Compare biomass fuel with coal as well as gas<br>
Contrast biomass fuel with coal

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



The calorific value of biomass pellets is 10% less than medium coal. Yet biomass pellets can burn out, while coals have 10-15% combustible element left in the coal slag. So in actual usage, their calorific worth coincide.

Biomass pellets are simpler to spark than coals, which can shorten the starting time greatly.

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

Coal's pollutant exhaust and corrosion to the central heating boiler is even more significant than biomass pellets. Coal smoke consists of a lot of bit carbons, poisonous SO2, CO and also various other rust gas Biomass pellets is primarily composed of C-H raw materials, the gas discharge is mainly C-H unstable gas, with little SO2 or carbon monoxide emission. Biomass fuel is referred to as clean fuel. It can significantly lower the air contamination and also carbon discharge.

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



Contrast biomass pellets as well as natural gas.

Cost of biomass pellets and also natural gas in boilers

Allow's take a 1 load boiler for example. Mean it need 600,000 calories for 1 hr. I exercise the required quantity of natural gas as well as biomass pellets. By multiplying their unit rate, we can work out the total cost As the kind program, biomass pellets set you back a lot less than natural gas.



Kcal/kg pricerequired quantitytotal expense.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable source, like coal and also oil. Biomass power is the chemical kind of solar power. food pellet mill consists of wood, forestry waste, crop waste, marine plant, pet dung, plant wastes. Every year, the biomass generated by photosynthesis is up to 173 billion load, equal to 10-20 times the yearly worldwide power consumption, yet just 3% of them are used. As long as there is sunlight, the biomass power will never ever run out.



In some backwoods, natural gas is not available. On the other hand, with more manufacturing facilities transform coal-fired central heating boilers right into gas boiler, the rate of gas is mosting likely to rise. By Richi machine , biomass energy is abundant in backwoods. They are easy to get and also process, which don't take much price.



The ash deposits of wood pellets after shedding includes minerals and also carbon. It can be used as plant food on farm and in yard. You can gather the ash deposits from biomass boilers for future use.



Contrast of biomass boiler, gas boiler, and also coal boiler.

Under the atmosphere security stress, coal boilers are limited in several cities. Numerous manufacturing facilities have changed to biomass boiler or gas central heating boiler. Below I want to contrast the 3 boilers and also determine which is the very best.



Initial financial investment.

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



Operation expense.

In terms of procedure cost, gas central heating boiler > coal boiler > biomass central heating boiler. The gas rate varies in various locations, more than biomass and also coal. The cost of biomass as well as coal are comparable, yet as coal boilers have lower efficiency, the operation expense is greater than biomass boiler.



Atmosphere result.

In terms of environmental protection, gas central heating boiler > biomass boiler > coal central heating boiler. Gas boilers take on gas as fuel, biomass boilers embrace biomass pellets or briquettes. Coal boilers create the highest possible pollution, including SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass central heating boilers arere environmental-friendly than coals. It only create C, H unstable gases, as well as little ash deposits.



Application area.

Coal boilers have actually been restricted in lots of cities, or need to be furnished with desulfurizer. Gas supply is not uniform in various locations. Some regions don't have gas readily available, so biomass boilers become their ideal selection.




In conclusion, to meet the atmosphere requirement, gas central heating boilers and biomass central heating boilers are feasible. Gas central heating boilers have the least discharge, however the price is the highest possible. Biomass central heating boilers have low cost and broad application, and also the pollution exhaust is reduced. So it has been preferred in several locations.
