Compare biomass fuel with coal and natural gas
Compare biomass fuel with coal as well as gas
Contrast biomass fuel with coal
The burning efficiency of biomass fuel is similar with tool coal, however it have such advantages over coal:

The calorific worth of biomass pellets is 10% less than tool coal. But biomass pellets can burn out, while coals have 10-15% flammable part left in the coal slag. So in actual usage, their calorific worth coincide.
Biomass pellets are simpler to stir up than coals, which can shorten the starting time mainly.
The solid discharge of biomass pellets is lower than coal. It can lower the slag discharge cost and air contamination. The solid discharge of biomass pellets are virtually ash, accounting for 0.4% ~ 7.0% of the overall weight, while the solid exhaust of coal are ash, alkali, and residual coal, making up 25% -40% of the complete weight.
Coal's contaminant emission and rust to the central heating boiler is much more major than biomass pellets. Coal smoke includes a great deal of bit carbons, poisonous SO2, CO and also various other rust gas Biomass pellets is mainly made up of C-H organic matters, the gas exhaust is primarily C-H unpredictable gas, with little SO2 or carbon monoxide emission. Biomass fuel is know as clean fuel. It can significantly minimize the air pollution and carbon emission.
Fostering of biomass fuel in central heating boilers can save time and price than coals. A 0.5 t central heating boiler can conserve 10% fuel price and 16% time with biomass pellets than coal.

Compare biomass pellets and natural gas.

Allow's take a 1 bunch boiler for instance. Suppose it need 600,000 calories for 1 hr. I exercise the needed quantity of gas and also biomass pellets. By multiplying their device rate, we can exercise the total expense As the kind program, biomass pellets cost a lot lower than natural gas.


Kcal/kg pricerequired quantitytotal expense.
gas 9000 ￥ 3.6/ m366m3 ￥ 238.
biomass pellets4200 ￥ 900/t 140kg ￥ 126.


Gas is a non-renewable source, like coal and oil. Biomass power is the chemical form of solar power. press pellet machine includes wood, forestry waste, plant waste, marine plant, pet dung, plant wastes. Yearly, the biomass produced by photosynthesis depends on 173 billion ton, equal to 10-20 times the annual international energy consumption, but just 3% of them are utilized. As long as there is sunlight, the biomass power will certainly never run out.

In some rural areas, gas is not offered. Meanwhile, with more manufacturing facilities transform coal-fired boilers right into gas boiler, the price of natural gas is going to rise. By contrast, biomass energy is rich in rural areas. They are simple to acquire as well as refine, which do not take much expense.

The ash deposits of timber pellets after burning includes minerals and carbon. It can be utilized as fertilizer on farm and in garden. You can gather the ash deposits from biomass central heating boilers for future use.

Contrast of biomass central heating boiler, gas central heating boiler, and also coal boiler.
Under the atmosphere defense pressure, coal boilers are restricted in several cities. Several factories have actually changed to biomass boiler or gas central heating boiler. Here I wish to compare the 3 boilers and determine which is the very best.

Initial financial investment.

In term of the boilers with the same ability, gas boilers call for the highest possible price, then comes biomass central heating boiler, and coal boiler for the last.

Procedure price.
In terms of operation price, gas boiler > coal boiler > biomass boiler. The gas rate varies in various locations, more than biomass and coal. The price of biomass and also coal are similar, yet as coal boilers have lower effectiveness, the operation cost is greater than biomass central heating boiler.

Atmosphere effect.
In terms of environmental protection, gas boiler > biomass boiler > coal boiler. Gas boilers adopt gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal central heating boilers generate the greatest contamination, consisting of SO2, CARBON MONOXIDE, ash, antacids, and so on. Biomass boilers arere environmental-friendly than coals. It just generate C, H unstable gases, as well as little ash deposits.


Application location.
Coal boilers have actually been limited in many cities, or require to be equipped with desulfurizer. Gas supply is not uniform in different locations. Some regions do not have natural gas available, so biomass central heating boilers become their best option.

To conclude, to fulfill the atmosphere demand, gas central heating boilers and biomass boilers are feasible. Gas boilers have the least emission, yet the expense is the greatest. Biomass central heating boilers have inexpensive and wide application, and also the air pollution emission is reduced. So it has been popular in numerous areas.
