This module for the production of hot water is specifically designed for educational aims and it can be easily connected with dissipation modules. It includes a hot water boiler with oil burner, the relevant safety devices and utilities, as well as a system for the distribution of water to the users; it consists of visible and easy to access industrial components and instruments, correctly connected and operating.
TRAINING PROGRAM
• Procedures for:
– water filling and air bleeding from the system
– draining and checking system tightness
– starting the plant and checking the operation of safety devices and of boiler protections
• Protection devices of a machine room
• Safety devices of a machine room
• ON/OFF control: analysis of the operation of the thermostat controlling the hot water production temperature: recirculation pump operation
• With optional item flue-gas analyzer:
– evaluation of boiler combustion efficiency
– variation of air and fuel flow to the burner and verification of the effects on combustion efficiency
– assessment of the quality of the coupling between burner and boiler
