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

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



The calorific value of biomass pellets is 10% lower than tool coal. However biomass pellets can burn out, while coals have 10-15% flammable element left in the coal slag. So in real use, their calorific value coincide.

Biomass pellets are less complicated to stir up than coals, which can reduce the starting time largely.

The solid discharge of biomass pellets is lower than coal. It can minimize the slag discharge fee and also air contamination. The strong emission of biomass pellets are almost ash, representing 0.4% ~ 7.0% of the complete weight, while the solid discharge of coal are ash, antacids, and also recurring coal, making up 25% -40% of the overall weight.

Coal's contaminant exhaust and deterioration to the boiler is even more major than biomass pellets. Coal smoke has a lot of fragment carbons, harmful SO2, carbon monoxide and also various other corrosion gas Biomass pellets is mainly composed of C-H raw materials, the gas emission is mainly C-H unpredictable gas, with little SO2 or CO exhaust. Biomass fuel is referred to as clean fuel. It can considerably minimize the air contamination as well as carbon emission.

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



Compare biomass pellets and also natural gas.

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

Allow's take a 1 heap central heating boiler for instance. Suppose it need 600,000 calories for 1 hour. I exercise the called for amount of natural gas and biomass pellets. By increasing their unit rate, we can exercise the overall expense As the type program, biomass pellets set you back much lower than natural gas.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

Gas is a non-renewable resource, like coal as well as oil. Biomass power is the chemical type of solar energy. It includes wood, forestry waste, plant waste, water plant, animal dung, plant wastes. Yearly, the biomass produced by photosynthesis depends on 173 billion load, equal to 10-20 times the yearly worldwide power consumption, but only 3% of them are used. As long as there is sunshine, the biomass power will never ever run out.



In some backwoods, gas is not readily available. On the other hand, with even more manufacturing facilities transform coal-fired boilers into natural gas boiler, the cost of gas is mosting likely to rise up. By you can look here , biomass energy is abundant in rural areas. They are very easy to get as well as process, which do not take much price.



The ash deposits of wood pellets after shedding has minerals and also carbon. It can be used as fertilizer on farm and in yard. You can gather the ash residues from biomass boilers for future usage.



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

Under the environment protection stress, coal boilers are limited in numerous cities. Numerous manufacturing facilities have actually switched to biomass boiler or gas boiler. Below I would love to contrast the 3 central heating boilers as well as identify which is the best.



Initial financial investment.


In regard to the central heating boilers with the very same ability, gas boilers need the greatest expense, after that comes biomass central heating boiler, and also coal boiler for the last.



Operation price.

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



Environment effect.

In regards to environmental protection, gas central heating boiler > biomass boiler > coal central heating boiler. Gas boilers take on natural gas as fuel, biomass central heating boilers embrace biomass pellets or briquettes. Coal central heating boilers produce the highest possible pollution, consisting of SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass central heating boilers arere environmental-friendly than coals. It only produce C, H unstable gases, as well as little ash residues.



Application location.

Coal central heating boilers have been limited in several cities, or require to be equipped with desulfurizer. richi pellet is not uniform in different locations. Some areas do not have gas available, so biomass central heating boilers become their ideal selection.



To conclude, to fulfill the setting requirement, gas central heating boilers as well as biomass boilers are practical. Gas boilers have the least exhaust, however the price is the highest possible. Biomass boilers have inexpensive and also large application, as well as the air pollution exhaust is reduced. So it has been prominent in several areas.
