Contrast biomass fuel with coal and also gas<br>
Compare biomass fuel with coal

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



The calorific value of biomass pellets is 10% lower than tool coal. Yet biomass pellets can wear out, while coals have 10-15% flammable component left in the coal slag. So in real use, their calorific value are the same.

Biomass pellets are simpler to spark than coals, which can reduce the starting time greatly.

The strong discharge of biomass pellets is lower than coal. It can lower the slag discharge charge as well as air pollution. The strong exhaust of biomass pellets are almost ash, making up 0.4% ~ 7.0% of the complete weight, while the solid emission of coal are ash, antacids, and residual coal, making up 25% -40% of the total weight.

Coal's contaminant discharge as well as corrosion to the central heating boiler is far more significant than biomass pellets. Coal smoke has a great deal of bit carbons, poisonous SO2, carbon monoxide and various other corrosion gas Biomass pellets is mainly composed of C-H raw materials, the gas discharge is mainly C-H unstable gas, with little SO2 or CO exhaust. Biomass fuel is referred to as tidy fuel. It can substantially minimize the air pollution as well as carbon exhaust.

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



Compare biomass pellets and also gas.

Cost of biomass pellets and also natural gas in boilers


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



Kcal/kg pricerequired quantitytotal expense.

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, marine plant, pet dung, plant wastes. Yearly, the biomass created by photosynthesis is up to 173 billion lot, equal to 10-20 times the annual global energy intake, but just 3% of them are utilized. As long as there is sunshine, the biomass power will never run out.



In some rural areas, gas is not available. At the same time, with more factories transform coal-fired central heating boilers right into gas central heating boiler, the price of gas is going to rise. By comparison, biomass energy is abundant in backwoods. They are very easy to obtain and also refine, which do not take much price.



The ash deposits of wood pellets after burning contains minerals and also carbon. It can be utilized as plant food on ranch and also in yard. You can collect the ash residues from biomass central heating boilers for future usage.



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

Under the environment protection pressure, coal central heating boilers are limited in numerous cities. Many factories have actually switched to biomass central heating boiler or gas central heating boiler. low cost pellet machine want to contrast the 3 boilers as well as find out which is the best.



Preliminary investment.


In regard to the central heating boilers with the exact same ability, gas central heating boilers require the greatest cost, then comes biomass central heating boiler, and coal boiler for the last.



Operation cost.

In regards to operation expense, gas central heating boiler > coal boiler > biomass central heating boiler. The gas price varies in different locations, greater than biomass as well as coal. The rate of biomass and also coal are comparable, but as coal central heating boilers have lower efficiency, the procedure price is more than biomass central heating boiler.



Environment impact.

In regards to environmental protection, gas central heating boiler > biomass central heating boiler > coal central heating boiler. Gas boilers take on natural gas as fuel, biomass boilers take on biomass pellets or briquettes. richi pellet machine generate the highest possible air pollution, including SO2, CO, ash, alkali, and so on. Biomass boilers arere environmental-friendly than coals. It just produce C, H volatile gases, and also little ash deposits.



Application location.

Coal central heating boilers have been limited in lots of cities, or require to be equipped with desulfurizer. Gas supply is not uniform in various locations. Some regions don't have gas available, so biomass boilers become their finest option.



In conclusion, to fulfill the atmosphere need, gas central heating boilers as well as biomass central heating boilers are viable. Gas central heating boilers have the least emission, however the price is the highest possible. Biomass boilers have affordable as well as large application, as well as the air pollution emission is reduced. So it has been prominent in numerous locations.
