Benefits of technology

[0028]In the system and method for diagnosing and controlling an incineration facility and solid fuel boiler and managing the life cycle of a facility through a heat exchange and a design program and an operation mode analysis of an operator according to the resent invention, the data of one minute long are stored in the heat balance, the design program, the MMI which is an incineration facility control program, and the chimney automatic measurement system (TMS: Telemetering system), and based on the above data, the process design performance suggested when designing the initial incineration system and the actual operation value are compared and analyzed in real time, and via the real time diagnosis and analysis on the operation type of the operator, the combustion efficiency, for example, an operation group for each individual is evaluated, so an efficient operation and management of the incineration facility are available, thus enhancing energy power generation efficiency.
[0029]In addition, various analyses may be available in such a way that there are various search functions for certain items (an operation date, incineration facility outlet temperature, an exhaust gas amount, a steam generation amount, a combustion air amount, a waste agitating speed, etc.), and when the operator designates a predetermined rage, the designated range is analyzed, and any relationship with other search items can be reviewed, so the efficiency operation and management of the incineration facility are possible, thus enhancing energy power generation efficiency.
[0030]In particular, the present invention may be constituted into a system which can be installed on site, so the good combustion condition (3T) can be efficiently maintained in the combustion chamber in such a way to use the secondary amount of combustion air and automatic flow rate adjusting device which are appropriate to the combustion of various wastes.
[0031]In addition, it is possible to increase waste heat recovery energy in such a way to analyze and support in real time the operation values by the operators, and the PLM system may be used by applying the electronic tag (NFC) and a wireless communication technology, whereby it is possible to enhance the residual value of the facility.
[0032]In addition, technology power (professionalism) can be doubled in such a way to use a system wherein an operator's self-learning and remote diagnosis are available by enforcing an educational function with respect to a professional technology, for example, an incineration design program and an operation manual.
[0033]The additionally accumulated operation data can be analyzed in real time and can be feedback to a designing, construction and operation, so they can be used as a design factor. The present invention which can be developed in the form of a web may allow a 1:1 consultation between the operator on site and the related expert, and a continuous management is available.

Problems solved by technology

The technology on a design, construction, operation and diagnosis of the environment basic facility remains currently at a basic level, and an energy recovery ratio is very low, and a facility management is not efficiently carried out.
Actually, there in general are conflicts (a criteria lack in accurate operation data analysis) between an ordering company and an installation company since a diagnosis evaluation and verification are not properly carried out on the above design factors after an incineration facility is installed.
To this end, such a system may not operate normally under conditions where heating values and composition of wastes change in various forms.
For this reason, the automatic operation systems installed in Korea are not operating normally.
For the sake of destruction or inhibition of an incomplete combustion product which generates in the course of combustions of incineration materials, a mixture with air with the aid of strong turbulence may be necessary at over a predetermined temperature; but in case where the amount of air decreases, the flow speed at an end of a secondary combustion air nozzle may become slow, so the destruction of the incomplete combustion product may weak in the incineration facility.
Meanwhile, since a detailed combustion situation in the actual incineration facility is very nonuniform and measurement is almost impossible, a total operation control system is necessary, which is able to manage or recognize the whole combustion situations using a heat balance program and the measurement value of the temperature in the incineration chamber (an outlet temperature of an incineration facility, an upper side temperature in a drying zone, and an upper side temperature in a post-combustion zone) and an oxygen concentration and a combustion gas amount at a rear end of the boiler.
The combustion phenomenon which occurs in the combustion chamber of the incineration facility is very complicated, and the temperatures and the generation amount of the combustion gas components and the non-combusted components contained therein are different.
The amount of data (big data) is very huge, so it is actually impossible to analyze the data in real time.
More specifically, a simple search function with respect to the operation adjusting value generating when the operator operates and the output value with respect to a result of the operation is available, but the completely automatic operation is actually impossible with respect to the incineration facility thanks to the characteristics wherein the operation conditions change from time to time due to the composition of various wastes.
Therefore, the automatic operation system (Auto Combustion System) which has been conventionally installed, does not remain efficiently operated due to the above problems, whereupon the above automatic operation system is almost useless.
In a part of the incineration facility, an actual situation is like that a systematic management is not being carried out, for example, the data stored in the MMI are lost.
To this end, error, missing, etc. are frequently taking place when inputting again into a PC, etc., so there may be a limit to using it as objective and universal data.
The incineration facility is an expensive plant facility and a facility which has 20˜40 years of plant life cycle management from the initial design to the destruction through operations.
In the real situation, the operator may be any inhibiting factor in terms of an efficient operation of the facility since a design concept on an incineration facility is ambiguous, and professional knowledge lacks, and any chance to take a professional education is losing due to shifts.
