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

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




The calorific value of biomass pellets is 10% less than medium coal. But biomass pellets can wear out, while coals have 10-15% combustible element left in the coal slag. So in actual use, their calorific worth are the same.

Biomass pellets are less complicated to spark 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 fee as well as air contamination. The solid emission of biomass pellets are nearly ash, making up 0.4% ~ 7.0% of the total weight, while the solid discharge of coal are ash, antacids, and also recurring coal, accounting for 25% -40% of the overall weight.

Coal's pollutant emission and deterioration to the boiler is much more serious than biomass pellets. Coal smoke has a lot of fragment carbons, harmful SO2, carbon monoxide as well as various other corrosion gas Biomass pellets is generally composed of C-H raw materials, the gas discharge is mostly C-H unpredictable gas, with little SO2 or carbon monoxide exhaust. Biomass fuel is know as clean fuel. small electric fish feed extruder machine price can considerably decrease the air pollution and also carbon exhaust.

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



Contrast biomass pellets as well as gas.

Cost of biomass pellets as well as gas in boilers

Let's take a 1 load central heating boiler as an example. Suppose it need 600,000 calories for 1 hour. I work out the needed amount of natural gas and also biomass pellets. By increasing their system price, we can exercise the complete cost As the kind program, biomass pellets cost a lot lower than natural gas.



Kcal/kg pricerequired quantitytotal price.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable resource, like coal as well as oil. Biomass energy is the chemical type of solar energy. It includes timber, forestry waste, plant waste, water plant, pet dung, plant wastes. Every year, the biomass generated by photosynthesis depends on 173 billion heap, equal to 10-20 times the yearly global power intake, but just 3% of them are made use of. As long as there is sunshine, the biomass energy will certainly never ever run out.



In some rural areas, gas is not readily available. On the other hand, with even more manufacturing facilities transform coal-fired central heating boilers right into natural gas boiler, the cost of gas is going to rise up. By contrast, biomass energy is abundant in rural areas. biomass pellet machine price are easy to acquire as well as process, which don't take much cost.



The ash deposits of wood pellets after melting has minerals as well as carbon. It can be utilized as plant food on farm and also in garden. You can collect the ash deposits from biomass boilers for future usage.



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

Under the setting security pressure, coal central heating boilers are limited in lots of cities. Several manufacturing facilities have changed to biomass central heating boiler or gas central heating boiler. Below I would love to compare the 3 boilers as well as identify which is the most effective.



Initial financial investment.

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



Operation price.

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




Environment impact.

In regards to environmental protection, gas central heating boiler > biomass boiler > coal boiler. Gas central heating boilers embrace gas as fuel, biomass boilers adopt biomass pellets or briquettes. Coal boilers generate the highest possible air pollution, consisting of SO2, CARBON MONOXIDE, ash, antacids, and so on. Biomass central heating boilers arere environmental-friendly than coals. It only produce C, H volatile gases, and also little ash deposits.



Application area.

Coal central heating boilers have actually been restricted in several cities, or require to be outfitted with desulfurizer. Gas supply is not uniform in various locations. Some regions do not have natural gas available, so biomass boilers become their best option.



To conclude, to fulfill the atmosphere demand, gas boilers as well as biomass central heating boilers are feasible. Gas central heating boilers have the least emission, but the cost is the greatest. Biomass boilers have low cost as well as vast application, and also the air pollution emission is reduced. So it has actually been prominent in lots of areas.
