Why is biomass a far better option to gas?<br>
Competition between biomass gas as well as natural gas
In recent times, the application of biomass fuel is boosting. In lots of locations, there emerge competitors between biomass gas as well as natural gas. In this flow, I will take central heating boiler burning as an example, and also contrast the devices expense, operation cost and environment impact of biomass boiler as well as gas boiler.
This blog site contrasts the financial and also ecological result of biomass fuel and also natural gas. The equipment price of biomass boiler is more than that of natural gas central heating boiler. Taking into consideration the high cost of gas, the annual operating expense (consisting of the price of gas, electrical energy, labors and also maintenance) of natural gas is higher than biomass central heating boiler.
When using biomass gas, it requires to be furnished with dirt collector, sulfur and nitrate removing tool to make certain the contaminant exhaust satisfy the standard. When it comes to natural gas central heating boiler, it takes on low-nitrogen burning innovation or denitrification gadget to guarantee the NOx exhaust satisfy the standard.
Evaluation of biomass energy
Biomass power is solar energy deposited in biomass materials in the form of chemical energy. It originates from the photosynthesis of eco-friendly plants. It has the form of strong, liquid and gas. Biomass energy is known as a renewable resource.
According to the different resources, the biomass fuels can be identified into 6 kinds: crop straw, forestry waste, animal dung, water plants, energy plants, life rubbish.
Biomass power has the complying with advantages
Affordable, vast circulation, huge volume, renewability, storable, easy to use.
Biomass power likewise has some negative aspects:
Low energy density, not appropriate for long-distance transport. To make certain the biomass fuel supply, it requires large area for storage space, which brings management problem.
Plant straw has broad circulation, but it is affected by areas, seasons, weather conditions and also other factors. The supply is not stable. Besides, the calorific value differs a great deal. Some are not appropriate for central heating boilers.
Various type of biomass gas have various burning results, which may create slagging as well as leaves way too much ash. The alkaline web content in the ash will certainly impede the continual job of biomass central heating boiler as well as trigger rust.
Biomass fuels are easy to obtain damp. The wetness material have terrific impact on the combustion temperature level. Over-high wetness web content will make the biomass fuel incapable to burn.

The labor price is 144,000 annually.
Annual upkeep price.
Biomass boiler generally has lots of supporting machinery. Their failing price is more than gas boiler. The annual maintenance expense is in percentage to the equipment expense. If the maintenance cost is 2.5% of the devices cost, then it is ￥ 6100 each year.
By computation, the yearly running cost of biomass boiler is ￥ 2,957,400.
Gas boiler.
Yearly fuel price.
For example.
The heat effectiveness of biomass boiler is 90%.
The calorific value of natural gas is 35.58 MJ/kg.
The price of gas is ￥ 3.1/ m3.
A gas central heating boiler can eat 315m3 gas every hr.
A gas boiler runs 10 hours everyday, 300 days every year.
By computation, the annual gas expense is ￥ 2,929,500.
Annual electrical fee.
The power of the burner is 7.5 kw.
The power of water pump as well as various other power application devices is 7kw.
So the complete electrical power of the biomass central heating boiler is 14.5 kw.
The electricity rate is ￥ 1.0/ kwh.
The working time is 10 hours each day, 300 days each year.
So the annual electrical power price is ￥ 43500.
Yearly labor cost.
The work has 2 shifts a day.
As the gas central heating boiler has higher automation, and the procedure is simple, it calls for only 1 fire fighter.
The wage is ￥ 3000 monthly, so the annual labor expense is ￥ 72000.
Annual maintenance expense.
The upkeep job of a gas central heating boiler is not much, the price is low.
Intend the maintenance expense is 1% of the devices cost, then it is ￥ 2100 every year.
By computation, the annual running cost of a biomass boiler is ￥ 3,047,100.
Verdict.
In terms of the equipment expense, biomass central heating boiler is more than natural gas boiler. In terms of the yearly running cost, as natural gas boiler has higher automation level, needs much less power intake tool, and less upkeep, the electric cost, labor price as well as maintenance expense is less than that of biomass boiler. However thinking about the high cost of gas, the total operation expense of gas boiler is higher than that of biomass central heating boiler.
