    APPLIANCE DESCRIPTION ECOVAPOR Systems are automatically-operated appliances for high pressure (12 bar) steam production from 350 to 3000 kg/h. The horizontal combustion chamber is of the reverse flame type and the tube bundle is complete with helical turbulators. The patented combustion system, with pre-mixing and flue gas recirculation, only for natural gas (CH4), allowing to obtain high efficiency levels, low emissions and a thermal power modulation from 1 to 10, is integrated inside the front door and in the rear smokebox.

    IMPORTANT To define the desired position, refer to the two marks (1) present on valve handle. Three-way valve SAFETY VALVES The safety valves are able to maintain the pressure in the generator to the design pressure (save temporary peaks of 10% max of the max PS of the whole) even if all other pressure control devices (pressure switches and transmitters) are out of use.

  • Page 17: Safety Pressure Switch

    use and maintenance manual is supplied with the safety valves. In case of conveyed drain, blow the conveyor pipe so as to compensate the reaction force generating upon fluid drainage (refer to the valve use manual supplied with the appliance). Make one or more draining holes in the conveying pipe to drain any condensate.

  • Page 18: Pressure Transducer

    PRESSURE TRANSDUCER The 0 - 16 bar (4 - 20 ma) pressure transducer detects the steam pressure inside the generator and converts it into a current value, then transmits it to the control panel supervising generator operation. IMPORTANT The technical specifications of this device are available in the manual supplied with it. CAPACITIVE PROBE The capacitive probe, combined with the pre-amplifier, has been designed for the adjustment or ON-OFF control of the conductive liquid level.

  • Page 19: Combustion System

    Combustion system DESCRIPTION ECOVAPOR The steam generating system is equipped with a patented combustion system with premixing and external recirculation, integrated into the boiler, with vector flame development, characterised by the presence of a suction fan in the rear part. Therefore, the mixing-combustion process occurs under depression, preventing any possible leakages and further increasing the safety level.

  • Page 20: Safety And Control Systems

    SAFETY AND CONTROL SYSTEMS For the correct operation of the combustion system through: – safety pressure switch on the air side to stop the combustion in case of fan abnormal operation – combustion management system consisting of a flame electronic supervisor, interconnected with the steam production control system.
  • Page 21 BURNER MODULATION STRATEGY The burner is of the modulating type with PID (Proportional - Integral - Derivative) control. The burner starts when the measured steam pressure is under the setpoint value shown in the operator panel of the control panel, less the ignition differential, while it stops when the measured steam pressure reaches the setpoint value plus the turning off differential.
  • Page 22 SYSTEM LOGICS ECOVAPOR IN CASE OF NO FLAME ECOVAPOR Hereinafter is the description of the logics that the System executes if the burner flame, due to a failure, does not turn on or if the flame is not detected upon ignition, or if it turns off during operation. FAILURE UPON IGNITION If the burner is not able to turn on the flame, the system closes the pneumatic gas valve and repeats the ignition phase twice (each attempt is preceded by a leak test of the gas valve).
