Contrast biomass fuel with coal

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



The calorific worth of biomass pellets is 10% lower than medium coal. However biomass pellets can stress out, while coals have 10-15% combustible component left in the coal slag. So in actual usage, their calorific value coincide.

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

The solid discharge of biomass pellets is lower than coal. It can reduce the slag discharge charge and also air pollution. The solid exhaust of biomass pellets are almost ash, representing 0.4% ~ 7.0% of the total weight, while the solid discharge of coal are ash, antacids, and recurring coal, accounting for 25% -40% of the complete weight.

Coal's pollutant emission as well as deterioration to the central heating boiler is much more serious than biomass pellets. Coal smoke consists of a lot of fragment carbons, hazardous SO2, carbon monoxide and also various other rust gas Biomass pellets is generally composed of C-H raw materials, the gas discharge is primarily C-H unpredictable gas, with little SO2 or CO discharge. Biomass fuel is referred to as tidy fuel. It can substantially lower the air pollution as well as carbon discharge.

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



Compare biomass pellets as well as gas.

Cost of biomass pellets and natural gas in central heating boilers

Let's take a 1 bunch boiler for instance. Expect it need 600,000 calories for 1 hour. I work out the needed amount of natural gas as well as biomass pellets. By multiplying hemp pellet machine , we can exercise the complete cost As the kind show, biomass pellets cost a lot lower than natural gas.



Kcal/kg pricerequired quantitytotal price.

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 energy is the chemical form of solar power. It includes wood, forestry waste, crop waste, marine plant, animal dung, plant wastes. Every year, the biomass produced by photosynthesis depends on 173 billion heap, equal to 10-20 times the yearly international power consumption, however just 3% of them are made use of. As small wood pellet machine as there is sunlight, the biomass energy will certainly never run out.



In some backwoods, gas is not readily available. Meanwhile, with even more manufacturing facilities change coal-fired boilers into natural gas boiler, the price of gas is going to rise. By comparison, biomass energy is rich in backwoods. They are simple to acquire and also process, which don't take much price.



The ash deposits of wood pellets after shedding contains minerals and carbon. chicken feed making machine for sale can be utilized as plant food on farm and also in garden. You can collect the ash residues from biomass boilers for future usage.



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

Under the atmosphere protection stress, coal boilers are limited in numerous cities. Many factories have actually changed to biomass boiler or gas central heating boiler. Here I 'd like to compare the 3 central heating boilers as well as find out which is the most effective.



First financial investment.

In term of the central heating boilers with the very same capacity, gas central heating boilers call for the greatest cost, then comes biomass central heating boiler, and also coal central heating boiler for the last.



Operation cost.

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



Environment result.


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



Application area.

Coal boilers have actually been limited in numerous cities, or need to be furnished with desulfurizer. Gas supply is not uniform in various locations. Some regions do not have natural gas readily available, so biomass central heating boilers become their ideal choice.



To conclude, to meet the environment requirement, gas central heating boilers as well as biomass boilers are sensible. Gas boilers have the least discharge, however the expense is the highest. Biomass central heating boilers have inexpensive and also vast application, as well as the air pollution emission is low. So it has been preferred in several areas.
