Contrast biomass fuel with coal and also natural gas<br>
Contrast 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% less than medium coal. However biomass pellets can burn out, while coals have 10-15% flammable component left in the coal slag. So in actual usage, their calorific value coincide.

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

The strong discharge of biomass pellets is less than coal. It can reduce the slag discharge fee as well as air contamination. The solid discharge of biomass pellets are practically ash, representing 0.4% ~ 7.0% of the complete weight, while the strong discharge of coal are ash, alkali, and recurring coal, representing 25% -40% of the complete weight.

Coal's toxin exhaust and deterioration to the boiler is even more significant than biomass pellets. Coal smoke consists of a lot of particle carbons, hazardous SO2, CO and various other corrosion gas Biomass pellets is mainly composed of C-H organic matters, the gas discharge is primarily C-H unpredictable gas, with little SO2 or CO emission. Biomass fuel is know as clean fuel. It can greatly lower the air contamination and carbon exhaust.

Adoption of biomass fuel in central heating boilers can save time and price than coals. A 0.5 t central heating boiler can save 10% fuel cost as well as 16% time with biomass pellets than coal.



Compare biomass pellets as well as natural gas.

Price of biomass pellets and also gas in boilers

Allow's take a 1 lot central heating boiler for instance. Intend it require 600,000 calories for 1 hour. I exercise the called for quantity of gas and biomass pellets. By increasing their unit cost, we can work out the complete cost As the kind program, biomass pellets set you back much lower than gas.



Kcal/kg pricerequired quantitytotal cost.

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 power is the chemical form of solar power. It includes timber, forestry waste, crop waste, marine plant, pet dung, plant wastes. Each year, the biomass created by photosynthesis depends on 173 billion lot, equal to 10-20 times the yearly international power usage, yet just 3% of them are made use of. As long as there is sunshine, the biomass energy will never ever run out.



In some backwoods, natural gas is not available. Meanwhile, with even more manufacturing facilities change coal-fired central heating boilers right into natural gas boiler, the price of natural gas is going to rise. By comparison, biomass energy is abundant in backwoods. They are easy to obtain as well as refine, which don't take much price.



The ash residues of timber pellets after burning contains minerals and also carbon. It can be used as plant food on farm as well as in yard. You can collect the ash residues from biomass central heating boilers for future usage.




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

Under the atmosphere defense stress, coal boilers are limited in lots of cities. Lots of manufacturing facilities have actually changed to biomass boiler or gas central heating boiler. Here I want to compare the 3 boilers and also identify which is the most effective.



First investment.

In term of the boilers with the exact same ability, gas central heating boilers call for the greatest expense, then comes biomass boiler, and coal central heating boiler for the last.



Operation expense.

In regards to operation price, gas boiler > coal boiler > biomass central heating boiler. The gas cost differs in different areas, greater than biomass and also coal. home wood pellet maker of biomass and coal are comparable, but as coal central heating boilers have lower effectiveness, the operation expense is greater than biomass boiler.



Setting impact.

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



Application area.

Coal boilers have been limited in many cities, or require to be outfitted with desulfurizer. Natural gas supply is not uniform in various areas. feed pellet machine price don't have gas readily available, so biomass boilers become their finest choice.



In conclusion, to satisfy the atmosphere demand, gas boilers and biomass boilers are feasible. Gas central heating boilers have the least discharge, but the expense is the greatest. Biomass central heating boilers have affordable and wide application, and the pollution exhaust is low. So it has been preferred in lots of areas.
