A method for analyzing or optimizing the operation of waste incinerator systems. The content of CO2 is measured in the exhaust gas and is used to determine the ratio of biogenic carbon to fossil carbon in the incinerated waste, if necessary after resetting to the CO2 reference quantity. The variability of the CO2 reference or the ratio of biogenic carbon to fossil carbon in the incinerated waste is determined and recorded according to quantity and duration. When optimizing the operation, the location of the waste in the bunker, from which the incinerated waste originates with a composition or variability that has now been ascertained using the method, is used to further remove or mix the waste.

Method for operating gas turbine below nominal power thereof

Номер: RU2645184C2

FIELD: oil and gas industry. SUBSTANCE: method for operating a gas turbine below the nominal power thereof, comprising determining a lower power threshold value of the gas turbine as the power parameter below which additional lowering of the output gas turbine power causes the gas turbine to leave a carbon monoxide emission-compliant partial load range of the gas turbine. Specified threshold value for an output gas turbine power is set, wherein the specified threshold value is less than the nominal power of the gas turbine. Gas turbine is operated at an output gas turbine power above the specified threshold value (p 2 ) at a constant averaged exhaust gas temperature or with an output value calculated on this basis. Inlet guide blades of a compressor of the gas turbine are closed further in order to reduce the output gas turbine power. Specified output gas turbine power is lowered when the output power falls below the threshold value. Temperature of the exhaust gases of the gas turbine is increased with continued reduction of the gas turbine power and is reduced until the maximum value of the temperature of exhaust gases is reached. Specified threshold is selected so that the temperature rise occurs in the maximum extended carbon monoxide emission-compliant partial load range of the gas turbine.

Field of the Invention The present invention relates to an emulsion fuel combustion system for producing and burning W / O (water in oil) emulsion fuel in which water is dispersed in liquid fuel (light oil, kerosene, heavy oil, gasoline, etc.). After measuring the amount of air pollutant discharged, the measured value is compared with the set value to increase or decrease the amount of water supplied to the combustion auxiliary device, so that the combustion state of the emulsified fuel is always kept good, and the liquid fuel and water are kept in the mixer. After preliminary emulsification by means of emulsification, the emulsification state is stabilized without emulsifier because it is emulsified secondly by shear, collision, compression, and expansion action by the main part, convex part of stator, blade and orifice of stator in blade and orifice of rotor. Emulsified fuel combustion system that can supply emulsified fuel quickly as well as continuously supply emulsified fuel to boiler Relate to.

이 발명은, 질소산화물의 배출 농도와 설정된 질소산화물 농도와의 편차를 계산하고, 설정값보다 높은 배출 농도 발생시 상대출력 신호를 보정하여 연료배분밸브의 개도 조정을 통해 가스터빈 운전중 연소과정에서 생성되는 질소산화물(NOx)의 농도를 자동으로 저감시키며, 자동 보정진행중에는 적분동작 로직을 통해 밸브가 급격하게 동작하지 않도록 구성하여 운전중 화염상태가 급변하여 연소 불안정 발생 상황을 사전에 예방할 수 있으며, 연소상태의 이상을 사전에 감지하고 로직상 보정 중단조건도 추가함으로써 연소 안정성을 해치지 않는 범위 내에서만 동작되도록 하는, 가스터빈의 질소산화물 농도 자동 제어장치 및 방법에 관한 것으로서, 연소실 연료분사 차압신호를 읽어와서 차압이 일정치(2bar) 미만인지를 판단하는 단계와, 연소실 연료분사 차압신호로부터 차압이 일정치(2bar) 미만인 경우에 비상제어 동작신호가 로직 '1'인지를 판단하는 단계와, 비상제어 동작신호가 로직 '1'인 경우에 PLS 신호가 로직 '1'인지를 판단하는 단계와, 질소산화물의 농도값을 읽어들여서 질소산화물의 농도값이 일정치(200ppm) 이상인지를 판단하는 단계와, 질소산화물의 농도값이 일정치(200ppm) 이상이 아닌 경우에 질소산화물의 농도값의 하락추이가 1분당 일정치(10ppm) 이상인지를 판단하는 단계와, 연소실 연료분사 차압이 일정치(2bar) 미만이고 비상제어 동작신호가 로직 '1'이고 PLS 신호가 로직 '1'이거나 질소산화물의 농도값이 일정치(200ppm) 이상이거나 질소산화물의 농도값의 하락추이가 1분당 일정치(10ppm)이상인 경우에 보정값을 '0'으로 설정하는 단계 와, 질소산화물의 농도값의 하락추이가 1분당 일정치(10ppm) 이상이 아닌 경우에 목표값과 현재값의 편차(목표값-현재값)를 연산하고 적분 연산 로직을 이용하여 보정값을 출력하는 단계와, 발전기 출력을 읽어들여서 보정값을 합산하는 단계와, 보정된 값에 따라 연료배분밸브 개도 기준값을 설정하고 연료배분밸브를 제어하는 단계를 포함하여 이루어진다. 연료배분밸브, 연소실, 연료분사, 차압, 발전기
