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

The burning efficiency of biomass fuel is similar with medium coal, however it have such benefits over coal:



The calorific worth of biomass pellets is 10% less than medium coal. Yet biomass pellets can stress out, while coals have 10-15% combustible component left in the coal slag. So in real usage, their calorific worth are the same.

Biomass pellets are simpler to stir up than coals, which can reduce the starting time greatly.

The solid discharge of biomass pellets is less than coal. It can minimize the slag discharge cost and air contamination. The solid emission of biomass pellets are nearly ash, representing 0.4% ~ 7.0% of the overall weight, while the strong emission of coal are ash, antacids, as well as residual coal, representing 25% -40% of the complete weight.

Coal's pollutant exhaust as well as corrosion to the boiler is much more serious than biomass pellets. Coal smoke includes a lot of bit carbons, toxic SO2, CO and also various other deterioration gas Biomass pellets is mainly made up of C-H organic matters, the gas discharge is primarily C-H volatile gas, with little SO2 or carbon monoxide emission. Biomass fuel is know as tidy fuel. It can greatly minimize the air contamination and also carbon exhaust.


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



Compare biomass pellets as well as gas.

Expense of biomass pellets and gas in central heating boilers

Let's take a 1 heap boiler for example. Mean wood pellet machine price need 600,000 calories for 1 hour. I exercise the needed quantity of natural gas as well as biomass pellets. By multiplying their device price, we can exercise the complete price As the form program, biomass pellets cost a lot less 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 resource, like coal as well as oil. Biomass energy is the chemical type of solar power. rice husk pellet machine price consists of timber, forestry waste, crop waste, water plant, animal dung, plant wastes. Yearly, the biomass generated by photosynthesis depends on 173 billion bunch, equal to 10-20 times the annual worldwide energy intake, but just 3% of them are utilized. As long as there is sunshine, the biomass energy will certainly never run out.



In some rural areas, natural gas is not offered. On the other hand, with more factories transform coal-fired central heating boilers right into natural gas central heating boiler, the price of natural gas is going to rise up. By contrast, biomass power is rich in backwoods. They are very easy to get as well as process, which don't take much expense.



The ash deposits of timber pellets after shedding includes minerals and carbon. floating fish food machine can be used as plant food on ranch as well as in garden. You can accumulate the ash deposits from biomass boilers for future usage.



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

Under the environment security pressure, coal boilers are limited in numerous cities. Lots of manufacturing facilities have switched to biomass boiler or gas central heating boiler. Here I want to contrast the 3 central heating boilers and determine which is the very best.



Preliminary financial investment.

In regard to the boilers with the very same ability, gas boilers call for the greatest cost, after that comes biomass central heating boiler, and also coal central heating boiler for the last.



Operation expense.

In regards to operation price, gas central heating boiler > coal central heating boiler > biomass central heating boiler. The gas price differs in various areas, higher than biomass as well as coal. The cost of biomass as well as coal are comparable, but as coal central heating boilers have reduced performance, the procedure expense is higher than biomass boiler.



Setting effect.

In terms of environmental protection, gas boiler > biomass boiler > coal central heating boiler. Gas boilers take on gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal central heating boilers produce the highest possible pollution, including SO2, CO, ash, antacids, and so on. Biomass central heating boilers arere environmental-friendly than coals. It only generate C, H unstable gases, as well as little ash deposits.



Application area.

Coal boilers have been limited in several cities, or require to be equipped with desulfurizer. Natural gas supply is not uniform in different areas. Some areas do not have gas available, so biomass boilers become their best choice.



Finally, to satisfy the environment requirement, gas central heating boilers and biomass boilers are practical. Gas central heating boilers have the least exhaust, yet the expense is the highest possible. Biomass central heating boilers have low cost as well as large application, as well as the contamination discharge is reduced. So it has been preferred in lots of locations.
