ANALYSIS OF ENERGY-SAVING CAUSED BY USING BIOMASS FUEL IN COAL-FIRED BOILERS
EVALUATION OF ENERGY-SAVING BROUGHT ON BY USING BIOMASS FUEL IN COAL-FIRED BOILERS

ANALYSIS AND ALSO BURNING ATTRIBUTES OF BIOMASS FUELS

The supposed biomass fuel is a fuel that includes organic products such as plant materials and also animal waste, as well as is the new name for the earliest fuel. Usually speaking, we claim that the chaff, timber cutting, stem-shaped plants, peanut shells, bark, sawdust, etc, are the fuels commonly made use of in the agricultural society in the past.

As the sector creates slowly, it is abandoned, but now it is located that these fuels are generated. The pollution is far less than the primary fuel of contemporary sector - coal. So in the past few years there have been numerous central heating boilers devoted to biomass fuels, and also numerous coal-fired central heating boilers have actually been exchanged biomass fuels, however few examples of fuels can be totally made use of.

https://bestiya.net/ and also H material of biomass fuel are high, indicating that it is easy to shed and burns quickly. It can adapt to boilers with high water-cooling conditions in the heater, as well as at the same time generate even more flue gas than coal, so the heater is much better than regular coal-fired boiler. Larger.

https://pabrikpavingblock.com/how-to-make-chicken-feed/ is also as a result of the high web content of unpredictable issue as well as H, a big quantity of water vapor is generated in the fuel, a huge quantity of heat is soaked up, and also the C content is relatively tiny, so the low calorific value of the biomass fuel is reasonably low. The exact same central heating boilers, such as fuel, are biomass, which needs almost two times as much fuel as bituminous coal.

Biomass fuel growth and also burning attributes

Biomass fuels are prominent as a spin-off of agricultural and forestry items. The use of biomass fuels is a procedure that turns waste right into prize. Biomass fuels originate from a large range of resources as well as are easily offered for boilers in the agro-processing sector. China affixes great value to the growth as well as usage of bioenergy.

Biomass fuel pellet products are still rarely utilized in China. We are primarily melting directly, as well as the fuel combustion condition is not positive, and also the fuel calorific worth utilization is still extremely low.

Since biomass fuel itself is taken into consideration to be waste use, it is not taken seriously from the management of the company to the management of the federal government for its absolutely effective use.

Standing of biomass fuel used in coal-fired boilers

In the vast backwoods, the products we used to call biomass fuels were burned in the fields as well as utilized as plant foods to make white smoke all over in the field and also contaminate the environment.

When using biomass fuel, a lot of these systems of use do not use the biomass fuel, so the boiler room is typically "smoke-smoke" when burning, the fuel is piled up indiscriminately, as well as the usage of fuel calorific value is extremely low.

The residue produced during the combustion process frequently blocks the flue, causing the boiler to shed on the regular fire, causing waste, and the boiler output is commonly insufficient.

Thermal performance test of coal-fired central heating boilers utilizing biomass fuel The boiler thermal efficiency basic test is a way to measure the thermal effectiveness of the central heating boiler by means of boiler thermal back-balance.

The supposed boiler thermal counterbalance is to determine the energy loss of various components and also kinds of central heating boiler procedure, and also subtract the percentage of these energy losses to get the boiler thermal efficiency.

This method can better discover the key point of power waste in the central heating boiler operation process, and also can grasp the trick to resolve the boiler energy effectiveness problem via discovery and also analysis, so regarding suggest options according to local conditions.

5 Ideas on making use of coal-fired central heating boilers to improve central heating boiler thermal effectiveness According to the above energy loss discovery, the primary power efficiency troubles of many coal-fired boilers making use of biomass fuel are:

1. The exhaust gas temperature level is very high, typically reaching over 400 ° C, and the main biomass fuel continues to burn in the tail pipeline;

2. The warmth loss of the gas is not totally melted, and also the carbon monoxide web content of the tail flue gas is high. Because of the traveling of the fuel, the regional oxygen supply is doing not have, to ensure that the gas is not totally melted.

3. The heat loss of the strong incomplete burning is high, likewise because of the fuel flying. As well as melt, and also some do not melt totally right into the chimney.

Relative to these troubles, the following boiler reform propositions are proposed:

1. Strictly regulate the air volume and heating system adverse pressure, lower the flue gas flow speed, and minimize the fuel trembling rate.

2. Expand the heating system volume to raise the fuel quantity to make sure that the output will not be because of making use of biomass. The fuel is clearly decreased, all the heating system arches are removed, the biomass is very easy to fire up, the heating system arc is not really efficient, and also the ash deposit is little, as well as the grate height can additionally be lowered.

3. The second air is added at the exit of the heater to block a big amount of fuel from flying away. As well as increase the oxygen content in the smoke course to ensure that the combustion can proceed smoothly.


Verdict

With the broad application of biomass fuels, the re-election of coal-fired central heating boilers with biomass fuels has actually become particularly important. The automation of biomass fuels will also be formed. It is beneficial to China's present energy usage framework and also is conducive to energy saving. The standard national plan of usage.
