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 tool coal, however it have such benefits over coal:



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

Biomass pellets are easier to ignite 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 cost and air contamination. The strong discharge of biomass pellets are virtually ash, making up 0.4% ~ 7.0% of the overall weight, while the strong emission of coal are ash, antacids, as well as recurring coal, representing 25% -40% of the total weight.


Coal's pollutant emission and corrosion to the central heating boiler is even more major than biomass pellets. Coal smoke contains a great deal of fragment carbons, poisonous SO2, carbon monoxide and also other corrosion gas Biomass pellets is mainly made up of C-H organic matters, the gas discharge is mostly C-H unstable gas, with little SO2 or CO exhaust. Biomass fuel is know as tidy fuel. It can considerably minimize the air contamination as well as carbon exhaust.

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



Contrast biomass pellets as well as natural gas.

Expense of biomass pellets as well as gas in boilers

Let's take a 1 ton boiler for example. Intend it require 600,000 calories for 1 hour. I work out the required quantity of natural gas as well as biomass pellets. By increasing their unit cost, we can exercise the complete price As the type show, biomass pellets cost much less than gas.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

Natural gas is a non-renewable resource, like coal and oil. Biomass power is the chemical form of solar energy. It includes wood, forestry waste, crop waste, marine plant, animal dung, plant wastes. Every year, the biomass produced by photosynthesis is up to 173 billion lot, equal to 10-20 times the annual global power intake, but only 3% of them are made use of. As richi machinery as there is sunlight, the biomass power will certainly never ever run out.



In some rural areas, gas is not available. Meanwhile, with even more factories change coal-fired boilers into natural gas boiler, the rate of gas is going to rise up. By comparison, biomass power is rich in rural areas. They are simple to acquire and process, which don't take much cost.



The ash deposits of wood pellets after burning contains minerals as well as carbon. It can be made use of as plant food on farm and also in yard. You can accumulate the ash deposits from biomass boilers for future use.



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

Under the environment protection stress, coal central heating boilers are limited in several cities. Many manufacturing facilities have changed to biomass central heating boiler or gas central heating boiler. Right here I wish to contrast the 3 boilers as well as find out which is the most effective.



First financial investment.

In regard to the boilers with the same ability, gas boilers call for the highest possible cost, then comes biomass boiler, as well as coal central heating boiler for the last.



Procedure price.

In regards to procedure expense, gas boiler > coal boiler > biomass boiler. The gas rate varies in different areas, greater than biomass and also coal. The cost of biomass as well as coal are similar, however as coal central heating boilers have lower performance, the operation price is more than biomass boiler.



Setting effect.

In regards to environmental protection, gas boiler > biomass central heating boiler > coal boiler. Gas central heating boilers take on natural gas as fuel, biomass central heating boilers adopt biomass pellets or briquettes. Coal boilers create the highest contamination, including SO2, CO, ash, alkali, and so on. Biomass central heating boilers arere environmental-friendly than coals. It just produce C, H volatile gases, as well as little ash residues.



Application area.

Coal boilers have been limited in several cities, or require to be equipped with desulfurizer. Natural gas supply is not uniform in various locations. small wood pellet machine do not have gas available, so biomass central heating boilers become their ideal selection.



In conclusion, to satisfy the setting demand, gas central heating boilers as well as biomass central heating boilers are viable. Gas central heating boilers have the least emission, yet the expense is the greatest. Biomass central heating boilers have low cost and also wide application, as well as the pollution discharge is reduced. So it has actually been popular in many locations.
