The burning performance of biomass fuel is similar with medium coal, yet it have such advantages over coal:
The calorific value of biomass pellets is 10% lower than medium coal. However biomass pellets can wear out, while coals have 10-15% combustible part 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 mainly.
The solid discharge of biomass pellets is less than coal. It can decrease the slag discharge charge as well as air contamination. The solid exhaust of biomass pellets are almost ash, making up 0.4% ~ 7.0% of the overall weight, while the solid emission of coal are ash, antacids, and also residual coal, accounting for 25% -40% of the overall weight.
Coal's toxin emission as well as rust to the central heating boiler is far more serious than biomass pellets. Coal smoke contains a great deal of fragment carbons, poisonous SO2, CO as well as various other corrosion gas Biomass pellets is mostly made up of C-H raw materials, the gas discharge is mostly C-H unstable gas, with little SO2 or CO emission. Biomass fuel is know as tidy fuel. It can greatly minimize the air contamination and also carbon emission.
Fostering of biomass fuel in boilers can conserve time as well as cost than coals. A 0.5 t boiler can conserve 10% fuel price as well as 16% time with biomass pellets than coal.
Contrast biomass pellets and gas.
Cost of biomass pellets and also gas in boilers
Let's take a 1 load boiler for example. Expect it need 600,000 calories for 1 hour. manual fish feed making machine work out the needed quantity of gas and biomass pellets. By multiplying their system cost, we can exercise the complete cost As the type program, biomass pellets cost a lot lower than natural gas.
Kcal/kg pricerequired quantitytotal cost.
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 type of solar power. It consists of wood, forestry waste, plant waste, aquatic plant, animal dung, plant wastes. Each year, the biomass produced by photosynthesis is up to 173 billion lot, equal to 10-20 times the annual international power consumption, but only 3% of them are utilized. As long as there is sunlight, the biomass power will never go out.
In some rural areas, natural gas is not offered. On the other hand, with even more factories change coal-fired central heating boilers right into natural gas central heating boiler, the price of gas is mosting likely to rise. By comparison, biomass energy is rich in backwoods. They are simple to acquire and process, which don't take much price.
The ash deposits of wood pellets after burning contains minerals and also carbon. It can be utilized as fertilizer on ranch and also in garden. You can accumulate the ash deposits from biomass central heating boilers for future usage.
Comparison of biomass central heating boiler, gas central heating boiler, as well as coal central heating boiler.
Under the setting defense pressure, coal boilers are restricted in many cities. Many manufacturing facilities have actually switched to biomass boiler or gas central heating boiler. \animal feed pellet machine\ wish to compare the 3 central heating boilers as well as determine which is the very best.
First financial investment.
In term of the central heating boilers with the very same ability, gas central heating boilers require the highest possible price, after that comes biomass central heating boiler, and also coal central heating boiler for the last.
Procedure expense.
In terms of operation price, gas central heating boiler > coal boiler > biomass central heating boiler. The gas rate differs in different areas, higher than biomass and also coal. The cost of biomass and coal are comparable, but as coal central heating boilers have reduced performance, the procedure cost is more than biomass central heating boiler.
Setting result.
In terms of environmental protection, gas central heating boiler > biomass boiler > coal central heating boiler. Gas boilers embrace natural gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal central heating boilers generate the highest contamination, including SO2, CARBON MONOXIDE, ash, antacids, etc. Biomass central heating boilers arere environmental-friendly than coals. It only create C, H unpredictable gases, and little ash residues.
Application area.
Coal central heating boilers have been restricted in many cities, or require to be furnished with desulfurizer. Gas supply is not uniform in different locations. Some regions do not have gas offered, so biomass central heating boilers become their best choice.
In conclusion, to meet the atmosphere demand, gas boilers as well as biomass boilers are viable. Gas central heating boilers have the least exhaust, but the cost is the highest possible. Biomass central heating boilers have inexpensive and broad application, as well as the contamination discharge is low. So it has actually been popular in several areas.
