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

The burning performance of biomass fuel is similar with tool coal, but it have such advantages over coal:



The calorific value of biomass pellets is 10% lower than medium coal. However pellet machine diy can wear out, while coals have 10-15% combustible element left in the coal slag. So in actual use, their calorific value coincide.

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

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

Coal's contaminant emission and also rust to the boiler is much more major than biomass pellets. Coal smoke consists of a great deal of fragment carbons, toxic SO2, CO as well as other corrosion gas Biomass pellets is mostly made up of C-H raw materials, the gas discharge is primarily C-H unstable gas, with little SO2 or CO exhaust. Biomass fuel is referred to as clean fuel. It can greatly decrease the air contamination as well as carbon discharge.

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



Compare biomass pellets as well as gas.

Cost of biomass pellets as well as natural gas in central heating boilers

Allow's take a 1 load boiler as an example. Intend Richi machine require 600,000 calories for 1 hr. I work out the needed quantity of gas and biomass pellets. By increasing their unit rate, we can exercise the complete expense As the kind show, biomass pellets cost much lower than gas.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Gas is a non-renewable resource, like coal and oil. Biomass power is the chemical form of solar power. It consists of timber, forestry waste, plant waste, marine plant, pet dung, plant wastes. Annually, the biomass generated by photosynthesis is up to 173 billion load, equal to 10-20 times the yearly international energy intake, but only 3% of them are made use of. As long as there is sunshine, the biomass power will never ever go out.



In some rural areas, gas is not readily available. On the other hand, with more factories transform coal-fired boilers right into gas central heating boiler, the rate of natural gas is mosting likely to rise. By contrast, biomass energy is rich in backwoods. They are simple to get and process, which don't take much price.



The ash deposits of timber pellets after melting has minerals as well as carbon. It can be used as fertilizer on farm and in yard. You can accumulate the ash deposits from biomass boilers for future usage.



Contrast of biomass central heating boiler, gas central heating boiler, as well as coal boiler.

Under the atmosphere protection pressure, coal central heating boilers are restricted in several cities. Numerous factories have actually switched over to biomass central heating boiler or gas central heating boiler. Here I would love to contrast the 3 boilers and find out which is the best.



Initial investment.

In regard to the boilers with the exact same capability, gas central heating boilers need the highest possible price, then comes biomass boiler, as well as coal central heating boiler for the last.




Operation cost.

In regards to operation price, gas central heating boiler > coal boiler > biomass boiler. The gas rate differs in various areas, greater than biomass and coal. The cost of biomass and coal are similar, yet as coal boilers have lower efficiency, the operation cost is higher than biomass central heating boiler.



Environment result.

In terms of environmental management, gas boiler > biomass boiler > coal central heating boiler. Gas boilers take on natural gas as fuel, biomass central heating boilers embrace biomass pellets or briquettes. Coal central heating boilers produce the highest possible air pollution, consisting of SO2, CO, ash, antacids, etc. Biomass central heating boilers arere environmental-friendly than coals. It only generate C, H unpredictable gases, as well as little ash deposits.



Application area.

Coal central heating boilers have been restricted in many cities, or require to be equipped with desulfurizer. Natural gas supply is not uniform in various areas. Some regions do not have gas offered, so biomass boilers become their ideal option.



To conclude, to satisfy the atmosphere requirement, gas boilers and biomass boilers are practical. Gas central heating boilers have the least exhaust, however the expense is the greatest. Biomass central heating boilers have affordable as well as vast application, as well as the contamination emission is reduced. So it has been prominent in several locations.
