Compare biomass fuel with coal as well as gas<br>
Contrast biomass fuel with coal

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



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

Biomass pellets are simpler to fire up than coals, which can shorten the starting time mostly.

The strong discharge of biomass pellets is lower than coal. It can minimize the slag discharge charge and also air contamination. The strong exhaust of biomass pellets are practically ash, accounting for 0.4% ~ 7.0% of the complete weight, while the solid discharge of coal are ash, alkali, as well as residual coal, accounting for 25% -40% of the complete weight.

Coal's toxin emission and also deterioration to the boiler is much more major than biomass pellets. Coal smoke has a lot of fragment carbons, poisonous SO2, CO as well as other deterioration gas Biomass pellets is mostly made up of C-H raw materials, the gas exhaust is generally C-H volatile gas, with little SO2 or carbon monoxide emission. Biomass fuel is referred to as clean fuel. It can greatly reduce the air pollution as well as carbon emission.

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



Compare biomass pellets and also natural gas.

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

Let's take a 1 lot boiler for example. Mean it need 600,000 calories for 1 hour. I exercise the needed amount of gas and biomass pellets. By increasing their device cost, we can exercise the overall cost As the type show, biomass pellets set you back much less than natural gas.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable source, like coal and also oil. Biomass energy is the chemical kind of solar power. It includes timber, forestry waste, crop waste, aquatic plant, animal dung, plant wastes. Yearly, the biomass created by photosynthesis depends on 173 billion ton, equal to 10-20 times the annual worldwide energy intake, however just 3% of them are made use of. 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 central heating boilers right into gas boiler, the rate of natural gas is mosting likely to rise. By comparison, biomass energy is rich in backwoods. They are very easy to acquire and process, which do not take much cost.



The ash deposits of timber pellets after melting contains minerals and carbon. animal pellet machine can be used as fertilizer on farm and in yard. You can gather the ash deposits from biomass central heating boilers for future use.



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

Under the atmosphere security stress, coal boilers are limited in several cities. Many factories have switched over to biomass central heating boiler or gas central heating boiler. Below I wish to contrast the 3 boilers and also determine which is the most effective.



Preliminary financial investment.

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



Operation price.

In terms of procedure cost, gas boiler > coal central heating boiler > biomass boiler. The gas rate differs in different areas, greater than biomass as well as coal. The rate of biomass and also coal are similar, but as coal boilers have reduced efficiency, the procedure expense is higher than biomass boiler.



Atmosphere impact.

In terms of environmental protection, gas central heating boiler > biomass central heating boiler > coal central heating boiler. Gas central heating boilers embrace gas as fuel, biomass central heating boilers adopt biomass pellets or briquettes. Coal boilers produce the highest pollution, consisting of SO2, CARBON MONOXIDE, ash, antacids, and so on. Biomass boilers arere environmental-friendly than coals. It only produce C, H volatile gases, and also little ash residues.





Application area.

Coal boilers have actually been restricted in numerous cities, or require to be furnished with desulfurizer. Natural gas supply is not uniform in various locations. straw pellet machine do not have natural gas readily available, so biomass boilers become their finest selection.



Finally, to satisfy the setting requirement, gas boilers and also biomass boilers are practical. Gas boilers have the least emission, but the cost is the greatest. Biomass boilers have affordable as well as large application, and the pollution exhaust is low. So it has actually been prominent in numerous locations.
