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 medium coal. But biomass pellets can wear out, while coals have 10-15% combustible component left in the coal slag. So in actual usage, their calorific worth coincide.

Biomass pellets are less complicated to stir up than coals, which can shorten the starting time mainly.

The strong discharge of biomass pellets is lower than coal. It can minimize the slag discharge cost and air pollution. 2nd hand pellet machine of biomass pellets are nearly ash, representing 0.4% ~ 7.0% of the complete weight, while the strong discharge of coal are ash, alkali, as well as residual coal, making up 25% -40% of the overall weight.

Coal's toxin emission as well as rust to the central heating boiler is even more serious than biomass pellets. Coal smoke consists of a great deal of particle carbons, harmful SO2, CO as well as other corrosion gas Biomass pellets is primarily composed of C-H raw materials, the gas discharge is generally C-H volatile gas, with little SO2 or carbon monoxide discharge. Biomass fuel is know as clean fuel. It can substantially minimize the air contamination as well as carbon discharge.

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



Compare biomass pellets and gas.

Price of biomass pellets and also natural gas in boilers

Allow's take a 1 lot boiler as an example. Mean it require 600,000 calories for 1 hour. pellet maker for feed exercise the called for amount of natural gas as well as biomass pellets. By multiplying their unit rate, we can work out the total expense As the form program, biomass pellets cost much lower than natural gas.

Natural gas is a non-renewable source, like coal as well as oil. Biomass energy is the chemical kind of solar power. It includes timber, forestry waste, crop waste, marine plant, animal dung, plant wastes. Yearly, the biomass generated by photosynthesis is up to 173 billion ton, equal to 10-20 times the annual international energy usage, but just 3% of them are used. As long as there is sunlight, the biomass power will certainly never ever run out.



In some rural areas, natural gas is not available. On the other hand, with even more manufacturing facilities transform coal-fired central heating boilers into natural gas central heating boiler, the cost of gas is mosting likely to rise. By comparison, biomass power is rich in backwoods. They are very easy to acquire as well as refine, which do not take much cost.



The ash residues of wood pellets after shedding has minerals as well as carbon. It can be used as fertilizer on farm and also in garden. You can accumulate the ash residues from biomass boilers for future use.



Contrast of biomass boiler, gas central heating boiler, as well as coal central heating boiler.

Under the setting protection stress, coal boilers are limited in several cities. Numerous factories have actually switched to biomass central heating boiler or gas central heating boiler. Here I want to contrast the 3 central heating boilers as well as identify which is the most effective.



Initial investment.

In regard to the central heating boilers with the exact same ability, gas boilers need the highest possible cost, after that comes biomass central heating boiler, and also coal boiler for the last.



Operation cost.

In terms of procedure expense, gas boiler > coal boiler > biomass boiler. The gas rate differs in different areas, more than biomass and also coal. The rate of biomass and also coal are comparable, but as coal boilers have reduced efficiency, the procedure cost is more than biomass central heating boiler.



Environment impact.

In terms of environmental management, gas central heating boiler > biomass boiler > coal central heating boiler. Gas boilers adopt natural gas as fuel, biomass central heating boilers embrace biomass pellets or briquettes. Coal boilers generate the highest contamination, consisting of SO2, CARBON MONOXIDE, ash, antacids, and so on. Biomass boilers arere environmental-friendly than coals. It only generate C, H volatile gases, as well as little ash residues.



Application area.

Coal central heating boilers have been limited in many cities, or need to be outfitted with desulfurizer. Natural gas supply is not uniform in various areas. Some regions don't have natural gas available, so biomass boilers become their best selection.



In conclusion, to fulfill the environment demand, gas central heating boilers and biomass boilers are sensible. Gas boilers have the least discharge, yet the expense is the highest possible. Biomass boilers have low cost as well as broad application, as well as the pollution exhaust is low. So it has been popular in lots of locations.
