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


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




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

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

The solid discharge of biomass pellets is lower than coal. It can reduce the slag discharge fee as well as air contamination. The strong discharge of biomass pellets are nearly ash, making up 0.4% ~ 7.0% of the overall weight, while the strong discharge of coal are ash, alkali, and also recurring coal, representing 25% -40% of the total weight.

Coal's pollutant discharge and also deterioration to the boiler is even more major than biomass pellets. richi pellet mill has a great deal of bit carbons, poisonous SO2, carbon monoxide as well as various other deterioration gas Biomass pellets is primarily composed of C-H organic matters, the gas emission is generally C-H volatile gas, with little SO2 or carbon monoxide exhaust. Biomass fuel is know as tidy fuel. It can significantly decrease the air pollution and carbon discharge.

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



Contrast biomass pellets and gas.

Cost of biomass pellets and also gas in boilers

Allow's take a 1 load boiler for instance. Intend it require 600,000 calories for 1 hr. I exercise the called for quantity of gas and also biomass pellets. By increasing their device cost, we can work out the complete expense As the kind 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.



Gas is a non-renewable resource, like coal as well as oil. Biomass power is the chemical form of solar energy. It includes wood, forestry waste, plant waste, water plant, pet dung, plant wastes. Each year, the biomass produced by photosynthesis is up to 173 billion bunch, equal to 10-20 times the yearly international power usage, yet only 3% of them are utilized. As long as there is sunshine, the biomass energy will certainly never ever go out.



In some backwoods, natural gas is not available. At the same time, with more factories change coal-fired central heating boilers into natural gas boiler, the rate of natural gas is mosting likely to rise. By contrast, biomass energy is rich in rural areas. They are very easy to acquire and refine, which do not take much price.



The ash deposits of timber pellets after melting includes minerals and carbon. It can be made use of as plant food on farm and also in yard. You can accumulate the ash residues from biomass central heating boilers for future use.



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

Under the atmosphere defense stress, coal boilers are restricted in numerous cities. Many factories have changed to biomass central heating boiler or gas central heating boiler. Right here I would love to compare the 3 central heating boilers and also find out which is the most effective.



Preliminary investment.

In term of the central heating boilers with the exact same capability, gas boilers need the highest possible price, then comes biomass boiler, and coal boiler for the last.



Operation price.

In terms of operation cost, gas central heating boiler > coal central heating boiler > biomass central heating boiler. The gas cost varies in different areas, higher than biomass and also coal. The price of biomass and coal are comparable, yet as coal central heating boilers have reduced efficiency, the operation price is greater than biomass central heating boiler.



Setting impact.

In regards to environmental management, gas boiler > biomass boiler > coal boiler. Gas boilers adopt gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal boilers create the highest possible pollution, including SO2, CO, ash, alkali, and so on. Biomass boilers arere environmental-friendly than coals. It only generate C, H volatile gases, and little ash deposits.



Application location.

Coal boilers have actually been restricted in many cities, or require to be furnished with desulfurizer. Natural gas supply is not uniform in different locations. used animal feed pellet mill for sale don't have natural gas available, so biomass boilers become their finest choice.



In conclusion, to meet the environment demand, gas central heating boilers and also biomass central heating boilers are sensible. Gas central heating boilers have the least exhaust, however the price is the highest possible. Biomass boilers have low cost as well as broad application, as well as the pollution discharge is reduced. So it has been popular in several areas.
