Contrast biomass fuel with coal

The burning efficiency of biomass fuel is similar with tool coal, however it have such benefits over coal:



The calorific worth of biomass pellets is 10% less than tool coal. Yet biomass pellets can burn 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 mainly.


The strong discharge of biomass pellets is less than coal. It can minimize the slag discharge cost and air contamination. Richi machine of biomass pellets are virtually ash, accounting for 0.4% ~ 7.0% of the overall weight, while the strong exhaust of coal are ash, antacids, and recurring coal, accounting for 25% -40% of the overall weight.

Coal's toxin emission and deterioration to the central heating boiler is far more severe than biomass pellets. Coal smoke includes a great deal of particle carbons, poisonous SO2, carbon monoxide and also other deterioration gas Biomass pellets is primarily composed of C-H organic matters, the gas emission is mainly C-H unpredictable gas, with little SO2 or CO emission. Biomass fuel is know as clean fuel. It can significantly minimize the air contamination and also carbon emission.

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



Contrast biomass pellets as well as gas.

Expense of biomass pellets and natural gas in central heating boilers

Let's take a 1 bunch boiler for example. Expect it require 600,000 calories for 1 hr. I exercise the required quantity of gas and also biomass pellets. By multiplying their device price, we can exercise the overall expense As the kind program, biomass pellets set you back much lower than natural gas.



Kcal/kg pricerequired quantitytotal expense.

natural gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



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, animal dung, plant wastes. Every year, the biomass generated by photosynthesis depends on 173 billion load, equal to 10-20 times the annual international energy intake, however only 3% of them are utilized. As long as there is sunlight, the biomass energy will never run out.



In some backwoods, natural gas is not readily available. At the same time, with more manufacturing facilities change coal-fired central heating boilers into gas boiler, the price of natural gas is going to rise. By comparison, biomass energy is rich in backwoods. They are very easy to obtain and also process, which do not take much cost.



The ash residues of wood pellets after shedding consists of minerals and also carbon. It can be made use of as plant food on ranch and in garden. You can collect the ash deposits from biomass central heating boilers for future use.



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

Under the environment defense pressure, coal central heating boilers are restricted in lots of cities. Many manufacturing facilities have actually switched over to biomass central heating boiler or gas central heating boiler. Right here I want to contrast the 3 central heating boilers as well as identify which is the best.



Initial financial investment.

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



Operation cost.

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



Setting effect.

In terms of environmental protection, gas central heating boiler > biomass boiler > coal boiler. Gas central heating boilers adopt natural gas as fuel, biomass boilers embrace biomass pellets or briquettes. Coal central heating boilers create the highest contamination, including SO2, CO, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It only create C, H unpredictable gases, as well as little ash deposits.



Application area.

Coal central heating boilers have actually been restricted in many cities, or need to be geared up with desulfurizer. Natural gas supply is not uniform in different areas. Some regions do not have natural gas available, so biomass boilers become their best choice.




To conclude, to fulfill the setting need, gas boilers and also biomass boilers are sensible. fish feed machine price have the least emission, however the expense is the highest. Biomass boilers have affordable and vast application, and also the pollution discharge is low. So it has actually been popular in several areas.
