General Description
The Computer Controlled Combustion Laboratory Unit, "TVCC", unit is mounted on a metallic frame that enables safe access to the equipment and an easy handling and access to the burner, combustion chamber and all the accessories and control panels.
The burner starts the combustion with fuel oil (diesel or gas oil) or with gas (natural gas or LPG). The gas (either from an LPG cylinder or from the premises’ supply) and fuel oil stored in two tanks provided with the unit are fed to the burner through suitable ducts and valves.
Both lines include their corresponding filter and the appropriate safety measures. Prior to the combustion start, the burner begins with an air purge, later on it burns the corresponding fuel and, automatically, it is set to a safe working conditions.
The burner has an integrated fan that provides the air required for the combustion, a flame detection sensor and an ignition controller. This fan has a differential pressure sensor to measure the air flow provided, a thermocouple to determine its temperature and a regulator for the air flow to be introduced in the burner.
The flame burns inside a stainless steel combustion chamber cooled with water. Such chamber has five observation points (of 100 mm) at their sides which allow to observe the flame.
The unit also includes a manual digital analyzer for the combustion fumes. It allows to determine the composition of such gases, the air excess, content in O2, CO, CO2 and CO/CO2 ratio.
This way, students can study the effect of the fuel/air ratio in the characteristics of the flame, in the efficiency of the combustion, in the constituents of the combustion fumes, etc., as well as the influence of all these aspects in the use of different fuels.
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.
