The burning performance of biomass fuel is similar with tool coal, but it have such benefits over coal:
The calorific value of biomass pellets is 10% less than tool coal. But biomass pellets can wear out, while coals have 10-15% flammable element left in the coal slag. So in real use, their calorific value are the same.
Biomass pellets are less complicated to stir up than coals, which can reduce the starting time mainly.
The solid discharge of biomass pellets is lower than coal. It can decrease the slag discharge charge as well as air contamination. The solid discharge of biomass pellets are practically ash, accounting for 0.4% ~ 7.0% of the overall weight, while the strong emission of coal are ash, antacids, and recurring coal, representing 25% -40% of the overall weight.
Coal's toxin discharge as well as rust to the central heating boiler is much more severe than biomass pellets. Coal smoke includes a great deal of fragment carbons, toxic SO2, carbon monoxide as well as various other rust gas Biomass pellets is mainly made up of C-H organic matters, the gas emission is generally C-H unstable gas, with little SO2 or carbon monoxide discharge. Biomass fuel is referred to as tidy fuel. It can significantly lower the air pollution and also carbon discharge.
Fostering of biomass fuel in boilers can conserve time and also price than coals. A 0.5 t central heating boiler can save 10% fuel expense and 16% time with biomass pellets than coal.
Compare biomass pellets and gas.
Cost of biomass pellets as well as natural gas in central heating boilers
Allow's take a 1 ton central heating boiler for instance. Suppose it require 600,000 calories for 1 hr. I exercise the called for quantity of natural gas as well as biomass pellets. By multiplying their unit cost, we can exercise the complete cost As the form show, biomass pellets set you back much lower than natural gas.
Kcal/kg pricerequired quantitytotal price.
natural gas 9000 3.6/ m366m3 238.

Natural gas is a non-renewable resource, like coal and also oil. Biomass power is the chemical form of solar energy. It consists of timber, forestry waste, plant waste, water plant, animal dung, plant wastes. Each year, the biomass produced by photosynthesis depends on 173 billion ton, equal to 10-20 times the yearly international energy intake, but just 3% of them are utilized. As wood pellet machine as there is sunshine, the biomass power will certainly never go out.
In some rural areas, gas is not available. On the other hand, with even more factories transform coal-fired boilers into natural gas central heating boiler, the price of natural gas is going to rise up. By contrast, biomass power is rich in rural areas. They are very easy to acquire and also refine, which don't take much cost.
The ash deposits of timber pellets after melting includes minerals and carbon. It can be utilized as fertilizer on farm as well as in garden. You can accumulate the ash deposits from biomass boilers for future usage.
Contrast of biomass central heating boiler, gas boiler, and coal boiler.
Under the environment security stress, coal boilers are restricted in numerous cities. Several manufacturing facilities have changed to biomass central heating boiler or gas central heating boiler. Right here I 'd like to contrast the 3 central heating boilers and also identify which is the very best.
Initial financial investment.
In regard to the boilers with the very same ability, gas central heating boilers require the highest cost, after that comes biomass central heating boiler, and also coal boiler for the last.
Operation price.
In regards to procedure expense, gas central heating boiler > coal boiler > biomass central heating boiler. The gas rate varies in different locations, more than biomass and coal. The rate of biomass as well as coal are comparable, however as coal boilers have lower performance, the procedure price is more than biomass central heating boiler.
Setting result.
In terms of environmental protection, gas central heating boiler > biomass central heating boiler > coal boiler. Gas central heating boilers embrace natural gas as fuel, biomass boilers adopt biomass pellets or briquettes. Coal central heating boilers create the highest possible air pollution, consisting of SO2, CARBON MONOXIDE, ash, antacids, etc. Biomass boilers arere environmental-friendly than coals. It just create C, H volatile gases, and also little ash residues.
Application area.
Coal boilers have actually been restricted in many cities, or require to be equipped with desulfurizer. Gas supply is not uniform in various locations. Some areas do not have gas readily available, so biomass 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 emission, however the cost is the greatest. richi pellet production line have affordable as well as broad application, and also the pollution discharge is reduced. So it has been popular in lots of locations.
