Compare biomass fuel with coal and natural gas
Compare biomass fuel with coal and also natural gas
Contrast biomass fuel with coal
The burning performance of biomass fuel is comparable with tool coal, yet it have such benefits over coal:

The calorific worth of biomass pellets is 10% less than tool coal. But biomass pellets can stress out, while coals have 10-15% combustible element left in the coal slag. So in real usage, their calorific value coincide.
Biomass pellets are much easier to stir up than coals, which can shorten the starting time largely.

The solid discharge of biomass pellets is lower than coal. It can lower the slag discharge cost as well as air contamination. The solid emission of biomass pellets are nearly 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 pollutant emission as well as corrosion to the central heating boiler is far more significant than biomass pellets. small poultry feed making machine consists of a lot of bit carbons, hazardous SO2, CO and also other corrosion gas Biomass pellets is generally composed of C-H organic matters, the gas exhaust is primarily C-H volatile gas, with little SO2 or carbon monoxide discharge. Biomass fuel is referred to as clean fuel. It can considerably decrease the air pollution and carbon emission.
Adoption of biomass fuel in central heating boilers can conserve time as well as price than coals. A 0.5 t boiler can save 10% fuel cost as well as 16% time with biomass pellets than coal.

Compare biomass pellets and also natural gas.
Cost of biomass pellets and natural gas in central heating boilers
Let's take a 1 ton central heating boiler for instance. Expect it need 600,000 calories for 1 hour. I work out the called for quantity of gas and biomass pellets. By multiplying their device cost, we can work out the overall expense As the form program, biomass pellets cost a lot lower than gas.


Kcal/kg pricerequired quantitytotal expense.
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 energy is the chemical type of solar energy. It consists of wood, forestry waste, plant waste, water plant, pet dung, plant wastes. Each year, the biomass created by photosynthesis is up to 173 billion ton, equal to 10-20 times the yearly international power consumption, yet just 3% of them are utilized. As long as there is sunshine, the biomass power will certainly never ever go out.

In some backwoods, gas is not available. On the other hand, with even more manufacturing facilities change coal-fired central heating boilers into natural gas boiler, the cost of natural gas is going to rise up. By contrast, biomass power is abundant in rural areas. They are easy to acquire and also refine, which do not take much expense.

The ash residues of wood pellets after burning consists of minerals and also carbon. It can be utilized as plant food on ranch and also in garden. You can gather the ash deposits from biomass boilers for future usage.

Contrast of biomass central heating boiler, gas boiler, and coal boiler.
Under the environment defense pressure, coal central heating boilers are restricted in many cities. Many manufacturing facilities have switched over to biomass boiler or gas boiler. Below I 'd like to contrast the 3 boilers and also determine which is the best.

Initial financial investment.
In regard to the central heating boilers with the exact same capacity, gas central heating boilers need the highest expense, then comes biomass boiler, as well as coal central heating boiler for the last.

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

Environment impact.
In terms of environmental protection, gas central heating boiler > biomass boiler > coal central heating boiler. Gas boilers take on gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal boilers create the highest contamination, including SO2, CO, ash, alkali, etc. Biomass central heating boilers arere environmental-friendly than coals. It just generate C, H unpredictable gases, and also little ash deposits.

Richi machine .
Coal boilers have actually been limited in many cities, or need to be equipped with desulfurizer. Gas supply is not uniform in various areas. Some regions don't have gas available, so biomass central heating boilers become their best choice.

To conclude, to fulfill the setting requirement, gas central heating boilers and biomass boilers are feasible. Gas central heating boilers have the least exhaust, yet the cost is the highest. sites have affordable and vast application, and also the pollution discharge is low. So it has actually been popular in numerous areas.
