Contrast biomass fuel with coal

The burning performance of biomass fuel is similar with tool coal, however 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 component left in the coal slag. So in actual usage, their calorific value are the same.

Biomass pellets are simpler to stir up than coals, which can shorten the starting time mostly.

The strong discharge of biomass pellets is less than coal. It can lower the slag discharge cost and air contamination. The solid emission of biomass pellets are almost ash, accounting for 0.4% ~ 7.0% of the complete weight, while the strong exhaust of coal are ash, antacids, and residual coal, making up 25% -40% of the overall weight.

Coal's pollutant discharge and also deterioration to the boiler is far more significant than biomass pellets. Coal smoke includes a great deal of particle carbons, poisonous SO2, CO as well as other rust gas Biomass pellets is mostly made up of C-H organic matters, the gas discharge is mainly C-H volatile gas, with little SO2 or CO exhaust. Biomass fuel is know as tidy fuel. fish pellet machine can significantly lower the air pollution and carbon emission.

Adoption of biomass fuel in central heating boilers can save time and price than coals. Richi machine can conserve 10% fuel price and also 16% time with biomass pellets than coal.



Compare biomass pellets as well as natural gas.

Price of biomass pellets and also natural gas in boilers

Allow's take a 1 bunch central heating boiler as an example. Intend it require 600,000 calories for 1 hr. I exercise the called for quantity of natural gas as well as biomass pellets. By increasing their unit cost, we can work out the complete cost As the form program, biomass pellets cost much lower than natural gas.



Kcal/kg pricerequired quantitytotal price.

natural 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 kind of solar power. It consists of timber, forestry waste, plant waste, marine plant, animal dung, plant wastes. Each year, the biomass generated by photosynthesis is up to 173 billion load, equal to 10-20 times the annual global power usage, yet just 3% of them are used. As long as there is sunshine, the biomass energy will certainly never ever run out.



In some rural areas, gas is not offered. At the same time, with even more factories change coal-fired boilers right into gas central heating boiler, the cost of natural gas is mosting likely to rise. By comparison, biomass energy is rich in rural areas. They are easy to obtain as well as refine, which don't take much price.



The ash deposits of wood pellets after shedding consists of minerals and also carbon. It can be utilized as fertilizer on farm and also in yard. You can accumulate the ash deposits from biomass boilers for future usage.



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

Under the atmosphere defense stress, coal central heating boilers are restricted in numerous cities. Several factories have actually switched over to biomass boiler or gas central heating boiler. Right here I want to compare the 3 boilers and also determine which is the most effective.



Preliminary financial investment.

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




Procedure price.

In regards to operation price, gas boiler > coal central heating boiler > biomass boiler. The gas price varies in various areas, higher than biomass and coal. The price of biomass as well as coal are similar, yet as coal boilers have reduced effectiveness, the procedure cost is more than biomass boiler.



Environment effect.

In regards to environmental protection, gas boiler > biomass boiler > coal central heating boiler. Gas boilers adopt natural gas as fuel, biomass central heating boilers embrace biomass pellets or briquettes. Coal boilers generate the highest possible pollution, including SO2, CO, ash, antacids, etc. Biomass boilers arere environmental-friendly than coals. It only create C, H unpredictable gases, and also little ash deposits.



Application location.

Coal central heating boilers have actually been limited in several cities, or require to be equipped with desulfurizer. Gas supply is not uniform in different locations. Some regions don't have natural gas offered, so biomass central heating boilers become their finest selection.



Finally, to satisfy the environment demand, gas boilers as well as biomass boilers are feasible. Gas boilers have the least discharge, yet the expense is the greatest. chicken pellet maker have low cost as well as wide application, as well as the contamination emission is low. So it has actually been prominent in numerous locations.
