Abstract:
A combustion system includes a combustion chamber, a plurality of fuel introduction locations in the combustion chamber where fuel and air are provided to the combustion chamber for combustion, a fluid flow control device associated with each fuel introduction location, each fluid flow control device being controllable to vary an amount of the air supplied to each fuel introduction location, a plurality of sensing devices configured to monitor a plurality of operational parameters of the combustion system, and a control unit configured to control each fluid flow control device to control the amount of air supplied at each fuel introduction location independent of the amount of air supplied at the other fuel introduction locations, and to control the amount of air provided to all other air introduction locations, in dependence upon at least one of the plurality of operational parameters to minimize excess air provided to the combustion chamber.
Abstract:
A regulator for a solid fuel heater comprises a fan (8), at least one variable air valve (7) and a controller, and two or more sensor inputs. The controller is arranged to control air flow to a primary air input and a secondary air input of the heater based upon readings taken from the sensors. Sensors comprise at least a combustion chamber temperature sensor, and at least one of a CO, 02, NOx, S, and a particulate sensor. The controller is adapted, in one mode of operation, to control airflow to the primary air input based upon the temperature or gas/particulate sensor(s), and to control air to the secondary air input based upon the gas/particulate sensor(s). A remote control device may be used to communicate with the controller for ease of operation and may contain a temperature sensor that may act as a thermostat. The invention is particularly suited to use with wood fuelled heaters, where it may be used to reduce undesirable emissions.
Abstract:
A method for measuring and controlling flame quality in real-time, the method comprising the steps of: acquiring a plurality of flame images in a first field of view; acquiring a plurality of flame images in a second field of view; processing the acquired plurality of flame images of said first and second fields of view to determine an overall flame quality parameter; and comparing the overall flame quality parameter to a tolerance range. In other aspects, a system for measuring and controlling flame quality in real-time and a non- transitory computer readable medium (CRM) storing instructions configured to cause a computing system to measure and control flame quality in real-time are provided.
Abstract:
In an embodiment, a method includes performing a turbine combustor diagnostic routine including operating a first turbine combustor of a plurality of turbine combustors at a substantially steady state of combustion; adjusting an operational parameter of the first turbine combustor to cause a change in combustion products produced by the first turbine combustor; identifying a first sensor response of a first subset of a plurality of sensors disposed within or downstream from a turbine fluidly coupled to the turbine combustor, the first sensor response being indicative of the change in the combustion products, and wherein the first subset comprises one or more first sensors; correlating the first subset of sensors with the first turbine combustor; and diagnosing a condition of the first subset of the plurality of sensors, the first turbine combustor, or a combination thereof, based on the first sensor response.
Abstract:
A method for real-time burner monitoring and control of a flare system (130), including analyzing a flare gas and/or flare exhaust gas by one or more analytical techniques and determining the flare gas (12) and/or flare exhaust gas composition. The method may also include an ash particle monitoring system. The method further includes an analytical control unit (150) for real-time adjustment of process conditions.
Abstract:
A method for controlling a thermal process, which produces energy and/or fuel in a thermal device. The method comprises producing some gaseous compound comprising measurable particles and conveying at least part of the gaseous compound comprising measurable particles to an analyzer. The method further comprises detecting, using the analyzer, the electric charge of at least some of the particles of the gaseous compound comprising measurable particles; providing information indicative of the electric charge of at least some of the particles; and controlling, by a flow controller and by using the information indicative of the electric charge of at least some of the particles, a flow into or out of the thermal device. In addition, a corresponding thermal system.
Abstract:
A sampler comprises an ejector (100) and a sample channel (112) extending to the ejector (100), which are placeable in a mixture (102) of particles of a solid and a medium, the medium being a gas and/or a liquid. The ejector (100) comprises at least one inlet (108) and an outlet (116). The ejector (100) takes a mixture sample (110) by using vacuum via the inlet (108) and discharges it via the outlet (116) so as to make the mixture sample (110) flow from the inlet (108) towards the outlet (116). The sample channel (112) takes a desired measuring sample (122) from the mixture sample (110) flowing in the ejector (100), the solid particles and the medium being at least partly separable from one another in the ejector (100) on the basis of the flow and inertia in the mixture sample (110).
