Compare biomass fuel with coal and 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 tool coal. However biomass pellets can burn out, while coals have 10-15% combustible component left in the coal slag. So in real usage, their calorific worth coincide.

Biomass pellets are much easier to spark than coals, which can shorten the starting time mostly.

The solid discharge of biomass pellets is less than coal. It can minimize the slag discharge cost as well as air pollution. The solid emission of biomass pellets are almost ash, accounting for 0.4% ~ 7.0% of the complete weight, while the solid emission of coal are ash, alkali, and also recurring coal, accounting for 25% -40% of the total weight.

Coal's pollutant exhaust and also corrosion to the boiler is much more severe than biomass pellets. Coal smoke has a lot of particle carbons, harmful SO2, CO and also various other deterioration gas Biomass pellets is mainly composed of C-H raw materials, the gas emission is mainly C-H unpredictable gas, with little SO2 or CO exhaust. Biomass fuel is know as clean fuel. It can substantially minimize the air pollution and also carbon discharge.

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



Compare biomass pellets as well as natural gas.

Expense of biomass pellets and also natural gas in boilers


Let's take a 1 load boiler as an example. Suppose it need 600,000 calories for 1 hr. I exercise the required amount of gas and also biomass pellets. By increasing their system price, we can work out the total price As the form show, biomass pellets cost much less than natural gas.



Kcal/kg pricerequired quantitytotal price.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable resource, like coal and also oil. Biomass energy is the chemical form of solar energy. It includes wood, forestry waste, plant waste, marine plant, pet dung, plant wastes. Yearly, the biomass created by photosynthesis depends on 173 billion bunch, equal to 10-20 times the annual global power usage, but just 3% of them are used. As look at more info as there is sunshine, the biomass energy will never run out.



In some rural areas, gas is not readily available. On the other hand, with even more manufacturing facilities change coal-fired boilers right into gas boiler, the price of gas is mosting likely to rise up. By comparison, biomass energy is abundant in rural areas. They are easy to get as well as refine, which do not take much cost.



The ash residues of wood pellets after burning contains minerals as well as carbon. It can be utilized as fertilizer on ranch and in garden. You can gather the ash residues from biomass central heating boilers for future usage.



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

Under the atmosphere security pressure, coal central heating boilers are limited in lots of cities. Many factories have switched to biomass central heating boiler or gas boiler. Here I wish to compare the 3 boilers and also determine which is the best.



Initial financial investment.

In regard to the boilers with the very same ability, gas boilers need the highest cost, then comes biomass central heating boiler, as well as coal boiler for the last.



Procedure price.

In regards to operation cost, gas central heating boiler > coal central heating boiler > biomass boiler. The gas price differs in various areas, greater than biomass and coal. The price of biomass as well as coal are comparable, yet as coal central heating boilers have lower efficiency, the operation price is more than biomass central heating boiler.



Setting result.

In regards to environmental protection, gas central heating boiler > biomass central heating boiler > coal central heating boiler. Gas boilers adopt natural gas as fuel, biomass boilers adopt biomass pellets or briquettes. Coal central heating boilers generate the greatest contamination, consisting of SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It just produce C, H unstable gases, and little ash deposits.



Application location.

Coal boilers have actually been restricted in lots of cities, or require to be outfitted with desulfurizer. Gas supply is not uniform in various areas. Some areas do not have gas readily available, so biomass central heating boilers become their finest choice.




To conclude, to satisfy the atmosphere demand, gas boilers and also biomass boilers are viable. pop over to this site have the least exhaust, however the cost is the highest possible. Biomass boilers have inexpensive and also vast application, and the contamination discharge is low. So it has actually been popular in lots of areas.
