When it comes to gas central heating boiler, it adopts low-nitrogen combustion innovation or denitrification gadget to make certain the NOx discharge meet the standard.



Evaluation of biomass energy

Biomass energy is solar power transferred in biomass products in the form of chemical energy. It originates from the photosynthesis of eco-friendly plants. It has the form of strong, liquid and also gas. Biomass energy is known as a renewable energy.



According to the different resources, the biomass fuels can be identified into 6 kinds: crop straw, forestry waste, animal dung, aquatic plants, energy plants, life garbage.



Biomass power has the following benefits

Affordable, broad circulation, big quantity, renewability, storable, easy to use.



Biomass power likewise has some disadvantages:

Low power thickness, not ideal for long-distance transportation. To make sure the biomass gas supply, it needs big area for storage, which brings monitoring issue.

Crop straw has vast circulation, but it is affected by regions, periods, weathers and also various other elements. The supply is not secure. Besides, the calorific worth varies a whole lot. Some are not suitable for boilers.

Various kinds of biomass gas have various burning impacts, which may cause slagging and leaves too much ash. The alkaline material in the ash will certainly impede the continuous job of biomass central heating boiler and also create rust.

Biomass gas are simple to obtain damp. The dampness web content have fantastic effect on the combustion temperature. Over-high moisture content will certainly make the biomass fuel incapable to burn.

Ecological impact.

Biomass fuel.


Scientist determined the exhaust of smoke, SO2 and NOx in 2 biomass boiler.



These 2 central heating boilers has similar dissipation ability. Both of them are not furnished with sulfur and also nitrate removing device. Yet the very first one is equipped with a bag-type dust collection agency, as well as the 2nd one is furnished with a film-type dust collection agency.



The central heating boiler equipped with film-type dirt collection agency can lower the ash discharge successfully. In terms of SO2 emission, the wood pellets can meet the stipulated standard even without sulfur eliminating gadget. When it comes to NOx discharge, the wood pellets can meet the criterion in boilers equipped with film-type dirt collector.



Gas.

Natural gas is a premium quality and clean gas fuel. The adoption of natural gas in the central heating boiler can lower the air pollution incredibly. gemco pellet mill price , sulfur as well as nitrogen material in the gas is low. The smoke of gas consists of little SOx, which a satisfy stipulated standard. But the NOx discharge is still a problem. Looked into discovered the NOx discharge of gas boiler is 125mg/m3, and also 25% of them is greater than 150mg/m3.



Conclusion.

According to the analysis above, the sort of biomass fuel has great influence on the contaminant discharge. Wood pellets has less SO2 exhaust than straw pellets. The biomass boiler with film-type dust enthusiast has far better ash getting rid of result than bag-type dust collection agency.



The NOx exhaust is past criterion in biomass central heating boilers without sulfur or nitrate eliminating device, whatever timber pellets or straw pellets. For that reason, it is recommend to furnish effective dust collector, and also sulfur and nitrate eliminating tool.



Gas has advantages in cutting smoke and SO2 discharge. But with the enhancing discharge standard, even more gas boilers will adopt low-nitrogen burning technology as well as nitrate eliminating tool.



The particular advantages of gas and also biomass gas.

The cost of biomass boiler is higher than gas. Richi machinery operating cost is similar taking into consideration the rise of gas price. Besides, the gas central heating boiler is simpler to regulate, and it doesn't take much floor space or fuel storeroom.




The price of gas is under federal government control, so it will not vary greatly. The natural gas supply can be guaranteed when the gas central heating boiler remains in usage. Biomass pellets supply is restricted by seasons. The price and supply is unpredictable, which typically occupies large storage facility space.



In terms of environmental protection, biomass boilers have to be furnished with dust collection agency, sulfur and also nitrate eliminating tool to make sure the smoke, SO2 as well as NOx discharge satisfy the standard. But natural gas central heating boilers does not require dirt collection agency or desulfurizer, however it need to adopt low-nitrogen burning innovation or nitrate getting rid of device to reduce the NOx emission. Besides, the gas boiler doesn't need dust cleansing procedure.



Beyond, biomass gas is eco-friendly. It is solar energy transferred in plants by photosynthesis. As statistics show, the biomass power created by photosynthesis is 173 billion bunch, however only 3% of them are used. Besides, biomass power is carbon neutral, which means the carbon dioxide intake in its development equates to the exhaust in biomass gas burning.



Fluidized-bed burning is an innovation based upon gas-solid fluidized state. It has great flexibility to biomass gas, the toxin gas exhaust is reduced. By adding desulfurizer to the fluidized bed, it can get rid of the sulfur straight, as well as minimize the SO2 content in the smoke dramatically.



Nowadays, the fluidized bed can be used for the burning of different kinds of gas, appropriate for the co-firing of biomass as well as coals. The kind of gas as well as their percentage is adjustable, so you can select them according the cost to decrease your price.



The high cost of natural gas is an issue. And the rate difference between summer and also winter is buckling down. Biomass is an outstanding substitute for conventional gas. To satisfy the ecological requirement as well as attain greater affordable benefits, it is very important to enhance the application innovation of biomass gas, as well as increase the percentage of biomass in energy mix.
