Dear sir, Why APH tubes are choke and what are the causes of it's choking and what happens if we bypass the APH does it effects the fluidization of boiler?
R/sir aap ne bola ki Aph mein flue gas ka temperature 20 degree Celsius rise bola and economizer mein 16 degree Celsius rise bola hai = 1% efficiency rise why
If water having already some enthalpy then it takes small amount of heat to convert into steam, so all parameters kept in mind after Calculation we found if 6°C temperature of water increase in economiser it can increase boiler efficiency upto 1%.
APH outlet temperature may reduce due to cold and hot air mix-up, FD Air flow reduce because some amount of FD air is ingress inside aph tube, ID load increased etc.
Corten Steel.....cor= coerrosion registance and Ten= Tensile Strength because due to due point chance of corrosion and due to temp different between hot end and cold end there is chance of a little bite breaking line in cold end
Dear APH inlet me hi 300 degree rehta hai or agar APH outlet 300 degree Milne Laga ishka MATLAB APH me PA or SA air in Kiya wo kuch heat gain nahi Kiya ..jiske Karan jitna inlet me tha utna hi outlet me flue gas ka temp mil gya ...so use APH is useless and if APH outlet temp goes above 165 degree mean it create problems in ESP AND ITS DUCT which is not designed for it and APH FIRE MAY ALSO HAPPEN and sulphur and other gas may change its property may create problem
Yaar 20 degree pr 1% sabhi boilers and tri sector APH le liye bhi same hai kya?? aur kya per 20 degree flue gas temperature increase hone pr efficienecy bhi utna hi decrease bhi hota hai kya??
In our plant this type of APH available, we know flue gas having abrasive particles so it's tends to erode if outside on inside type use, if one layer is deposited over the tube then it works as insulator so less heat transfer.
@@PowerPlantDiscussion Is that a design necessity, because APH uses the air system in the tube and flue gas in the shell. and we now have frequent leakage of APH pipes, with exhaust gas temperature of 120 C. Is there really a material difference from the pipe, such as the economiser of water in the pipe and exhaust air outside the pipe
In my plant both type of APH used, APH used in CFBC Boiler air flow inside tube and flue gas over tubes but Incase of AFBC boiler- APH air flow over tubes and flue gas inside the tube. Currently m working with both types of APH used according to flue gas path.
CBD line me pressure drum pressure k equal rhta hoga, and CBD tank m pressure Kam ho jata h volume badhne k vajah se tank Ka safety 7kg/cm2 pr set rhta h. Iska value change hota h according to capacity of plant.

Sir hm aph m tubes k inside m air de aur tubes k outside m flue gases de to kya fark pdeaga boiler operation m
Koi fark ni padega, mere plant m aisa hi h flue gas outside tube and inside air, CFBC cold cyclone boiler detail

Daily one topic ka video daliye sir
Dear, Due to lack of time I can't upload daily video because m also working in power plant. For completing one video it's taking lots of time.

Dear sir,
Why APH tubes are choke and what are the causes of it's choking and what happens if we bypass the APH does it effects the fluidization of boiler?
We will discuss n seperate video very soon.

Dear Sir please tell me the temperature Of flue gasses above the 140 Centrigate
Due to acid due point (ADT), very soon I'll upload video on this topic.
Sir,If aph tubes have leaks ,then what are the first indications in dcs.please reply.
APH outlet temperature may reduce due to cold and hot air mix-up, FD Air flow reduce because some amount of FD air is ingress inside aph tube, ID load increased etc.
Thank you sir.
Chandan Sir please FD fan ke sath me Scape install kar rhe hai aaj kal uska bhi ak knowledgeable vedio banaye please

Sir ,AFBC 50TPH boiler superheater में कितने drain लगे होते हैं?
Please count dear it's depends on design
At cold end which types of tubes used in aph?
Steel
Corten Steel.....cor= coerrosion registance and Ten= Tensile Strength because due to due point chance of corrosion and due to temp different between hot end and cold end there is chance of a little bite breaking line in cold end
Small ammount moisture is also removed from fuel through hot air (APH) Thus help improve combution efficiency....
Nice

Good morning sir
Sir i have seen aph in which water use in tubes can you tell me about this why there is not using a flue gas they used a water?
Dear Air preheater as name implies here we have to heat the air by using watse flue gas. Water in coil is present in economiser.
@@PowerPlantDiscussion but sir there is also Air pre heater i have erection in which water is present
Dear sir,
Agr hum APH ka heating surface area badha kar.. APH outlet tempr 300 kar skte haii...to combustion process me kya effect hoga??
Sulfur start melting above their due point Temperature
Dear APH inlet me hi 300 degree rehta hai or agar APH outlet 300 degree Milne Laga ishka MATLAB APH me PA or SA air in Kiya wo kuch heat gain nahi Kiya ..jiske Karan jitna inlet me tha utna hi outlet me flue gas ka temp mil gya ...so use APH is useless and if APH outlet temp goes above 165 degree mean it create problems in ESP AND ITS DUCT which is not designed for it and APH FIRE MAY ALSO HAPPEN and sulphur and other gas may change its property may create problem

Yaar 20 degree pr 1% sabhi boilers and tri sector APH le liye bhi same hai kya??

Surface area change ho jaaega or uske karan jitna gain ho a hai utna nahi hoga ...
Sir
Hum fan chalane k pahle APH ko kyu chalate hai?
Fan k bad kyu nahi chala sakte hai?
How we know 20c , it's assume or I don't have understand
After implementation on different boiler found this parameter approx same
👏👏👌🙏
Thanks a lot ♥️
Why do we start air preheater before starting id fan??
FGD ka ek vdo banaiye!!
Bt in actual air flow inside tha tubes and flue gass travales out side the tubes..bt why books shows opposite..
