Working Principle
The high pressure fuel gas system is designed for MAN ME-GI engines. The system consists of “B” and/or “C”type storage tanks, BOG compressors, spray pumps, service tank, boost pumps, sleeve tube heat exchangers….The BOG compressor will be running for supply BOG to generator or boiler at abt. 6bar. Extra BOG, that means BOR larger than consumption rate by generator engines, will be by-passed to service tank through pre-cooling section of sleeve tube heat exchanger for “self-balance reliquefaction”. One of spray pumps will be running continuously and supply liquid fuel with abt -160 deg.C to the service tank. The pressure in the service tank is keep at 10 bar and the temperature at abt -130 deg.C. The self-balance reliquefaction only takes place when main engine running and main engine consumption rate is more than 6 times of extra BOR. One of boost pumps is continuously running and supply liquid with 315 bar to sleeve tube exchanger for vaporizing and heating.
Feature
● Self-balance reliquefaction saves installation cost.
● Sleeve tube heat exchanger make it easy for fabrication and reliable.
● Very low power consumption of the system.
● Simultaneously satisfy the HP main engine and LP auxiliary engine.
