The following specification particularly describes the invention :

Background of the invention
This invention is related to an improved 'Burner Management which is automated for Yarn Heat Setting which is a crucial stage in the textile industry for straightening of the yarn. The system is a big leap forward towards the efficient, safe, easy to use and cheap yarn heat setting system. The invention not only addresses the above issue but is also a futuristic one. It strives to eradicate the need for costly and fast exhausting sources like LPG and fuel used for electricity production. This invention in many times more safer and better equipped to resolve the intricacies and issues that arise during the yarn heating process.
For generating the electric power, thermal power plants using fossil fuels, such as coal and petroleum products, in liquid or gaseous form are in use. Fossil fuels are available in limited quantity which may get exhausted in near future. Further all these plants are releasing pollutants in the atmosphere and causing big environment problems. Some small size thermal power plants work on agricultural waste such as wood, bagasse and the like as a fuel, which also create environmental problems. All the thermal power plants release huge quantities of carbon dioxide which further speeds up the ozone layer depletion, green house effect and global warming.
Even the other types of the plants that for generating electricity like hydel power plants need big dams across rivers. These dams cause displacement of human beings, animals, and plants and in turn disturb the ecological balance of the vicinity. They even involve huge costs of construction.

There are even more drastic issues with other sources of electricity production like nuclear power plants etc. And this is not enough as we continuously face the killer pollution with all of these resources.
Now is the time for eco friendly and safely disposed source of energy and the proposed invention is the step forward towards their wide usage in the future to have a clean, healthy and safe future.
Prior Art
The yarn heat setting process requires heating of the yarn. For the same, the systems presently in existence offer significantly inefficient and unsafe means of doing the same. The fuel sources presently used include LPG and electricity. Moreover, as there is no automation offered so far, the existing systems has many drawbacks which may lead to fatal accidents.
Disadvantages of present systems
There are numerous disadvantages of the present system. One of the major disadvantages of using LPG is manual firing of burners with all possibilities of backfire, which is very dangerous for people working around. Human loss due to this is definitely intolerable and by every means drastic. LPG cylinders are kept in hot water to ensure full utilization, which is fraught with possibility of cylinder bursting. This again can have similar consequences as in the above case. Availability, transportation and storage of LPG are big issues. Though not as brutal an issue as the above ones but is certainly a significant issue when the

cost effectiveness is an issue. Why go for costly and thereby less efficient solutions when easier and more efficient non-conventional source of energy is easily available. This issue translates to common man spending more and more on one of his three basic necessities.
There is every possibility of short circuits incase of immersed electric coil set-ups. This might again lead to human loss in extreme cases. Sudden power cuts or non-availability of LPG in mid of process leads to damage of entire loaded batch resulting in huge financial loss. Auto temperature controls not available which always is a big threat for maintaining the quality of yarn. These above mentioned issues lead to propose a system that is safe and efficient.
Detailed description of The Invention
The automated burner management system comprises of burner, non-IBR-boiler, steam storage and moisture removal section, vacuum chamber, two set point pressure switch, sequence controller, water level controller, gas leakage detector and flame monitoring device.
The automatic burner management system uses the natural gas as its primary resource. The natural gas from the gas source is used to operate the burner. Initially the pilot fire is started and after it stabilizes the solenoid valve opens up for the passage of the natural gas. The burner then heats the non-IBR boiler, which contains water maintained up to a particular level. The steam produced thereafter then proceeds to the steam storage and moisture removal section where this steam is stored and moisture is removed from it. The steam then moves to vacuum chamber for processing the yarn (i.e. heating the yarn).

The steam producing vessel is fitted with two set point pressure switch. Once the maximum pressure is attained a signal is transmitted to sequence controller and it will in turn off the solenoid valve. The advantage of this system is that it avoids bursting of pressure vessel due to over pressurizing. It also reduces gas wastage thereby increasing the efficiency of the system. If now the pressure lowers the burner restarts automatically. If the water level goes below the minimum required level the burner is shut off automatically. In case of Gas Leakage the Gas Leakage Detector gets activated and shuts off the solenoid valve avoiding the chances of fire. After the pilot flame gets stabilized the main solenoid valve opens up. If the main flame doesn't start or if after establishing it goes off again, the Flame monitoring device senses the same and sends necessary signals to the sequence controller for closing the solenoid valve.
Initially the gas leakage check is done (manually with the soap solution). Then main solenoid valve is opened. Then the burner start button on the panel is pressed to control the system automatically. First the solenoid valve is opened and gas starts flowing. Based on required time setting in the sequence controller the pilot igniter creates spark putting the pilot flame "ON". If the pilot flame doesn't get ignited the flame monitoring device sends signal to the sequence controller to shut off the solenoid valve. The above mentioned steps are repeated till the pilot flame is ON. The steps are repeated and if the problem persists then restart button on the panel can be used to restart the system.
The proposed burner management system explained above obviates all the drawbacks of the existing systems and proves to be superior due to the many advantages.
5

1. It is safe and convenient system which initially starts just by pressing the start button ON to control the entire process automatically.
2. It is very easy, convenient and efficient to use.
3. Possibility of mishap is reduced to zero. This eradicates the unbearable loss of the human resource which itself is extremely important.
4. Continuous availability of Natural Gas eliminates the possible production loss as well as raw material loss caused due to erratic power supply or LPG unavailability.
5. This system offers substantial cost effective solution because Natural Gas is cheaper than both commercial LPG and electricity by 60% and 70% respectively. This leads to availability of product to the end consumers at cheaper rates and they do not have to necessarily pay for the inefficiency of the manufacturer.
