Compare biomass fuel with coal
The burning efficiency of biomass fuel is similar with tool coal, yet it have such advantages over coal:

The calorific worth of biomass pellets is 10% less than tool coal. Yet biomass pellets can stress out, while coals have 10-15% combustible part left in the coal slag. So in actual usage, their calorific worth coincide.
Biomass pellets are much easier to stir up than coals, which can reduce the starting time largely.
The solid discharge of biomass pellets is less than coal. It can decrease the slag discharge fee and air pollution. The strong exhaust of biomass pellets are practically ash, accounting for 0.4% ~ 7.0% of the total weight, while the strong discharge of coal are ash, alkali, as well as recurring coal, making up 25% -40% of the complete weight.
Coal's contaminant emission as well as corrosion to the boiler is even more major than biomass pellets. Coal smoke contains a lot of bit carbons, hazardous SO2, carbon monoxide and other corrosion gas Biomass pellets is primarily made up of C-H organic matters, the gas exhaust is mainly C-H unstable gas, with little SO2 or CO exhaust. sinking fish feed machine is know as tidy fuel. It can significantly decrease the air pollution and also carbon discharge.
Fostering of biomass fuel in boilers can save time as well as price than coals. A 0.5 t boiler can save 10% fuel price and also 16% time with biomass pellets than coal.

Contrast biomass pellets as well as natural gas.
Expense of biomass pellets as well as natural gas in central heating boilers
Let's take a 1 ton central heating boiler for example. Mean it require 600,000 calories for 1 hr. I work out the needed quantity of gas and biomass pellets. By increasing their system cost, we can exercise the total cost As the kind show, biomass pellets cost much lower than gas.


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


Gas is a non-renewable source, like coal and also oil. Biomass energy is the chemical kind of solar energy. It consists of timber, forestry waste, crop waste, water plant, pet dung, plant wastes. Each year, the biomass created by photosynthesis depends on 173 billion heap, equal to 10-20 times the yearly international power intake, however only 3% of them are made use of. As long as there is sunlight, the biomass energy will never ever go out.


In some rural areas, natural gas is not available. At the same time, with even 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. By contrast, biomass energy is abundant in backwoods. They are easy to obtain and also refine, which don't take much cost.


The ash residues of wood pellets after burning includes minerals and carbon. It can be utilized as fertilizer on ranch and in yard. You can collect the ash residues from biomass central heating boilers for future usage.

Contrast of biomass central heating boiler, gas central heating boiler, and coal central heating boiler.
Under the atmosphere defense pressure, coal central heating boilers are restricted in many cities. Lots of manufacturing facilities have actually switched to biomass central heating boiler or gas boiler. Right here I wish to contrast the 3 central heating boilers as well as find out which is the most effective.

Preliminary financial investment.
In term of the central heating boilers with the very same capacity, gas central heating boilers require the greatest price, then comes biomass boiler, and also coal central heating boiler for the last.

Operation cost.
In terms of procedure expense, gas boiler > coal central heating boiler > biomass boiler. The gas price differs in different locations, greater than biomass and coal. The rate of biomass and also coal are comparable, however as coal boilers have reduced efficiency, the operation cost is more than biomass boiler.

Environment effect.
In regards to environmental management, gas central heating boiler > biomass boiler > coal boiler. Gas central heating boilers take on natural gas as fuel, biomass boilers embrace biomass pellets or briquettes. Coal boilers create the highest possible air pollution, consisting of SO2, CARBON MONOXIDE, ash, antacids, and so on. Biomass boilers arere environmental-friendly than coals. It only produce C, H volatile gases, and little ash residues.

Application area.
Coal boilers have actually been limited in numerous cities, or require to be equipped with desulfurizer. Gas supply is not uniform in different locations. Some regions do not have gas available, so biomass central heating boilers become their best selection.

To conclude, to satisfy the setting demand, gas boilers and also biomass boilers are feasible. Gas boilers have the least discharge, yet the expense is the highest. Biomass central heating boilers have low cost and also broad application, and the air pollution exhaust is low. So it has been prominent in many locations.
