Contrast biomass fuel with coal


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

The calorific value of biomass pellets is 10% less than medium coal. Yet biomass pellets can stress out, while coals have 10-15% combustible part left in the coal slag. So in actual use, their calorific worth coincide.
Biomass pellets are easier to spark than coals, which can reduce the starting time largely.
The strong discharge of biomass pellets is lower than coal. It can decrease the slag discharge cost and air pollution. The solid emission of biomass pellets are almost ash, accounting for 0.4% ~ 7.0% of the total weight, while the strong emission of coal are ash, antacids, and also residual coal, representing 25% -40% of the total weight.
Coal's pollutant exhaust and also corrosion to the central heating boiler is even more significant than biomass pellets. Coal smoke contains a lot of fragment carbons, poisonous SO2, CO and various 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 exhaust. Biomass fuel is called clean fuel. It can considerably reduce the air contamination and also carbon discharge.
Adoption of biomass fuel in boilers can save time as well as cost than coals. A 0.5 t boiler can save 10% fuel cost and 16% time with biomass pellets than coal.

Compare biomass pellets and also gas.
Cost of biomass pellets as well as gas in boilers
Let's take a 1 heap boiler for example. Mean it require 600,000 calories for 1 hr. I work out the needed quantity of natural gas and also biomass pellets. By increasing their unit cost, we can work out the total price As the type program, biomass pellets set you back a lot less than natural gas.


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


Gas is a non-renewable source, like coal and oil. Biomass energy is the chemical kind of solar power. yulong pellet mill consists of wood, forestry waste, crop waste, aquatic plant, pet dung, plant wastes. Yearly, the biomass generated by photosynthesis depends on 173 billion heap, equal to 10-20 times the yearly international energy consumption, however only 3% of them are used. As long as there is sunlight, the biomass power will never ever go out.

In some rural areas, natural gas is not available. At the same time, with even more factories transform coal-fired boilers into gas central heating boiler, the rate of natural gas is mosting likely to rise. By contrast, biomass power is abundant in rural areas. They are very easy to acquire and also process, which don't take much expense.

The ash residues of timber pellets after burning includes minerals and also carbon. It can be made use of as fertilizer on farm as well as in yard. You can accumulate the ash residues from biomass central heating boilers for future usage.

Contrast of biomass boiler, gas boiler, and also coal central heating boiler.
Under the setting security pressure, coal central heating boilers are restricted in several cities. Many manufacturing facilities have actually switched over to biomass central heating boiler or gas central heating boiler. Right here I want to contrast the 3 central heating boilers and also identify which is the most effective.

First financial investment.
In regard to the central heating boilers with the exact same capacity, gas boilers need the highest possible cost, then comes biomass boiler, as well as coal boiler for the last.

manual fish feed pellet machine .
In regards to procedure price, gas boiler > coal central heating boiler > biomass central heating boiler. The gas price varies in different areas, greater than biomass and coal. The cost of biomass and also coal are comparable, yet as coal boilers have lower performance, the procedure price is higher than biomass boiler.

Atmosphere result.
In regards to environmental management, gas central heating boiler > biomass central heating boiler > coal boiler. Gas boilers embrace gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal central heating boilers generate the highest possible contamination, including SO2, CARBON MONOXIDE, ash, antacids, etc. Biomass boilers arere environmental-friendly than coals. It only generate C, H unstable gases, and also little ash residues.

Application location.
Coal boilers have actually been restricted in lots of cities, or require to be equipped with desulfurizer. Gas supply is not uniform in different areas. Some areas don't have natural gas offered, so biomass boilers become their ideal selection.

Finally, to meet the atmosphere requirement, gas central heating boilers and also biomass central heating boilers are feasible. hay pellet machine for sale have the least discharge, but the cost is the highest. Biomass central heating boilers have low cost as well as broad application, as well as the air pollution exhaust is low. So it has been popular in many locations.
