Compare biomass fuel with coal
The burning performance of biomass fuel is similar with medium coal, yet it have such benefits over coal:

The calorific worth of biomass pellets is 10% lower than medium coal. However biomass pellets can burn out, while coals have 10-15% flammable component left in the coal slag. So in actual use, their calorific worth are the same.
Biomass pellets are simpler to spark than coals, which can reduce the starting time largely.
The solid discharge of biomass pellets is lower than coal. It can lower the slag discharge fee and air pollution. The solid emission of biomass pellets are virtually ash, accounting for 0.4% ~ 7.0% of the complete weight, while the solid emission of coal are ash, alkali, and residual coal, representing 25% -40% of the total weight.
Coal's pollutant discharge and also rust to the central heating boiler is far more significant than biomass pellets. Coal smoke consists of a lot of particle carbons, harmful SO2, carbon monoxide as well as various other rust gas Biomass pellets is generally composed of C-H raw materials, the gas exhaust is mainly C-H unstable gas, with little SO2 or carbon monoxide emission. Biomass fuel is referred to as clean fuel. It can greatly minimize the air contamination and also carbon exhaust.
Fostering of biomass fuel in boilers can conserve time and also expense than coals. A 0.5 t boiler can conserve 10% fuel cost and also 16% time with biomass pellets than coal.

Contrast biomass pellets and also gas.
Cost of biomass pellets and also natural gas in boilers
Let's take a 1 ton boiler as an example. Suppose it require 600,000 calories for 1 hour. I exercise the needed quantity of natural gas and also biomass pellets. By increasing their device cost, we can exercise the overall expense As the kind program, biomass pellets cost much less than 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 oil. Biomass energy is the chemical type of solar power. It consists of timber, forestry waste, crop waste, water plant, pet dung, plant wastes. Each year, the biomass produced by photosynthesis depends on 173 billion lot, equal to 10-20 times the yearly international power consumption, but just 3% of them are utilized. As long as there is sunshine, the biomass power will never ever run out.

In some backwoods, natural gas is not readily available. At the same time, with more factories change coal-fired boilers right into natural gas central heating boiler, the cost of natural gas is mosting likely to rise. By contrast, biomass power is rich in backwoods. They are easy to get as well as refine, which don't take much price.

The ash deposits of timber pellets after shedding has minerals as well as carbon. floating feed machine can be utilized as fertilizer on farm and also in yard. You can gather the ash residues from biomass central heating boilers for future usage.

Contrast of biomass boiler, gas boiler, as well as coal central heating boiler.
Under small electric fish feed extruder machine price , coal central heating boilers are limited in lots of cities. Numerous factories have actually switched over to biomass boiler or gas central heating boiler. Below I wish to contrast the 3 central heating boilers as well as determine which is the most effective.

Initial financial investment.
In term of the boilers with the exact same capacity, gas central heating boilers call for the highest expense, then comes biomass central heating boiler, and also coal boiler for the last.

Procedure price.
In terms of operation expense, gas boiler > coal central heating boiler > biomass central heating boiler. The gas price differs in various areas, more than biomass and coal. The price of biomass as well as coal are comparable, yet as coal boilers have reduced efficiency, the operation expense is higher than biomass central heating boiler.

In regards to environmental protection, gas central heating boiler > biomass boiler > coal boiler. Gas central heating boilers take on gas as fuel, biomass boilers take on biomass pellets or briquettes. Coal boilers produce the greatest pollution, consisting of SO2, CARBON MONOXIDE, ash, alkali, and so on. Biomass boilers arere environmental-friendly than coals. It only create C, H unpredictable gases, and little ash residues.

Application location.
Coal central heating boilers have been restricted in many cities, or require to be geared up with desulfurizer. Gas supply is not uniform in various locations. Some regions don't have gas available, so biomass central heating boilers become their ideal choice.


Finally, to fulfill the environment demand, gas boilers and biomass boilers are sensible. Gas central heating boilers have the least exhaust, however the price is the highest. Biomass central heating boilers have affordable and broad application, and also the air pollution exhaust is reduced. So it has been popular in several locations.
