Bench For The Study Of Wall-Mounted LPG Boiler Refrigeration Trainer Technical Training Equipment

GPL-G Bench For The Study Of  Wall-Mounted LPG Boiler Refrigeration Trainer Technical Training Equipment

This bench is equipped with a set of several instruments for measuring the parameters that characterize the operation of an open-type boiler with airtight chamber fed by LPG.
TRAINING PROGRAM
• This bench enables to develop theoretical-practical lessons concerning combustions stoichiometry in various conditions, besides detecting:
- Instantaneous efficiency
- Seasonal efficiency
- Combustion efficiency (optional item flue-gas analyzer FGA-1 or FGA-E required) and filling in proper tables with the resulting values
• This bench is also prearranged for the insertion of hydraulic and electric faults to show any malfunction occurring during everyday operation
TECHNICAL SPECIFICATIONS
• Colour schematic diagram showing the water and gas circuits entering and coming out of the boiler
• Power and safety switchboard with potentiometer for the simulation of outdoor temperature
• Modulating airtight chamber boiler fed by LPG, with automatic fault detector, outdoor reset control, water/water exchanger for sanitary hot water production, flowmeter to modulate the flame for sanitary uses
• 1 LPG pressure regulator

• 1 LPG volumetric meter
• 2 heat counters provided with flowmeter and thermocouples for measuring the thermal jump
• 1 thermometer for the continuous temperature control in the combustion chamber via S-type probe. This instrument relates combustion temperature to the efficiency and to the presence of nitric oxides in flue gas (that can be detected by the optional instrument FGA-1 with NOx cell)
• 1 thermometer for the continuous temperature control in the chimney via J-type probe
• 1 external water/water exchanger for cooling the heating water. Water circuits are provided with the necessary usual accessories for a correct operation
• 1 wash basin provided with mixer for drawing warm and cold water, for a visual check of the operation
• Manifolds for the hydraulic connections with other units
• 1 section of chimney with butterfly damper to modify its draught
