GAS FURNACES INSTALLATION CERTIFICATION Cer tification Infor mation Scope - Tests a candidate´s knowledge of the..
The sequence of the heating surfaces along the direction of the flue gas flow is as follows: festoon, ECO2, and ECO1. In the combustion chamber and the festoon (up to the first rows of ECO2), radiation plays a significant role in the heat transfer process. ECO2 is composed of finned...
availability for power generation purposes. Under program control, completion of one sequence step generally initiates the next sequence step unless a shutdown alarm occurs. Plant availability is further advanced by startup sequencing which provides for multiple ignition attempts in the event of ignition...
[3] studied oxygen balance and scheduling under blast furnace shutdown conditions and established a scheduling model for air separation startup and shutdown based on mixed integer linear programming [16]. Xu et al. [17] proposed a production scheduling optimization model that was built to ...
1. The lighting sequence on this appliance is automatic; do not attempt to manually light the main burner. 2. If the furnace does not come on when the thermostat is set several degrees above room temperature, set the thermostat to the bottom of its range to reset safety control. 3. ...
- Air pressure supervision with functional check of the air pressure switch during startup and operation. - Electrical remote reset facility - Multicolor indication of fault status and operational status messages - Limitation of the number of repetitions - Accurate ...
