Description
본 발명은 LNG를 연료로 사용하는 산업용 보일러에 있어서, 연비조절 방법과 연속급수 방법을 개선하여 신속한 연비조절을 통해 연소효율을 형상시키고 자동입력 급수 인버터로 급수방법을 개선하여 운용관리 비용이 저렴하게 되는 보일러를 얻고자 한 것이다.The present invention in the industrial boiler using LNG as a fuel, by improving the fuel efficiency control method and continuous water supply method to shape the combustion efficiency through rapid fuel economy control and improve the water supply method with automatic input water supply inverter to lower the operation management cost I wanted to get a boiler.
모든 산업용 보일러는 버너의 연비 조절을 위해 시운전시 각 부하별로 공연비를 조정하여 에너지 관리공단에서 요구하는 수치에 맞추어 셋팅하고 검사를 받고 있으나 보일러의 가동조건이 항시 동일할 수는 없어 버너의 공연비는 달라지게 되며 그로인해 버너의 연소효율이 변하게 되는 것을 알 수가 있고 심하면 가스 및 공기 라인이 막혀서 짧은 시간내에 보일러 내에 그으름이 발생하게 되고 All industrial boilers are set and inspected according to the values required by the Energy Management Corporation during commissioning to adjust the fuel efficiency of the burner. However, the operating conditions of the boiler are not always the same, so the burner's air-fuel ratio is different. It can be seen that the burner's combustion efficiency changes, and if it is severe, gas and air lines can be blocked and soot will be generated in the boiler within a short time.
그으름이 발생함으로 인해서 보일러 가동을 할 수 없을 정도로 연소효율이 저하될 위험성을 가지고 가동되는 것이 현재 실정이며As a result of the soot, it is currently operating with the risk of lowering the combustion efficiency such that the boiler cannot be operated.
또, 양호한 스팀건도를 유지하기 위해 자동급수제어 방법이 공지되어 있다.In addition, automatic water supply control methods are known to maintain good steam dryness.
그러나 스팀건도를 유지하기 위해 개발된 자동급수방법은 일정수위를 벗어나면 인버터가 고정된 값으로만 작동함으로 보일러 압력을 처음과 다르게 상승시켜서 가동할 때 정밀함이 떨어져 적응이 원활하지 못한 불편이 있었다.However, the automatic water supply method developed to maintain the steam dryness, the inverter operates only at a fixed value when the water level is out of a certain level, so the boiler pressure is increased differently from the beginning, so it is inconvenient to adjust precisely when operating.
본 발명은 보일러 가동 환경에 신속히 대응하는 연비조절 수단과 급수방법을 개발하여 효율이 높고 시스템 유지관리과 비용이 저렴한 LNG를 사용하는 산업용 보일러를 얻고자함에 있다.The present invention seeks to obtain an industrial boiler using LNG that has high efficiency, high system maintenance and low cost by developing fuel efficiency control means and water supply method corresponding to a boiler operating environment quickly.
본 발명은 상기와 같은 종래의 제문제점을 해결하기 위해 개발된 것으로 배기가스 배기부에 산소센서를 장치하여 배기부의 산소량을 실시간으로 분석하고 그 정보를 마이콤에 입력하여 현단계의 연소에 필요한 급기량을 적절하게 산출하여 공급함으로써 최적의 연비를 유지할 수 있고, 또 버너 부하율과 수조내의 압력과 수조내의 온도를 실시간으로 감지하여 그 정보를 메모리를 통해 마이콤에 입력하여 급수인버터 값을 산출하고 이에 따라 연속급수가 이루어지게 함으로써 보일러 가동의 환경 변화에 신속하게 대응하는 자동급수가 이루어져 고효율 저비용의 보일러를 얻는 것이다.The present invention was developed to solve the above-mentioned problems in the prior art by installing an oxygen sensor in the exhaust gas exhaust portion in real time to analyze the oxygen amount of the exhaust portion and input the information to the microcomputer to supply the air supply required for the current stage of combustion The optimum fuel economy can be maintained by properly calculating and supplying the fuel consumption, and the burner load rate, the pressure in the tank and the temperature in the tank are sensed in real time, and the information is input to the microcomputer through the memory to calculate the water supply inverter value. By supplying water, automatic water supply is made to quickly respond to environmental changes in boiler operation, thereby obtaining a high efficiency and low cost boiler.
이와 같이 된 본 발명은 보일러 사용으로 드럼내의 급수량이 변화하면 수위감지 전극봉이 해당 수위를 감지하여 메모리에 신호를 입력하고 동시에 수조의 내부 압력을 감지하는 관체압력센서가 현재의 수조내부 압력을 감지하여 메모리에 신호를 입력하며 또 현재의 수조 내부 온도를 감지하여 메모리에 신호를 입력하고 버너부하율을 실시간으로 감지한 종합정보가 각자의 메모리에 입력되고 마이콤에 입력되어 메모리와 연산이 되므로 보일러가 작동 환경에 맞는 현재의 급수 인버터 값을 계산하여 출력하므로 전극봉 수위마다 입력값을 조정할 필요 없이 자동적으로 압력변화에 대응하는 연속급수가 달성되고 배기가스 배출부에 산소센서가 장치되어 실시간으로 배출되는 산소량이 감지되어 마이콤에 입력되고 현재 상황에 맞는 급기량이 산출되어 송풍기 인버터값을 계산출력하므로 풍속, 풍량, 풍압이 감안된 값으로 자동조절되어 설정된 연소효율에 맞는 급기량을 공급하게 된다.In the present invention as described above, when the water supply in the drum changes due to the use of a boiler, the water level sensing electrode detects the corresponding water level, inputs a signal into the memory, and simultaneously detects the internal pressure of the water tank by a pipe pressure sensor that senses the internal pressure of the water tank. Inputs a signal into the memory and senses the current temperature inside the tank, inputs a signal into the memory, and burns the burner load rate in real time. It calculates and outputs the current feedwater inverter value according to the level, so that continuous water supply corresponding to the pressure change is achieved automatically without the need to adjust the input value for each electrode level, and the oxygen sensor is installed in the exhaust gas outlet to detect the amount of oxygen discharged in real time. Is inputted to the microcomputer and the air supply for the current situation is calculated. Blower so calculated output value of the inverter is automatically adjusted to a given wind speed, air volume, wind pressure value is supplied to a feeding amount for the predetermined combustion efficiency.
따라서 최적의 연소효율을 발휘하게 되어 안정적인 가동을 할 수 있게 되며 급기량과 급수량의 공급은 마이콤 시스템에 의하여 유지 관리되므로 현황 파악이 용이하게 되고 유지관리 비용도 저렴하게 되는 이점을 얻는 것이다.Therefore, the optimum combustion efficiency can be achieved and stable operation can be achieved. The supply of air supply and water supply can be maintained by the microcomputer system, so that it is easy to grasp the current status and the maintenance cost is low.
