What is the purpose of flue gas analysis?

What is the purpose of flue gas analysis?

A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion. Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter.

What is flue gas analysis?

Flue gas analysis will give you an indication of whether or not you are achieving maximum possible carbon combustion in your fuel. You can also analyse your flue gas in order to determine environmental impact and whether you are maintaining compliance with local emissions regulations.

Is flue gas dangerous?

Caring for Your Chimneys & Flues When gas and oil burned for heat, the dangerous fumes produced range from soot (particulate matter), to nitrogen dioxide (also toxic), to acidic water vapors formed when moisture condenses. None of these pollutants should be allowed to leak from the chimney into your living space.

Is a higher heat of combustion better?

Heats of combustion are used as a basis for comparing the heating value of fuels, since the fuel that produces the greater amount of heat for a given cost is the more economic. Heats of combustion are also used in comparing the stabilities of chemical compounds.

How do you find the specific heat of a flue gas?

Calculation method of aC is given by the following equation:(16) a C = a m a cp where, acp can be defined as the specific heat ratio of CO2 to CO2. So, acp equals to 1. am can be indicated as the mass ratio of CO2 to flue gas for n = 1.(17)

How do you find the specific heat of superheated steam?

From the energy in the superheat shown, the specific heat capacity can be determined by dividing this value by the temperature difference between saturation temperature (100 °C) and the superheated steam temperature (400 °C):

What is the maximum temperature of steam?

375 degree celcius

What is the specific heat of steam?

The specific heat of steam is 2.010 kJ⋅°C-1kg-1 .

At what temperature is steam superheated?

100 °C

What are the advantages of superheated steam?

• Steam can be superheated without applying high pressure.
• Compared to heated air, superheated steam has a high thermal capacity per unit volume, offering extremely high thermal conductivity.
• Compared to hot air, superheated steam has much more powerful drying capability as it is vapor with high thermal conductivity.

What is the benefit of using superheated steam?

Advantages of using superheated steam to drive turbines: It is advantageous to both supply and discharge the steam while in the superheated state because condensate will not be generated inside steam-driven equipment during normal operation, minimizing the risk of damage from erosion or carbonic acid corrosion.

What is meant by quality of steam?

What is Steam Quality? Steam quality is the proportion of saturated steam (vapor) in a saturated condensate (liquid)/ steam (vapor) mixture. A steam quality of 0 indicates 100 % liquid, (condensate) while a steam quality of 100 indicates 100 % steam.

How many types of steam are there?

three

What do you mean by dry saturated steam?

Dry saturated steam: Saturated (dry) steam results when water is heated to the boiling point (sensible heating) and then vaporized with additional heat (latent heating). If this steam is then further heated above the saturation point, it becomes superheated steam (sensible heating).

What is meant by dry steam?

Dry steam is steam that is at the temperature of saturation, but does not contain water particles in suspension. It has a very high dryness fraction, with almost no moisture. Commercially, dry steam contains not more than one half of one percent moisture.

How is dryness factor calculated?

Calculating the Total Heat of Wet Steam

1. X = Dryness (% / 100)
2. νf = Specific Volume of Saturated Water.
3. νg = Specific Volume of Saturated Steam.

What are the two types of steaming?

There are also two kinds of steaming methods, which are “low pressure steaming,” or also known as “atmospheric,” and “high pressure steaming.” Low pressure steaming is a process where food could be steamed through neither an indirect nor a direct contact with the steam, while high pressure steaming is when foods are …

Which is faster steaming or boiling?

Steaming is faster than boiling. Steaming is far more energy- and time-efficient than boiling. boiling because most of you are wasting your time, waiting for a big pot of water to boil while your hungry family sits growing more famished.

Is steaming healthier than boiling?

Researchers found steaming kept the highest level of nutrients. “Boiling vegetables causes water soluble vitamins like vitamin C, B1 and folate to leach into the water,” Magee said. Steaming is a gentler way to cook because the vegetables don’t come in contact with the boiling water.”

Which is better blanching or steaming?

What’s the Difference Between Boiling and Steaming? Steam blanching, which takes a few minutes longer than your average blanching time, typically maintains more of the nutritional value than water blanching, dropping vegetables straight into boiling water, where nutrients can get extracted and lost forever..

Is it better to steam or boil frozen vegetables?

Steaming frozen veggies = bad flavor and texture. Sautee or roast instead! However, there are certain vegetables that can actually lose their flavor and nutrients from steaming. While it is still true that steaming is better than boiling, preparing vegetables with steam is still not ideal.

What are the disadvantages of steaming food?

However, the disadvantage with steaming is that it is a slow method of cooking. Steaming is often confused with Pressure cooking, which is different as pressure cooking requires the food to be immersed into the boiling water, whereas steamed recipes do not require any direct contact of the water with food.
