The burning efficiency of biomass fuel is similar with tool coal, yet it have such advantages over coal:
The calorific value of biomass pellets is 10% lower than tool coal. However biomass pellets can stress out, while coals have 10-15% flammable component left in the coal slag. So in actual usage, their calorific worth are the same.
Biomass pellets are simpler to fire up than coals, which can reduce the starting time mainly.
The solid discharge of biomass pellets is less than coal. It can minimize the slag discharge charge as well as air contamination. The solid exhaust of biomass pellets are almost ash, accounting for 0.4% ~ 7.0% of the total weight, while the solid exhaust of coal are ash, antacids, as well as residual coal, representing 25% -40% of the total weight.
Coal's toxin emission and also corrosion to the boiler is far more severe than biomass pellets. Coal smoke includes a lot of fragment carbons, toxic SO2, CO and also other corrosion gas Biomass pellets is generally made up of C-H organic matters, the gas discharge is generally C-H unstable gas, with little SO2 or CO emission. Biomass fuel is referred to as tidy fuel. It can substantially decrease the air pollution as well as carbon discharge.
Adoption of biomass fuel in central heating boilers can conserve time and also price than coals. A 0.5 t boiler can conserve 10% fuel expense as well as 16% time with biomass pellets than coal.
Compare biomass pellets and natural gas.
Expense of biomass pellets as well as gas in boilers
Let's take a 1 ton central heating boiler for example. Suppose it require 600,000 calories for 1 hour. I work out the required amount of gas and also biomass pellets. By increasing their unit price, we can exercise the overall price As the form show, biomass pellets set you back much less than gas.
Kcal/kg pricerequired quantitytotal cost.
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 kind of solar energy. It includes timber, forestry waste, plant waste, water plant, animal dung, plant wastes. Yearly, the biomass generated by photosynthesis depends on 173 billion load, equal to 10-20 times the annual worldwide energy usage, however only 3% of them are utilized. As long as there is sunlight, the biomass power will never run out.
In some backwoods, natural gas is not readily available. On the other hand, with even more factories transform coal-fired central heating boilers right into gas boiler, the cost of natural gas is mosting likely to rise up. Bypelletizer for sale , biomass energy is rich in rural areas. They are very easy to acquire as well as refine, which don't take much expense.
The ash residues of timber pellets after melting consists of minerals and also carbon. It can be utilized as fertilizer on farm and also in yard. You can collect the ash residues from biomass central heating boilers for future usage.
Comparison of biomass central heating boiler, gas boiler, as well as coal central heating boiler.
Under the setting defense pressure, coal boilers are limited in many cities. Lots of factories have actually switched over to biomass boiler or gas boiler. Below I 'd like to compare the 3 central heating boilers as well as identify which is the very best.
Preliminary investment.
In term of the central heating boilers with the very same ability, gas boilers need the highest expense, after that comes biomass boiler, as well as coal boiler for the last.
Operation cost.
In terms of procedure price, gas central heating boiler > coal central heating boiler > biomass boiler. The gas rate differs in different areas, greater than biomass and also coal. The price of biomass and also coal are similar, however as coal central heating boilers have lower effectiveness, the operation expense is greater than biomass boiler.
Setting impact.
In terms of environmental management, gas boiler > biomass central heating boiler > coal central heating boiler. Gas central heating boilers embrace natural gas as fuel, biomass central heating boilers embrace biomass pellets or briquettes. Coal central heating boilers produce the highest contamination, including SO2, CO, ash, antacids, and so on. Biomass boilers arere environmental-friendly than coals. It just create C, H unstable gases, and also little ash residues.
Application location.
Coal boilers have actually been restricted in numerous cities, or require to be outfitted with desulfurizer.pellet mill for feedis not uniform in various areas. Some areas don't have gas readily available, so biomass central heating boilers become their ideal selection.
In conclusion, to satisfy the environment demand, gas central heating boilers and also biomass boilers are feasible.kl230 animal feedhave the least emission, but the cost is the highest. Biomass boilers have low cost as well as vast application, as well as the pollution emission is low. So it has been popular in many areas.
