FUEL COMBUSTION CALCULATION BASED ON FLUE GAS ANALYSIS | CHEMICAL ENGINEERING CALCULATIONS | ORSAT
HTML-код
- Опубликовано: 13 окт 2024
- On this video, we will be solving a combustion problem based on flue gas analysis. It will help us understand further the concepts in combustion engineering. We will be taking the ORSAT analysis and other requirements by applying different chemistry and engineering concepts that we learned from previous topics.
This is a continuation of our lecture course for stoichiometry of fuel combustion under the chemical engineering calculations course. Language is in mixed English and Filipino / Tagalog.

Enginerds RUclips channel aims to provide FREE lecture videos, tutorials, solved problems and exercises, news, scientific and engineering articles and informative vlogs for engineering students. We are working hard to update our lessons from time to time. Our topics are ideal for Engineering students, STEM students and engineers who would like to have a free refresher courses. Some of the topics that we are covering in our channel are:
• Thermodynamics
• Transport processes and Momentum Transfer (heat transfer, fluid mechanics and hydraulics, diffusion, etc.)
• Separation Processes (distillation, evaporation, drying, liquid extraction, leaching, etc.) | also referred to as unit operations
• Engineering Topics (engineering economy, engineering mechanics, strength of materials, etc.)
• Engineering Mathematics (algebra, trigonometry, solid and analytic geometry, differential and integral calculus, differential equations and advanced engineering mathematics)
• Chemistry (General chemistry, organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, biochemistry, environmental chemistry)
• Physics
• Chemical engineering topics (chemical engineering principles and calculations, environmental engineering, equipment and plant design, reaction kinetics, chemical process industries, etc.)
• Career related topics (quality control, process engineering, health and safety, maintenance, etc.)
• Board exam solved problems and exercises
We also publish articles and vlogs that covers the following:
• Engineering, science and technology news
• Personality development
• Business vlogs
• Study tips and advice to students
Enginerds is working along with other channels such as (1) Chemical Engineering Philippines and (2) STEM Philippines.
We are also offering an ONLINE LEARNING PROGRAM for students who would like to enroll to our online courses. See details below:
ENGINERDS ONLINE LEARNING PROGRAM
Enginerds Online Learning Program offers an after school online learning support for High School, STEM and Engineering students in mathematics, chemistry and physics. By enrolling in one of our courses, you will be able to secure an access to all the website’s features:
• Online lecture videos
• Online quizzes
• Answer keys to online quizzes (tutorial video)
• Access to our online community
• Access to our reference materials and articles
You can start by registering for FREE and access our FREE courses:
Online Academy: school.enginer...
Our goal is to assist Filipino students who wants to become an engineer in the future. By enrolling in our program, the student can study the subjects even without having enough references on particular subjects because our courses are mostly compilation of lectures and solved problems from different textbooks and references. We wanted the students in Philippines to be able to study the subject even if they lack the necessary resources. In our website, students can collaborate with other enrolled students and discuss topics related to their enrolled subject.
Enginerds Online Learning Program is ideal for High School, STEM and Engineering students. Lessons are mostly mixed English and Filipino (Tagalog). As much as possible, we do not want language to be a barrier in learning engineering for it is a separate matter. We believe that if lessons are taught in the language that is most familiar to them, communication will be more efficient.

Is this lecture video useful to you? Please leave a comment
As an HVACR student this is very useful, it’s a shame my classmates and Professors only understand English.
Kinda confused. Bakit po C to CO2. Kung pwede naman po nakabase sa C3H8 > CO2?
Omg thank you sir. Very helpful for us.
Thank you also for watching the video. Please subscribe for more. Have a nice day
Please i want to know why H from H2 is 28 kgmole instead of 7kgmole
I mean if two hydrogen atom forms H2
A blast furnace gas analyzing 27% CO, 12% CO2, 2% H2, 5% CH4 and 54% N2 at 25degC and 98 kPa and saturated with water vapor is used as fuel in a boiler. Air is supplied 15% excess at 30degC, 762 torrs and also saturated with water. 90% of the total carbon in the fuel is converted to CO2, the rest CO. Molar ratio of H2 to CO is 1:4 in the stack gas which leaves at 200deC and 750 torrs. Calculate:
a. Orsat analysis of the stack gas
b. moles stack gas/mole fuel nakuha kuna yung letter A boss paanu yung B?
Hi, if you already got the Orsat analysis of the stack gas, then it means you already know the number of moles of the stack gas (excluding water) which is 2.11525 moles. The next step is to find the total number of moles of water in the stack gas which would include the (1) water formed from the H in the fuel minus the unburned H2 in the stack gas which you will use the molar ratio given (2) moles of water from the fuel, using Antoine's equation and (3) moles of water from air, using Antoinne's equation. You will add all these number of moles of water to the number of moles of gases in the stack gas that you got from your Orsat analysis. You should get 0.2002 moles.
Finally, you will divide the number of moles of stack gas (2.315 moles) to the number of moles of fuel gas (1.033 moles). You should get 2.2415 ratio.
Thank you boss
For the following process, draw the materials flow diagram, write the independent reactions, do the degree of freedom analysis and complete the materials and energy balances
The combustion of a gas containing 96% CH4, 1.8% CO, 2.2% N2, flowing in at 50 m3/s occurs in a continuous process. The gas and air enter at 298 K. Calculate the flame temperature when air is enriched with 30% oxygen.
I need help sir
saan galing ung basis an 100 kg moles of dry gas?
Great
Hello po! Corrupted po yata yung video? Puro green lang po ang nasa screen.
Hi. It is not corrupted, it is just an issue with the browser. This is actually an issue that content creators are facing since there are some browsers (like chrome browser) seems blocking videos that "potentially" contains copyrighted materials. We did our best to avoid this. As you can see we already removed any background music and just focused on the lectures. However, the same thing is happening in some videos.
You can however do any of these to watch the video: (1) copy the link and watch in other browsers like firefox, microsoft edge, safari, etc. or (2) Clear you chrome browser catche and cookies.
I hope this helps. Thank you for your support.
