Contrast biomass fuel with coal

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



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

Biomass pellets are less complicated to ignite than coals, which can reduce the starting time greatly.

The strong discharge of biomass pellets is less than coal. It can reduce the slag discharge charge and also air pollution. The solid exhaust of biomass pellets are practically ash, making up 0.4% ~ 7.0% of the complete weight, while the solid emission of coal are ash, antacids, as well as residual coal, making up 25% -40% of the overall weight.

Coal's pollutant emission and also deterioration to the central heating boiler is even more significant than biomass pellets. Coal smoke contains a great deal of particle carbons, poisonous SO2, carbon monoxide as well as other corrosion gas Biomass pellets is generally made up of C-H organic matters, the gas exhaust is mainly C-H volatile gas, with little SO2 or carbon monoxide emission. Biomass fuel is called clean fuel. It can significantly reduce the air pollution and also carbon exhaust.

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



Contrast biomass pellets as well as natural gas.

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

Allow's take a 1 heap central heating boiler for instance. Suppose it need 600,000 calories for 1 hour. I exercise the required quantity of natural gas and biomass pellets. By multiplying their unit cost, we can exercise the overall price As the type program, biomass pellets cost a lot lower than natural gas.



Kcal/kg pricerequired quantitytotal cost.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable source, like coal as well as oil. Biomass energy is the chemical form of solar power. It consists of wood, forestry waste, plant waste, aquatic plant, animal dung, plant wastes. Every year, the biomass produced by photosynthesis depends on 173 billion heap, equal to 10-20 times the annual worldwide energy intake, however just 3% of them are made use of. As long as there is sunlight, the biomass power will never run out.



In some rural areas, gas is not offered. On the other hand, with more factories transform coal-fired boilers into gas central heating boiler, the cost of gas is mosting likely to rise up. By comparison, biomass energy is abundant in rural areas. They are easy to obtain as well as process, which don't take much cost.



The ash residues of timber pellets after shedding consists of minerals and carbon. It can be utilized as plant food on ranch as well as in garden. You can collect the ash residues from biomass central heating boilers for future usage.



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

Under the environment protection pressure, coal boilers are restricted in several cities. Several factories have switched to biomass central heating boiler or gas boiler. Here I want to compare the 3 central heating boilers and 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 greatest expense, then comes biomass boiler, and also coal boiler for the last.




Procedure cost.

In terms of operation expense, gas central heating boiler > coal boiler > biomass central heating boiler. The gas cost varies in various locations, higher than biomass and also coal. fish feed pellet machine of biomass and also coal are similar, but as coal boilers have lower effectiveness, the operation price is higher than biomass central heating boiler.




Atmosphere effect.

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



Application location.

Coal boilers have actually been restricted in many cities, or need to be equipped with desulfurizer. Gas supply is not uniform in various areas. Some regions don't have natural gas readily available, so biomass central heating boilers become their ideal option.



Finally, to meet the setting need, gas central heating boilers and biomass central heating boilers are practical. Gas central heating boilers have the least exhaust, but the expense is the highest possible. Biomass central heating boilers have low cost and vast application, and also the pollution exhaust is low. So it has actually been popular in numerous areas.
