| Cleansing The Mind A master, a guru taught his disciple all that he knew. Having taught all the scriptures, he told the disciple that for the final teaching he will have to go to a near by ashram. The disciple was told that there in the ashram, the other guru shall impart final teaching. The disciple was wondering why his guru would send him to another guru even though his guru was much more knowledgeable than the other guru who was expected to give him the final teaching. |
|
Though in a dilemma, the disciple decided to obey his guru and went to the nearby ashram to meet the other guru. To his surprise, he found that the other guru had stopped teaching. He was engrossed in serving food to his disciples with love, cleaning up the leftovers, washing the dishes etc. The disciple saw this and learnt what it meant to serve out of love. Later he noticed something profound. The guru himself washed the dishes and kept them in order before going to sleep. Next morning, the disciple again observed that the other guru took out the dishes, washed them again and started cooking. The disciple wondered as to why the other guru washed the dishes all over again in the morning while they were already been washed thoroughly earlier in the night and all the dishes were not dusty either. The disciple observed all such details and came back to narrate to his earlier guru. He said, I cannot understand the strange fact of why the other guru in the ashram wash the already cleaned vessels again in the morning. What is the necessity of doing this? The earlier guru replied, ‘Yes, this is the understanding that I wanted you to observe and get it completely.’ We clean our mind regularly, but our mind starts collecting dust along the way in the form of a clutter, foggy and unclear understanding. So long as the mind gathers dust, it has to be cleaned. It is a constant process. |

Question: What are the advantages of using Active Harmonic Filter (AHF)?
Answer: Following are the advantages: - Harmonic distortion is reduced. As current distortion results in voltage distortion the voltage distortion is also improved.
- Effective power factor is improved. AHF can maintain the power factor at set value irrespective of the changes in the load power factor.
- Harmful effects such as more losses, more heating, degradation is reduced in case of motors, generators, PF capacitors, cables, fuses, transformers etc.
- Transmission and distribution losses in plant are reduced.
- Malfunction of components / equipment such as static relays, thermocouple -temperature indicators, PLC, telephone system, digital indicators and so on is eliminated.
- The industrial plant will comply with Harmonic Standard such as IEEE 519:2014 standard if the harmonics are filtered to remain within limits.
- Apart from harmonic filtering, AHF can also perform reactive power compensation and load balancing which helps to utilize the installed transformer capacity to the fullest.
- Can adapt to the changes in harmonic spectrum of load.
- Performs effectively irrespective of supply frequency variation.
- No possibility of resonance.
- Responsive only to the non-linear load it is supposed to take care of.
- Overall efficiency and reliability of the plant is improved.
- Harmonic filtering results in energy-saving up to 3% to 5%. The monitory saving can be because of the two things mentioned above. However, mitigation of harmonics results in prevention of plant failures, retardation of component degradation etc. This avoids huge losses in plant which is much more substantial than payback due to energy saving.
Harmonics are harmful to the plant as a disease to human body. Hence one should keep them under control. Amtech can help you if you are facing any harmonic related issue. We have range of products to address the power quality issue.

APPLICATION CASE STUDY - Energy saving in Furnace Blower |
|
Problem: Difficulty in maintaining adequate furnace temperature and quality of material due to uncontrolled fire contents like coal powder, oil and gas. |
|
|
All forced hot air furnaces are equipped with a furnace blower that works to circulate throughout the house. A home heater or furnace, that uses forced hot air consists of burner, plenum & furnace blower. In the typical forced hot air system, burner is fired by oil, natural gas, or coal powder. Air that is heated by burner is gathered in the plenum. The hot air is then forced, or blown from the plenum throughout the house by the furnace blower. |
|
There are three different zones in furnace like socking, heating and preheating with each zone having different temperature range like socking temperature from 900...1250 °C, heating temperature from 750...900 °C and preheating temperature from 600...750 °C. The furnace blower is feeding material in socking zone and metal row material enters into preheating zone. |
|
Limitation of previous system: - Uncontrolled furnace temperature due to fix blower speed.
- Quality of material not up to the mark.
- Reduction in weight of final product material.
Challenges: - Loss of the costly material like gas, oil and coal powder as the fuel content is uncontrolled due to fix motor speed.
- High starting current kick.
- Cooling down of excessive surrounding plant temperature.
Solutions: - Provided Axpert-Engineered System with VFD.
- Saving of gas, oil & coal powder due to automatic speed control of blower by sensing carbon content form pre-heater zone by fuel content analyzer & VFD.
- Very smooth operation due to VFD.
- Surrounding plant temperature reduced due to controlled furnace temperature.
Benefits: - Power saving of the order of 25% & fuel saving of the order of 10% through automatic speed control.
- Improved quality of final product material and elimination of material weight loss problem.
- Accurate control of furnace temperature.
- Reduced mechanical wear & tear.
- No starting current kick due to smooth starting of the motor with VFD.
