The burning efficiency of biomass fuel is comparable with medium coal, yet it have such benefits over coal:
The calorific worth of biomass pellets is 10% less than tool coal. Yet biomass pellets can wear out, while coals have 10-15% flammable part left in the coal slag. So in real usage, their calorific value are the same.
Biomass pellets are much easier to fire up than coals, which can reduce the starting time greatly.
The strong discharge of biomass pellets is lower than coal. It can reduce the slag discharge charge and air pollution. The strong discharge of biomass pellets are almost ash, making up 0.4% ~ 7.0% of the complete weight, while the strong emission of coal are ash, alkali, and residual coal, representing 25% -40% of the overall weight.
Coal's contaminant discharge and corrosion to the boiler is far more significant than biomass pellets. Coal smoke contains a lot of bit carbons, poisonous SO2, CO and other corrosion gas Biomass pellets is primarily composed of C-H organic matters, the gas exhaust is primarily C-H unstable gas, with little SO2 or CO discharge. Biomass fuel is referred to as clean fuel.small fish feed machine pricecan considerably lower the air pollution and also carbon emission.
Fostering of biomass fuel in boilers can save time and also price than coals. A 0.5 t boiler can conserve 10% fuel expense and 16% time with biomass pellets than coal.
Compare biomass pellets and also natural gas.
Price of biomass pellets and gas in boilers
Allow's take a 1 ton central heating boiler as an example. Mean it need 600,000 calories for 1 hour. I exercise the needed quantity of gas as well as biomass pellets. By increasing their device price, we can work out the total expense As the kind show, biomass pellets cost a lot lower than natural gas.

natural gas 9000 3.6/ m366m3 238.

Natural gas is a non-renewable source, like coal as well as oil. Biomass energy is the chemical form of solar power. It includes timber, forestry waste, crop waste, water plant, pet dung, plant wastes. Annually, the biomass generated by photosynthesis depends on 173 billion bunch, equal to 10-20 times the annual global energy consumption, however only 3% of them are utilized. As long as there is sunshine, the biomass energy will never run out.
In some backwoods, gas is not available. Meanwhile, with even more manufacturing facilities change coal-fired boilers into gas boiler, the rate of natural gas is mosting likely to rise. By comparison, biomass energy is abundant in rural areas. They are simple to acquire and process, which don't take much price.
The ash residues of timber pellets after melting contains minerals and carbon. It can be made use of as fertilizer on ranch and in yard. You can gather the ash deposits from biomass central heating boilers for future use.
Contrast of biomass central heating boiler, gas central heating boiler, as well as coal boiler.
Under the atmosphere security stress, coal central heating boilers are limited in several cities. Numerous manufacturing facilities have actually switched to biomass boiler or gas boiler. Below I want to contrast the 3 central heating boilers and find out which is the most effective.
First financial investment.
In term of the central heating boilers with the exact same capability, gas boilers call for the highest cost, after that comes biomass central heating boiler, and coal central heating boiler for the last.
Procedure price.
In terms of procedure cost, gas central heating boiler > coal central heating boiler > biomass boiler. The gas price differs in various areas, more than biomass and also coal. The rate of biomass and also coal are similar, yet as coal boilers have lower efficiency, the operation price is greater than biomass boiler.
Atmosphere effect.
In terms of environmental protection, gas boiler > biomass central heating boiler > coal central heating boiler. Gas central heating boilers take on natural gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal boilers generate the highest contamination, consisting of SO2, CO, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It just create C, H unpredictable gases, as well as little ash deposits.
Application location.
Coal boilers have actually been restricted in numerous cities, or require to be geared up with desulfurizer.richi pellet machineis not uniform in various areas. Some regions don't have gas offered, so biomass central heating boilers become their finest choice.
Finally, to fulfill the atmosphere demand, gas boilers and biomass central heating boilers are practical. Gas central heating boilers have the least emission, but the price is the highest possible. Biomass central heating boilers have low cost and also wide application, and also the pollution discharge is low. So it has actually been popular in numerous locations.
