in different locations, greater than biomass and also coal. cpm pellet press of biomass as well as coal are similar, but as coal central heating boilers have lower efficiency, the procedure expense is greater than biomass boiler.



Environment effect.

In terms of environmental management, gas boiler > biomass boiler > coal central heating boiler. Gas central heating boilers take on gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal central heating boilers create the greatest air pollution, including SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It only produce C, H unpredictable gases, as well as little ash residues.



Application location.

Coal central heating boilers have been restricted in several cities, or require to be outfitted with desulfurizer. Natural gas supply is not uniform in different areas. Some areas do not have gas offered, so biomass boilers become their best selection.




Finally, to meet the environment requirement, gas boilers and biomass central heating boilers are viable. Gas central heating boilers have the least discharge, however the cost is the highest. Biomass boilers have affordable as well as broad application, and the contamination emission is reduced. So it has actually been prominent in lots of areas.
