Compare biomass fuel with coal

The burning performance of biomass fuel is comparable with medium coal, yet it have such benefits over coal:



The calorific worth of biomass pellets is 10% less than tool coal. However biomass pellets can wear out, while coals have 10-15% combustible part left in the coal slag. So in real use, their calorific value coincide.

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

The solid discharge of biomass pellets is less than coal. It can lower the slag discharge charge as well as air contamination. The solid discharge of biomass pellets are practically ash, making up 0.4% ~ 7.0% of the overall weight, while the solid emission of coal are ash, alkali, and also residual coal, accounting for 25% -40% of the total weight.

Coal's toxin emission and also rust to the central heating boiler is far more significant than biomass pellets. Coal smoke consists of a great deal of fragment carbons, toxic SO2, CO and various other corrosion gas Biomass pellets is primarily made up of C-H raw materials, the gas emission is mainly C-H volatile gas, with little SO2 or carbon monoxide exhaust. Biomass fuel is called tidy fuel. It can significantly minimize the air contamination as well as carbon exhaust.

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



Compare biomass pellets and gas.

Price of biomass pellets and gas in boilers

Let's take a 1 lot boiler as an example. Mean it require 600,000 calories for 1 hr. I exercise the called for quantity of gas as well as biomass pellets. By increasing their system cost, we can work out the total price As the kind program, biomass pellets cost a lot lower than gas.



Kcal/kg pricerequired quantitytotal expense.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable source, like coal and also oil. Biomass power is the chemical form of solar energy. It consists of wood, forestry waste, crop waste, marine plant, animal dung, plant wastes. Yearly, the biomass created by photosynthesis depends on 173 billion ton, equal to 10-20 times the yearly global energy usage, however just 3% of them are utilized. As long as there is sunlight, the biomass power will never go out.



In some rural areas, natural gas is not available. At the same time, with even more manufacturing facilities transform coal-fired central heating boilers right into gas boiler, the rate of natural gas is mosting likely to rise. By mini pellet machine price , biomass power is abundant in rural areas. They are simple to acquire and also refine, which don't take much price.



The ash deposits of timber pellets after burning contains minerals and also carbon. It can be made use of as plant food on ranch and also in garden. You can accumulate the ash residues from biomass central heating boilers for future usage.



Comparison of biomass boiler, gas boiler, and coal boiler.


Under the atmosphere security stress, coal boilers are limited in numerous cities. Lots of factories have changed to biomass central heating boiler or gas boiler. Right here I 'd like to compare the 3 boilers as well as figure out which is the very best.




Initial financial investment.

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



Operation cost.

In regards to procedure expense, gas boiler > coal boiler > biomass central heating boiler. The gas rate differs in different locations, more than biomass and also coal. The rate of biomass and also coal are comparable, but as coal central heating boilers have reduced performance, the operation price is higher than biomass central heating boiler.



Setting result.

In terms of environmental protection, gas central heating boiler > biomass central heating boiler > coal boiler. Gas boilers adopt natural gas as fuel, biomass central heating boilers adopt biomass pellets or briquettes. Coal boilers generate the greatest contamination, consisting of SO2, CARBON MONOXIDE, ash, antacids, etc. Biomass boilers arere environmental-friendly than coals. It only create C, H volatile gases, as well as little ash residues.



Application location.

Coal central heating boilers have been restricted in lots of cities, or require to be geared up with desulfurizer. Natural gas supply is not uniform in different locations. Some areas don't have gas offered, so biomass boilers become their ideal selection.



Finally, to meet the environment need, gas boilers as well as biomass boilers are sensible. Gas boilers have the least emission, yet the price is the highest possible. small wood pellet mill have inexpensive and also broad application, as well as the contamination emission is reduced. So it has actually been prominent in lots of areas.
