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



The burning efficiency of biomass fuel is similar 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 wear out, while coals have 10-15% flammable part left in the coal slag. So in actual usage, their calorific worth coincide.

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

The solid discharge of biomass pellets is lower than coal. It can decrease the slag discharge charge and also air contamination. The solid emission of biomass pellets are virtually ash, representing 0.4% ~ 7.0% of the total weight, while the strong exhaust of coal are ash, antacids, and recurring coal, representing 25% -40% of the overall weight.

Coal's pollutant discharge as well as deterioration to the boiler is far more serious than biomass pellets. richi pellet mill has a lot of bit carbons, harmful SO2, CO and also various other corrosion gas Biomass pellets is primarily made up of C-H organic matters, the gas exhaust is primarily C-H unpredictable gas, with little SO2 or carbon monoxide exhaust. Biomass fuel is know as tidy fuel. It can significantly reduce the air contamination as well as carbon discharge.

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



Contrast biomass pellets and also gas.

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

Allow's take a 1 heap central heating boiler as an example. Intend it require 600,000 calories for 1 hr. I work out the required amount of natural gas and biomass pellets. By multiplying their unit price, we can exercise the complete cost As the type program, biomass pellets cost a lot less than gas.



Kcal/kg pricerequired quantitytotal price.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable source, like coal and also oil. Biomass power is the chemical kind of solar energy. rabbit pellet making machine includes wood, forestry waste, crop waste, water plant, pet dung, plant wastes. Each year, the biomass generated by photosynthesis is up to 173 billion load, equal to 10-20 times the annual global power consumption, however only 3% of them are used. As long as there is sunshine, the biomass power will certainly never ever run out.



In some rural areas, natural gas is not offered. On the other hand, with more manufacturing facilities transform coal-fired central heating boilers right into natural gas central heating boiler, the rate of natural gas is mosting likely to rise up. By contrast, biomass power is abundant in rural areas. They are easy to obtain and refine, which don't take much price.



The ash deposits of wood pellets after shedding consists of minerals and carbon. It can be made use of as fertilizer on ranch and in yard. You can accumulate the ash residues from biomass central heating boilers for future usage.



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

Under the setting defense pressure, coal boilers are restricted in numerous cities. Lots of manufacturing facilities have actually switched to biomass central heating boiler or gas central heating boiler. Below I wish to contrast the 3 boilers and also find out which is the best.



Initial financial investment.

In term of the boilers with the very same ability, gas central heating boilers require the highest possible expense, after that comes biomass central heating boiler, and also coal central heating boiler for the last.



Operation expense.

In regards to procedure price, gas central heating boiler > coal central heating boiler > biomass central heating boiler. The gas cost varies in different locations, more than biomass and coal. The rate of biomass and coal are comparable, yet as coal boilers have lower effectiveness, the procedure cost is more than biomass boiler.



Environment result.

In terms of environmental management, gas central heating boiler > biomass central heating boiler > coal central heating boiler. Gas central heating boilers adopt natural gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal central heating boilers generate the greatest contamination, consisting of SO2, CO, ash, antacids, and so on. Biomass boilers arere environmental-friendly than coals. It only generate C, H unpredictable gases, as well as little ash deposits.



Application location.

Coal central heating boilers have been restricted in many cities, or require to be equipped with desulfurizer. Gas supply is not uniform in various areas. Some areas don't have gas available, so biomass central heating boilers become their finest selection.



In conclusion, to satisfy the environment requirement, gas central heating boilers and biomass central heating boilers are viable. Gas boilers have the least emission, but the expense is the highest. Biomass boilers have inexpensive and also broad application, and the pollution discharge is reduced. So it has been popular in several areas.
