摘要
A proportional heater controls a marine diesel powered generator with a diesel particulate filter (DPF). A proportional control is applied to the heater based upon exhaust temperature. The heater heats exhaust gas to a regeneration temperature to remove soot and sulphur from the processed gas when the diesel fuel has a sulphur content exceeding 1,000 ppm. The heater is supplied power via SCRs to reduce electromagnetic and radio frequency interference. A manual override permits the operator to set a temperature setpoint, force the heater to meet a certain temperature and establish a load bank for diesel engine electrical generator set.
