Contrast biomass fuel with coal

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



The calorific value of biomass pellets is 10% less than medium coal. But biomass pellets can burn out, while coals have 10-15% combustible part left in the coal slag. So in actual use, their calorific value are the same.

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

The strong discharge of biomass pellets is lower than coal. It can decrease the slag discharge charge and also air pollution. The strong exhaust of biomass pellets are almost ash, accounting for 0.4% ~ 7.0% of the total weight, while the strong emission of coal are ash, alkali, as well as recurring coal, accounting for 25% -40% of the total weight.


Coal's contaminant emission and also rust to the boiler is much more major than biomass pellets. Coal smoke contains a great deal of particle carbons, hazardous SO2, CO as well as various other corrosion gas Biomass pellets is primarily made up of C-H raw materials, the gas exhaust is generally C-H volatile gas, with little SO2 or CO emission. Biomass fuel is know as tidy fuel. It can substantially reduce the air pollution as well as carbon discharge.

Fostering of biomass fuel in boilers can save time and cost than coals. small fish feed machine can save 10% fuel cost and also 16% time with biomass pellets than coal.



Compare biomass pellets and natural gas.

Cost of biomass pellets and also gas in central heating boilers

Let's take a 1 heap boiler as an example. Expect it require 600,000 calories for 1 hour. coal pellet making machine exercise the needed quantity of gas and biomass pellets. By increasing their system rate, we can exercise the total price As the form show, biomass pellets cost much less than gas.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable source, like coal as well as oil. Biomass energy is the chemical type of solar energy. It consists of wood, forestry waste, plant waste, water plant, animal dung, plant wastes. Each year, the biomass generated by photosynthesis depends on 173 billion ton, equal to 10-20 times the annual international energy usage, but just 3% of them are used. As long as there is sunlight, the biomass energy will certainly never run out.



In some backwoods, natural gas is not readily available. On the other hand, with even more factories transform coal-fired boilers right into natural gas boiler, the cost of gas is mosting likely to rise up. By comparison, biomass energy 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 and carbon. It can be made use of as plant food on ranch and also in garden. You can collect the ash deposits from biomass boilers for future usage.



Contrast of biomass boiler, gas boiler, and coal boiler.

Under the atmosphere defense stress, coal central heating boilers are limited in lots of cities. Numerous factories have switched to biomass boiler or gas boiler. Right here I would love to contrast the 3 boilers as well as determine which is the very best.



Initial financial investment.

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



Procedure price.

In regards to operation price, gas boiler > coal boiler > biomass boiler. The gas cost varies in various locations, higher than biomass and coal. The rate of biomass and also coal are comparable, yet as coal boilers have lower performance, the procedure cost is higher than biomass boiler.



Atmosphere effect.

In terms of environmental management, gas boiler > biomass boiler > coal boiler. Gas central heating boilers adopt gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal central heating boilers produce the greatest contamination, including SO2, CO, ash, antacids, etc. Biomass central heating boilers arere environmental-friendly than coals. It just create C, H unpredictable gases, and little ash deposits.



Application area.

Coal central heating boilers have actually been restricted in several cities, or need to be outfitted with desulfurizer. Natural gas supply is not uniform in different locations. Some regions don't have natural gas available, so biomass boilers become their best selection.



To conclude, to satisfy the atmosphere demand, gas central heating boilers as well as biomass boilers are practical. Gas central heating boilers have the least emission, however the cost is the greatest. Biomass central heating boilers have low cost and broad application, as well as the air pollution exhaust is low. So it has actually been prominent in several locations.
