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. But biomass pellets can burn out, while coals have 10-15% flammable part left in the coal slag. So in actual usage, their calorific value coincide.

Biomass pellets are much easier to fire up than coals, which can shorten the starting time greatly.

The strong discharge of biomass pellets is lower than coal. It can lower the slag discharge cost and air pollution. The solid emission of biomass pellets are nearly ash, accounting for 0.4% ~ 7.0% of the total weight, while the solid discharge of coal are ash, alkali, as well as residual coal, accounting for 25% -40% of the total weight.

Coal's toxin exhaust and deterioration to the boiler is far more significant than biomass pellets. Coal smoke contains a lot of fragment carbons, toxic SO2, carbon monoxide and also other deterioration gas Biomass pellets is mainly composed of C-H organic matters, the gas emission is generally C-H unstable gas, with little SO2 or carbon monoxide exhaust. Biomass fuel is referred to as tidy fuel. floating fish feed machine price can considerably decrease the air pollution as well as carbon emission.

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



Compare biomass pellets and also natural gas.

Cost of biomass pellets and gas in central heating boilers

Let's take a 1 ton central heating boiler for example. Suppose it need 600,000 calories for 1 hour. I work out the called for amount of gas as well as biomass pellets. By increasing their unit price, we can exercise the overall price As the type show, biomass pellets cost a lot lower than natural gas.



Kcal/kg pricerequired quantitytotal expense.

gas 9000 ￥ 3.6/ m366m3 ￥ 238.

biomass pellets4200 ￥ 900/t 140kg ￥ 126.



Natural gas is a non-renewable resource, like coal and also oil. Biomass power is the chemical kind of solar power. It consists of wood, forestry waste, crop waste, water plant, pet dung, plant wastes. Every year, the biomass produced by photosynthesis is up to 173 billion heap, equal to 10-20 times the yearly worldwide energy consumption, but just 3% of them are used. As long as there is sunshine, the biomass energy will never ever go out.



In some backwoods, natural gas is not offered. On the other hand, with more manufacturing facilities change coal-fired central heating boilers into gas boiler, the rate of gas is going to rise. By comparison, biomass power is abundant in rural areas. They are simple to obtain and also refine, which don't take much expense.



The ash deposits of timber pellets after shedding has minerals and carbon. It can be made use of as fertilizer on farm and in garden. You can accumulate the ash residues from biomass central heating boilers for future usage.



Contrast of biomass boiler, gas boiler, and coal boiler.

Under the setting protection pressure, coal central heating boilers are limited in several cities. Several factories have switched over to biomass boiler or gas boiler. Below I want to contrast the 3 boilers and find out which is the most effective.



Initial investment.

In term of the boilers with the exact same capability, gas boilers call for the greatest cost, then comes biomass central heating boiler, and also coal central heating boiler for the last.




Operation cost.

In regards to procedure price, gas boiler > coal central heating boiler > biomass boiler. The gas rate differs in various areas, greater than biomass and coal. The price of biomass and also coal are comparable, however as coal boilers have lower efficiency, the procedure price is more than biomass boiler.



Setting impact.

In terms of environmental management, gas central heating boiler > biomass central heating boiler > coal boiler. Gas central heating boilers embrace gas as fuel, biomass central heating boilers take on biomass pellets or briquettes. Coal central heating boilers produce the greatest contamination, including SO2, CARBON MONOXIDE, ash, alkali, etc. Biomass central heating boilers arere environmental-friendly than coals. It just create C, H volatile gases, as well as little ash residues.



Application location.

Coal boilers have been limited in many cities, or require to be geared up with desulfurizer. Gas supply is not uniform in various areas. Some regions don't have gas available, so biomass boilers become their best selection.



To conclude, to meet the setting need, gas central heating boilers as well as biomass boilers are viable. wood pellet maker for sale have the least discharge, yet the price is the greatest. Biomass boilers have inexpensive and vast application, and the air pollution discharge is low. So it has been prominent in several areas.
