US 12,410,754 B2 · Dual-fuel power system and air supply and purging method thereof

Abstract

A dual-fuel power system and an air supply and purging method thereof are provided. The dual-fuel power system includes a plurality of dual-fuel power devices, a first air compressor and a second air compressor. Each of the plurality of dual-fuel power devices includes a compressed air supply pipeline, a first fuel nozzle and a second fuel nozzle, and the compressed air supply pipelines of the plurality of dual-fuel power devices are connected in sequence. The first air compressor includes a first air storage cylinder connected with the compressed air supply pipeline of any one of the plurality of dual-fuel power devices to supply air to the plurality of dual-fuel power devices; and the second air compressor includes a second air storage cylinder connected with the compressed air supply pipeline of any one of the plurality of dual-fuel power devices to supply air to the plurality of dual-fuel power devices. Thus, the plurality of dual-fuel power devices can be supplied with air through the second air compressor when the air supply from the first air compressor is insufficient.
