Contrast biomass fuel with coal and gas<br>
Compare biomass fuel with coal

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



The calorific value of biomass pellets is 10% lower than medium coal. However pellet press machine for sale can burn out, while coals have 10-15% flammable component left in the coal slag. So in actual use, their calorific worth are the same.

Biomass pellets are less complicated to spark than coals, which can reduce the starting time mainly.


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


Coal's contaminant emission and also deterioration to the boiler is even more severe than biomass pellets. Coal smoke contains a great deal of fragment 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 discharge is mainly C-H unstable gas, with little SO2 or carbon monoxide discharge. Biomass fuel is referred to as tidy fuel. It can substantially decrease the air contamination as well as carbon discharge.

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



Contrast biomass pellets and gas.

Price of biomass pellets and natural gas in boilers

Allow's take a 1 load boiler for example. Mean 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 system cost, we can work out the total price As the form program, biomass pellets set you back much less 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 resource, like coal as well as oil. Biomass power is the chemical kind of solar power. It includes wood, forestry waste, plant waste, marine plant, pet dung, plant wastes. Annually, the biomass produced by photosynthesis depends on 173 billion heap, equal to 10-20 times the yearly worldwide energy consumption, but only 3% of them are made use of. As long as there is sunshine, the biomass power will certainly never ever run out.



In some rural areas, natural gas is not available. On Richi machine , with more factories change coal-fired boilers into natural gas central heating boiler, the cost of gas is mosting likely to rise up. By comparison, biomass energy is rich in backwoods. They are easy to acquire and refine, which do not take much expense.



The ash deposits of wood pellets after shedding has minerals and also carbon. It can be utilized as plant food on ranch as well as in garden. You can gather the ash deposits from biomass boilers for future use.



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

Under the setting defense stress, coal central heating boilers are limited in numerous cities. Lots of manufacturing facilities have switched over to biomass boiler or gas boiler. Below I 'd like to compare the 3 central heating boilers and determine which is the best.



Preliminary investment.

In regard to the central heating boilers with the exact same capacity, gas central heating boilers require the greatest expense, after that comes biomass boiler, as well as coal central heating boiler for the last.



Operation expense.

In terms of procedure cost, gas boiler > coal central heating boiler > biomass central heating boiler. The gas rate varies in different locations, more than biomass and also coal. The rate of biomass and also coal are comparable, yet as coal boilers have reduced effectiveness, the procedure price is higher than biomass boiler.



Environment effect.

In regards to environmental protection, gas central heating boiler > biomass central heating boiler > coal boiler. Gas boilers embrace gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal boilers produce the greatest contamination, consisting of SO2, CO, ash, antacids, and so on. Biomass boilers arere environmental-friendly than coals. It only produce C, H unstable gases, and little ash deposits.



Application area.

Coal boilers have been restricted in numerous cities, or need to be outfitted with desulfurizer. Natural gas supply is not uniform in different locations. Some regions do not have gas readily available, so biomass boilers become their finest option.



In conclusion, to fulfill the setting demand, gas central heating boilers and biomass boilers are practical. Gas boilers have the least emission, yet the price is the greatest. Biomass central heating boilers have low cost and also broad application, and also the pollution exhaust is reduced. So it has been preferred in several areas.
