Contrast biomass fuel with coal

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



The calorific value of biomass pellets is 10% lower than tool coal. But biomass pellets can burn out, while coals have 10-15% flammable component left in the coal slag. So in real usage, their calorific value coincide.

Biomass pellets are easier to stir up than coals, which can shorten the starting time mostly.

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

Coal's contaminant exhaust and also rust to the central heating boiler is even more serious than biomass pellets. Coal smoke consists of a great deal of bit carbons, harmful SO2, carbon monoxide as well as various other corrosion gas Biomass pellets is mainly made up of C-H organic matters, the gas exhaust is primarily C-H unpredictable gas, with little SO2 or carbon monoxide emission. cpm 3000 pellet mill is referred to as clean fuel. It can greatly decrease the air pollution and also carbon discharge.

Fostering of biomass fuel in central heating boilers can conserve time as well as cost than coals. small poultry feed making machine can conserve 10% fuel cost as well as 16% time with biomass pellets than coal.



Compare biomass pellets and also gas.

Price of biomass pellets and also natural gas in central heating boilers


Let's take a 1 ton central heating boiler as an example. Expect it require 600,000 calories for 1 hour. I work out the required quantity of natural gas and biomass pellets. By increasing their device cost, we can exercise the complete expense As the type show, biomass pellets set you back much lower than gas.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable resource, like coal and also oil. Biomass energy is the chemical form of solar energy. It includes wood, forestry waste, crop waste, aquatic plant, animal dung, plant wastes. Each year, the biomass created by photosynthesis depends on 173 billion lot, equal to 10-20 times the yearly worldwide power intake, however just 3% of them are used. As long as there is sunshine, the biomass energy will never ever go out.



In some rural areas, gas is not readily available. Meanwhile, with more manufacturing facilities change coal-fired central heating boilers right into natural gas central heating boiler, the rate of natural gas is going to rise up. By contrast, biomass energy is abundant in rural areas. They are very easy to get and also process, which don't take much price.



The ash deposits of timber pellets after shedding contains minerals and also carbon. It can be used as fertilizer on ranch and in yard. You can gather the ash residues from biomass boilers for future usage.



Contrast of biomass boiler, gas boiler, and also coal boiler.

Under the atmosphere defense stress, coal central heating boilers are restricted in many cities. Several factories have actually switched over to biomass central heating boiler or gas boiler. Right here I 'd like to compare the 3 central heating boilers as well as identify which is the very best.



Initial investment.

In term of the central heating boilers with the exact same capacity, gas central heating boilers require the highest possible cost, after that comes biomass central heating boiler, as well as coal boiler for the last.



Procedure price.

In regards to procedure price, gas boiler > coal central heating boiler > biomass central heating boiler. The gas price varies in different locations, more than biomass and also coal. The rate of biomass and coal are similar, yet as coal central heating boilers have reduced effectiveness, the procedure cost is more 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 boilers adopt natural gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal boilers create the highest possible pollution, consisting of SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It only produce C, H unstable gases, as well as little ash residues.




Application area.

Coal boilers have been limited in lots of cities, or need to be furnished with desulfurizer. Gas supply is not uniform in various locations. Some regions don't have gas available, so biomass central heating boilers become their ideal choice.



Finally, to meet the atmosphere demand, gas central heating boilers as well as biomass central heating boilers are practical. Gas central heating boilers have the least emission, but the cost is the highest possible. Biomass central heating boilers have inexpensive and also wide application, and also the pollution emission is reduced. So it has been prominent in several locations.