Ecological result.
Biomass fuel.
Scientist determined the exhaust of smoke, SO2 and also NOx in 2 biomass boiler.
These 2 central heating boilers has similar dissipation capacity. Both of them are not furnished with sulfur as well as nitrate getting rid of gadget. However the first one is furnished with a bag-type dust collection agency, and the 2nd one is furnished with a film-type dust collector.
The boiler furnished with film-type dirt collection agency can lower the ash discharge efficiently. In terms of SO2 exhaust, the timber pellets can fulfill the stipulated criterion also without sulfur eliminating tool. When it comes to NOx emission, the timber pellets can satisfy the standard in central heating boilers equipped with film-type dust collection agency.
Natural gas.
Natural gas is a premium quality as well as clean gas fuel. The fostering of gas in the central heating boiler can lower the air contamination remarkably. The ash, sulfur and also nitrogen material in the natural gas is low. small wood pellet making machine of gas includes little SOx, which a meet stipulated criterion. But the NOx exhaust is still an issue. Researched found the NOx emission of natural gas central heating boiler is 125mg/m3, as well as 25% of them is more than 150mg/m3.
Conclusion.
According to the analysis above, the type of biomass gas has wonderful impact on the toxin emission. Wood pellets has less SO2 discharge than straw pellets. The biomass boiler with film-type dirt enthusiast has better ash eliminating impact than bag-type dirt collector.
The NOx emission is past standard in biomass boilers without sulfur or nitrate eliminating tool, whatever timber pellets or straw pellets. As a result, it is advise to outfit reliable dust enthusiast, as well as sulfur and nitrate eliminating tool.
Natural gas has advantages in reducing smoke and SO2 exhaust. However with the enhancing emission criterion, more gas central heating boilers will certainly take on low-nitrogen burning innovation as well as nitrate eliminating gadget.
The corresponding benefits of gas and also biomass fuel.
The price of biomass central heating boiler is more than natural gas. Their operating expense is similar thinking about the rise of natural gas rate. Besides, the gas boiler is less complicated to manage, as well as it doesn't take much floor area or fuel storage room.
The price of natural gas is under federal government control, so it will not change greatly. The natural gas supply can be ensured when the gas central heating boiler is in usage. Biomass pellets supply is limited by seasons. The price as well as supply is unsteady, which normally occupies huge warehouse room.
In regards to environmental protection, biomass boilers have to be furnished with dust enthusiast, sulfur as well as nitrate getting rid of device to ensure the smoke, SO2 and also NOx exhaust meet the standard. However gas central heating boilers doesn't need dust collector or desulfurizer, but it need to adopt low-nitrogen burning innovation or nitrate removing device to reduce the NOx exhaust. Besides, the natural gas boiler does not need dirt cleansing procedure.
On the other side, biomass fuel is eco-friendly. It is solar power deposited in plants by photosynthesis. As data reveal, the biomass energy generated by photosynthesis is 173 billion load, but only 3% of them are made use of. Besides, flat die pellet machine is carbon neutral, which suggests the CO2 intake in its growth amounts to the emission in biomass gas burning.
Fluidized-bed combustion is a technology based on gas-solid fluidized state. It has good adaptability to biomass gas, the contaminant gas emission is reduced. By adding desulfurizer to the fluidized bed, it can remove the sulfur straight, and lower the SO2 material in the smoke dramatically.
Nowadays, the fluidized bed can be made use of for the burning of various sort of gas, suitable for the co-firing of biomass and coals. The type of gas and also their percentage is flexible, so you can choose them according the rate to lower your cost.
The high cost of gas is a problem. And the price variation between summer as well as winter is buckling down. Biomass is an outstanding substitute for typical gas. To fulfill the ecological requirement as well as attain higher cost-effective benefits, it is very important to improve the application innovation of biomass fuel, as well as boost the percentage of biomass in energy mix.
