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

The burning efficiency of biomass fuel is similar with tool coal, however it have such benefits over coal:



The calorific value of biomass pellets is 10% lower than tool coal. Yet alfalfa pellet mill for sale can stress out, while coals have 10-15% combustible element left in the coal slag. So in real use, their calorific worth coincide.

Biomass pellets are less complicated to fire up than coals, which can shorten the starting time mainly.

The strong discharge of biomass pellets is lower than coal. It can decrease the slag discharge cost as well as air contamination. The solid discharge of biomass pellets are virtually ash, representing 0.4% ~ 7.0% of the overall weight, while the strong discharge of coal are ash, alkali, as well as residual coal, representing 25% -40% of the complete weight.

Coal's toxin emission and deterioration to the central heating boiler is even more severe than biomass pellets. Coal smoke has a great deal of bit carbons, hazardous SO2, carbon monoxide and also other corrosion gas Biomass pellets is primarily composed of C-H raw materials, the gas discharge is generally C-H unpredictable gas, with little SO2 or CO discharge. Biomass fuel is referred to as tidy fuel. It can significantly decrease the air pollution and carbon discharge.

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




Compare biomass pellets and also natural gas.

Expense of biomass pellets and gas in boilers

Allow's take a 1 lot central heating boiler for instance. Mean it need 600,000 calories for 1 hr. I work out the called for amount of gas and also biomass pellets. By multiplying their system cost, we can work out the overall expense As the kind show, biomass pellets set you back a lot lower than natural gas.



Kcal/kg pricerequired quantitytotal cost.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable source, like coal and oil. Biomass energy is the chemical type of solar energy. It includes timber, forestry waste, plant waste, marine plant, pet dung, plant wastes. Yearly, the biomass produced by photosynthesis is up to 173 billion lot, equal to 10-20 times the yearly worldwide power consumption, however just 3% of them are utilized. As long as there is sunlight, the biomass power will never run out.



In some backwoods, natural gas is not available. On the other hand, with more manufacturing facilities change coal-fired boilers right into gas central heating boiler, the price of natural gas is mosting likely to rise. By contrast, biomass energy is rich in backwoods. They are very easy to obtain and refine, which don't take much price.



The ash deposits of timber pellets after burning has minerals and also carbon. It can be made use of as fertilizer on ranch as well as in yard. You can collect the ash deposits from biomass boilers for future usage.



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

Under the atmosphere security pressure, coal boilers are restricted in numerous cities. Many manufacturing facilities have actually switched over to biomass boiler or gas boiler. Here I wish to compare the 3 central heating boilers and find out which is the best.



Initial financial investment.

In regard to the boilers with the very same capability, gas boilers need the greatest cost, then comes biomass boiler, and coal central heating boiler for the last.



Procedure cost.

In terms of procedure price, gas boiler > coal central heating boiler > biomass central heating boiler. alfalfa pellet making machine differs in various areas, more than biomass as well as coal. The rate of biomass as well as coal are similar, yet as coal boilers have reduced performance, the operation cost is higher than biomass boiler.



Atmosphere impact.

In terms of environmental management, gas central heating boiler > biomass central heating boiler > coal boiler. Gas central heating boilers take on natural gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal boilers produce the highest possible contamination, including SO2, CARBON MONOXIDE, ash, alkali, and so on. Biomass boilers arere environmental-friendly than coals. It just produce C, H unstable gases, as well as little ash deposits.




Application area.

Coal central heating boilers have actually been restricted in numerous cities, or require to be furnished with desulfurizer. Natural gas supply is not uniform in different locations. Some areas do not have gas available, so biomass central heating boilers become their best selection.



In conclusion, to fulfill the environment demand, gas central heating boilers as well as biomass boilers are practical. Gas central heating boilers have the least emission, however the expense is the highest possible. Biomass boilers have affordable as well as large application, and also the pollution exhaust is low. So it has been prominent in lots of areas.
