Why is biomass a far better alternative to gas?<br>
Competition in between biomass fuel and also gas

In recent years, the application of biomass gas is increasing. In numerous locations, there occur competitions in between biomass fuels as well as gas. In this passage, I will take central heating boiler burning for example, and also contrast the tools cost, operation price and also environment effect of biomass central heating boiler and also gas central heating boiler.



This blog site compares the financial and ecological effect of biomass fuel and gas. The devices expense of biomass central heating boiler is higher than that of gas central heating boiler. Thinking about the high cost of gas, the yearly operating expense (consisting of the cost of fuel, electrical energy, labors as well as maintenance) of natural gas is greater than biomass central heating boiler.



When using biomass fuels, it needs to be equipped with dirt collection agency, sulfur as well as nitrate eliminating tool to make certain the toxin exhaust satisfy the standard. When it comes to natural gas boiler, it takes on low-nitrogen combustion modern technology or denitrification gadget to guarantee the NOx exhaust fulfill the standard.



Evaluation of biomass energy

Biomass power is solar power transferred in biomass materials in the form of chemical power. It comes from the photosynthesis of environment-friendly plants. It has the form of strong, liquid and also gas. Biomass power is called a renewable energy.



According to the various sources, the biomass fuels can be classified right into 6 kinds: crop straw, forestry waste, animal dung, marine plants, energy plants, life garbage.



Biomass power has the adhering to benefits

Affordable, large distribution, big volume, renewability, storable, easy to use.



Biomass energy also has some drawbacks:

Low power thickness, not appropriate for long-distance transport. To guarantee the biomass fuel supply, it requires huge space for storage, which brings management problem.

Crop straw has wide distribution, but it is influenced by areas, seasons, weathers as well as other elements. The supply is not secure. Besides, the calorific worth varies a lot. Some are not suitable for boilers.

Different kinds of biomass fuels have various combustion effects, which may create slagging and also leaves too much ash. The alkaline content in the ash will certainly prevent the continual work of biomass central heating boiler and trigger rust.

Biomass gas are simple to obtain damp. The moisture material have great result on the burning temperature. Over-high moisture material will make the biomass gas not able to burn.

By calculation, the annual running price of biomass boiler is ￥ 2,957,400.



Gas central heating boiler.

Yearly gas expense.

As an example.

The warm effectiveness of biomass central heating boiler is 90%.


The calorific worth of natural gas is 35.58 MJ/kg.

The rate of gas is ￥ 3.1/ m3.

A gas central heating boiler can eat 315m3 natural gas every hr.

A gas boiler operates 10 hrs everyday, 300 days every year.

By computation, the annual fuel price is ￥ 2,929,500.



Yearly electrical charge.

The power of the heater is 7.5 kw.

The power of water pump as well as various other power use devices is 7kw.

So the total electrical power of the biomass central heating boiler is 14.5 kw.

The electrical energy cost is ￥ 1.0/ kwh.

The working time is 10 hours each day, 300 days yearly.

So the yearly power cost is ￥ 43500.



Yearly labor cost.

The work has 2 shifts a day.

As the gas central heating boiler has greater automation, and the operation is straightforward, it calls for only 1 fireman.

The income is ￥ 3000 monthly, so the yearly labor cost is ￥ 72000.



Yearly maintenance expense.

The maintenance job of a gas central heating boiler is not much, the cost is low.

Suppose the upkeep expense is 1% of the devices expense, then it is ￥ 2100 each year.

By estimation, the annual running cost of a biomass boiler is ￥ 3,047,100.



Conclusion.

In regards to the annual running expense, as natural gas boiler has greater automation level, calls for much less power intake tool, as well as much less upkeep, the electric charge, labor price as well as upkeep cost is lower than that of biomass central heating boiler. But taking into consideration the high price of natural gas, the complete operation cost of gas central heating boiler is higher than that of biomass boiler.



Environmental result.

Biomass gas.

Researchers gauged the emission of smoke, SO2 and NOx in 2 biomass central heating boiler.



These 2 central heating boilers has similar dissipation ability. pellet making machine for animal feed of them are not equipped with sulfur and nitrate eliminating device. But the very first one is outfitted with a bag-type dust enthusiast, as well as the second one is geared up with a film-type dirt collection agency.



The boiler geared up with film-type dirt enthusiast can lower the ash discharge effectively. In terms of SO2 exhaust, the wood pellets can fulfill the stipulated standard also without sulfur getting rid of tool. When it comes to NOx exhaust, the wood pellets can fulfill the requirement in boilers outfitted with film-type dust enthusiast.



Gas.

Gas is an excellent quality and tidy gas fuel. The fostering of gas in the central heating boiler can reduce the air pollution incredibly. The ash, sulfur and nitrogen material in the natural gas is low. The smoke of gas has little SOx, which a satisfy stated criterion. But the NOx discharge is still an issue. Looked into found the NOx exhaust of natural gas boiler is 125mg/m3, and also 25% of them is greater than 150mg/m3.



Conclusion.

According to the evaluation over, the sort of biomass gas has fantastic influence on the pollutant discharge. Timber pellets has much less SO2 discharge than straw pellets. The biomass central heating boiler with film-type dust enthusiast has far better ash removing result than bag-type dirt collector.



The NOx exhaust is beyond criterion in biomass central heating boilers without sulfur or nitrate removing tool, whatever timber pellets or straw pellets. Therefore, it is advise to gear up reliable dust collection agency, and sulfur and also nitrate eliminating device.



Gas has advantages in reducing smoke and also SO2 emission. Yet with the boosting emission requirement, even more natural gas central heating boilers will certainly adopt low-nitrogen combustion innovation and nitrate removing device.



The particular advantages of gas and also biomass gas.

The rate of biomass boiler is more than gas. Their operating expense is similar considering the rise of gas cost. Besides, the natural gas central heating boiler is less complicated to regulate, and also it doesn't take much floor room or fuel storage room.



The rate of natural gas is under federal government control, so it won't vary dramatically. The natural gas supply can be assured when the gas central heating boiler remains in usage. Biomass pellets supply is restricted by periods. The price and also supply is unsteady, which usually uses up huge storage facility room.



In regards to environmental protection, biomass central heating boilers have to be geared up with dirt collector, sulfur and nitrate removing gadget to ensure the smoke, SO2 as well as NOx emission satisfy the standard. But gas central heating boilers does not need dust collector or desulfurizer, yet it need to embrace low-nitrogen combustion technology or nitrate getting rid of tool to cut the NOx emission. Besides, the natural gas boiler doesn't require dust cleaning procedure.



On the other side, biomass fuel is eco-friendly. It is solar energy deposited in plants by photosynthesis. As data show, the biomass power created by photosynthesis is 173 billion bunch, but only 3% of them are made use of. Besides, biomass power is carbon neutral, which implies the CO2 consumption in its development equals the exhaust in biomass gas burning.



Fluidized-bed combustion is an innovation based upon gas-solid fluidized state. It has good versatility to biomass gas, the toxin gas discharge is low. By including desulfurizer to the fluidized bed, it can remove the sulfur directly, and also minimize the SO2 web content in the smoke dramatically.



Nowadays, the fluidized bed can be used for the burning of various sort of gas, suitable for the co-firing of biomass and also coals. The type of gas and their percentage is adjustable, so you can choose them according the price to lower your expense.



The high rate of natural gas is a problem. And the price difference in between summertime and wintertime is buckling down. Biomass is a superb substitute for traditional gas. To meet the ecological demand and accomplish greater cost-effective advantages, it is essential to enhance the application modern technology of biomass gas, and raise the percentage of biomass in power mix.
