AC drive implementation and reduction of minimum load
The AC-Drive installation is an option applicable to burner systems with separate FD-Fan i.e. steam atomizing burners etc.
The main benefit is reduction in minimum load. In many cases the size of the boiler plant on Tankers is based on cargo handling situations with very high steam demand. Normally, the turn down ratio on large auxiliary boilers is approximately 1:5 and this will often give a minimum load that is to high for continuous operation in periods with low steam demand.
Other benefits are:
Reduced starting current. Are you running two generators to cope with power demand during boiler start
