Contrast biomass fuel with coal

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




The calorific value of biomass pellets is 10% less than medium coal. But biomass pellets can burn out, while coals have 10-15% combustible part left in the coal slag. So in actual usage, their calorific value coincide.

Biomass pellets are easier to fire up than coals, which can reduce the starting time largely.

The solid discharge of biomass pellets is less than coal. It can lower the slag discharge charge and air contamination. small pellet machine price of biomass pellets are nearly ash, making up 0.4% ~ 7.0% of the complete weight, while the strong discharge of coal are ash, antacids, and residual coal, accounting for 25% -40% of the overall weight.

Coal's pollutant exhaust as well as corrosion to the boiler is even more serious than biomass pellets. Coal smoke contains a great deal of particle carbons, poisonous SO2, carbon monoxide and also various other deterioration gas Biomass pellets is mainly composed of C-H organic matters, the gas emission is generally C-H unstable gas, with little SO2 or carbon monoxide emission. Biomass fuel is know as clean fuel. It can greatly decrease the air contamination as well as carbon emission.

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



Contrast biomass pellets and gas.

Cost of biomass pellets as well as natural gas in central heating boilers

Let's take a 1 lot boiler for instance. Intend it require 600,000 calories for 1 hr. pellet machine die work out the required amount of gas and biomass pellets. By multiplying their system rate, we can exercise the overall price As the kind show, biomass pellets set you back much less than gas.

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 power is the chemical type of solar energy. It includes wood, forestry waste, crop waste, water plant, animal dung, plant wastes. Yearly, the biomass created by photosynthesis is up to 173 billion heap, equal to 10-20 times the annual worldwide power intake, however only 3% of them are used. As long as there is sunshine, the biomass energy will certainly never run out.



In some rural areas, natural gas is not available. On the other hand, with more manufacturing facilities change coal-fired boilers into natural gas boiler, the cost of natural gas is mosting likely to rise up. By contrast, biomass energy is rich in rural areas. They are simple to obtain and also process, which don't take much price.



The ash deposits of timber pellets after melting includes minerals and carbon. livestock feed pellet machine can be used as plant food on farm as well as in garden. You can collect the ash residues from biomass boilers for future use.



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

Under the atmosphere security stress, coal boilers are restricted in lots of cities. Many factories have actually switched to biomass boiler or gas central heating boiler. Here I would love to contrast the 3 boilers as well as figure out which is the most effective.



First financial investment.

In term of the boilers with the same ability, gas central heating boilers need the highest possible cost, then comes biomass boiler, as well as coal central heating boiler for the last.



Operation cost.

In regards to operation expense, gas boiler > coal boiler > biomass central heating boiler. The gas price varies in various locations, greater than biomass and also coal. The cost of biomass and also coal are similar, yet as coal central heating boilers have reduced performance, the procedure price is greater than biomass central heating boiler.



Environment effect.

In terms of environmental management, gas boiler > biomass central heating boiler > coal boiler. Gas boilers embrace gas as fuel, biomass central heating boilers adopt biomass pellets or briquettes. Coal central heating boilers generate the greatest contamination, including SO2, CARBON MONOXIDE, ash, alkali, and so on. Biomass boilers arere environmental-friendly than coals. It just produce C, H unpredictable gases, and also little ash deposits.



Application location.

Coal central heating boilers have been limited in lots of cities, or require to be geared up with desulfurizer. Natural gas supply is not uniform in different locations. Some regions do not have natural gas offered, so biomass boilers become their ideal selection.



Finally, to fulfill the atmosphere demand, gas boilers as well as biomass boilers are feasible. Gas central heating boilers have the least exhaust, however the cost is the highest. Biomass boilers have affordable and also broad application, and the pollution discharge is reduced. So it has actually been preferred in lots of locations.
