TVPLC Устройство распространение и устойчивости пламени, управляемое с ПК

The Computer Controlled Flame Propagation and Stability Unit, "TVPLC", is a teaching unit which allows to obtain various flames by changing the quantities of the fuel – comburent mix. The unit is prepared to work with different gaseous fuels, so it makes it possible to study the differences between them.

The "TVPLC" unit consists of a vertical burner, which will be lit by a lighter. It consists of different installations or circuits which are described below:

• Air circuit: it supplies the burner with the necessary comburent for the combustion process. It is composed of a fan and a solenoid valve, usually open. There is a manual regulation valve to adjust the required air flow. The circuit includes a flexible tube for an easy connection to the burner.
• Fuel gas circuit: it is composed of two solenoid valves, usually closed due to safety reasons. It is completely made of stainless steel. There is a manual regulation valve to adjust the required gas flow.
• Safety elements. It is important for the student to familiarize with the different safety elements which can be implemented in a combustion installation. The burner is protected by a box made of stainless steel which acts as physical barrier between combustion process and user.
• Flame propagation accessory: Structure made of aluminum profiles. Panels are made of PVC in order to lighten the unit. It consists of a transparent PVC 5 meters long hose to be able to view the experiment. The ignition process is carried out by a spark plug installed at one end.
• Instrumentation and sensors for the correct study of a combustion process flame. Mainly, the flows, temperatures and pressures of air and gas lines are studied.

A camera is provided to be installed together with the computer (PC). Thus, photographs of the different flames can be obtained.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
