Contrast biomass fuel with coal


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



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

Biomass pellets are simpler to spark than coals, which can shorten the starting time largely.

The solid discharge of biomass pellets is lower than coal. It can reduce the slag discharge cost and air pollution. The solid discharge of biomass pellets are virtually ash, making up 0.4% ~ 7.0% of the total weight, while the solid emission of coal are ash, alkali, and residual coal, representing 25% -40% of the overall weight.

Coal's toxin emission and also rust to the central heating boiler is even more serious than biomass pellets. Coal smoke includes a great deal of particle carbons, toxic SO2, carbon monoxide and also various other rust gas Biomass pellets is primarily composed of C-H organic matters, the gas emission is mainly C-H volatile gas, with little SO2 or carbon monoxide exhaust. poultry manure pellet machine is referred to as tidy fuel. It can significantly reduce the air pollution and also carbon discharge.

Adoption of biomass fuel in central heating boilers can conserve time and cost than coals. diy pellet press can conserve 10% fuel expense as well as 16% time with biomass pellets than coal.



Contrast biomass pellets and also gas.

Expense of biomass pellets as well as natural gas in central heating boilers

Let's take a 1 lot boiler for instance. Mean it need 600,000 calories for 1 hour. I work out the required amount of natural gas and biomass pellets. By multiplying their unit price, we can work out the complete expense As the kind show, biomass pellets set you back a lot less than natural gas.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable resource, like coal and also oil. Biomass energy is the chemical kind of solar energy. It includes timber, forestry waste, crop waste, aquatic plant, animal dung, plant wastes. Each year, the biomass created by photosynthesis depends on 173 billion lot, equal to 10-20 times the annual global power usage, however just 3% of them are utilized. As long as there is sunlight, the biomass energy will never go out.



In some rural areas, natural gas is not offered. At the same time, with more manufacturing facilities change coal-fired boilers right into gas boiler, the rate of gas is going to rise up. By comparison, biomass power is rich in rural areas. They are very easy to obtain as well as process, which do not take much expense.



The ash residues of timber pellets after burning has minerals and carbon. It can be used as fertilizer on farm as well as in yard. You can accumulate the ash residues from biomass central heating boilers for future usage.



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

Under the setting defense pressure, coal boilers are limited in many cities. Several factories have switched over to biomass boiler or gas central heating boiler. Here I 'd like to compare the 3 boilers as well as figure out which is the best.



First investment.

In term of the central heating boilers with the exact same ability, gas central heating boilers need the greatest cost, after that comes biomass central heating boiler, and also coal boiler for the last.



Procedure expense.

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



Environment effect.

In terms of environmental protection, gas central heating boiler > biomass central heating boiler > coal central heating boiler. Gas boilers embrace gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal central heating boilers generate the greatest contamination, including SO2, CARBON MONOXIDE, ash, alkali, and so on. Biomass central heating boilers arere environmental-friendly than coals. It only generate C, H volatile gases, and also little ash residues.



Application area.

Coal central heating boilers have actually been restricted 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 available, so biomass central heating boilers become their finest choice.




In conclusion, to fulfill the setting need, gas central heating boilers as well as biomass central heating boilers are practical. Gas central heating boilers have the least emission, yet the cost is the highest possible. Biomass boilers have affordable and also wide application, and also the pollution discharge is low. So it has actually been preferred in lots of areas.
