Tesca Utility Boiler 32453 is a typical drum-type boiler widely used in the oil refinery and petrochemical plants for steam generation.
Tesca Bench Top Utility Boiler Simulator Model 32453 is designed to demonstrate the
thermodynamic basic principal of boiling phenomenon.
32453 enables user to study the fundamental pressure- temperature relationship of saturated steam in equilibrium with water.
The Boiler consists of a stainless steel pressure vessel fitted with a high pressure immersion electrical heater.
It comes with a safety valve, temperature sensor and Bourdon type pressure gauge. Water inlet valve and discharge valve are also installed.
32453 comes with transducers for temperature and pressure for students to enable to take readings for respective values on a digital indicator.
Heater power supply is controlled through control panel. The heater is protected from burn-out by setting the maximum operating temperature on the temperature controller.
Optionally Data Acquisition System can be offered for Data Logging; Signal Analysis; Process Control; Real-time Display; Tabulated Results & Graph of Experimental Results Utility Boiler Module consists of Simulator and Tutorial.
