GAMBARAN UMUM

The Computer Controlled Marcet Boiler Unit "TECMC" is an unit designed to demonstrate the relationship between pressure and temperature of the saturated steam for comparison with published results.

The unit consists of an insulated stainless steel pressure vessel (water boiler), an immersion heating element, a safety valve, a high pressure switch, pipes with regulation valves, a pressure sensor and a temperature sensor.

A defined amount of water is heated in the boiler using an immersion heating element (computer controlled). The heating element has a thermostat to limit the maximum heating temperature.

A safety valve and a high pressure switch limit the maximum boiler pressure. The saturation pressure curve can be determined up to a pressure of 18 bars.

For safety purposes, a pipe with a regulation valve, situated in the lower side of the boiler, allows the boiler to be filled with water using a hose. Another pipe with a regulation valve, situated in the upper side of the boiler, allows the checking of the water level using a hose. Both pipes allow the draining of the water from the boiler and to direct any vented steam away from the working area to a suitable drain.

A temperature sensor and a pressure sensor measure the properties of the saturated steam in the boiler.

This unit is protected by transparent sheets with orifices to allow handling the valves.

The process control is done from the computer using EDIBON control software. This software will allow an automatic control (PID) of the saturated steam temperature with the heating element.

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.
