Compare biomass fuel with coal

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



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

Biomass pellets are much easier to ignite than coals, which can reduce the starting time greatly.

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

Coal's toxin exhaust and deterioration to the boiler is much more severe than biomass pellets. Coal smoke contains a lot of fragment carbons, toxic SO2, CO as well as other corrosion gas Biomass pellets is primarily composed of C-H raw materials, the gas discharge is primarily C-H unpredictable gas, with little SO2 or carbon monoxide discharge. Biomass fuel is called clean fuel. fish pellet making machine can significantly decrease the air pollution as well as carbon discharge.

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



Compare biomass pellets and also gas.

Price of biomass pellets and also gas in boilers


Let's take a 1 bunch central heating boiler for example. Mean ring die pellet machine need 600,000 calories for 1 hr. I exercise the required quantity of natural gas as well as biomass pellets. By increasing their unit rate, we can exercise the total cost As the kind show, biomass pellets set you back a lot lower than natural gas.

natural 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 form of solar energy. It includes timber, forestry waste, crop waste, water plant, pet dung, plant wastes. Each year, the biomass created by photosynthesis is up to 173 billion load, equal to 10-20 times the yearly global energy intake, but just 3% of them are used. As long as there is sunshine, the biomass power will certainly never ever go out.



In some backwoods, gas is not readily available. Meanwhile, with even more factories transform coal-fired central heating boilers into gas boiler, the rate of natural gas is going to rise up. By contrast, biomass power is abundant in rural areas. They are very easy to acquire and also refine, which do not take much expense.



The ash residues of wood pellets after melting consists of minerals and carbon. It can be made use of as fertilizer on farm and also in yard. You can collect the ash deposits from biomass boilers for future use.



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

Under the atmosphere defense stress, coal boilers are limited in numerous cities. Many factories have actually switched over to biomass boiler or gas central heating boiler. Below I want to compare the 3 boilers as well as find out which is the most effective.



Preliminary financial investment.

In regard to the boilers with the same capability, gas central heating boilers call for the greatest price, then comes biomass central heating boiler, and also coal central heating boiler for the last.



Operation expense.

In regards to operation expense, gas central heating boiler > coal central heating boiler > biomass central heating boiler. The gas price differs in various areas, higher than biomass as well as coal. The rate of biomass and coal are similar, but as coal boilers have reduced efficiency, the procedure cost is more than biomass boiler.



Setting effect.


In terms of environmental protection, gas central heating boiler > biomass boiler > coal boiler. Gas boilers embrace gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal boilers produce the greatest pollution, consisting of SO2, CO, ash, antacids, etc. Biomass boilers arere environmental-friendly than coals. It just produce C, H volatile gases, and little ash residues.



Application area.

Coal boilers have been limited in numerous cities, or need to be furnished with desulfurizer. Gas supply is not uniform in different areas. Some areas don't have gas readily available, so biomass central heating boilers become their finest choice.



To conclude, to fulfill the atmosphere need, gas boilers as well as biomass central heating boilers are sensible. Gas central heating boilers have the least emission, but the expense is the greatest. Biomass boilers have inexpensive as well as broad application, and also the pollution emission is low. So it has been preferred in many areas.
