Contrast biomass fuel with coal and gas<br>
Compare biomass fuel with coal


The burning efficiency of biomass fuel is comparable with tool coal, however it have such benefits over coal:




The calorific worth of biomass pellets is 10% lower than medium coal. Yet biomass pellets can burn out, while coals have 10-15% combustible part left in the coal slag. So in actual usage, their calorific worth coincide.

Biomass pellets are easier to spark than coals, which can reduce the starting time largely.

The solid discharge of biomass pellets is less than coal. It can minimize the slag discharge fee and air contamination. The strong exhaust of biomass pellets are virtually ash, making up 0.4% ~ 7.0% of the complete weight, while the strong exhaust of coal are ash, alkali, and also residual coal, making up 25% -40% of the total weight.

Coal's toxin emission as well as rust to the central heating boiler is even more severe than biomass pellets. Coal smoke includes a lot of particle carbons, poisonous SO2, carbon monoxide and also other rust gas Biomass pellets is primarily composed of C-H organic matters, the gas emission is mostly C-H unpredictable gas, with little SO2 or carbon monoxide discharge. Biomass fuel is know as clean fuel. It can considerably decrease the air contamination and carbon discharge.

Fostering of biomass fuel in boilers can conserve time and expense than coals. A 0.5 t central heating boiler can conserve 10% fuel expense and also 16% time with biomass pellets than coal.



Contrast biomass pellets and also natural gas.

Price of biomass pellets and also gas in boilers

Allow's take a 1 lot boiler as an example. Mean it require 600,000 calories for 1 hr. I work out the called for amount of gas and biomass pellets. By multiplying their system cost, we can exercise the complete expense As the type show, biomass pellets set you back a lot lower than natural gas.



Kcal/kg pricerequired quantitytotal expense.

natural 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 energy is the chemical type of solar energy. It consists of 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 yearly international energy consumption, but just 3% of them are made use of. As long as there is sunlight, the biomass energy will never ever run out.



In some rural areas, gas is not readily available. Meanwhile, with more manufacturing facilities change coal-fired boilers into gas boiler, the cost of gas is going to rise. By comparison, biomass power is rich in backwoods. They are easy to get and refine, which do not take much expense.



The ash deposits of timber pellets after shedding has minerals and also carbon. It can be utilized as fertilizer on farm and also in garden. You can collect the ash residues from biomass boilers for future usage.



Comparison of biomass boiler, gas central heating boiler, and also coal central heating boiler.

Under the setting protection stress, coal central heating boilers are limited in numerous cities. Several factories have switched over to biomass boiler or gas boiler. Here I 'd like to compare the 3 central heating boilers and also identify which is the most effective.



Initial financial investment.

In term of the central heating boilers with the same ability, gas boilers call for the highest possible cost, after that comes biomass boiler, as well as coal boiler for the last.



Operation cost.

In terms of operation expense, gas boiler > coal central heating boiler > biomass central heating boiler. The gas cost differs in various locations, greater than biomass and also coal. The rate of biomass as well as coal are comparable, but as coal central heating boilers have reduced effectiveness, the operation price is higher than biomass central heating boiler.



Environment effect.

In regards to environmental management, gas central heating boiler > biomass central heating boiler > coal boiler. Gas boilers adopt gas as fuel, biomass central heating boilers adopt biomass pellets or briquettes. Coal boilers create the highest possible pollution, consisting of SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass boilers arere environmental-friendly than coals. It only produce C, H volatile gases, and little ash deposits.



Application location.

Coal central heating boilers have been limited in many cities, or require to be furnished with desulfurizer. animal feed pellet machine for sale is not uniform in different locations. Some regions don't have gas available, so biomass boilers become their finest option.



Finally, to satisfy the environment demand, gas boilers as well as biomass central heating boilers are viable. Gas central heating boilers have the least exhaust, however the price is the highest. Biomass central heating boilers have inexpensive and broad application, and also the contamination emission is reduced. So it has actually been preferred in lots of locations.
