摘要： A three-mode analog controller, for regulating a signal (E 1N ) corresponding to a control variable to produce a controller output (E ouT ), comprises an integrating circuit (58), a proportional circuit (70), and a derivative circuit (82). The integrating circuit (58) includes a reset adjustment for varying a time constant thereof, the proportional circuit (70) includes a gain adjustment for varying the gain thereof, and the derivative circuit (82) includes a rate adjustment for adjusting the rate of derivation of the signal. The gain adjustment comprises a photoresistor (76) associated with a source of light (74) which is provided with varying current to vary the resistance of the photoresistor (76) and, thus, the gain value. The reset and rate adjustments may also comprise photoresistors with light sources or may be formed of field effect transistors each controlled by a circuit and a remotely located potentiometer or variable voltage source.

摘要： Aflame monitor for a burner (10) comprises an oscillator (30) which generates a signal'at a characteristic frequency (f), a flame modulator (26 or 36) connected to the oscillator (30) and the burner (10) for modulating the flame, which produces an electromagnetic signal at the same frequency, and a signal detector (34) for detecting the electromagnetic signal. A bandpass filter (40) is connected to the detector (34) for passing only the signal at the characteristic frequency. Circuitry (44,46) is provided for detecting the intensity of the electromagnetic signal, which is proportional to the flame temperature and which can be used to control the fuel or air supplied to the burner and thus optimise the flame. A single detector can be used to detect the flame from various burners where each burner is supplied with its own characteristic frequency and the detector is multiplexed to share its operation over the various burners. A pressure wave detector is also provided to detect the intensity of a pressure wave in the flame, which intensity is divided into the electromagnetic radiation intensity to provide a calibration signal.

摘要： A method of minimising combustion operation losses includes measuring (40) a load index for the combustion operation which is proportional to the fuel demand or the output thereof, measuring an amount proportional to the air heating losses of the combustion operation and measuring an amount which is proportional to the fuel loss of the operation. The air heating loss is measured by multiplying (34) a flue temperature (30) by an amount of unburned oxygen in the flue gas. This quantity is multiplied (42,44) by a cost factor for such air heating and the load index. The fuel loss is obtained by measuring (46, 48, 50) an amount of by-product in the flue gas as well as the opacity of the flue gas. These are multiplied (56, 58, 60) by appropriate cost factors which in the case of opacity is proportional to a fine that would be due for violating certain limits for the opacity. Minimum values are found for the fuel loss and air heating loss quantities, as air demand to the combustion operation is changed. A minimum for the sum of the fuel and air heating losses is also obtained with the air demand of the combustion operation being set so that all of the losses are as low as possible. In this way the costs of undesired air heating. unburned by-products as well as potential violation of flue gas characteristic limits are utilised in determining the most economical air demand for the combustion operation.
摘要翻译： 一种使燃烧操作损失最小化的方法包括测量（40）与燃料需求或其输出成比例的燃烧操作的负荷指数，测量与燃烧操作的空气加热损失成比例的量，并测量 与操作的燃料损失成比例。 通过将烟道温度（30）乘以烟道气中未燃烧氧的量来测量空气加热损失。 该数量乘以（42,44）这样的空气加热和负荷指数的成本因子。 燃料损失是通过测量（46,48,50）一定量的烟气中的副产物以及烟道气的不透明度来获得的。 这些乘以（56,58,60）适当的成本因素，在不透明度的情况下与违反某些不透明度限制的罚款成正比。 当燃烧操作的空气需求改变时，燃料损失和空气加热损失量的最小值被找到。 在燃烧运行的空气需求设定为使得所有的损失尽可能低的情况下，也可获得燃料和空气加热损失之和的最小值。 以这种方式，在确定用于燃烧操作的最经济的空气需求时，利用不期望的空气加热，未燃烧的副产物的成本以及可能违反烟气特性极限的成本。
